    摘要： Transmitting streamed video to at least one wireless terminal by a wireless network having a channel frequency reuse pattern. The wireless network receives a request for the streamed video from the at least one wireless terminal and receives position information from the at least one wireless terminal requesting the streamed video. The wireless network selects a transceiving device to service transmission of the streamed video to the at least one wireless terminal. The transceiving device is allocated a first channel frequency set of the channel frequency reuse pattern. The wireless network or a component thereof selects a channel from a second channel frequency set that is different from the first channel frequency set. The transceiving device then, using a directional antenna, transmits the streamed video to the at least one wireless terminal in a direction based upon the position information using the selected channel.

    摘要： Processing video data for delivery to a remote wireless device 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 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.
