An adaptive MPEG2-TS packet scheduling discipline for multimedia broadcasting

摘要

Digital broadcasting can now be used for the transmission of not only video data but also IP data for http and FTP services. ATM over MPEG2-TS protocol stack is examined as one of the technologies that allows MPEG2-TS to offer efficient and flexible multiplexing. We have already proposed a scheduling discipline that is simple enough to implement in hardware and adaptively generates MPEG2-TS packets from the incoming ATM cells. This paper shows the results of our evaluation (simulations) into its efficiency in terms of multiplexing gain, delay performance, and fairness. The proposed scheduling discipline is found to be superior to the alternatives with respect to the multiplexing gain while offering excellent delay and fairness characteristics.
