## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of U.S. patent application Ser. No. 11/948,824 filed Nov. 30, 2007, the disclosure of which is incorporated by reference herein in its entirety. The co-pending application is assigned to the same assignee as this application, AT&T Delaware Intellectual Property, Inc. of Wilmington, Del.


BACKGROUND
Exemplary embodiments generally relate to telecommunications, and more particularly, to systems, methods, and computer products for providing podcasts via Internet Protocol Television.
Internet Protocol Television (IPTV) is a digital television delivery service wherein a digital television signal is delivered to subscribers (and users of subscribers' devices) via a computer network infrastructure using the Internet Protocol. Typically, IPTV services are bundled with additional Internet services, such as Internet web access and voice over Internet protocol (VOIP). Subscribers may receive IPTV services via a computing device, such as a set-top box, that is connected to a television or display device for the reception of an audio/video signal. Used in conjunction with an IP-based platform, the set-top box allows for the subscribers to access IPTV based services and additional services that are integrated within the IPTV platform.
IPTV service platforms allow for an increase in the interactive services that may be provided to the subscribers. As such, the subscribers may have access to a wide variety of content that is available via the IPTV service or the Internet. For example, a subscriber may utilize interactive services via a set-top box to view IPTV content or access personal electronic messaging accounts via an Internet web browser. The IPTV infrastructure may also allow the delivery of a variety of audio/video content instantly to the subscriber.
In conventional cable and satellite based television delivery systems, the subscriber is limited to receiving audio/video content either by pre-determined programming content, such as network television, and/or cable stations, such as HBO®. Subscribers may also receive music and/or audio content through dedicated “music channels” and/or “news channels”. However, a subscriber may wish to receive content independent of available dedicated channels. An example of such content includes podcasts. Podcasts may be digital media files containing content decipherable by a computer device. In conventional cable and satellite based television delivery systems, there are no solutions for providing individual digital media files to subscribers.

Turning to FIG. 1, a block diagram of an exemplary podcast providing system 100 is illustrated. For ease of illustration, the system 100 of FIG. 1 depicts a simplified network infrastructure. In addition, for ease of illustration, the system 100 is described as implementing an Internet Protocol Television (IPTV) system for reception of programming, scheduling, and IPTV-based services. It is understood that the systems and methods described herein may implement television and program-viewing systems other than IPTV. For example, the system 100 may implement cable, satellite, antenna, etc.
Furthermore, it is understood that a variety of network components/nodes may be utilized in implementing the embodiments described herein. For example, in exemplary embodiments, the system 100 includes a means for accessing network services for multiple disparate devices using a single sign-on procedure. The means for accessing network services may include one or more IPTV infrastructure(s) 140, IPTV gateways 145, and/or other suitable components/nodes. Therefore, the system 100 manages accounts, each of which may be established for a community of devices and/or device subscribers, such as those devices and subscribers at a subscriber location 105, which may include a communications device 110 (e.g., a display device or television) operatively connected to a computing device 111, such as a set top box. Where the communications device 110 is a television, the set-top box 111 may include a processor that provides bi-directional communications between the IPTV infrastructure 140 and the communications device 110 and decodes the streaming media received as content programming and onscreen programming information, from a content services provider system 160, discussed further below. Other services may be provided to the subscriber location 105, such as, but not limited to, phone services, network services and other services such as providing podcasts that may be received at the communications device 110. The accounts may thus include phone, network access, and IPTV services, and may be used to provide access to podcasts as described further herein. Furthermore, in exemplary embodiments, one of the devices (e.g., the communications device 110) may be provisioned for the network services described herein by associating a device identifier of the communications device 110 with a respective account. The account, in turn, identifies each of the communications devices belonging to the community and provides other information as described herein. Furthermore, it is appreciated that other devices, such as a subscriber computer 125, may be further included in the community of devices established for the subscriber location 105. It is appreciated that the subscriber computer 125 may be local to the subscriber location 105 or may represent any other computer that may be used to access the services described herein. It is further appreciated that other remote devices may be implemented to access the services described herein such as but not limited to a cellular telephone (e.g., a 3G cell phone), a personal computer, a laptop computer, a portable computing device (e.g., personal digital assistant), a digital music player (e.g., MP3 player), etc.
In exemplary embodiments, one of the devices, such as the communications device 110 (or the communication device 110 and set-top box 111 combination) may be used to establish account services, such as receipt of podcasts. An account record may be generated for the subscriber at the subscriber location 105, which identifies the subscriber and the account for which the services (e.g., basic account services as described above) may be billed to and/or for which invoice or account summaries may be transmitted to. Account information and records may be stored in a storage device accessible by the IPTV gateway 145, discussed below. In exemplary embodiments, the IPTV gateway 145 implements one or more applications for establishing and utilizing access to the account. Access to the account may thus be created for a community of communications devices (e.g., the communications device 110) to enable the communications devices to receive podcasts as described herein. A preferences server 150, which is coupled to the IPTV gateway 145, includes preferences information for the subscriber location 105 as described further herein.
As discussed above, the system 100 of FIG. 1 includes the subscriber location 105, such as the subscriber's household. The subscriber location 105 may include the communications device 110 (e.g., an IPTV-enabled television) in communication with the set-top box 111. The subscriber location 105 may further include a personal digital recorder, such as a digital video recorder (DVR) 112, which is in communication with the communication device 110 and the set-top box 111. It is understood that the set-top box 111 and the DVR 112 may be two separate devices or be a single integrated device 114. In exemplary embodiments, the DVR 112 may be hard-disk based, but may alternatively have other suitable storage media such as a cache or solid-state memory, or have a hard-disk and other storage medium combination. It is appreciated that the DVR 112 may have other suitable memory devices for receiving and storing programming and scheduling data. Therefore, a “memory” or “recording medium” may be any means that contains, stores, communicates, propagates, or transports the program and/or data for use by or in conjunction with an instruction execution system, apparatus or device. Memory and recording medium may be, but are not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus or device. Memory and recording mediums also include, but are not limited to, for example, the following: a portable computer diskette, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), and a portable compact disk read-only memory or another suitable medium upon which a program and/or data may be stored.
The subscriber location 105 may further include a remote control 115 for control and navigation of the communications device 110, which may be used to select and view videos or receive podcasts on the communications device 110. As discussed above, the subscriber location 105 may further include one or more remote devices in its community of devices. For example, the remote devices in the community of devices may include the subscriber computer 125. In exemplary embodiments, the subscriber computer 125 may be part of the subscriber location 105 or a computer that is accessed remotely in order to receive podcasts and control, manage, and/or schedule content from the content services provider system 160 transmitted to the subscriber location 105 for rendering on the communications device 110. It is therefore appreciated that access to podcasts may be managed from locations remote to the subscriber location 105. It is understood by those skilled in the art that the subscriber computer 125 may include input and output devices, such as but not limited to a mouse, a keyboard, etc. As discussed further below, the aforementioned devices may all interact with the IPTV infrastructure 140 and the IPTV gateway 145. It is appreciated that any of the aforementioned devices may access podcasts according to exemplary embodiments. Furthermore, in exemplary embodiments, the communications devices described herein may have a network address associated with the communications devices such as an addressable uniform resource locator (URL), an Internet address, etc.
In exemplary embodiments, the system 100 may manage and access podcasts through the subscriber's IPTV-enabled device, such as the communications device 110, via the set-top box 111, the remote devices (e.g., the subscriber computer 125, etc.) or any other suitable devices. As such, to coordinate IPTV communication, the system 100 may further include the IPTV gateway 145 that is in communication with the IPTV infrastructure 140. The IPTV infrastructure 140 and the IPTV gateway 145 are used in conjunction to communicate via a network 135. For example, a suitable device (e.g., the communications device 110) at the subscriber location 105 may direct the IPTV infrastructure 140 and the IPTV gateway 145 to communicate with the content services provider system 160.
The network 135 may be an IP-based network for communication between a content services provider system 160 and the subscriber location 105 using communication devices such as but not limited to the communications device 110 (via the set-top box 111, for example). The network 135 may be implemented to transmit content from the content services provider system 160 to the subscriber location 105 via a broadband connection, for example. In exemplary embodiments, the network 135 may be a managed IP network administered by a service provider. The network 135 may also be implemented in a wireless fashion, e.g., using wireless protocols and technologies, such as Wi-Fi, Wi-Max, etc. The network 135 may also be a cellular communications network, a fixed wireless network, a wireless local area network (LAN), a wireless wide area network (WAN), a personal area network (PAN), intranet, metropolitan area network, Internet network, the Internet, or other similar types of network environments or other suitable network systems. The network 135 includes equipment for receiving and transmitting signals. In other exemplary embodiments, the network 135 may be a circuit-switched network such as a standard public switched telephone network (PSTN), a packet-switched network, or any combination thereof.
In exemplary embodiments, the IPTV infrastructure 140 may be an IP-based network that receives network data (e.g., podcasts) from the content services provider system 160 and the preferences server 150, and delivers the network data to the set-top box 111 for receipt or rendering on the communications device 110. Alternatively, the network data may be for receipt or rendering on the subscriber computer 125 or other suitable device.
In exemplary embodiments, as discussed above, the IPTV infrastructure 140 provides an interface between the subscriber location 105 and the IPTV gateway 145. In exemplary implementations, a terminal server 141, an application server 142, a media server 143, and a media content server 144 operate to interface communication between the subscriber location 105 via the set-top box 111, and the IPTV gateway 145. For example, in exemplary implementations, the set-top box 111 may provide a unique identification number so that the IPTV gateway 145 may route network data to the set-top box 111. The network data may include a podcast, and may be routed to the set-top box 111 according to the operations of the IPTV infrastructure 140 described below.
According to exemplary embodiments, the media content server 144 may operate to acquire podcasts and/or other similar content from the content services provider system 160. For example, the media content server 144 may search for podcasts or other similar content on the content services provider system 160. The media content server 144 may search for new or newly listed content, or simply search for all available content on the content services provider system 160. Upon searching the content services provider system 160 for content, the content may be transmitted to the media content server 144 (e.g., over the network 135 and/or the IPTV gateway 145). The media content server 144 may ingest the content to create a podcast or content listing. For example, the media content server 144 may transcode content received from the content services provider system 160 into a format suitable for playback/access on the IPTV infrastructure 140. Upon transcoding, or at substantially the same time as transcoding, the media content server 144 may create a podcast or content listing and make the listing available to the application server 142 and the media server 143. Further, the actual transcoded content or podcasts may be transferred to the media server 143 for access/playback on the IPTV infrastructure 140.
It is noted that according to at least one exemplary embodiment, podcasts may be transcoded from any format (e.g., MP3 format, MPEG format, or any other format) on the content services provider system 160 to WINDOWS MEDIA AUDIO (WMA) format. WMA format is an audio data compression technology developed by MICROSOFT®, and WMA may be used to refer to a MICROSOFT® audio file format or a MICROSOFT audio codec that forms part of the WINDOWS MEDIA framework. Furthermore, according to at least one exemplary embodiment, podcasts may be transcoded from any available format (e.g., MP3 format, MPEG format, or any other format) on the content services provider system 160 to WINDOWS MEDIA VIDEO (WMV) format. WMV format is an audio/video data compression technology developed by MICROSOFT®, and WMV may be used to refer to a MICROSOFT® video file format or a MICROSOFT® video codec which forms part of the WINDOWS MEDIA framework and may include audio/video information, such as audio/video podcast audio information. Therefore, according to exemplary embodiments, podcasts may be provided in audio form (e.g., audio podcasts, mp3 files, etc) and video form (e.g., video podcasts, MPEG files, etc).
According to exemplary embodiments, the media server 143 may receive transcoded podcasts or content from the media content server 144. The transcoded content may be in a format suitable for playback on a communications device with access to the IPTV infrastructure 140 (e.g., communications device 110/set-top box 111 and/or subscriber computer 125). Furthermore, the application server 142 may receive a podcast or content listing from the media content server 144. The podcast or content listing may include a listing of all transcoded podcasts available for access/playback through the IPTV infrastructure 140. Further, the application server 142 may be operatively connected to the terminal server 141. Thus, the podcast or content listing may be available to the terminal server 141. The terminal server 141 may launch applications on a set-top box (i.e., the set-top box 111) and may display the podcast or content listing on the communications device 110 through the set-top box 111. Further, a subscriber may select podcasts from the podcast or content listing for playback on the communications device 110. Moreover, podcasts selected by the subscriber may be rendered on the set-top box 111 by the media server 143 for playback on the communications device 110. Thus, according to exemplary embodiments, the system 100 provides podcasts to the subscriber via IPTV.
In exemplary embodiments, the IPTV gateway 145 may further interface with the various system 100 elements as described herein. For example, the IPTV gateway 145 is in communication with the preferences server 150 to pass notifications and messages (e.g., email messages) regarding permissions to create and edit podcast access information. For example, different members of the subscriber location 105 who share account services may have different access schedules. For example, one member may have a unique access schedule and another member may have a second unique access schedule with little to no overlap with the first access schedule. As such, each member may retrieve and edit those different schedules and be properly authenticated to retrieve and edit those schedules.
In exemplary embodiments, the IPTV gateway 145 may include a back end 147 and a front end 146. The front end 146 may be used to implement various provisioning activities such as but not limited to initial provisioning of IPTV addresses for the devices at the subscriber location 105. The back end 147 may be implemented for many of the podcast providing services, such as communicating with the content services provider system 160, passing messages and notification to the IPTV gateway 145, etc. As such, the back end 147 may include various elements (e.g., 148, 149) including but not limited to a caller ID handler, Short Message Service (SMS) handler, message handler, provisioning handler, etc. It is noted, however, that more or less elements may be included depending upon any particular implementation. Therefore, exemplary embodiments should not be limited by the particular number of elements (i.e., 148, 149) illustrated.
In exemplary embodiments, the IPTV gateway 145 may implement authentication using a high-speed processing device (e.g., a computer system) that is capable of handling high volume activities conducted via communications devices, and other network entities (e.g., parts of the IPTV infrastructure 140, network 135, etc.) via one or more networks (e.g., an IPTV infrastructure 140). The IPTV gateway 145 receives requests from one or more devices from the subscriber location 105 to access network services, such as podcasts. The IPTV gateway 145 may implement authentication software for restricting or controlling access to network. The IPTV gateway 145 may be in communication with a customer identity system (CIS) database, which stores subscriber credentials (e.g., subscriber names and passwords) for access to IPTV services.
In exemplary embodiments, as discussed above, the system 100 further includes the content services provider system 160, which is in communication with the IPTV gateway 145 via the network 135. In exemplary embodiments, the content services provider system 160 is implemented by a host system (e.g., a high-speed processing device) that provides content to its subscribers (e.g., a subscriber of the communications device 110), such as television programs, premium programming services, video on demand content, and Internet/Web content (e.g., podcasts, streaming media, etc.). In exemplary embodiments, the content is transmitted to the subscribers (e.g., at the subscriber location 105) via a broadband connection over an Internet Protocol (IP)-based network (e.g., the network 135). The content services provider system 160 may also provide an onscreen programming guide to subscribers that provides information about current and future programming available via the content providers' services, such as podcasts that are to be available in the future. Programming information provided by the onscreen programming guide may include current and future program listings including but not limited to program titles, program producers, begin time, duration of program, a date in which the program was produced, and a brief text description of the program.
In exemplary embodiments, the content services provider system 160 is coupled to a database 165, which may include podcasts. In addition, the database 165 may include one or more playlists for available podcasts. Such playlist(s) may be used by the media content server 144 to search for podcasts or content. In exemplary embodiments, access to the database 165 and the associated communication between the database 165 and the media content server 144 may be implemented by exemplary methods described herein.
FIG. 2 illustrates a flow chart for a method of providing podcasts 200 in accordance with exemplary embodiments. As discussed above, a subscriber may interact with a communications device (e.g., the communications device 110) and select podcasts and other content to access. In step 201, a request to render at least one podcast may be received (e.g., audio/video podcast). The request may be received by a set-top box from a subscriber issuing a selection on a communications device, for example, the set-top box 111 and the communications device 110 discussed above. Furthermore, the request may be received by an IPTV infrastructure from a set-top box or remote station (e.g., the subscriber's computer 125, set-top box 111, IPTV infrastructure 140). The request to render the podcast(s) may be a request to render podcast(s) available to the IPTV infrastructure 140. The podcast(s) may be stored in a format decipherable by the IPTV network, and may be rendered on a communications device.
Further illustrated in FIG. 2, upon receipt of a request to render at least one podcast, step 202 includes retrieving the podcast(s) to render. For example, the IPTV infrastructure 140 may retrieve the podcast(s) from a storage device located therein. The storage device may be included within a media server (e.g., the media server 143). The podcast(s) may be retrieved from the media server 143 and made accessible to the set-top box 111. For example, as set forth in step 203, the podcast(s) is provided to the set-top box 111. Additionally, the podcast(s) may be streamed to the set-top box 111 as streaming audio/video from the media server 143. Upon receipt of the podcast(s) or streaming audio/video of the podcast(s), the set-top box 111 may render the podcast(s) on the communications device 110. Alternatively, the podcast(s) may be rendered on a remote computer (e.g., the subscriber computer 125) or other communications device. Hereinafter, a method of providing podcasts is described with reference to FIG. 3.
FIG. 3 illustrates a flow chart for a method of providing podcasts 300 in accordance with exemplary embodiments. As illustrated in FIG. 3, the method 300 includes searching for podcasts at step 301. For example, a media content server of an IPTV infrastructure may search a content services provider system for podcasts and/or other content. The media content server may be substantially similar to the media content server 144 of FIG. 1. The IPTV infrastructure may be substantially similar to IPTV infrastructure 140 of FIG. 1. Furthermore, the content services provider system may be substantially similar to content services provider system 160 of FIG. 1. It is further noted that the content services provider system 160 may be remote to the IPTV infrastructure 140, may communicate with the media content server 144 over a network, and may provide a listing or playlist of available content to the media content server. Therefore, the media content server 144 may search through the listing of available content to locate podcasts.
The method 300 further includes downloading podcasts at step 302. As discussed above, the media content server 144 may communicate with the content services provider system 160 over a network connection. Thus, the media content server 144, having identified podcasts available on the content services provider system 160, may download any podcast available on the content services provider system. The media content server 144 may download newly listed podcasts, most recently updated podcasts, podcasts of a particular type or category, all podcasts, or only podcasts selected by subscribers of an IPTV system including the IPTV infrastructure 140. For example, subscribers of the IPTV system may select podcasts they wish to access over a communications device (e.g., the communications device 110 or subscriber computer 125). The IPTV infrastructure 140 may thus download podcasts selected by the subscribers. Alternatively, the IPTV infrastructure 140 may download all podcasts or a sub-set of podcasts depending upon implementation. As exhaustive description of all possible combinations of download implementations is not the purpose of this disclosure, all such implementations are considered to be included within the scope of exemplary embodiments.
Turning back to FIG. 3, the method 300 further includes transcoding podcasts at step 303. For example, the media content server 144 may transcode content received from the content services provider system 160 into a format suitable for playback/access on the IPTV infrastructure. It is noted that according to at least one example embodiment, podcasts are transcoded from any format on the content services provider system 160 to WINDOWS MEDIA AUDIO (WMA) format. Furthermore, according to at least one exemplary embodiment, podcasts are transcoded from any available format on the content services provider system 160 to WINDOWS MEDIA VIDEO (WMV) format. Therefore, according to exemplary embodiments, podcasts may be provided in audio form (e.g., audio podcasts, mp3 files, etc) and video form (e.g., video podcasts, MPEG files, etc).
Turning back to FIG. 3, the method 300 further includes updating a podcast listing at step 304. For example, upon transcoding, or at substantially the same time as transcoding, the media content server 144 may create a podcast or content listing and make the listing available to an application server (e.g., the application server 142) and a media server (e.g., the media server 143). Further, the actual transcoded content or podcasts may be transferred to the media server 143 for access/playback on the IPTV infrastructure 140.
The method 300 further includes providing podcasts to an application at step 305. For example, a terminal server (e.g., the terminal server 141) of the IPTV infrastructure 140 may launch an application on a set-top box, such as the set-top box 111, or communications device, such as the communications device 110, of the subscriber. The application may include an interface or graphical user interface the subscriber can interact with. The application may include the methodologies disclosed herein, and thus may be a podcast providing application. The interface may be rendered on a communications device such as the communications device 110 of FIG. 1, and may be accessed through buttons or controls on the set-top box 111, or through a remote control (e.g., the remote control 115). The subscriber may use the interface to select a podcast to access. Alternatively, the subscriber may utilize a remote communications device, such as a PDA, portable music player, or other device to select a podcast. Further, a media server (e.g., the media server 143) of the IPTV infrastructure 140 may include a podcast selected by the subscriber. The media server 143 may thus provide the podcast to the subscriber, either by way of streaming audio/video to the application, or by any other means, including but not limited to, streaming to portable or remote communications device, downloading to the set-top box 111 and rendering on the communications device 110, or other similar means.
Therefore, as described above, exemplary embodiments include methods of providing podcasts via IPTV. The methods may include receiving requests to render at least one podcast, retrieving at least one podcast, and providing at least one podcast. The methods may further include searching for podcasts, downloading podcasts, transcoding podcasts, updating listing of available podcasts, and providing podcasts. It is noted that although exemplary embodiments of the present invention have been shown and described with regard to certain operations (e.g., method steps 201-203 of FIG. 2, and method steps 301-305 of FIG. 3) being performed serially or consecutively, it will be understood that any combination of these operations may be performed simultaneously and in parallel.
