A system for generating and sending a Logical Node identification signal as part of a data stream is disclosed. The system also includes subscriber stations capable of receiving and extracting Logical Node identification information from a data stream. The subscriber stations create new messages including the Logical Node identification signal and send the message to the transmission network system control, such that switching of data streams to an appropriate channel over the information transmission network is done consistent with the network topology.

Logical node identification in an information transmission network

A method and apparatus for forming and processing an MPEG transport stream such that programs may be inserted into, or deleted from, the MPEG transport stream without significant retiming operations.
