A Scheme to Decrease Bit-Rate of Streaming Media for GPRS.
Hongtao Wang, Qing Shen, Liseng Xiang · International MultiConference of Engineers and Computer Scientists · 2006
The average downlink bandwidth of GPRS is about 25Kbps, while the bit-rate of typical streaming media is at least 100Kbps. It is an exigent job for GPRS business sys tem to decrease bit-rate of streaming media. In this paper we propose a novel scheme, which can select decoding parameters (based on the special attribute of different kinds of streaming media program) automatically to fit the bandwidth of GPRS. Our designation is promised to provide preferable visual quality for s treaming media running on GPRS networks. Some practice results are also proposed in this paper.
