Abstract:
A method for splicing bitstreams, said bitstreams comprising a plurality of information segments representative of a sequence of information frames, said method comprising the steps of:monitoring a first bitstream to detect an exit indicium, said first bitstream being coupled to an output and including at least one of said exit indicium, said exit indicium indicative of an appropriate last information segment of a splicing segment;providing a second bitstream, said second bitstream including at least one entrance indicium, said entrance indicium indicative of an appropriate first information segment of a splicing segment; andcoupling said second bitstream to said output in response to a splice decision signal, a detection of said exit indicium in said first bitstream and a detection of said entrance indicium in said second bitstream, said step of coupling comprising the steps of:decoupling said first bitstream from said output at a detected exit indicium;coupling said second bitstream to said output at a detected entrance indicium; andtransmitting a splice acknowledgment signal.
