| Abstract: | It is an effective way to transmit multimedia applications with mobile access by varying transmitting signal's parameters according to both the natures of source data and the conditions of current channel. In this paper, we classify the multimedia applications based on their requirements in bit throughput rate, bit error rate and delay, and then introduce a new layered structure for future simultaneous multimedia transmissions with mobile access. Finally a technical solution is proposed for adaptive broadband multimedia digital transmissions. |
