Method and system for inserting digital video effects into a video stream in redundant paths before routing

摘要

A system and apparatus for generating an output signal includes a receiving system 160 generating a plurality of signals having a first format and communicating the plurality of signals simultaneously through a primary path and a secondary path. A digital video effects module 240 inserting a digital video effect into at least a first signal of the plurality of signals in a primary path. An encoder 182 encoding the plurality of signals into a plurality of transport streams and a multiplexer. A local area network 130 routes the plurality of transport streams to the multiplexer to form a combined signal. A modulator 210 modulates the combined signal to form a modulated signal and a system 202 forms the output signal from the modulated signal.
