ABSTRACT:
Systems and methods are provided in which video information streams are encoded and transmitted with optimal utilization of constrained bit-rate channel. In accordance with one embodiment, among others, a system is provided, which includes synchronous multi-channel encoder (SMEs), a system multiplex controller (SMC), switches, and a multiplexer. In combination, these components receive an input video signal, and produce encoded video bit streams from the received input video signal. Each encoded video bit stream is substantially identical to other encoded video bit streams, but each encoded video bit stream has a different bit rate than the other encoded video bit streams. An optimal encoded video bit stream is determined from the encoded video bit streams. That optimal encoded video bit stream is selected, multiplexed, and than delivered to the output.
