H.264 Packetization Algorithm Research Based on Real-time Stream Media Transportation System

Real-time stream media transportation over wired/wireless network has become a focus of research.And the packetization algorithm is the key technology.This paper describes a H.264 real-time transmission module based on RTP,and puts forward a RTP packetization algorithm for H.264 video which is called Hybrid Mode Packetization(HMP).HMP considers video stream content correlation and unequal protection of important information with H.264 NAL video features.Simulation results show that HMP can achieve good perceptual picture quality for H.264 video under packet-loss network conditions.
