  • Patent number: 12375737
    Abstract: Systems, methods, and devices for supporting advertisement (ad) insertion into a media stream. The device receives notification of an upcoming ad break within the media stream, determines whether the upcoming ad break contains only pre-scheduled spots, and if the upcoming ad break does not contain only pre-scheduled spots, determines whether the upcoming ad break includes any addressable spot based on a broadcasting schedule stored on the device. Otherwise, the device sends a request with information about the at least one addressable spot and the upcoming ad break to an ADS proxy hosted by a client ad server unit within the content delivery network, receives a response message from the ADS proxy identifying a default asset for each addressable spot, retrieves the at least one default asset from a content distribution network, and sends the at least one default asset to a splicer for insertion within the media stream.

  • Publication number: 20250175657
    Abstract: Various methods and processing systems are disclosed that provide a computing device in a multi-rail splicer system for inserting content. The method may include receiving a first cue request message from a first splicer associated with a first rail in the multi-rail splicer system, determining a first splice time value for the first splicer based on a time included in the received first cue request message, receiving a second cue request message from a second splicer associated with a second rail in the multi-rail splicer system, determining a second splice time value for the second splicer, sending commands to insert the content stream into their respective rails at their determined splice time values, multicasting a content stream to the first and second splicers, the content stream including audio, video, and an ad beacon in a data packet identifier (PID), and consolidating content insertion results into a single verification file.

  • Patent number: 11303682
    Abstract: A resource such as a server derives multiple streams of data based on particular content. Each of the multiple streams of data is encoded to enable play back of the content according to a different level of quality. The server transmits the multiple streams of data of differing levels of quality on a multicast link downstream to one or more intermediate nodes that, in turn, distribute the streams of data to end users. For example, an intermediate node retrieves a respective stream of data from the multiple streams of data and forwards the selected stream of data over a second portion of the multicast link to a respective client device. The intermediate node can transmit a different stream of data to the respective client device depending on available bandwidth. The client device plays back the transmitted stream of data to produce a rendition of the particular content.

  • Patent number: 9451337
    Abstract: Techniques disclosed herein include systems and methods for transmitting TV program related content to IP connected devices on a home network, or other local area network. Users can watch television while simultaneously receiving content related to TV programs currently being displayed on a television. TV centric and TV program related content can be transmitted to IP connected devices. Moreover, this TV program related content can be displayed at the same time as a television program is being displayed on a television. As such, the system can provide media synchronization within home network using the set-top box as a gateway for delivering the content. Users can watch TV at home, and at the same time receive TV program related content on a laptop, tablet computer, mobile phone, etc.

  • Patent number: 9210476
    Abstract: Methods and apparatus for supplying unbound applications with data via in-band program channel signaling are described. Unbound applications are STB or other customer premise device applications which continue to run when a tuner in the device changes between program channels. Applications executed in a STB, in accordance with the present invention, e.g., eBIF applications, continue to run despite changes in program channels with data being supplied via in-band signaling, out of band signaling, or a combination of in-band and out of band signaling. The methods and apparatus are well suited for supporting delivery of program catalog information relevant to an individual program channel using in-band signaling reducing or eliminating the need to delivery a multi-channel program catalog via out of band signaling to support various VOD applications.
