Abstract
Techniques for lossless transport stream compression from constant bitrate to variable bitrate to constant bitrate are described. An exemplary method includes generating elementary stream data from an encoder; receiving the generated elementary stream data in a packetizer; generating a transport stream output in the packetizer; and in a statmux, for consecutive NULL packets generated by the packetizer, counting a number of NULL packets between non-null packets and dropping those NULL packets, modifying a next packet to indicate the number of NULL packets dropped using a field in the next packet, and sending the next packet to a receiver.
