Abstract

See full text

An apparatus comprising an input capable of receiving a bandwidth optimized transport stream is provided. The bandwidth optimized transport stream can be produced by receiving a transport stream of variably compressed program data bearing transport packets and one or more null transport packets. One or more of the null transport packets is selectively replaced with another to-be-remultiplexed non-null data bearing transport packet. Independently of determining an amount of information carried by a program data bearing transport packets from time to time in the received transport stream, at least one selected program bearing transport packet is scheduled for output in an output remultiplexed bitstream.
