H.263视频编解码系统的软件实现 A SOFTWARE IMPLEMENTATION OF H.263 VIDEO CODEC 罗学金 Luo Xuejin 1 first-author 蔡芹 Cai Qin 1 刘立海 Liu Lihai 1 苏祥芳 Su Xiangfang 1 王延平 Wang Yanping 1 武汉大学电子信息学学院 武汉大学电子信息学学院 College of Electronic Information, Wuhan University College of Electronic Information, Wuhan University 提出了一个完整的Ｈ．２６３视频编解码系统的软件实现方案．采用多线程技术同时完成编码、解码发送、接收、显示等多个任务，在编码模块中采用汇编语言，提高了执行速度，引入ＭＭＸ技术后，运行速度得到进一步提高． A software implementation of a complete H.263 video coding and decoding system is introduced. Multithread technology is used in this design to operate concurrently with several tasks such as encoding, decoding,displaying, data sending and receiving. Using asscmbly languagc in thc design of coding part can greatly improve the speed of the codec. The speed is improved further after applying MMX instrution set. \ \ 视频编码 H.263 多线程 MMX video coding H.263 multithread MMX TN941.1 武汉市科委攻关计划基金 1999-01-01 2021-04-01 1
