Patent abstract
An advanced multiplexer designed and optimized for next generation on-demand video distribution is described. Features and capabilities include auto-discovery, channel-staggering and compatibility with static Virtual Channel Tables (VCTs). The multiplexer system facilitates auto-discovery by inserting identifiers into MPTSs (Multi-Program Transport Streams). These identifiers are echoed back to the multiplexer by the client set-top thereby indicating correspondence between modulators, service groups, and clients. When modulating multiple channels, FEC frames (Forward Error Correction frames) are staggered across channels to reduce correlation and clipping in the IFFT processor.
