ABSTRACT:
An apparatus for generating an output signal includes a receiving system160generating a plurality of signals having a first format, an insertion module166inserting a source identifier into the plurality of signals, an encoder182encoding the plurality of signals into a plurality of transport streams and a multiplexer210. A local area network130routes the plurality of transport streams to the multiplexer210to form a combined signal. A processing system200compares the source identifier to an expected source. When the source identifier corresponds to the expected source, the processing system200modulates the combined signal to form a modulated signal. When the source identifier does not correspond to the expected source, the processing system200changes the combined signal. A modulator214modulates the combined signal to form a modulated signal. A system202forms the output signal from the modulated signal.
