A buffer-driven network-adaptive multicast rate control approach for Internet DTV

Abstract

The current Internet does not offer any quality of service guarantees or support to Internet multimedia applications. There are two requirements of multicast sending rate for Internet DTV: (1) it can adapt well to the change of network congestion; (2) it can meet the requirements of decoding rate. The difficulties of Internet DTV stream multicast are analyzed, then a multicast rate control approach for network DTV stream based on buffer management is given, which can suit for the change of network traffic and satisfy the requirement of DTV decoder by controlling sending rate logically. The test results show the good practical value.1 © Springer-Verlag Berlin Heidelberg 2005.
