Decentralized method for generating an MPEG-2 multiprogram transport stream

摘要

Methods, systems, and apparatus for generating a multi-program transport stream comprising generating an empty bitstream comprising null packets, providing the empty bitstream to a first contributor wherein the first contributor replaces a null packet with a program packet resulting in a modified bitstream, and providing the modified bitstream to a second contributor. Also provided are methods for back channel management, contributor clock synchronization, and generating a contributor identification map.
