基于3G的视频会议中图像质量的研究

摘要

This paper bases H. 264/AVC video standard, through analysis of 3G wireless features and various error resilience strategies, makes redundant slices technology and other ways of error resilience methods combining the practicality of error resilience program to address the high error rate in the 3 G video conferencing environment issues in the image quality. The results show that in the high error rate of 3G environment; this method can significantly improve the subjective and objective quality of reconstructed images with＇ good practical.%本文基于H．264／AVC视频标准，通过对3G无线特性和各种容错技术的分析，提出了采用冗余片技术与其它容错方式相结合的方法解决在高误码率的3G环境下视频会议中图像质量的问题。实验结果表明，在高误码率的3G环境下，该方法可显著提高熏构图像的主客观质量，具有良好的实用性。
