Abstract

With the advent of third-generation wireless cellular systems (3G), video streaming over wireless networks has become ubiquous. However, the characteristics of wireless systems provide a major challenge for reliable transport of real-time multimedia applications since data transmitted over wireless channels is highly sensitive to noise, interferences and multipath environment, which can cause both packet losses and bit errors. Latest 3GPP/3GPP2 standards require 3G terminals to support MPEG4-AVC/H.264. The ISO/ITU video standard has inbuilt error resilience tools, and provides either the use of a classical packetization scheme or a RTP-based packetization scheme. Classical transport schemes over wireless networks use the RTP/UDP/IP scheme. In this article, some experiments are realized to analyse the performances of UDP/IP transport over 3G networks, without using RTP.
