영문 초록

Mobile multimedia services have rapidly evolved in the areas mainly including cell phones. Due to the increment of data traffic, processing load of server systems, network congestion and response time of clients also increase constantly. In this paper, a layered transmission technology is proposed of which the size of requested stream from clients has reduced and its performance is evaluated through the simulation. The layered transmission decreases data traffic to 78.5% averagely by converting format of data source in accordance with the playback performance of mobile devices. It is analyzed that decrement of streaming data size depends on EFS, resolution of LCD screen, and bytes per pixel. For real applications, layered transmission consists of modules based on filters using the Directshow considering portability, scalability, and reusability.
