DEVICE, SYSTEM AND METHOD OF MULTI-CHANNEL PROCESSING

摘要

Briefly, some embodiments of the invention may include devices, systems and methods of multi-channel processing. For example, a set-top box in accordance with an embodiment of the invention may include a front-end to receive a downstream signal carrying audio/video data representing a first plurality of channels, including one or more scrambled channels; a de-multiplexer to de-multiplex said downstream signal into a second plurality of channels including at least one of said one or more scrambled channels; a descrambler to descramble said one or more scrambled channels into one or more, respective, descrambled channels; a bouquet producer to receive said second plurality of channels and said one or more descrambled channels and produce a bouquet including said second plurality of channels and said one or more descrambled channels; a multiplexer to receive said bouquet and produce an output signal carrying audio/video data representing said second plurality of channels, including said one or more descrambled channels; and an output unit to provide said output signal to one or more audio/video devices.
