  • Patent number: 9781450
    Abstract: A method of encoding and communicating video data comprises encoding a video data file (22) to create an encoded video data file (24) and sending the encoded video data file (24) to a destination (30). A portion of the encoded video data file (24) is sent to the destination (30) at the same time as the video data file (22) is being encoded. New header information for the encoded video data file (44) is sent to the destination (30) when sending the encoded video data file to the destination is complete. The destination (30) can then modify a header (46) of the encoded video data file (44) to include the new header information. This reduces the overall time taken for the video data file to be encoded and sent to the destination (30).

  • Patent number: 8923770
    Abstract: A wireless communication system that concurrently communicates information in multiple regulatory domains to facilitate audio/video media streaming and other high bandwidth operations. One domain may be licensed and the other may be unlicensed. Transmission in the licensed domain may occur in white space in the domain, and the amount of information transmitted in that domain may be limited by regulations. The amount of information conveyed in the licensed domain may also depend on channel conditions in either or both of the domains. As a result, the relative amount of information transmitted in each domain may vary dynamically. The system includes a transmitter that dynamically determines weighting coefficients applied to each of a plurality of channels to set power levels in both domains to achieve a desired metric for the overall communication. A corresponding receiver assembles the substreams into a stream that can then be displayed or otherwise processed.

  • Patent number: 8654873
    Abstract: In one embodiment, a Television (TV) receiver to perform a method of synchronizing a demodulator at a Viterbi decode input in the TV receiver using one or more bit de-interleaved even and odd Orthogonal Frequency Division Multiplexing (OFDM) symbols is provided. The method includes (i) performing a Viterbi decoding on the bit de-interleaved even and odd OFDM symbols when a frame boundary does not exist for the bit de-interleaved even and odd OFDM symbols, (ii) performing a convolutional encoding on an decoded data output of the Viterbi decoding, (iii) determining whether an output of the convolutional encoding of the bit de-interleaved OFDM symbols matches an input at a Viterbi decode, and (iv) determining whether the output of the convolutional encoding of the bit de-interleaved even and odd OFDM symbols matches with a SYNC pattern or a SYNC? pattern to obtain a RS packet align boundary.

  • Patent number: 8566869
    Abstract: Techniques are disclosed herein that provide a TV receiver that supports a set of existing iTV standards and proprietary iTV implementations. Further, the TV receiver can be extended to support additional iTV standards and proprietary iTV implementations. A digital television data stream is received and processed by a client. The digital television data stream is analyzed to determine which interactive television format is present. A registry of interactive television virtual machines is searched to determine whether a virtual machine is registered for the interactive television format. Each of the interactive television virtual machines is adapted for one of the interactive television formats. If a virtual machine that matches the interactive television format is found, it is loaded and hosted. Hosting the virtual includes providing services to the virtual machine through common application programming interfaces (APIs) machine includes. The common APIs may be used by any virtual machine that is loaded.

  • Patent number: 8325935
    Abstract: A wireless system including a first speaker and a second speaker, where the first and second speakers communicate with each other over a wireless link. In some configurations, the first speaker includes both a primary wireless interface for receiving audio from an audio source and a secondary wireless interface transmitting a portion of the audio to the second speaker. The speaker can incorporate Near Field Communication (NFC) technology to provide the wireless link between each other. The wireless system can be configured to synchronize audio output at the speakers, and can also include a second-speaker detection mechanism that permits the first speaker to be used in either a stand-alone mode, with audio output at only the first speaker, or full-headset mode, with audio output at both speakers when the second speaker is detected within wireless range of the first speaker.

  • Patent number: RE40606
    Abstract: In an effective display area, an additional information recognizing part 203 recognizes a standard of a broadcast wave, refers to a ROM 212 and selects a target value, and provides an internal clock of a video data reading part 205 and an internal clock of an OSD data reading part 206 with the target value. At a retrace internal, on the other hand, the additional information recognizing part 203 notifies an additional information synthetic position deciding part 210 of the standard of the broadcast wave. The additional information synthetic position deciding part 210 selects from a ROM 211 a target value for reading the additional information applicable to the notified standard, and outputs the target value to an additional information reading parts 207. When the standard of the broadcast wave is changed, target values corresponding to the changes are responsively selected from the ROM 212 and the ROM 211.
