Abstract
A system, method, apparatus and computer code are provided for producing coherent symbols from digital RF transmitters. A multiplexer receives a digital signal containing content data to be broadcast from the digital RF transmitters and inserts a first initialization packet into the digital signal, where the initialization packets implicit position in the digital signal will signal data framing in the digital RF transmitters. Where the initialization packet contains stuff bytes for deterministically initializing Trellis coders in the digital RF transmitters. A transport stream emitter transmits the digital signal to the plurality of digital RF transmitters.
