  • Patent number: 8255962
    Abstract: A video processing system and method of operation transports a video stream between a video source and a remote wireless device and includes a communication interface and processing circuitry. The processing circuitry couples to the communication interface, establishes a reception verified communication link with the remote wireless device via the communication interface, and establishes a non-reception verified communication link with the video source via the communication interface. The processing circuitry further receives the video stream (and an audio stream) from the video source via the communication interface using the non-reception verified communication link and transmits the video stream (and audio stream) to the remote wireless device via the communication interface using the reception verified communication link.

  • Publication number: 20120210376
    Abstract: Processing a video stream using upon Program Clock References (PCRs) contained therein in preparation for transmission to a wireless device. Operation includes receiving video frames of the video stream, buffering the video frames, and extracting PCRs from at least some of the video frames of the video stream. Operation further includes, based upon at least the values of the PCRs, determining transmission parameters, and transmitting video frames of the video stream to the wireless device according to the transmission parameters. Operation may further include determining a round trip delay of transmissions to the wireless device and acknowledgements from the wireless device, adjusting PCRs of at least some video frames of the video stream based upon the round trip delay, and transmitting the video frames of the video stream to the wireless device.

  • Patent number: 8209733
    Abstract: A video processing system includes a communications interface and video processing circuitry. The communications interface receives video data from a video source, receives at least one operating parameter regarding a remote wireless device, and transmits an output video stream to the remote wireless device. The video processing circuitry couples to the communications interface, receives the video data and the at least one operating parameter, determines video processing parameters based upon the video data and the at least one operating parameter, processes the video data based upon the video processing parameters to produce the output video stream, and provides the output video stream to the communications interface for transmission to the remote wireless device. The video data (incoming video stream) may be processed by altering a frame rate, PCRs, pixel resolution, color resolution, color content, and/or region of interest content of the incoming video data to produce the output video stream.

  • Patent number: 8130642
    Abstract: Downstream synchronous multichannel (DSSM) communications are provided among a plurality of carriers, each being a completely DOCSIS™ 2.0-compliant downstream. The synchronous multichannels support communications with both DSSM-capable communications nodes and non-DSSM-capable communications nodes (e.g., legacy cable modems). Non-DSSM packets are transmitted on a single channel. DSSM packets are split into multiple pieces, which are transmitted simultaneously on all available channels. Since the physical delay variation (e.g., group delay change) across the adjacent carriers is small (on the order of a symbol time), the multiple pieces arrive at the receiving communications nodes at nearly the same time and can be reassembled with minimal buffering and no packet ordering problems. To avoid causing trouble for the non-DSSM-capable communications nodes, the packet pieces are encapsulated with a header that causes the non-DSSM-capable communications nodes to silently discard them.

  • Patent number: 8041351
    Abstract: In a wireless communication system, the time required to establish network connectivity for subscriber stations can be reduced by prioritizing and/or reducing contention between the subscriber stations. The subscriber stations can be divided into acquisition groups and assigned specific uplink channels on which to range. The subscriber stations can randomly or pseudo-randomly range on uplink channels.

  • Patent number: 8040864
    Abstract: Providing Quality of Service (QoS) information regarding video content delivery to a requesting wireless device. QoS/position information is first collected by, for each wireless device of a plurality of serviced wireless devices operating within a service area, receiving position information regarding a wireless device during delivery of video content and determining QoS provided during delivery of the video content, the QoS provided during delivery of the video content delivery varying over time and respective to the position information. The collected QoS/position information is then consolidated and a QoS map for the service area is produced based upon the consolidated collected QoS/position information. Finally, the QoS map for the service area is downloaded to the requesting wireless device. The QoS map may be tailored for the requesting wireless device based upon a current position/mobility of the requesting wireless device.

  • Patent number: 8005072
    Abstract: A plurality of CMTS devices are linked together and synchronized to facilitate communication between the respective CMTS devices and respective downstream cable modems. According to one embodiment of the invention, one of the CMTS devices is designated as a master device, and the other CMTS devices are designated as slave devices. The respective CMTS devices are connected to each other by means of a synchronization bus. The master CMTS device then generates and broadcasts a future time stamp value, which is received by the respective slave CMTS devices. When the time stamp counter in the master CMTS device reaches the transmitted value, a control signal is broadcast over the synchronization bus. The slave CMTS devices then retrieve the time stamp value and reset their respective local time stamp counters to the received value. In this manner, the CMTS devices are synchronized.
