Abstract :
This paper is a contribution to studying the feasibility of multimedia applications over GSM HSCSD networks. We report simulation results of a mobile videophone application at bit rates ranging from 14.4 to 57.6 kbit/s. We focus on QoS of video data in both mobile-to-land and mobile-to-mobile H.324 connections. The results obtained in terms of visual quality, received PSNR, delay, and frame rate are promising, especially at bit rates of 28.8 kbit/s or higher
