Provided are methods and systems for substituting programs within an existing multi program transport stream (MPTS). Methods can include identifying a first packet associated with a first input program, determining if the first packet is a packet to be replaced, substituting a second packet for the first packet if the first packet is the packet to be replaced, and applying a timestamp at the stream processor to the second packet with a time for the second input program. |
