摘要
3G移动终端要求能够提供包含语音、数据和图像的多媒体业务,为此3GPP制定了第一个适合3G系统的基于电路交换的多媒体终端模型———3G-324M规范,该模型支持MPEG-4视频处理,它具有高压缩比和容错编码特性。在研究MPEG-4编解码算法基础上进行了MPEG-4视频编码的性能测试。
3G mobile equipment requires implementing not only speech services and low- speed data traffic, but also the increasing mobile multimedia services such as picture and video. 3G - 324M is the first multimedia terminal standard based on the circuit - switch suitable for 3G, which supports the MPEG - 4 coding due to its high compress efficiency and error- tolerance features. The performance test is carried out based on the research of the MPEG - 4 cede algorithms.
