摘要
TD-MBMS系统是一种建立在TD-SCDMA系统平台之上,实现多媒体广播业务端到端的解决方案。广播形式的数字视频内容的压缩实现是TD-MBMS系统中实现多媒体广播业务的关键过程。选择高性能、国际标准和公正的无差别许可制度的H.264压缩标准,将带来高压缩率、高画质的视频效果。H.264视频压缩过程的关键步骤为宏块划分、运动估计、整形变化、熵编码。
TD-MBMS is a system built on the TD-SCDMA system platform, the realization of multimedia broadcasting services for end-to-end solutions. Broadcasting forms of digital video content compression is to achieve TD-MBMS Multimedia Broadcasting System to achieve the key business process. Choose high-performance, international standards and non-discriminatory licensing system just the H.264 compression standard, will bring high compression rate, high-definition video effects. H.264 video compression is a key step in the macro-block division, motion estimation, plastic change, entropy coding.
