    摘要： 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.

    摘要： Processing a video stream intended for a remote wireless device by a video processing system based upon identified area of interest information to produce an output video stream having lesser required data throughput. Operation commences with receiving the video stream and buffering the video stream. Then the video processing system identifies an area of interest corresponding to at least one video frame of the video stream. The video processing system the processes the video frames of the video stream based upon the identified area of interest to produce an output video stream. The video processing system then transmits the output video stream for delivery to the remote wireless device. Processing video frames of the video stream may include altering pixel resolution, color resolution, and/or cropping video information of the video frames outside of the area of interest.

    摘要： Processing video data for delivery to a remote wireless includes receiving video data from a video source and receiving position and motion information regarding the remote wireless device. Operation also includes, based upon the position and motion information regarding the remote wireless device, determining an anticipated Quality of Service (QoS) available for servicing of transmissions to the remote wireless device and determining video processing parameters based upon the video data and the anticipated QoS. Operation further includes processing the video data based upon the video processing parameters to produce an output video stream and transmitting the output video stream for delivery to the remote wireless device. Operation may also/alternatively include altering wireless transmission parameters of a transport stream servicing delivery of the video data to alter the anticipated QoS.

    摘要： A mobile video device includes a transceiver module that receives navigation data corresponding to a plurality of video programs including at least one unicast video program and at least one multicast video program, that transmits selection data and that receives a video signal in response thereto. An interface module receives interface data in response to actions of a user. A video display device generates a selection display based on selection display data in a video selection mode and that generates a video display in a video display mode based on the video signal. A video application module generates the selection display data based on navigation data, that generates selection data based on user interface data.
