Abstract

Streaming to a terminal (150) by using a duplicating switch (130) to receive a stream of data units, using the duplicating switch (130) to store content from the stream, using the duplicating switch (130) to generate a second stream that incorporates the content that was stored and address information corresponding to more than one terminal (150) whose addressing information was not part of the first stream, and using the duplicating switch (130) to make the second stream of data units available to two or more terminals(150).
