    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 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.
