## Title
Disparate live media output stream playout and broadcast distribution

## Abstract

A stream playout and distribution system is provided for disparate live media output stream playout and broadcast distribution. The system generates a new version of a disparate live media output stream manifest based on insertion of a plurality of segments of at least one of a pre-encoded media asset or a live input stream into the disparate live media output stream manifest. Each segment of the plurality of segments corresponds to a different quality level and a different content encryption mode. The plurality of segments corresponds to broadcast content segments encoded in a first encoding format of the new version of the disparate live media output stream manifest. The system converts the broadcast content segments encoded in the first encoding format to a second encoding format in accordance with a broadcasting protocol.

FIELD OF TECHNOLOGY
Certain embodiments of the disclosure relate to a television content packaging and distribution system. More specifically, certain embodiments of the disclosure relate to a method and system for disparate live media output stream playout and broadcast distribution.
BACKGROUND
The past decade has witnessed a massive expansion of live web simulcast services in the field of advertisement-based broadcasting and cable networking systems. Broadcasting platforms usually refer to types of networks that are used to deliver media content to viewers. Currently, all the broadcasting platforms, such as analog terrestrial broadcast, digital terrestrial broadcast, direct-to-home satellite broadcast, cable, Internet Protocol (IP), and over-the-top television (OTT), compete and strive to increase their appeal in order to gain wider audience.
Modern web streaming protocols, such as HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH), are implemented to support streaming of live content services, such as DIRECTV NOWSM, SLING TVSM and PLAYSTAYIONTM VUE, to consumer devices. Traditional service providers, such as COMCASTSM, also have set-top boxes capable of receiving both legacy broadcast distribution protocols, as well as modern web streaming protocols. However, such traditional service providers are constrained by the number of broadcast channels they can support on the legacy infrastructure and are more likely to allow more niche-based programming using Internet-based distribution.
Technically, such modern web streaming protocols break media content into numerous small broadcast content segments, typically less than 10 seconds in length. Modern web streaming protocols further implement a manifest that corresponds to a dataset that may instructs a media player what broadcast content segments to retrieve and play next.
The modern web streaming protocols further support pre-encoded media assets, such as video-on-demand (VOD) assets, and a live input streams, such as live media content, as well. The VOD assets prepared for web distribution may have a sequence of short duration video segments as well as a pre-encoded media asset manifest. The sequence may include separate physical files or pointers (real or to be calculated) to the short broadcast content segments inside a larger file. The pre-encoded media asset manifest may specify all the video segments that make up the full length of the pre-encoded media asset. Alternatively, the pre-encoded media asset manifest may include instructions for the media player to be able to determine all the video segments of the pre-encoded media asset.
On the other hand, in case of live input streams, new short live broadcast content segments may be made available as soon as they are created. In some protocols, each new short media content segment is added to a live input stream manifest while in others the media player is provided necessary information to determine the next live media content segment. In the latter case, an inband signal in the live media content segment is used to inform the media player to re-inspect the live input stream manifest for a change in the live media content segment.
The pre-encoded media asset manifest, the live input stream manifest, and/or the broadcast content segments (in the pre-encoded media asset and/or the live input stream) may also include and/or specify additional information to facilitate the media player to transition smoothly between media content streams from different sources. The manifest may be used for creating a playlist of multiple media content files, or for interrupting media content stream with advertising and then resuming the media content stream.
Typically, in the broadcast industry, a live channel consists of media content that is pre-produced. A broadcast air chain may include expensive infrastructure to create an “Air Master” file, decode and play the “Air Master” file from a server, overlay channel branding graphics, and then encode it for broadcast distribution. The distribution of the live channel typically takes place over satellite. As the Internet is rapidly changing how video is delivered, several new Internet protocols are being developed to replace the need for expensive transport such as satellite transport. Such solutions are gaining popularity for channels with a limited number of receive locations, but the solutions do not address the high cost of the channel production itself or delivery to numerous receive locations. In other words, such solutions are expensive and lend to single channels covering respective wide geographic areas. Such solutions also fail to recognize that existing delivery protocols, such as HLS and DASH, are sufficient, in many cases, to produce and deliver channels at scale over a traditional content delivery network for a much lower cost.
Given the trends toward media content distribution using internet protocols, there is required a system to eliminate the need for a high cost broadcast infrastructure to generate and distribute live channels using existing pre-encoded media assets prepared or live input streams for distribution by leveraging an understanding of modern web streaming protocols and the latest techniques used in satellite distribution. Thus, an advanced system may be required that provides the network provider with the capability to not only generate and distribute new channel offerings in cost-effective manner, but also provide enhanced viewer experience to increase their appeal in order to gain a wider audience.
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present disclosure as set forth in the remainder of the present application with reference to the drawings.

Other separation and/or combination of the various entities of the exemplary stream playout and distribution system 104 illustrated in FIG. 1 may be done without departing from the spirit and scope of the various embodiments of the disclosure.
The media packaging and distribution system 102 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code that handles media content comprising audio, video, images, metadata, manifests, and/or other data (embedded and/or externally referenced). The media content may include a video, an audio, a combination of audio and video presentations, and/or embedded or externally referenced metadata, a combination of multiple-audio, multiple-video, and/or embedded or externally referenced metadata. Accordingly, the media packaging and distribution system 102 provides disparate live media output stream playout and broadcast distribution.
In this regard, the media packaging and distribution system 102 may provide video programming services to viewers, usually for a subscription fee (such as pay television). The media packaging and distribution system 102 also handles distribution, for example, multicasting, unicasting, broadcasting, streaming, for one or more channels to be viewed on one or more of the plurality of consumer devices 110a, . . . , 110n. 
The media packaging and distribution system 102 may be operated by an entity related to handling or distribution of media content, for example, a broadcast provider or operator, or a network provider or network operator. The entity related to handling or distribution of media content may also be referred to as a content owner, a distributor, a syndicator, a re-distributor, a content aggregator, a search, discovery, or cataloging service provider, or any other entity actively or passively involved with the distribution, cataloging, or referencing of complete or partial presentations of media content. Throughout this document, the terms broadcast provider or broadcast operator, and network provider or network operator may be utilized to refer to the entity related to handling or distribution of media content, interchangeably. The broadcast provider may handle a single channel or a plurality of channels, or one or more networks. The broadcast provider may be configured to distribute content via one or more platforms, for example, traditional over-the-air broadcast channels, radio, cable television networks, satellite communication networks, the Internet, and/or other content delivery networks (CDNs). In this regard, the broadcast provider may be configured to execute code that communicates linear video feeds (also referred to as a network television feed or broadcast feed) to the media packaging and distribution system 102. In a broadcast chain, the broadcast provider may receive actual content, for example, from a production studio, in a serial digital interface (SDI) video interface and/or on a high-definition SDI (HD-SDI) video interface, process the content, such as insertion of graphics, closed captions, preparation of programming schedule, insertion of triggers, and the like, and final delivery by a broadcasting apparatus. The communicated linear video feed and the playout schedule may correspond to a channel, such as CNN channel that is provided to the media packaging and distribution system 102, via a network. The linear video feed may be provided as a multi-program transport stream (MPTS). In an embodiment, the live stream encoder/packager 116 may be configured to convert the MPTS to web distribution protocols prior to feeding to the media packaging and distribution system 102, via a network. The broadcast provider may be owned by (or associated to) a broadcast provider or operator, a network provider or operator, or a content provider or operator.
The media packaging and distribution system 102 may receive the MPTS, which includes the signaling content and metadata, from the broadcast provider based on, for example, current society of cable telecommunication engineers (SCTE) standards (SCTE-35 and SCTE-224) to control web and regional blackouts, network end of day switching, and advertisement insertion. For example, the media packaging and distribution system 102 may be signaled for various blackout types with in-band SCTE-35 message. Further, the media packaging and distribution system 102 may receive program metadata that specifies certain events or operations, such as, for example, when to blackout shows. The media packaging and distribution system 102 may benefit various entities, for example direct-broadcast satellite (DBS) providers, cable television (CATV) systems, and other wireline video providers and competitive local exchange carriers (CLECs) using, for example, IPTV.
The stream playout and distribution system 104 may comprise suitable logic, circuitry, and interfaces that may be configured to execute a code that may be configured to generate a plurality of disparate live media output stream manifests by manipulating manifests of pre-encoded media assets or pre-encoded live input streams. In accordance with an embodiment, the plurality of disparate live media output stream manifests may be generated for consumer devices 110a, . . . , 110n based on respective ability to support one-to-one targeted insertion of non-programming content, such as ads. In accordance with another embodiment, the plurality of disparate live media output stream manifests may be generated for media players, such as IP receivers, based on respective geographic locations. The stream playout and distribution system 104 may be configured to encrypt and protect (by means of digital rights management) the plurality of disparate live media output stream manifests before distribution to such media players.
The Ad decisioning server 106 may comprise suitable logic, circuitry, and interfaces that may be configured to implement at least an advertisement decisioning component that may be used during a real-time content or advertisement placement activity, for example during dynamic ad insertion. For example, commercial or non-commercial advertisements may be dynamically inserted within program segments of the live input streams based on the detected upcoming indicator, such as an inbound trigger, a signaling point, and/or a signal in a pre-encoded media asset and/or a live input stream by the Ad decisioning server 106. The Ad decisioning server 106 may receive a request for retrieval of non-programming content, for example, ads, from a non-programming content proxy server (not shown). Specifically, the Ad decisioning server 106 may receive the request from one or more of the plurality of consumer devices 110a, . . . , 110n, via the non-programming content proxy server (not shown). The request may be received when one or more indicators and/or pre-encoded place holder content segment for a scheduled duration of one or more non-programming content breaks. The scheduled durations of one or more non-programming content breaks may be defined by a received programming schedule, and are encountered in the disparate live media output stream manifest during media content playout by media players at the one or more of the plurality of consumer devices 110a, . . . , 110n. 
Thus, for requests received from the plurality of consumer devices 110a, . . . , 110n, based on corresponding disparate live media output stream manifests, the Ad decisioning server 106 may identity the opportunities for the real-time content or advertisement placement activity. In this regard, as the advertisement decisioning component of the Ad decisioning server 106 is implemented in a consumer device, such as one or more of the plurality of consumer devices 110a, . . . , 110n, the Ad decisioning server 106 may identify real-time content or advertisement placement opportunity for dynamic ad insertion. For example, commercial or non-commercial advertisements may be dynamically inserted within program segments of a media feed by the Ad decisioning server 106 based on the indicator detected by the media player or the non-programming content proxy server. The detected indicator may be, for example upcoming inbound trigger, signaling point, and/or signal, in the disparate live media output stream manifest. In various embodiments, the advertisement decisioning component of the Ad decisioning server 106 may be configured to determine which advertisements, graphical treatment graphics and presentation information to serve to the consumer devices 110a, . . . , 110n based on stream ID, a program ID, a geographical location, time, and any preferences associated with an individual consumer or an advertisement ID specified by the disparate live media output stream manifest.
The consumer devices 110a, . . . , 110n may refer to end-user devices or consumption devices where the content is played for consumption by a user. The number of impressions of a media item, such as an advertisement and/or promotional media, on such plurality of consumer devices 110a, . . . , 110n determines the advertising impact or promotion impact and number of actual audiences achieved during campaigns. Examples of the consumer devices 110a, . . . , 110n may include, but are not limited to, connected TVs, connected TV with paired and/or connected devices (e.g., HDMI sticks, tablets), personal computer, smartphone, tablet, OTT set-top, or hybrid set-top, and second screen devices such as smartphones, tablets, game consoles, personal computers, set-top boxes, and embedded devices. The consumer devices 110a, . . . , 110n may further include process/system that may process the output for any means, regardless of the capability or intent to decode for media presentation, and on which the consumer may launch a web page, a web application, or a web service to view media content.
The ad/promo campaign manager 114 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code that may be configured to receive non-programming content, such as ad and/or promotional content campaigns, from ad sales. Such ad campaigns may be sold including, for example, audience targets, creatives, length of campaign, separation rules, and the like. The ad/promo campaign manager 114 may further receive windows for the campaigns along with desired audience demographics and segments, and ad versions. The ad/promo campaign manager 114 may be configured to inform the stream playout and distribution system 104 when new ads or promos are entered in to the ad/promo campaign manager 114 by the ad sales.
The live stream encoder/packager 116 may comprise suitable logic, circuitry, and interfaces that may be configured to execute a code that may be configured to encode and package the live feeds or live source streams to generate live input streams. The live stream encoder/packager 116 may be further configured to generate a plurality of live input stream manifests corresponding to the each of the live input streams. Various media container formats of the live input streams may include, but are not limited to, transport stream (TS), fragmented MP4 (fMP4), Common Media Application Format (CMAF) and the like. Various formats of the plurality of live input stream manifests or playlists, may include, but are not limited to DASH and HLS. The generated live input streams and manifests may be used for distribution, such as Internet distribution. The generated live input streams and manifests may be further published to various the IP receiving system 155.
The content processing system 120 may comprise suitable logic, circuitry, and interfaces that may be configured to store, encode and package pre-encoded media assets and corresponding manifests. The content processing system 120 may comprise master versions of media content, corresponding metadata, and master versions of non-programming content, such as ads and promotional content. Various media container formats of the pre-encoded media assets may include, but are not limited to, TS, fMP4, CMAF, and the like. Various formats of the plurality of pre-encoded media asset manifests or playlists, may include, but are not limited to DASH and HLS.
The media content metadata storage system 122 may comprise suitable logic, circuitry, and interfaces that may be configured to store media content metadata. The media content metadata may include metadata associated with broadcast content segments stored in the media content master storage system 124. Examples of the media content metadata may include a media content identifier, a title of the media content, type of the media content (such as movie series (season episode number)), genre, plot summary, duration, advertisement break locations, credit locations, scene descriptions, a short summary of the broadcast content segments, a short summary of ideal advertisement placements within the broadcast content segments, a file format, digital right management (DRM), encryption information, length of the media content, a date and/or time the media content was added to the catalog of media content master storage system 124, a new item indicator for the media content (e.g., a new media asset that became available within the last 24 hours, last few days, last week, and/or the like), and a media content class, for example, a television show, a cartoon program, a movie, a news media, an episode, a game, a clip, a recorded sports event, interactive media, and/or the like. In general, the clip may be curated or editorially selected excerpts from existing full episodes, TV shows, or movies. In accordance with an exemplary embodiment, the media content metadata storage system 122 may also store program-specific information (PSI) data as defined by ISO/IEC 13818-1 (MPEG-2), closed captioning data, and subtitles associated with the broadcast content segments stored in the media content master storage system 124. Other forms of metadata may be utilized without departing from the spirit and scope of the various embodiments of the disclosure.
The media content master storage system 124 may comprise suitable logic, circuitry, and interfaces that may be configured to store master versions of the media content. The master versions may be used as the source for creating the on-demand or pre-encoded media assets for the IP receiving system 155 and the consumer devices 110a, . . . , 110n in the required formats. In an embodiment, various media container formats of the media content may include, but are not limited, TS, fMP4, CMAF, and the like.
The ad/promo content master storage system 126 may comprise suitable logic, circuitry, and interfaces that may be configured to store master versions of non-programming content, such as ads and promotional content. The master versions of non-programming content may be used as a source for creating on-demand or pre-encoded media assets for the IP receiving system 155 and the consumer devices 110a, . . . , 110n in the required formats.
The content encoder/packager 128 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code to generate a package that includes media content and associated metadata. The content encoder/packager 128 may receive media content from the media content master storage system 124, corresponding metadata from the media content metadata storage system 122 and the non-programming content from the ad/promo content master storage system 126 to generate the package. Thus, the content encoder/packager 128 encodes and packages the media content into the required on-demand formats for delivery to the IP receiving system 155 and the consumer device 110a. The broadcast content may correspond to one or more of the plurality of broadcast content segments transcoded to different types of streams for different types of devices, such as a TV or a mobile device, and marked with Nielson markers. Based on such a package, the stream playout and distribution system 104 may dynamically generate one or more encoded media assets for playout to one or more media players communicatively coupled through the content delivery system 160. In accordance with an embodiment, the content encoder/packager 128 may be directly coupled to the indexing and storage system 148. In accordance with an embodiment, the content encoder/packager 128 may be directly coupled to the content delivery system 160.
The content encoder/packager 128 may be configured to publish the one or more encoded media assets in real-time or near real-time. The content encoder/packager 128 may be operable to create “C3” content assets and clips that may be made available before media content rolls out of the stream playout and distribution system 104. The content encoder/packager 128 may also be configured to provide near-real-time redundancy. The resulting converted output, i.e. one or more encoded media assets, that are generated by the content encoder/packager 128 may be communicated to the indexing and storage system 148 which may be communicatively coupled with the IP receiving system 155 and the consumer devices 110a, . . . , 110n. The content encoder/packager 128 may also support a robust interface (e.g. application data interface (ADI)) that defines the on-demand duration of the individual broadcast content segments as well as encryption requirements and a service type to link for ad insertion.
For encoding and the packaging, the content encoder/packager 128 may be configured to mark locations of the one or more non-programming content breaks and condition the media content such that the locations of the one or more non-programming content breaks are adjacent to boundaries of the plurality of broadcast content segments. Based on the media content metadata, in case the one or more indicators are not included in the pre-encoded media asset at packaging time, the content encoder/packager 128 may be configured to insert the one or more indicators to mark the credits and overlay graphics locations in the media content.
Once the content encoder/packager 128 has encoded and packaged the media content based on the associated metadata corresponding to the media content assets for media distribution, the content encoder/packager 128 may be further configured to generate corresponding media content manifests. The media content manifests may correspond to data sets, such as text-based instruction sets, that may be utilized by the IP receiving system 155 and the consumer devices 110a, . . . , 110n to determine which broadcast content segments to play and storage locations of such broadcast content segments. In accordance with an embodiment, the content encoder/packager 128 may be further configured to add in-band indicators in the media content assets. The in-band indicators may indicate markers corresponding to location of the one or more non-programming content breaks, credits, and overlay graphic locations for one or more protocols that may be utilized to determine next media content asset to be downloaded.
The switch logic manager 130 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code to determine required number of disparate live media output streams. Accordingly, the switch logic manager 130 may be configured to generate a programming schedule, such as the playout schedule 112, for each disparate live media output stream based the original stream schedules and alternate content schedules. The switch logic manager 130 may generate the programming schedule based on, for example, localizations or audience segments, content rights and preferences, ad preferences, and requirements of stream owner/operator. The stream owner operator may provide one or more additional parameters to the switch logic manager 130 regarding contractual content requirements for specific locations, and historical knowledge of location preferences. The stream owner/operator may specify data about how to handle non-programming content breaks, whether to insert non-programming content between media switches, how the transition between events may be executed, whether a network logo needs to be displayed and if so how often. The stream owner/operator may further provide data, such as consumer data (for example, billing Zip code), and special service level tiers. Additionally, the stream owner/operator may provide content parameters, for example, regarding the types of channels to be generated (theme, genre, title, and the like), the number of advertisement breaks per hour, and duration of such advertisement breaks.
The programming schedule, such as the playout schedule 112, may correspond to a data set for playout of an existing first disparate live media output stream for a live channel. The programming schedule may inform the stream publishing engine 150 about pre-encoded media assets and/or live input streams as well as when and how to switch between the various pre-encoded media assets and live input streams. The programming schedule may also support defining timing for network logos, insertion of promotional graphics break durations for mid roll ads, break locations, and durations in the pre-encoded media asset and live input stream switches. In accordance with an embodiment, in case the real-time linear ad server 152 is not in use, the programming schedule may include the specific ads to be played during each break, treating such ads like other on-demand media content assets. In accordance with another embodiment, in case the real-time linear ad server 152 is in use, the programming schedule may include breaks that may be marked and filled at playout based on decisions received from the real-time linear ad server 152.
The broadcast network scheduler 132 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code to generate the programming schedule, such as the playout schedule 112, which indicates programming content, such as pre-encoded media assets and/or live input streams, and when such programming content may be played out. The broadcast network scheduler 132 may be configured to generate the programming schedule based on inputs received from the media content metadata storage system 122 and the schedule planning database 136. The broadcast network scheduler 132 may be configured to schedule the programming content based on, for example, desired channel theme, content metadata, content rights, and competitive analysis of what competing programming content is available on other channels.
The traffic system 134 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code to receive a list of programming content to be played along with the program indicators, such as program start, from the broadcast network scheduler 132. The traffic system 134 may further determine break durations and locations based on media content conditioning and an amount of time to be filled to hit the start time of the next program in the list of programming content. The traffic system 134 may further determine what non-programming content, such as ads, to place based on data, such as historical performance and competitive analysis, received from the schedule planning database 136. The traffic system 134 may further insert network rules for schedules, such as overlay graphic schedules, and the like.
In accordance with an embodiment, the traffic system 134 may check from the media content metadata storage system 122 about media content duration and break schedule.

The traffic system 134 may access the media content metadata storage system 122 to determine media content asset duration and break schedule and generate a playout schedule 112. The traffic system 134 may further determine the duration for each ad break to have the program end at correct scheduled time and have the new program start at the correct schedule time. The traffic system 134 may further communicate with the ad/promo campaign manager 114 to determine what ads and promotional content are available to be scheduled. In accordance with another embodiment, the traffic system 134 may schedule the ads to play to provide the highest yield based on historical performance. In accordance with another embodiment, the traffic system 134 may schedule a portion of the ads to play and then allow other ads to be specified by the real-time linear ad server 152. In accordance with another embodiment, the traffic system 134 may allow the real-time linear ad server 152 to specify ads to be played.
The traffic system 134 may mark an entire ad break for a downstream replacement on a consumer device, for example the consumer device 110a, that may individually target an ad. The traffic system 134 may further mark individual ads for the downstream replacement if the ads are targeted to specific audience demographics or segments, or specific geographical locations. In accordance with an embodiment, the ad/promo campaign manager 114 may inform the content processing system 120 when new ads or promotional content are entered.
The content processing system 120 may further determine whether the non-programming media content, such as the ads and promotional content, is available and has been processed to a correct format. In accordance with an embodiment, when the non-programming content is not available, the content processing system 120 may order the non-programming content. Accordingly, the content processing system 120 receives the non-programming content, assures the quality, and processes the non-programming content to a specific standard. The content processing system 120 may further store the processed non-programming content in the ad/promo content master storage system 126.
The content encoder/packager 128 in the content processing system 120 may retrieve the non-programming content from the ad/promo content master storage system 126. The content encoder/packager 128 may further encode and package the non-programming content for one or more high quality broadcast compatible profiles to support broadcast use cases.
In accordance with an embodiment, the content encoder/packager 128 may further insert in-band triggers to identify the ad or promotional content and provide special instructions for tracking when it is viewed. In accordance with another embodiment, the content encoder/packager 128 may include watermarks or in-band metadata to support ad and promotional content viewership measurements in broadcast use cases. The non-programming content may be prepared for web distribution and may be stored in the media storage unit 162 of the content delivery system 160.
The traffic system 134 may leverage channel preferences to determine when and what network logo to display, when to signal for overlay promotions, and the like. The traffic system 134 may generate the playout schedule 112 and provide playout schedule 112 to the indexing and storage system 148, and the stream publishing engine 150.
The playout schedule 112 thus generated may include manifests for live input streams and/or pre-encoded media assets, and ads and promotional content, are ingested into the indexing and storage system 148. In accordance with an embodiment, a proprietary manifest format may be there between the content encoder/packager 128 and the indexing and storage system 148 when additional information carried in the published manifest is required to be passed (not traditionally).
The indexing and storage system 148 may index broadcast content segments from each manifest corresponding to the live input streams and/or pre-encoded media assets. The indexing and storage system 148 may log indicators indicating ad breaks, program start, program end, graphic overlays, and the like. The indexing and storage system 148 may further perform checks to validate that the live input streams and/or pre-encoded media assets are complete and ready for inclusion in the disparate live media output stream.
At the schedule time, the stream publishing engine 150 may generate a disparate live media output stream manifest by inserting a new segment from the scheduled pre-encoded media asset manifest or the live input stream manifest into the disparate live media output stream manifest on an interval not greater than the previous content segment duration. For certain protocols, the stream publishing engine 150 may update at media content breaks for ads or transitions to the next programming content. The stream publishing engine 150 may further ensure correct handling of transitions between the live input streams and the pre-encoded media assets based on the channel preferences.
When the stream publishing engine 150 encounters indicators marking an ad break within the pre-encoded media asset manifest, the live input stream manifest, or the playout schedule 112, the stream publishing engine 150 may insert such indicators in the disparate live media output stream manifest. The stream publishing engine 150 may further stitch in ads and promotional content included in the playout schedule 112 and/or access the real-time linear ad server 152 to fill one or more portions of the ad break, as defined by the playout schedule 112.
The real-time linear ad server 152 may leverage the real-time audience data from sources, such as digital clients, set-top box data, smart TVs that support content recognition (CR) or ATSC 3.0 watermarks, along with traditional broadcast ad separation rules, program exclusivity rules, and the like, to determine which ads may yield the highest revenue. The real-time linear ad server 152 may provide a list of ads to the stream publishing engine 150 to be played. The real-time linear ad server 152 may mark individual ads for a downstream replacement if the ads are targeted to specific audience demographics or segments, or specific geographical locations. Accordingly, the stream publishing engine 150 may insert ad indicators and stitch ads in the disparate live media output stream manifest, as instructed by the playout schedule 112 and the real-time linear ad server 152.
The stream publishing engine 150 may transmit the output to the stream versioning engine 154 to create an appropriate variant of the disparate live media output stream manifest. The stream versioning engine 154 may receive versioning instructions from the switch logic manager 130. The switch logic manager 130 may define a number of disparate live media output stream manifests based on desired ad and content localizations, as well as ad rules for audience demographic and segment targeting. Such disparate live media stream manifest may be generated for the consumer device 110a based on its ability to support one-to-one targeted ad insertion.
In accordance with an embodiment, the stream versioning engine 154 may insert or pass through ad indicators for the consumer device 110a to replace the entire ad break with individual targeted ads and may stitch in placeholder content to replace the scheduled ads based on the instructions provided from the switch logic manager 130. In accordance with another embodiment, the stream versioning engine 154 may insert or pass through ad indicators to mark individual ads for potential replacement with targeted ads based on the user's location, known demographic information (such as females over 50 years), and known audience segments (for example auto intender for a luxury vehicle). In accordance with another embodiment, the stream versioning engine 154 may stitch in alternate programming content based on defined localizations or audience segment preferences. In accordance with another embodiment, the stream versioning engine 154 may exclude the one or more high quality profiles provided to support broadcast use cases.
When indicators marking ads for potential localization are found in the disparate live media stream manifest from the stream publishing engine 150, the stream versioning engine 154 may access the real-time linear ad server 152 to determine if there are local ads that may yield higher revenue than the already inserted ads. The stream versioning engine 154 may replace the existing ads with targeted ads in each disparate live media output stream manifest based on the instructions of the real-time linear ad server 152 for each localization zone. The real-time linear ad server 152 may abide by broadcast ad pod and program separation and exclusivity rules, and the like when determining the ad localizations. The stream versioning engine 154 may stitch in alternate program content based on the defined localizations. The stream versioning engine 154 may exclude one or more profiles created for consumer distribution.
When ad indicators are found in one of the plurality of disparate live media output stream manifest from the stream versioning engine 154, the consumer device 110a access the Ad decisioning server 106 to determine the targeted ads to be inserted. In accordance with an embodiment, the consumer device 110a may access the Ad decisioning server 106 to replace the entire break, if indicators to replace the entire break are present in the disparate live media stream manifest. In accordance with an embodiment, the consumer device 110a may access the Ad decisioning server 106 to replace individual ads, if indicators to replace the entire break are not present in the disparate live media output stream manifest and indicators to replace individual ads are present. In accordance with an embodiment, the consumer device 110a may access the Ad decisioning server 106 to include parameters to aid in targeting, such as location, or IDs that may determine demographic and audience segments.
In an embodiment, there may be ads that may be specifically marked for potential replacement based on a target demographic or audience segment or location. In such case, the consumer device 110a may determine whether it is part of the target audience demographic, segment, or location and not call for replacement. The consumer device 110a may simply pass the targeted audience demographic, segment, or location in the replacement request and the Ad decisioning server 106 may determine that the consumer device 110a is part of the target audience and not return a replacement ad.
In accordance with an embodiment, the first IP receiver 156 and/or the second IP receiver 158 in the IP receiving system 155 may be provided with correct disparate live media output stream manifests based on corresponding geolocations. In accordance with an embodiment, the disparate live media output stream may be encrypted and DRM protected. In such case, the first IP receiver 156 and/or the second IP receiver 158 may be authorized to receive corresponding disparate live media output stream. The first IP receiver 156 and/or the second IP receiver 158 may download, decrypt, and decode the broadcast content segments referenced in corresponding disparate live media output stream manifest.
In accordance with an embodiment, the first IP receiver 156 and/or the second IP receiver 158 may insert graphical treatment, such as bugs and lower third graphics, and squeeze back the video in the disparate live media output stream to provide an experience that is equivalent to the broadcast experience. The first IP receiver 156 and/or the second IP receiver 158 may convert a first format of the disparate live media output stream to a second format. The second format is compatible with what is available from a modern satellite receiver. The second format may be decoded analog, digital video, or a transcoded digital stream using a compatible codec.
In accordance with various embodiments, versions of the first IP receiver 156 and/or the second IP receiver 158 may be required to support different network and end user conditions, for example reliable and bandwidth stable Internet connection, reliable Internet connection but not stable bandwidth, unreliable Internet connection, or shared Internet condition with direct deliver to the consumer device 110a. 
FIG. 2 illustrates segmentation of live input streams and pre-encoded media assets for the playout schedule 112 for disparate live media output stream playout and broadcast distribution by the stream playout and distribution system 104 of FIG. 1, in accordance with an exemplary embodiment of the disclosure. Referring to the exemplary arrangement of FIG. 2, there is shown a first live input stream 202, a first pre-encoded media asset 204, and a second live input stream 206. There is also shown a targeted first interstitial content 208 placed after the first live input stream 202, and a second interstitial content 210 placed after the first pre-encoded media asset 204. The first live input stream 202 may be segmented into a first set of video segments 202a, 202b, 202c, . . . , 202n. Similarly, the first pre-encoded media asset 204 and the second live input stream 206 may also be segmented into second set of video segments 204a, 204b, 204c, . . . , 204n, and third set of video segments 206a, 206b, 206c, . . . , 206n respectively. By way of example, the segmentation may be executed by a segmenting system (not shown) during a preparation stage of the media assets. In accordance with an embodiment, the segments of the first set of video segments 202a, 202b, 202c, . . . , 202n, the second set of video segments 204a, 204b, 204c, . . . , 204n, and third set of video segments 206a, 206b, 206c, . . . , 206n, may be segmented into consistent length, for example, 10 seconds segments. It may be advantageous to have a consistent and smaller file size of segments to be able to quickly push to the content delivery system 160, and also for quick downloading by a media player at the end-user side, such as on the consumer device 110a. 
It should be understood by those skilled in the art that various changes may be made and segments of different file sizes (or length) may be used without departure from the scope of the present disclosure. Further, other streaming protocols may require a different processing of media content. Thus, the scope of the disclosure should not be limited to the processing or preparation of media content to allow delivery using different delivery methods, streaming protocols, or distribution system, known in the art. Further, instead of the live input streams and pre-encoded media asset arranged, as shown, different arrangements per the playout schedule 112 may be possible with respect to interstitial content items, such as the first interstitial content 208 and the second interstitial content 210. In accordance with an embodiment, the first interstitial content 208 and the second interstitial content 210 may correspond to non-programming content, such as ads or promotional content targeted for the consumer device 110a. 
The insertion of the live input stream manifests, pre-encoded media asset manifests, the interstitial content items may be done on-the-fly based on dynamic scheduling resulting in the playout schedule 112. The insertion may be driven by real-time or near-real-time content context analysis, user-selection on the consumer device 110a, or driven by external data received from an external data source. The stream publishing engine 150 may be configured to insert live input streams, such as the first live input stream 202 and the second live input stream 206, or pre-stored media assets, such as the first interstitial content 208 and the second interstitial content 210, in the disparate live media output stream based on manipulation of the disparate live media output stream manifest for corresponding live channel. In an embodiment, the stream publishing engine 150 may further exclude one or more high quality profiles created for broadcast distribution from the consumer devices 110a, . . . , 110n. 
In accordance with an embodiment, each segment of the first set of video segments 202a, 202b, 202c, . . . , 202n, the second set of video segments 204a, 204b, 204c, . . . , 204n, and third set of video segments 206a, 206b, 206c, . . . , 206n, may be further processed to be stored at various quality levels, and content encryption modes for the purposes of adaptive bitrate streaming and digital rights management, for example, the video segment 202a may be stored in a plurality of quality levels or profiles, for example, high definition (HD), high dynamic range (HDR) video, or different quality levels in accordance with specified pixel resolutions, bitrates, frame rates, and/or sample frequencies. Each of the media content, such as 202 to 206, are encoded, segmented, and stored with the plurality of quality levels in the media content master storage system 124. The media content may be re-used to create new variant channels, such as a new variant of the disparate live media output stream, without having to re-encode a selected live input stream or a pre-encoded media asset when the new variant of the disparate live media output stream is created by the stream versioning engine 154 in conjunction with the switch logic manager 130.
For the sake of brevity, and with reference to FIG. 2, there is shown an example of publishing the disparate live media output stream based on dynamic insertion of interstitial content items by the stream playout and distribution system 104 of FIG. 1. It is to be understood that media packaging for different delivery methods (such as analog terrestrial broadcast, digital terrestrial broadcast, direct-to-home satellite broadcast, cable, other Internet Protocol (IP)-based delivery methods, over-the-top television (OTT)), different streaming protocols, or distribution system, may be different. The media content may be prepared to be viewed one or more of the plurality of consumer devices 110a, . . . , 110n, based on at least the desired delivery method, delivery conditions, content protection requirements, to satisfy operational and technical requirements, as needed. The operational and technical requirements may include, but are not limited to, media encoding, media segmentation, programming schedule (or manifest) creation or manipulation requirements, desired media encryption, and/or metadata signaling requirements. For example, in certain scenarios and for certain media content delivery methods, network bandwidth, network conditions, or device-type where media content is to be consumed may not be variable or known in advance. In such a case, creating different quality levels for same media content may not be required. In other cases, for example, the stream versioning engine 154 may exclude the one or more high quality profiles provided to support broadcast use cases, or exclude one or more profiles created for consumer distribution. In some other cases, the content encoder/packager 128 may encode and package one or more high quality profiles to support broadcast use cases or include one or more high quality profiles of interstitial content items for the encoded and packaged pre-encoded media asset to support broadcast use cases. Further, based on different operational and technical requirements, publishing of the disparate live media output stream may be different. As descried above, the media content that is prepared and distributed may include both the programming content, such as long-form presentations, short-form presentations, news or sporting events; and non-programming content, such as paid advertisements, public service advertisements, or promotional material.
FIG. 3 illustrates a first exemplary scenario associated with disparate live media output stream playout and broadcast distribution by the web playout and distribution system of FIG. 1, in accordance with an exemplary embodiment of the disclosure. Referring to the first exemplary scenario 300 of FIG. 3, there are shown a first disparate live media output stream manifest 302 comprising a scheduled pre-encoded media asset and a live input stream corresponding to a live event, in accordance with a first broadcast profile. There is further shown a schedule 304 of the first disparate live media output stream manifest 302 comprising switch points between a scheduled pre-encoded media asset, a scheduled live input stream, and back to the scheduled pre-encoded media asset, in accordance with a second broadcast profile. There is further shown a live media source input stream 306 comprising only live input stream corresponding to a live event, in accordance with a third broadcast profile. The first exemplary scenario 300 illustrates integration of Live2Live to support channels with limited live content. Thus, there are provided three broadcast profiles in the live adaptive bit-rate (ABR) streaming stack. The live ABR encode may spin up only when required. For example, if the live event is scheduled from 8:00 pm to 10:00 pm, the live media source input stream 306 may switch to live encode on program start. VOD2Live schedule may be resumed on program end. Captions may need to be inserted at live ABR encode. Further, channel branding and other graphics may be inserted at the IP receiving system 155, such as the first IP receiver 156 or the second IP receiver 158. Channel branding and other graphics may also be inserted in live control room but cost may increase. Notwithstanding, both options may be supported depending on the value of the live event. In accordance with an embodiment, additional channel operator functions may be required in case the live event runs long. For example, start the next program in progress or play the next program from the beginning and make up time later.
FIG. 4 illustrates a second exemplary scenario associated with disparate live media output stream playout and broadcast distribution by the web playout and distribution system of FIG. 1, in accordance with an exemplary embodiment of the disclosure. Referring to the second exemplary scenario 400 of FIG. 4, there are shown multiple digital variations of a linear channel, such as NBA TV, shown by corresponding disparate live media output stream manifest 402. There is further shown a live media source input stream 404 for, for example NBA news feed, that may be stitched into other the disparate live media output stream manifests.
There are further shown three digital variations that may be created for, for example, three teams. For first team, there is shown corresponding disparate live media output stream manifest 406, for second team, there is shown corresponding disparate live media output stream manifest 408, and for third team, there is shown corresponding disparate live media output stream manifest 410. In respective disparate live media output stream manifests 406, 408, and 410, local team content may be scheduled at certain times of day, for example 3:00 pm to 4:00 pm. In accordance with certain embodiments, some teams may have more local content than others. Based on individual team schedules, the respective disparate live media output stream manifests 406 and 410 corresponding to the two teams may switch team versions to breaking news, such as trades or press conferences. An extra control layer may be provided to switch only relevant team versions. The capability to make last minute decision to switch for non-scheduled events is also provided. In certain cases, content rights may allow switching of team version to the team games. By using the IP receiving system 155, the first team, such as NBA team 1 variant, may be made available in the first team market as a broadcast replacement for the National NBA TV feed. With the IP receiving system 155 converting the signal back to a compatible legacy format the first team may be made available over Cable, Satellite or IPTV. For example, a cable company in the Phoenix market who chose not to carry the NBA TV national feed may now choose to carry the NBA TV phoenix variant. Alternatively, a cable company in the phoenix market who does carry the NBA TV national feed may be willing to pay more to carry the phoenix variant in addition to or as a replacement for the NBA TV national feed.
FIG. 5 depicts a flowchart illustrating exemplary operations for disparate live media output stream playout and broadcast distribution in the web playout and distribution system of FIG. 1, in accordance with an exemplary embodiment of the disclosure. FIG. 5 includes flowchart 500 illustrating exemplary operations 502 through 516.
At 502, a broadcast content schedule may be generated based on a plurality of broadcast content parameters associated with the programming content scheduled for a broadcast channel. In accordance with an embodiment, the broadcast network scheduler 132 may be configured to a generate the broadcast content schedule for scheduling the programming content based on the plurality of broadcast content parameters, such as, but not limited to, desired channel theme, content metadata, content rights, and competitive analysis of what competing programming is available on other channels. The broadcast network scheduler 132 may transmit the broadcast content schedule to the content processing system 120 and the traffic system 134 to determine whether the programming content is available and has been processed to the correct format. In accordance with an embodiment, when the programming content is not available, the content processing system 120 may order the programming content. Accordingly, the content processing system 120 receives the programming content, assures the quality, and processes the programming content to a specific standard. The content processing system 120 may further store the processed programming content in the media content master storage system 124. Accordingly, the content encoder/packager 128 in the content processing system 120 may retrieve the programming content from the media content master storage system 124. The content encoder/packager 128 may further encode and package the programming content for web distribution. The programming content may be prepared for web distribution and may be stored in the media storage unit 162 of the content delivery system 160. In an embodiment, the programming content may not available. In such embodiment, control passes to 504.
At 504, broadcast content, in accordance with one or more streaming protocols to generate a plurality of encoded broadcast content segments, may be received, encoded, and packaged based on the broadcast content schedule. In an embodiment, the content encoder/packager 128 in the content processing system 120 may be configured to receive, encode, and package broadcast content (or programming content), in accordance with one or more streaming protocols to generate a plurality of encoded broadcast content segments, based on the broadcast content schedule. Specifically, the content encoder/packager 128 in the content processing system 120 may retrieve the programming content, for example, media content asset, from the media content master storage system 124. The content encoder/packager 128 may further access the media content metadata storage system 122 to determine the media content asset duration and location of non-programming content, such as ad breaks, credits, overlay opportunities, and the like. The content encoder/packager 128 may mark precise ad break locations and condition the media content asset so that the ad break locations fall on boundaries of corresponding broadcast content segments. The content encoder/packager 128 may further insert, for example, tag indicators to mark the credits and potential overlay graphics locations in the media content asset.
The content encoder/packager 128 may further insert in-band triggers to mark the location of the ad breaks, credits, and potential overlay graphic locations for protocols that do not constantly query the manifest for new information but instead calculate the next content to be downloaded based on a defined algorithm. In accordance with another embodiment, the content encoder/packager 128 may include watermarks or in-band metadata to support program viewership measurements in broadcast use cases. The media content asset is thus prepared for the web distribution and hereinafter referred to as pre-encoded media asset. The pre-encoded media asset and the corresponding manifest may be stored in the media storage unit 162 of the content delivery system 160.
At 506, a playout schedule may be generated based on insertion of a schedule for non-programming content in the broadcast content schedule. In accordance with an embodiment, the traffic system 134 may access the media content metadata storage system 122 to determine media content asset duration and break schedule and generate the playout schedule 112. The playout schedule 112 may be generated based on insertion of a schedule for non-programming content in the broadcast content schedule. Thus, the playout schedule 112 includes the schedule for the one or more non-programming content and/or one or more programming content. In accordance with an embodiment, the playout schedule 112 for the one or more non-programming content and the one or more programming content may be generated based on the content viewing demographics.
Prior to generation of the playout schedule 112, the content processing system 120 may further determine whether the non-programming media content, such as the ads and promotional content, is available and has been processed to a correct format. In accordance with an embodiment, when the non-programming content is not available, the content processing system 120 may order the non-programming content. Accordingly, the content processing system 120 receives the non-programming content, assures the quality, and processes the non-programming content to a specific standard. The content processing system 120 may further store the processed non-programming content in the ad/promo content master storage system 126. Accordingly, the content encoder/packager 128 in the content processing system 120 may retrieve the non-programming content from the ad/promo content master storage system 126. The content encoder/packager 128 may further encode and package the non-programming content for web distribution. In accordance with an embodiment, the content encoder/packager 128 may further insert in-band triggers to identify the ad or promotional content and provide special instructions for tracking when it is viewed. In accordance with another embodiment, the content encoder/packager 128 may include watermarks or in-band metadata to support ad and promotional content viewership measurements in broadcast use cases. The non-programming content may be prepared for web distribution and may be stored in the media storage unit 162 of the content delivery system 160.
In accordance with an embodiment, the traffic system 134 may leverage channel preferences to determine when and what network logo to display, when to signal for overlay promotions, and the like. The traffic system 134 may generate the playout schedule 112 and provide the playout schedule 112 to the indexing and storage system 148, and the stream publishing engine 150. The playout schedule 112 thus generated may include manifests for live input streams and/or pre-encoded media assets, and ads and promotional content.
At 508, the manifests for live input streams and/or pre-encoded media assets, and ads and promotional content may be ingested into the indexing and storage system 148, based on the playout schedule 112. In accordance with an embodiment, a proprietary manifest format may be there between the content encoder/packager 128 and the indexing and storage system 148 when additional information carried in the published manifest is required to be passed (not traditionally). The indexing and storage system 148 may index broadcast content segments from each manifest corresponding to the live input streams and/or pre-encoded media assets. The indexing and storage system 148 may log indicators indicating ad breaks, program start, program end, graphic overlays, and the like. The indexing and storage system 148 may further perform checks to validate that the live input streams and/or pre-encoded media assets are complete and ready for inclusion in the disparate live media output stream.
At 510, a plurality of corresponding disparate live media stream manifests may be generated based on the playout schedule 112 and content viewing demographics. In accordance with an embodiment, the stream publishing engine 150 may generate the plurality of disparate live media output streams and the plurality of corresponding disparate live media stream manifests. The stream publishing engine 150 may generate a disparate live media output stream manifest by inserting a new segment from the scheduled pre-encoded media asset manifest or the live input stream manifest into the disparate live media output stream manifest on an interval not greater than the previous content segment duration. In accordance with an embodiment, the plurality of disparate live media output stream manifests, referenced broadcast content segments, DRM licenses, and encryption keys may be delivered over a public or a plurality of private networks, such as the content delivery system 160. Each of the plurality of disparate live media output stream manifests may include a graphical treatment indicator for inserting graphical treatment content. Examples of the graphical treatment content may correspond to, but are not limited to, at least one of a promotional logo, an advertiser graphic, or an animation.
In this regard, the stream publishing engine 150 may generate disparate live media output stream manifest by manipulating the manifests of the pre-encoded media assets or the live input streams. Each of the plurality of disparate live media output stream manifests comprises an index of a plurality of pre-encoded media assets, a plurality of live input streams, and/or the non-programming content. Each of the disparate live media output stream manifests may further include one or more non-programming content indicators and/or one or more overlay indicators. In accordance with various embodiments, the plurality of disparate live media output streams may be generated for different geographical locations. Thus, the plurality of disparate live stream output manifests may be defined to support customized experiences for the first IP receiver 156 and the second IP receiver 158 in different audience segments and for receivers in different localization zones.
When the stream publishing engine 150 encounters indicators marking an ad break within the pre-encoded media asset manifest, the live input stream manifest, or the playout schedule 112, the stream publishing engine 150 may insert such indicators in the disparate live media output stream manifest. The stream publishing engine 150 may further stitch in ads and promotional content included in the playout schedule 112 and/or access the real-time linear ad server 152 to fill one or more portions of the ad break, as defined by the playout schedule 112.
In accordance with an embodiment, one or more non-programming content and one or more programming content included in the playout schedule 112 may be replaced with one or more alternate non-programming content and one or more alternate programming content. The one or more alternate non-programming content and the one or more alternate programming content may be selected based on the real-time or near-real-time content viewing demographics or content viewing data received from the media player. The stream publishing engine 150 may include one or more content replacement indicators that indicate replacement of one or more non-programming content and/or programming content. In an embodiment, the one or more content replacement indicators may cause replacement of one or more pre-encoded media assets of the plurality of pre-encoded media assets or one or more live input streams of the plurality of live input streams with one or more alternate pre-encoded media assets or one or more alternate live input streams. A use case is described herein for CNN, for example, where a local programming block is inserted in a particular country in partnership with a local broadcaster. In this case, a switch from the national schedule which could be pre-encoded assets or live international source may be performed to an alternate live local source stream. The one or more content replacement indicators may cause replacement of non-programming content and/or programming content. For example, the stream publishing engine 150 may signal one or more ads and promotional content for replacement and insert placeholder content to replace such ads and promotional content that were scheduled in the playout schedule 112 or decisioned in real-time. The stream publishing engine 150 may further signal one or more programing content blocks to be replaced with other programming content more desirable for the audience demographic, segment or location of a specific consumer device. The stream publishing engine 150 may further exclude one or more high quality profiles created for broadcast distribution from the consumer devices 110a, . . . , 110n. 
In accordance with an embodiment, as described above, the plurality of disparate live stream output manifests may be required to support different DRM types and consumer device categories and IP receiving system 155. In accordance with another embodiment, the plurality of disparate live stream output manifests may be generated for IP receivers, such as the first IP receiver 156 and the second IP receiver 158, located in different localization zones. Accordingly, the stream publishing engine 150 may mark one or more ads and promotional content for potential replacement. Such marked one or more ads and promotional content may be replaced with ads and promotional content for corresponding localization zone, if there are ads and promotional content that may maximize the revenue over the ad or promotional content placed in accordance with the playout schedule 112. Further, the stream publishing engine 150 may replace one or more programing content blocks with other programming content more desirable for corresponding localization zone. The stream publishing engine 150 may further exclude one or more low quality profiles from the IP receivers created for consumer devices 110a, . . . , 110n. 
In accordance with an embodiment, the stream publishing engine 150 may access the real-time linear ad server 152 to fill one or more portions of the ad break, as defined by the playout schedule 112. Thus, one or more ads and promotional content may be inserted in real-time as designated by the real-time linear ad server 152.
The real-time linear ad server 152 may leverage real-time audience data from one or more media players in set-top boxes and smart TVs that support ACR, or ATSC 3.0, Nielsen standards, and the like, to determine the current audience makeup. Accordingly, the real-time linear ad server 152 may select ads that may provide the maximum revenue yield based on real-time data. The real-time linear ad server 152 and/or the ad/promo campaign manager 114 may abide by traditional broadcast rules governing ad separation, ad exclusivity, ad positioning, and the like, for the individual ad pods and the overall program, when determining which ads provide the maximum revenue yield.
The real-time linear ad server 152 and/or the ad/promo campaign manager 114 has knowledge of localization zones, thus, may mark ads and promotional content where localized ads and promotional content may provide higher revenue yield. Therefore, the real-time linear ad server 152 and/or the ad/promo campaign manager 114 may perform decisioning ads and promotional content for specific locations to support a plurality of disparate live media output stream manifests for such individual geographic regions.
Further, the real-time linear ad server 152 and/or the ad/promo campaign manager 114 has knowledge of audience demographics and segments and may mark ads and promotional content targeted at specific audience demographics or segments. Accordingly, such ads and promotional content may be potentially replaced on consumer devices capable of individual targeting, if such consumer devices are not a part of that audience demographic or segment and the entire ad pod is not marked for replacement.
In accordance with an embodiment, the stream publishing engine 150 may transmit the output to the stream versioning engine 154 to create an appropriate variant of the disparate live media output stream manifest. The stream versioning engine 154 may receive versioning instructions from the switch logic manager 130. The switch logic manager 130 may define a number of disparate live media output stream manifests based on desired ad and content localizations, as well as ad rules for audience demographic and segment targeting. Such disparate live media stream manifest may be generated for the consumer device 110a based on its ability to support one-to-one targeted ad insertion.
In accordance with an embodiment, the stream versioning engine 154 may insert or pass through ad indicators for the consumer device 110a to replace the entire ad break with individual targeted ads and may stitch in placeholder content to replace the scheduled ads based on the instructions provided from the switch logic manager 130. In accordance with another embodiment, the stream versioning engine 154 may insert or pass through ad indicators to mark individual ads for potential replacement with targeted ads based on the user's location, known demographic information (such as females over 50 years), and known audience segments (for example auto intender for a luxury vehicle). In accordance with another embodiment, the stream versioning engine 154 may stitch in alternate programming content based on defined localizations or audience segment preferences. In accordance with another embodiment, the stream versioning engine 154 may exclude the one or more high quality profiles created for broadcast distribution from the consumer devices 110a, . . . , 110n. In accordance with an embodiment, the stream versioning engine 154 may be configured to generate versions of the plurality of live input stream manifests corresponding to the each of the live input streams to be published to various the IP receiving system 155.
At 512, at least one disparate live media output stream manifest of the plurality of disparate live media output stream manifests may be received. In an embodiment, the IP receiving system 155 of the stream playout and distribution system 104, such as the first IP receiver 156 or the second IP receiver 158, may be configured to receive at least one disparate live media output stream manifest of the plurality of disparate live media output stream manifests. In accordance with an embodiment, the IP receiving system 155, such as the first IP receiver 156 or the second IP receiver 158, may be configured to receive one or a plurality of the specified high-quality profiles that may be included in one or a plurality of disparate live stream manifest outputs targeted at the localization zone of the IP receiving system 155.
At 514, one or more broadcast content segments encoded in a first encoding format of the at least one disparate live media output stream manifest may be retrieved. In an embodiment, the IP receiving system 155 of the stream playout and distribution system 104, such as the first IP receiver 156 or the second IP receiver 158, may be configured to retrieve the one or more broadcast content segments encoded in the first encoding format of the at least one disparate live media output stream manifest. The IP receiving system 155 of the stream playout and distribution system 104, such as the first IP receiver 156 or the second IP receiver 158, may be configured to download the referenced one or more broadcast content segments from the content delivery system 160. Once downloaded, the IP receiving system 155 of the stream playout and distribution system 104 may decrypt and decode the one or more broadcast content segments.
At 516, the first encoding format of the one or more retrieved broadcast content segments may be converted to a second encoding format. In an embodiment, the IP receiving system 155 of the stream playout and distribution system 104, such as the first IP receiver 156 or the second IP receiver 158, may be configured to convert the first encoding format of the one or more retrieved broadcast content segments in the first encoding format to the second encoding format. The second encoding format includes an output from an analog interface, a modified resolution of the one or more broadcast content segments, or cropped the one or more broadcast content segments. The second encoding format may be compatible with traditional distribution techniques, as required by the location of an operator. In an example, the second encoding format may be uncompressed over an analog interface or may be in an uncompressed digital format over a serial digital interface (SDI). In another example, the second encoding format may be a re-encode of the decoded broadcast content segments using a CODEC that meets requirements of the operator of the receive location over an IP connection or Asynchronous Serial Interface. In another example, the second encoding format may be down conversion from a high definition video to a standard definition, as required by the operator of the receive location. In another example, the second encoding format may be a down conversion that may be produced by cropping or letterboxing the video as required by the stream owner operator and may be done as signaled on a per program ad or promotional content basis.
In accordance with an embodiment, the IP receiving system 155 of the stream playout and distribution system 104, such as the first IP receiver 156 or the second IP receiver 158, may be configured to parse through the disparate live media output stream manifest that may include the graphical treatment indicator. Accordingly, portions in the one or more broadcast content segments may be identified where graphical treatment content is to be rendered. Accordingly, the one or more broadcast content segments may be modified to include the graphical treatment content prior to converting the one or more broadcast content segments into the second encoding format. In accordance with an embodiment, the IP receiving system 155 of the stream playout and distribution system 11 may layer graphics on top of the decoded one or more broadcast content segments prior to the analog or uncompressed digital output or before the re-encode of the broadcast content. Such graphics may be signaled by indicators in the disparate live media output stream manifest or triggers embedded in the broadcast content segments. The graphics may be used to provide an experience equivalent to an experience provided on traditional broadcast channels. The graphics may include a network logo, an advertiser logo, a promotional logo, a banner type graphic, or a squeeze back of the disparate live media output stream with a promotional or advertiser graphic wrapping the disparate live media output stream. The graphic may further support motion, animations, and varying levels of transparency when overlaid on the disparate live media output stream.
During conversion, the IP receiving system 155 of the stream playout and distribution system 104 may be further configured to correct discrepancies during transaction between the plurality of pre-encoded media assets and/or the plurality live input streams and/or broadcast profiles. For example, the IP receiving system 155 of the stream playout and distribution system 104 may correct errors induced when switching between the pre-encoded media assets or live input streams. The IP receiving system 155 of the stream playout and distribution system 104 may further correct errors induced when switching between different video resolutions or encoding profiles.
In accordance with an embodiment, the IP receiving system 155 of the stream playout and distribution system 104 may be further configured to include a local storage. Accordingly, the IP receiving system 155 of the stream playout and distribution system 104 may be provided with advanced knowledge of pre-encoded media assets that may be included in one or a plurality of disparate live media output stream manifest. In such case, the broadcast content segments of the pre-encoded media assets may be pre-downloaded and stored in the IP receiving system 155 of the stream playout and distribution system 104. Accordingly, the requirement that an IP connection must always maintain necessary bandwidth to support the minimum specified live stream input bitrate or risk service interruptions may be eliminated. In accordance with an embodiment, live input streams may also be supported if live input stream are encoded locally or otherwise acquired in such a manner that did not rely on an IP connection that was not able to reliably support the minimum live stream input bitrate.
In accordance with an embodiment, the IP receiving system 155 of the stream playout and distribution system 104 may include a stream generation system with sufficient local storage and processors. In such an embodiment, the stream generation system may be configured to ingest the playout schedule 112 with all the ads specified ahead of time and index the manifests for the pre-encoded media assets included in the playout schedule 112. The stream generation system may be further configured to download the broadcast content segments, DRM licenses, and encryption keys, into local storage for the pre-encoded media assets included in the playout schedule 112. The stream generation system may be further configured to generate a disparate live media output stream manifest according to the playout schedule 112. The stream generation system may further comprise sufficient processors configured to receive the disparate live media output stream manifest, decrypt and decode the referenced broadcast content segments from the local storage, and process event indicators in the disparate live media output stream manifest or triggers embedded in the broadcast content segments. The stream generation system may be further configured to layer graphics on top of the decoded disparate live media output stream, and convert the stream back to a format, such as the second encoding format, compatible with traditional distribution techniques as required by the operator of the receive location. During conversion, the stream generation system may correct errors induced when switching between the pre-encoded media assets or live input streams. The stream generation system may further correct errors induced when switching between different video resolutions or encoding profiles. In such an embodiment, the stream generation system may eliminate the requirement that the IP connection must always be available or risk service interruptions.
In accordance with an embodiment, the IP receiving system 155 of the stream playout and distribution system 104 may serve as a proxy or cache to deliver the broadcast content segments to end consumer devices 110a, . . . , 110n. The IP receiving system 155 of the stream playout and distribution system 104 may further conserve Internet bandwidth to deliver content reliably to multiple users in a location that share a constrained Internet connection. In accordance with an embodiment, the IP receiving system 155 of the stream playout and distribution system 104 may be authorized to decrypt and store the decrypted broadcast content segments and disparate live media output stream manifests. The IP receiving system 155 of the stream playout and distribution system 104 may re-write one or a plurality of disparate live media output stream manifests to remove the DRM key references. The IP receiving system 155 of the stream playout and distribution system 104 may serve as a proxy or cache to deliver the rewritten manifests and decrypted broadcast content segments to end consumer devices 110a, . . . , 110n. The stream may be delivered over a secure local network to a plurality of consumer devices using 3rd party applications or mobile web sites that do not support DRM protected content.
In accordance with an embodiment, the IP receiving system 155 of the stream playout and distribution system 104 may be authorized to act as a token server to authorize consumer devices on a local network. The IP receiving system 155 of the stream playout and distribution system 104 may re-write one or a plurality of disparate live media output stream manifests to provide the local token server address to the IP receiving system 155. Further, the player configuration may be designed to use relative pathing to acquire an authorization token from the IP receiving system 155. In accordance with an embodiment, the IP receiving system 155 of the stream playout and distribution system 104 may deliver the stream in the first encoding format over a local network to the consumer devices 110b, . . . , 110n that support DRM. In such an embodiment, a central authorization service for consumer devices 110b, . . . , 110n on a local LAN sharing a common internet connection may be extremely difficult to manage as the number of receiver locations increase.
In accordance with an embodiment, the Ad decisioning server 106 may be configured to monitor a real-time and/or near real-time content viewing demographics based on data received from one or more media players in the consumer devices 110a, . . . , 110n. The Ad decisioning server 106 may be further configured to schedule the one or more pre-encoded media assets based on the real-time and/or near-real-time content viewing demographics.
FIG. 6 is a conceptual diagram illustrating an example of a hardware implementation for a web playout and distribution system employing a processing system for disparate live media output stream playout and broadcast distribution, in accordance with an exemplary embodiment of the disclosure.
Referring to FIG. 6, the hardware implementation shown by a representation 600 for the stream playout and distribution system 104 employs a processing system 602 for disparate live media output stream playout and broadcast distribution, in accordance with an exemplary embodiment of the disclosure, as described herein.
In some examples, the processing system 602 may comprise one or more hardware processor 604, a non-transitory computer-readable medium 606, a bus 608, a bus interface 610, and a transceiver 612.

In accordance with an embodiment, the processor 604 causes the stream playout and distribution system 104 in the media packaging and distribution system 102 to execute operations to generate a broadcast content schedule based on a plurality of broadcast content parameters associated with programming content scheduled for a broadcast channel.

The second encoding format is in accordance with one or more broadcasting protocols.
Given that the Internet has spawned rapid changes in how video is delivered, several solutions employing new internet protocols have been developed to replace the need for expensive transport, for example, satellite transport. These solutions are gaining popularity for channels with a limited number of receive locations, but such solutions do not address the high cost of the channel production itself or delivery to numerous receive locations. The solutions also fail to recognize that existing delivery protocols, such as HLS and DASH, are sufficient, in many cases, to produce and deliver channels at scale over a traditional content delivery network for a much lower cost.
Thus, the stream playout and distribution system 104 in the media packaging and distribution system 102 may be configured to manipulate the text-based pre-encoded media asset manifest and/or live input stream manifest to produce a new disparate live media output stream manifest. The disparate live media output stream manifest may be delivered to a contemporary receiver that supports modern web streaming protocols as the input and may provide a compatible legacy format as the output. The same live channels may also be delivered directly to Internet connected consumer devices eliminating need for parallel distribution processes. The only requirement is that to maintain broadcast quality through the IP receiving system transcode, the preparation for web distribution should include at least one additional high-quality version of the content.
Further, the broadcast content itself does not need to be processed beyond the initial creation of the live input streams and pre-encoded media assets prepared for web distribution. Thus, creation and distribution of new or variant channels become extremely inexpensive. The creation and distribution may be based solely on the cost to manipulate the manifests, which provide the instructions for the IP receiving systems or consumer devices to execute. The stream playout and distribution system 104 may also support targeted ad insertion at the IP receiving system 155 or individual consumer devices through the insertion of tags in the disparate live media output stream manifest. The stream playout and distribution system 104 may further leverage the processing power of the IP receiving systems and consumer devices to insert targeted channel graphics and overlay advertisements and promotions.
Further, in existing systems, audience for low cost and variant channels generated through manifest manipulation has been limited to the stream owner's digital customers on consumer devices. The development of the IP receiving system 155 in the stream playout and distribution system 104, that supports modern web protocols as the input and may convert the digital channel back to a more traditional format on the output, increases the available audience for these channels to include customers using third party apps and devices that require more traditional channel distribution methods.
Such receiver may further enable the cost of traditional broadcast channel production and distribution to be dramatically reduced. For channels consisting mostly of pre-produce content, the playout server, graphics system, and broadcast encoder may be replaced with simple manifest manipulation. Satellite distribution may be replaced with Internet delivery. Additionally, techniques common in digital streaming may increase the capabilities of the broadcast infrastructure, enabling near real-time Ad decisioning and channel versioning for regional advertising and content localization.
