Abstract: A video processing system includes a video device that generates a request corresponding to video content. A conditional access module generates a video signal for transmission to the video device during a first time period, and terminates transmission of the video signal when the request is not authenticated during the first time period. In a further embodiment, the conditional access module generates a video signal for unscrambled transmission to the video device during a first time period, terminates the unscrambled transmission of the video signal at the expiration of the first time period, and continues with scrambled transmission of the video signal after the first time period.

Abstract: Transmitting signals to at least one wireless terminal by a wireless network having a channel frequency reuse pattern. A transceiving device within the wireless network selects a channel in contradistinction to the channel frequency reuse pattern to service transmission of a signal to the at least one wireless terminal.

Abstract: A video transmission system includes a video server module that selectively operates in a unicast mode and a multicast mode, wherein the video server module generates a video signal that includes a unicast video signal when the video server module is in the unicast mode and that includes a multicast video signal when the video server module is in the multicast mode. A wireless access device transmits the video signal to at least one mobile video device.

Abstract: A video processing system includes a video transcoder that receives a independent video layer stream and a first dependent video layer stream that requires the independent video layer for decoding, the video transcoder generating a transcoded video signal based at least one of the independent video stream and the dependent video layer stream.

Abstract: A video processing system includes a video encoder that encodes a video stream into an independent video layer stream and a first dependent video layer stream that requires the independent video layer for decoding. A scrambling module scrambles the independent video layer stream to produce a scrambled independent video layer stream and leaves the first dependent video layer stream unscrambled.
