  • Patent number: 10382837
    Abstract: Techniques for linking and browsing media on a television (TV) are provided. A selected program, which is associated with a channel of the TV, is detected and additional content, which is associated with that channel and/or the selected program, is dynamically acquired from one or more external sources. The additional content is formatted as links and simultaneously presented within a display of the TV along with the selected program that continues to play on the TV. Furthermore, activation of any link results in the additional content being dynamically acquired and presented within the display.

  • Patent number: 10085054
    Abstract: A method includes receiving a request for media content at a residential gateway from a device coupled to the residential gateway and sending a media content request to a server based on the request. The method includes receiving a video data stream of the media content at the residential gateway. Data packets of the video data stream enable generation of the media content at a first resolution. A first subset of the data packets include tags that enable identification of particular data packets usable to generate the media content at a second resolution that is lower than the first resolution. The method also includes determining a display characteristic of a display device coupled to the device and sending the particular data packets to the device when the display characteristic indicates that the device is to receive the media content at the second resolution.

  • Patent number: 9554180
    Abstract: A system includes a converter to receive a receiving a satellite signal at first transport frequencies and to convert the satellite signal to second transport frequencies and a processor. The processor removes a radio frequency portion from the satellite signal without altering a sequence of media contents of a moving picture experts group portion of the satellite signal and without altering a quality of the media contents of the moving picture experts group portion. The processor determines whether the media contents include an error and corrects the error in the moving picture experts group portion with error correction data of the satellite signal. The processor encrypts the media contents to produce an encrypted digital moving picture experts group transport stream signal. The processor also sends the encrypted digital moving picture experts group transport stream signal to a modulator.

  • Patent number: 9165317
    Abstract: A dynamic repository (either storing digital data content or pointers to stored digital data content) works in conjunction with a plurality of interfaces to manage digital content and digital rights policies associated with one or more users. Digital rights policies are unique to each user and such policies define access to digital content in the repository. The user's digital rights policy indicates the level of access a user has to digital content in the repository (e.g., the policy could indicate that the user has authorized access to a particular file for a period of seven days). The interfaces linked with the content repository are used to access and manipulate the digital data content (based upon each user's digital rights policy) and the digital rights policies stored in the content repository.

  • Patent number: 8966563
    Abstract: A system includes a signal-processing engine configured to generate a video data stream including a plurality of data packets based on a received video signal. A first subset of the plurality of data packets is usable to generate a video display of content having a first quality and all of the plurality of data packets are usable to generate a second video display of the content having a second quality. The second quality is higher than the first quality. The signal-processing engine is further configured to distinguish the first subset of the plurality of data packets from other data packets of the plurality of data packets by applying a tag to particular data packets to form tagged data packets. The system also includes a transmitter coupled to the signal-processing engine and configured to transmit the plurality of data packets of the video data stream.
