## Background
CROSS REFERENCE TO RELATED PATENTS
This application is a continuation in part of U.S. application Ser. No. 11/535,347, filed Sep. 26, 2006, and entitled “METHOD AND SYSTEM FOR SELECTIVELY BROADCASTING MEDIA,” now U.S. Pat. No. 7,899,390, which is incorporated herein in its entirety by reference for all purposes.


FIELD
The present disclosure relates to a system and method for selectively providing content.
BACKGROUND
Many broadcast stations, such as radio broadcast stations, use computers running broadcast automation software, such as the NexGen DigitalTM radio broadcast automation software provided by Prophet Systems Innovation, to automate some, if not all, of an entire broadcast. Broadcast content typically includes various media events such as songs, movies, advertisements, jingles, news spots, traffic, radio host commentary, interviews, station identification, segues, beds, promos, station identification, time and temperature, voice tracks and the like.
Generally, broadcast content is stored electronically in individual files, and is compiled into a broadcast program log or playlist that may include a chronological arrangement of various types of broadcast content to create the desired listening “experience.” For example, a playlist for a radio music program may include a series of songs with station identification and advertisements interspersed at various intervals.
Many broadcast stations are part of larger broadcast systems or networks that allow broadcast programs to be shared. For example, one broadcast station may host a live program, record that program, and transmit that program to another broadcast station for rebroadcast.
When networked broadcast stations share programming, content broadcast transmitted from one broadcast station may not be appropriate for another broadcast station. For example, a broadcast program may include songs, movies and/or advertisements pertinent to a particular audience and not to another audience. Or, a program from one broadcast station may be transmitted to multiple broadcast stations having diverse audiences, such as paid subscribers to an Internet-based broadcast, or to HD radio listeners, and certain content may be undesirable for that audience. There is a need, therefore, for a method and apparatus of selectively providing content.
SUMMARY
Methods and systems for selectively broadcasting media events are disclosed herein.
In various embodiments disclosed herein, a daypart of an event log is configured for spot-free broadcast by identifying a plurality of spots in the daypart of the event log, skipping the spots, and broadcasting only the content media events in the event log. The spot-free daypart broadcast may be offered for subscription, or as an introductory inducement for users to listen to a broadcast. The event log, prior to being used in the embodiments, includes a sequence of both spots and content media events. The embodiments can also include receiving user input in near-real-time and inserting the preferred content media event into the event log in near-real-time. The preferred content media event can be smart-aware. After skipping or inserting media events in the event log, the step of broadcasting media events can include stretching at least one of the content media events. Furthermore, a list of content media events broadcast during the spot-free daypart can be generated, and content media events can be skipped based on elements of their feature status, which can include having been previously broadcast in the same daypart, as indicated by a mark.
In other embodiments, a daypart of an event log is configured for sponsored-by broadcasting by identifying a plurality of spots in the daypart of the event log, skipping the spots, and broadcasting only the content media events in the event log. In addition to the elements of the above-discussed spot-free daypart embodiment, the sponsored-by embodiments can include inserting sponsor identification media events into the event log and broadcasting only the content media events and sponsor identification media events in the event log.
In other embodiments, a server is configured to identify a daypart of an event log to be configured for spot-free broadcast; identify, in the daypart of the event log, a plurality of spots; skip the spots; and broadcast only the content media events in the event log. The server can be configured to receive user input in near-real-time, via a process such as a web service, indicating at least one preferred content media event; insert the preferred content media event into the event log in near-real-time; and stretch at least one of the content media events in the event log. Furthermore, the server can be configured to generate a list of content media events broadcast during the spot-free daypart and skip content media events based on elements of their feature status, which can include having been previously broadcast in the same daypart, as indicated by a mark.

DETAILED DESCRIPTION
The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.
A detailed description is provided primarily in the context of radio broadcasting, but those skilled in the art will appreciate that the invention is not limited to radio broadcast operations. As seen in the embodiment of FIG. 1, a broadcast station X may include a primary workstation 1 using broadcast automation software to automate broadcast operations. The primary workstation 1 may be connected to a primary file server 2 and a primary audio server 3. Another broadcast station Y may include a secondary workstation 5 also using broadcast automation software to automate broadcast operations. The secondary workstation 5 may be connected to a secondary file server 7 and a secondary audio server 6. In this embodiment, the primary audio server 3 and secondary audio server 6 are connected to antennas 4 & 8, respectively. In this embodiment, the primary audio server 3 is connected to the secondary audio server 6 through a network 9, such as the Internet or wide area network. Such connection may, of course, be direct or indirect, electrical and/or physical, and may be wired or wireless. Those skilled in the art will recognize that the primary workstation 1 and secondary workstation 5, along with their respective file servers 2 & 7 and audio servers 3 & 6, may be co-located at a broadcast station or located apart, and may, for example, serve different radio audiences.
In this embodiment, the primary and secondary workstations 1 & 5 each use NexGen DigitalTM v.2.4.19.1 broadcast automation software. The primary file server 2 and primary audio server 3 connected to the primary workstation 1 may, for example, be mounted in a common rack and connected to other hardware that may be used for broadcast station operation, such as to an audio switcher, a universal power supply, digital reel-to-reel hardware, real-time editor hardware, mixing boards and the like. A similar arrangement may be provided for the secondary workstation 5, secondary file server 7 and secondary audio server 6. Those skilled in the art will recognize that the environment illustrated in FIG. 1 and described herein is not intended to limit the present invention. Indeed, those skilled in the art will recognize that other alternative hardware and environments may be used without departing from the scope of the present invention. A server computer may, for example, include a processor, a random access memory, data storage devices (e.g. hard, floppy, and/or CD-ROM disk, drives, etc.), data communications devices (e.g., modems, network interfaces, etc.), display devices, (e.g., CRT display, LCD display, etc.), and input devices (e.g., mouse pointing devices, keyboard, CD-ROM drive, etc.). A server may, for example, be attached to other devices, such as a read-only memory, a video card, a bus interface, a printer, etc. Those skilled in the art will appreciate that any combination of the above components, or any number of different combinations, peripherals, and other devices, may be used with the server. Likewise, those skilled in the art will recognize that various servers, workstations, hardware and software described herein, whether termed “file server,” “audio server,” “workstation,” “first server,” “second server,” “switcher,” “editor,” “storage device,” “broadcast automation software,” “buffer,” “adapter,” “broadcast station” and the like, and the capabilities and features ascribed thereto, may refer to different functions, programs and/or applications of one or more computing devices in a single location or spread over multiple locations, and may be implemented in hardware, software, virtualized hardware, cloud-based processing, or some combination of the two.
In this embodiment, the primary and secondary file servers 2 & 7 may be used to store various media events, and the primary and secondary audio servers 3 & 6 may be used to mix and play media events, for example, over the air or over the Internet as a radio broadcast. Accordingly, the primary and secondary audio servers 3 & 6 may each be provided with a multi stream PCI audio adapter (not shown) designed for broadcast use and having, for example, one “record” stream input and six “play” stream outputs. Such an adapter may be any suitable adapter, and may, for example, be the model ASI6122 audio adapter from Audioscience.
A user at the primary workstation 1 may create a radio broadcast program by using the broadcast automation software to arrange audio content into a log of media events. As seen in the embodiment of FIG. 2, the exemplary broadcast automation software allows a broadcast station to automate the production of a radio program through creation of a media event log 11, from which a playlist may be generated. As used herein, the terms “log” and “playlist” may be used interchangeably. As used in the claims, the term “automation playlist” includes both “log” and “playlist,” and a generally connotes a sequence of media events. In the event log interface 10, a broadcaster may define, over a 24-hour period, when and how various media events will be played in order to create the radio broadcast “experience,” as is known to those skilled in the art. The media event log 11 may thus generally be a time-based collection of media events arranged in playback order, and may include metadata associated with the media events, such as song title, artist, radio station identification, macros (user-defined sequences of media events) and the like. Generally, a media event log may cover a day's worth of programming, but other time periods may be used, as well, and the event log 11 may be planned and created well in advance of actual broadcast. The event log 11 may, for example, indicate to the broadcaster whether airtime has been adequately filled, and describe the type of media events to fill various day parts.
In the embodiment of FIG. 2, the media event log 11 provides a list of media events arranged according to the time during which each media event will play. In this embodiment, the event log 11 sets out an exemplary morning show radio program that includes advertisement spots and songs. For example, a one-minute long “Great High Mountain Tour” advertisement spot 12 is shown as scheduled to play at 9:18:09, followed by the “Miss Independent” song 13 by artist Kelly Clarkson, which is shown as scheduled to play at 9:19:09. Also, for example, an “animal encounter” advertisement spot 14 is scheduled to begin play at 9:22:38, and end at 9:22:54.
As is known in the art, the relationship between the media events may be defined to enhance the radio broadcast “experience.” The various transitions between media events may include, for example, crossfades, overlap, clipping, ducking, and fade in and fade out. In the audio context, for example, “fading” generally refers to the process of changing the volume of a media event over time. “Fade in” and “fade out” thus generally refer to increasing and decreasing, respectively, the volume of a media event over time, and “cross fading” generally refers to simultaneously fading out the end of one media event, while fading in the beginning of the next media event. “Fading” is commonly done at the beginning and end of a media event, but may be accomplished during other portions of a media event, as well. “Clipping” generally refers to the process of excluding a portion of a media event during playback, such as the beginning or end of a song or video element. “Ducking” generally refers to reducing the volume level of background audio while another media event, such as a voice track, is playing. “Overlap” generally refers to simultaneous performance of media events.
So defined and arranged, the media events of such a log, or playlist, may be played in real-time as, for example, an on-air broadcast to provide the radio broadcast “experience.” With reference to FIG. 1, the broadcast automation software running on the primary workstation 1 directs retrieval of the media events listed in the playlist from the primary file server 2, and directs the primary audio server 3 to mix and play the media events as they appear in the media event log or playlist. The primary audio server 3 may play the media events for broadcast via antenna 4. Those skilled in the art will recognize that broadcast could easily be over the Internet or some other network. Those skilled in the art will appreciate that the term “broadcast” includes transmission of media from one to many, e.g., from a broadcast station or network of broadcast stations to a consuming audience, by any transmission medium.
In this embodiment, the secondary audio server 6 may be configured to function as a slave to the primary audio server. Multiple secondary audio servers can be configured to function as slaves to a single primary audio server. With reference to FIGS. 1 and 3, a user at the secondary workstation 5 may establish the relationship 21 between the secondary audio server (represented by the “Commercial-less Audio Server” in the list of stations) and primary audio server (represented by the “scottbr2” station) through a user interface 20 that may be provided by the broadcast automation software running on the secondary workstation 5. Thus, in addition to broadcasting the media events via antenna 4, the primary audio server 3 may also play the media events directly to the secondary audio server 6. Such play may be in real-time. Specifically, the primary audio server 3 may play through an output of its audio adapter the media events into the input of the secondary audio server's audio adapter. The secondary audio server 6 store the media stream in a buffer until directed by the secondary workstation to start playing the buffered media as, for example, an over-the-air broadcast via antenna 8. Those skilled in the art will appreciate that the buffer may be any suitable computer-readable medium.
In this embodiment, when playing media events from the secondary audio server 6 buffer, various undesired media events may be skipped. For example, it may be desired to play a rotation in which all of the advertisements are skipped. As seen in the embodiment of FIG. 4, the broadcast automation software running on the secondary workstation may accordingly provide a user interface 30 to permit that rotation 31 to be specified.
With reference to the embodiment of FIG. 5, the primary audio server 3 may play a sequence 50 of media events A, B, C, D, . . . in real time into the buffer 51 of the secondary audio server 6 (the file servers 2 and 7 of FIG. 1 are not shown here). That is, the sequence 50 of media events may be streamed from the primary audio server 3 to the buffer 51, and after a portion of that sequence 50 has been stored in the buffer 51, the sequence 50 of media events may be broadcast from antenna 8 at broadcast time t1 from the secondary audio server 6 on a first-in first-out basis. Generally, amount of buffer B1 . . . B6 may be specified to be a certain duration of real-time media event play. Use of the buffer 51 allows the playlist of media events to be altered prior to broadcasting, as discussed in further detail below.
In one embodiment, the primary audio server 3 and the secondary audio server 6 may be scheduled to begin broadcasting the same play list of media events at the same time. The primary audio server 3 may, for example, broadcast the playlist of media events to one audience, and the secondary audio server 6 may broadcast an advertisement-free version of that playlist to another audience. The primary audio server 3 may begin streaming 60 the media events, in playlist sequence, into the buffer 51, as seen with reference to FIG. 6. If, for example, a buffer of six minutes B1 . . . B6 is desired, the primary audio server 3 may begin playing the stream 60 of media events A, B, C, . . . into the buffer six minutes (at time t1) before the scheduled broadcast time t7. Thus, at the broadcast time t7, the buffer 51 will contain six minutes-worth of audio.
Turning to FIG. 7, broadcast of stream 61 of media events from the primary audio server 3 and broadcast of stream 62 from the secondary audio server 6 may be scheduled to begin at time t7. In FIG. 7, broadcast has begun and has continued through time t10. During that time, the primary audio server 3 may continue to play the stream 60 of media events into the buffer 51. As noted above, the primary audio server 3 may be provided with an audio adapter that allows multiple output streams 60 & 61.
In this embodiment, the user has configured the broadcast automation software of the secondary workstation 5 to instruct the audio server 6 to identify and not play advertisement spots. In the embodiment of FIG. 2, for example, spots to be skipped may be marked by the primary audio server with special markers that are displayed in the media event log 11 as “spot blocks,” as with the animal encounter spot 14. According to that embodiment, the secondary audio server 6 may then detect those spot blocks and skip the spot or spots marked by the spot blocks.
In the embodiment of FIG. 7, spot C may be an advertisement spot. Spot C may be desired in the media event stream 61 from the primary audio server 3, but undesired in the media event stream 62 from the secondary audio server 6. Accordingly, spot C may be identified and not played from the buffer, and the secondary workstation's 5 broadcast automation software may instruct the secondary audio server 6 to play media event D immediately after playing media event B. Removal of spot C from the rotation, however, shortens the scheduled play list by some amount of time, i.e., the buffer amount is “used up” by skipping media events. To fill that airtime gap, the broadcast automation software may instruct the audio server 6 to slow down (stretch out) playback of one or more, or all, subsequent spots. In this embodiment, the user may configure the broadcast automation software to instruct the secondary audio server 6 to immediately play media event D after media event B and stretch, i.e., slow down, the subsequent media events D, E, F, . . . . As seen in FIG. 4, for example, the user has specified a stretch percentage 32 of 4%, and in this embodiment may stretch playback by up to 20%. Stretching subsequent songs by 4%, for example, may fill an additional 2.4 minutes of airtime per hour. In this embodiment, such stretching may be accomplished, as is known in the art, without altering the pitch of subsequent spots to avoid, for example, “draggy turntable” voices. Those skilled in the art will appreciate that other stretching and/or squeezing ratios may be applied. Alternatively, the broadcast automation software may be configured to instruct the audio server 6 to stretch out playback of only certain spots, for example, only media events D and E, as may be needed to fill airtime gap left by removal of spot C. In this embodiment, such stretching may be utilized for as long as may be needed to re-fill the buffer 51 to a minimum amount of media event play time. That is, media events in the media stream 62 may be played out from the buffer 51 more slowly than the media events of the stream 60 are played from the primary audio server 3 into the buffer 51, and the difference in play rate results in re-filling the buffer 51.
Referring generally to the embodiment of FIG. 7, for example, it may be that media events A and B are songs, media event C is an advertisement spot, and media events D, E and F are songs (the remaining media events may be, in this example, of various types). In this example, each media event may be one minute long. Playback of songs A . . . F will require 6 minutes of airtime. If broadcast is scheduled to begin from the primary audio server 3 and from the secondary audio server 6 at the top of the 9 a.m. hour (09:00:00), and a buffer of six minutes is required, the primary audio server 3 may begin playing the stream 1 of media events into the buffer 51 at 08:54:00, as described above in connection with the embodiment of FIG. 6. Thus, at broadcast time 09:00:00 (t7), media events A . . . F will be stored in the buffer 51 and ready for broadcast. In this embodiment, therefore, both the primary audio server 3 and the secondary audio server 6 will begin their broadcast at 09:00:00 with song A and followed by song B. Immediately after song B finishes playing, the primary audio server 3 will begin playing advertisement spot C. The secondary audio server will, however, remove advertisement C from the playlist rotation (as shown by the dash-marked “times lot” C), and begin playing song D immediately after playing song B. Removal of advertisement C shortens that airtime play of media events A . . . F from the secondary audio server by one minute. To fill that airtime gap, and “catch up” to the broadcast 61 from the primary audio server 3, the secondary audio server 6 may stretch songs D, E and F to fill that space, so that the broadcast 62 from the secondary audio server 6 is substantially synchronous with the broadcast 61 from the primary audio server 3 by the time song F begins to play at 09:06:00. As noted above, of course, such stretching may be spread out over fewer or additional subsequent spots or all subsequent spots. Those skilled in the art will recognize that such stretching may, for example, be delayed until later in the playlist, or may be limited to song D. Generally, immediately playing song D after song B with or without stretching out one or more subsequent spots may draw down the amount of media event playtime stored in the buffer.
Those skilled in the art will also recognize that stretching may not be used at all. In the embodiment of FIG. 8, spot C may be removed and songs D, E, F . . . may be played immediately after song B without stretching, and the buffer amount may be accordingly reduced to five minutes of airtime (B1 . . . B5). The bracketed media event designations [C], [D] and [E] in the units marked by dashed lines illustrate the sequence of media events that would exist without removal of spot C.
Accordingly, an appropriate buffer may be established and maintained at a level sufficient to provide a reserve of media events to fill airtime gaps. For example, a minimum buffer size of five minutes may be sufficient to cover typical advertisement spots if stretching is used. F or longer station breaks, such as for news, a longer buffer may be required, and may range, for example, between 7.5 minutes and 14 minutes. In the embodiment of FIG. 4, for example, the minimum buffer size 33 is set at five minutes.
Also, the broadcast 62 from the secondary audio server 6 may be supplemented from a secondary playlist. A user at the secondary workstation 6 may create a secondary log or playlist of media events suitable for the intended audience of the secondary broadcast station. The secondary log or play list may be created using the automation broadcast software to, for example, create a clock with empty song slots, define a music load format for the station (such as “R&B”), based on the music load format generate a log of music similar to the media event log 11 of FIG. 2, and load the music from the secondary file server 7 to the secondary audio server 6. Those skilled in the art will appreciate that the secondary play list may comprise a single type of media events or may comprise a variety of types of media events, such as songs, news and advertisements pertinent to the secondary station's broadcast audience, station identification, radio personality commentary and the like.
In one embodiment, with reference to FIG. 9, the primary audio server 3 may begin broadcasting the primary playlist at 09:00:00 (time t7) while simultaneously playing the primary playlist to the buffer 51 of the secondary audio server 6. The secondary audio server 6 may broadcast from a secondary playlist 63 of spots α, β, γ, δ, ε, . . . at 09:00:00 while an adequate reserve B1 . . . B6 of the media events, from the primary audio server 3 is being stored in the buffer 51, and then switch over to broadcast of the buffered primary playlist when the buffer requirements B1 . . . B6 are met. Thereafter, the secondary audio server 6 may remove undesired media events as described above.
In the embodiment of FIG. 10, the secondary audio server 6 may refill the buffer with one or more media events from the secondary playlist 63, thus drawing media events from the secondary file server 7. For example, song a may be added to the buffer, and, if necessary, stretched (or squeezed) to fill the airtime that would have been filled by advertisement C. Alternatively, songs α and β (or other media events from play list 63) may both be added to the buffer (not shown), and squeezed to fill the airtime. Those skilled in the art will recognize that songs D, E, . . . may also be squeezed or stretched as may be appropriate to accommodate media events from the secondary play list 63, and that additional buffered media events may be removed from or used to fill the airtime as the case may be if, for example, such squeezing and/or stretching of songs D, E, . . . is inappropriate. Additionally, those skilled in the art will recognize that media events from the secondary play list 63 may be added to the buffer to supplement any part of the broadcast 62, including supplementation immediately after song B.
Also, if during broadcast the amount of buffered media becomes inadequate to meet airtime fill requirements, the secondary playlist 63 may be played until the buffer requirements are once again met. F or example, if the buffer has less than 15 seconds of media event play time stored, the secondary playlist 63 may be played until some threshold buffer requirement is met. Alternatively, if the primary playlist 61 is exhausted, the secondary audio server 6 may switch back to broadcasting the secondary playlist 63.
If the secondary playlist 63 is also exhausted, the secondary audio server 6 may play filler material established as appropriate for that station. In the embodiment of FIG. 11, for example, the broadcast automation software may allow a user to create a category of songs that may be used to fill gaps in airtime. The user may do so by accessing the configuration menu 70 of the exemplary broadcast automation software installed on the secondary workstation 5, and selecting the “station” option to bring up an interactive dialog box 71 that allows the user to change the fill category 72. The category of fill media events selected may be valid for that station, e.g., “R&B” filler material for an “R&B” station format. Those skilled in the art will appreciate that a secondary play list is not required, and that random filler material may just as easily be used.
Those skilled in the art will recognize that the transition between media events of the secondary playlist and media events of the primary playlist may be defined in a manner noted above. For example, the last media event played from the secondary playlist may cross fade into the first media event played from the primary playlist. In the embodiment of FIG. 4, for example, a user may establish the rotation 34 to play immediately before transitioning from the primary play list to the secondary playlist, and may establish the rotation 35 to play in transitioning from the secondary playlist to the primary playlist. In the embodiment of FIG. 4, the user has established “intros” to segue into a media event from the secondary play list and “outros” to segue out of that media event.
In one embodiment, the broadcast automation software installed on the secondary workstation may provide an indication to the user of the status of the secondary audio server's buffer, such as how full the buffer is, which portion of the primary playlist is stored in the buffer, the types of media events stored in the buffer and the like. The broadcast automation software may also allow a user to “jump ahead” in the buffer to, for example, skip portions of the playlist. The broadcast automation software may allow a user to rearrange the portions of the play list stored in the buffer. Thus, the play list does not necessarily have to be played from the buffer on a first-in first-out basis. Additionally, the broadcast automation software may allow a user to “dump” buffered media events into a media events log of the secondary station, and update the playback times in that media events log based on the buffer information. Furthermore, those skilled in the art will recognize that the secondary audio server 6 may output more than one stream from buffer 51, and may separately manipulate those streams as discussed herein. For example, one stream may be entirely advertisement free, and another stream may have advertisements inserted from a secondary play list.
As is shown in FIG. 12, the primary audio server 3 and the secondary audio server 6 may be scheduled to begin broadcasting the same sequence of media events at the same time. The primary audio server 3 may, for example, broadcast the sequence of media events to one audience, and the secondary audio server 6 may broadcast a spot-free version of that playlist to another audience. The broadcast of a spot-free version of the playlist may be offered for subscription, or as an introductory inducement for users to listen to a broadcast. The primary audio server 3 may begin streaming 1200 the media events, in sequence, into the buffer 1202, as seen with reference to FIG. 6. Broadcast of stream 1201 of media events from the primary audio server 3 and broadcast of stream 1204 from the secondary audio server 6 may be scheduled to begin at time t7. In FIG. 12, broadcast has begun and has continued through time t10. During that time, the primary audio server 3 may continue to play the stream 1200 of media events into the buffer 1202. In addition, all times are partitioned within dayparts. Dayparts are divisions, based upon audience composition, of a 24-hour day of broadcasting; this is done for the purpose of scheduling what type of media events will be broadcast during a given time of day. For example, a 24-hour day may include, but is not limited to dayparts for early morning, daytime, lunch time, rush hour, and prime time broadcasts. In FIG. 12, Daypart 1 extends from t10 through t8, and Daypart 2 begins at t7 and extends through t1.
The user has configured the broadcast automation software of the secondary workstation 5 to instruct the audio server 6 to configure broadcasts during Daypart 2 to be spot-free broadcasts. In FIG. 12, for example, spots are identified by the audio server 6, and are skipped on the output stream 1204, leaving the output stream 1204 to include content media events. Content can include, but is not limited to radio programs, songs, traffic and weather reports. Spots to be skipped may be marked by the primary audio server with special markers that are displayed in the media event log 11 as “spot blocks,” as with the animal encounter spot 14. According to that embodiment, the secondary audio server 6 may then detect those spot blocks and skip the spot or spots marked by the spot blocks. Points in the output stream 1204 may also be marked with special markers displayed in the media event long as “substitution markers.” These substitution markers would indicate that a marked media event is to be skipped, and a media event, such as a spot, is to be inserted in place of the marked media event.
In the embodiments of FIG. 12, content media events broadcast during the spot-free daypart, such as Daypart 2, can be marked 1208 so that the secondary audio server 6 can generate a list of the content media events that have been broadcast during the spot-free daypart. Such a list can include information about the content media events, including, but not limited to title, artist(s), and when the content media event was played or broadcast. This list can be used to identify if a content media event in the event log has been previously broadcast in the same daypart. A secondary audio server 6 or secondary file server 7 can be configured to use the list to skip content media events if a feature status of the content media events meet predetermined criteria. For example, if a server determines from the feature status of a content media event, or a generated list of broadcasted content media events, that the content media event has been broadcast at least once during a daypart, the server may skip subsequent iterations of the same content media event in the event log.
The secondary audio server 6 may refill the buffer with one or more preferred content media events from a secondary playlist 1206, thus drawing media events from the secondary file server 7. For example, song A may be added to the buffer, and, if necessary, stretched (or squeezed) to fill the airtime that would have been filled by spot α. Alternatively, songs A and  (or other media events from play list 1206) may both be added to the buffer (not shown), and squeezed to fill the airtime.
The playlist 1206 is populated with content media events that can be determined by input from a user. The user can be a content provider, such as an internet radio station or web page, or a consumer or consumer device. User input can be received in real-time as the event log is being broadcast; input can be received in near-real-time through the use of a web service, or any similar system or process. Upon receiving user input as to the desired content media events that are to populate the playlist 1206, the playlist 1206 can be filled and arranged according to any pattern. For example, the content media events in the playlist 1206 can be arranged in order of increasing or decreasing popularity, as can be determined from frequency of appearance in user input. Alternatively, the content media events can be arranged in a random order.
The user-preferred content media events in playlist 1206 can be inserted into the event log in near-real-time, through the use of a web service or any similar system or process, through the buffer 1202, according to any pattern. For example, the user-preferred content media events can be inserted into the event log at random or pre-determined intervals. Alternatively, the user-preferred content media events can be inserted directly before or after spots that are skipped in the output stream 1204.
The content media events inserted from playlist 1206 can also be smart-aware content media events. A smart-aware content media event can receive information associated with media events preceding and following the smart-aware content media event in the event log. Upon receiving this information, the smart-aware content media event can provide input to the secondary file server 7 with regard as to both which content media events should populate the secondary playlist 1206 and when content media events are to be inserted into the event log for stream 1204.
The user can also configure the broadcast automation software of the secondary workstation 5 to instruct the audio server 6 to configure broadcasts during Daypart 2 to be sponsored-by broadcasts. Like the above embodiments, the secondary audio server can be configured to skip spots detected in the event log for stream 1204. In addition, playlist 1206 can be populated with sponsor identification media events that identify the sponsor of the sponsored-by broadcast. The secondary file server can be configured to insert sponsor identification media events at random, predetermined, or no intervals.
In FIG. 13, the process 1300 of configuring an event log for spot-free broadcast during a daypart is illustrated and discussed. As shown in block 1302, the daypart that is to contain the spot-free broadcast is identified in the event log for the output stream. As shown in block 1304, spots in the portion of the event log for the output stream that falls within the relevant daypart are identified. As shown in block 1306, the spots in the portion of the event log for the output stream that falls within the relevant daypart are skipped. Such skipping can be through configuring the secondary audio server 6 to skip over the relevant spots during broadcast; skipping can also be accomplished through the removal of the relevant spots from the event log for the output stream. As shown in block 1307, content media events broadcast during the daypart can be marked. Such marks can be used to generate a list of media events broadcast during the daypart, as shown in block 1308. As shown in blocks 1309-1318, the feature status of each content media event in the relevant daypart of the event log for the output stream can be checked. As shown in blocks 1310-1314, if the content media event is already present in the relevant daypart of the event log for the output stream, the content media event can be skipped. As shown in block 1320, user input that indicates preferred content media events can be received. As shown in block 1322, input from smart-aware content media events that indicates preferred content media events can be received. As shown in block 1324, preferred content media events can be inserted into the event log for the output stream. As shown in block 1328, content media events, including content media events originally in the event log for the output stream and those inserted, can be stretched or squeezed to accommodate insertions of content media events into the event log. As shown in block 1330, the content media events in the event log for the output stream are broadcasted.
While the invention has been described with reference to the foregoing embodiments, other modifications will become apparent to those skilled in the art by study of the specification and drawings. For example, the foregoing description may apply in a television, video, and text broadcast context, where the automation playlist may comprise media events of audio and/or visual nature, and the broadcast equipment involve, for example, television broadcasting equipment. Also, the automation play list need not be generated by broadcast automation software, and may simply be an arrangement of media events generated by known music mixing software, such as Adobe Audition. It is thus intended that the following appended claims define the invention and include such modifications as fall within the spirit and scope of the invention.
Various embodiments involving configuring a media stream for spot-free or sponsored-by broadcast have been discussed. Other variations and modifications of the embodiments disclosed may be made based on the description provided, without departing from the scope of the invention as set forth in the following claims.
