  • Patent number: 10009647
    Abstract: A system transmits human interface data (HID) as ancillary data to a television receiver over white space. Content on a user mobile device may be wirelessly displayed on an external display device. It may be desirable to have user interactions with the mobile device (such as controls for video games) displayed on the external display device in a manner that does not suffer from the latency of standard video being set to the display device. The HID may be captured and processed separately from the video data. The HID may be formed into a transport stream for transmission over white space. The HID may be included as ancillary data in the transport stream. Timestamps may be used to coordinate the transmission of the HID as well as its processing when received by a television receiver.

  • Patent number: 9942606
    Abstract: Television white space devices are operable to communicate information over television white space and, more specifically, to quiet a transmitter for sensing signals in the television white space. A method for inconspicuous quieting of the transmitter in a television white space device inserts, from an application layer, information into a transport stream for transmission by the transmitter of the television white space device to produce a null window of time within the transport stream at a predetermined time. The method also transmits the transport stream by the transmitter of the television white space device and quiets the transmitter during the null window of time. The method senses, by a white space sensor of the television white space device, existing signals in the white space during the null window of time.

  • Patent number: 9736548
    Abstract: An end-to-end multimedia streaming system can include a streaming server and a destination. The streaming server includes a content source, which sends multiple description coding-encoded content over a plurality of paths to the destination. The destination includes an aggregator for aggregating the descriptions from the multiple paths, decoding and recombining them to recover the content. A feedback sender at the destination generates traffic performance variables based on the channel conditions of the multiple paths, and sends these variables to a feedback receiver at the streaming server. The feedback receiver utilizes the feedback information to make adjustments to the transmissions of the content, and to synchronize the transmissions over the multiple paths.

  • Patent number: 9712573
    Abstract: This disclosure relates to techniques for synchronizing playback of media data between a source device and one or more sink devices in a Wireless Display (WD) system. WD systems enable mobile devices to share a local display of the source device with remote sink devices. The techniques of this disclosure include a management procedure at the source device to select a universal queue size for the source device and the participating sink devices. The source device selects the universal queue size based at least on supported queue sizes of the source device and the sink devices. The media packets are then held in queues having the universal queue size at the source device and the sink devices. The uniform queue size combined with compensation for transmission delay enables each of the devices to begin processing the media packets at the same time.
