Description: H．264标准是ITU．T视频编码专家组和ISO IEC活动图像专家组共同组成的联合视频组开发的新一代视频压缩标准。H．264高效的编码效率建立在其高复杂度的编码算法基础上，而采用具有较强并行处理能力的C64x+DSP芯片的达芬奇(Davinci)技术平台，则以较高的运算性能和丰富的外围接口成为目前实现视频应
用系统的理想平台。本文对H．264编码算法的帧间及帧内预测算法进行改进，并进行了H．264编码器在DM6437平台上的移植和优化。-H．264 was jointly proposed by ITU—T Video Coding Experts Group and IS0／IEC
Moving Picture Experts Group．Compared with other former standards．H．264 has
incomparable advantage in the compression rate，video quality and the robust network stream．However，H．264 algorithm has high encoding efficiency but also high complexity，Davinci technology platform combines the DSP chip with C64x+
processor，providing a strong parallel processing capability．It has presently become an ideal platform in the area of video frequency application for its high computing
performance and rich peripheral interface．This paper provided a improved inter and intra flame prediction algorithm，furthermore transplanted and optimized the H．264
coder on DM6437．

Description: H.265是ITU-T VCEG 继H.264之后所制定的新的视频编码标准。H.265标准围绕着现有的视频编码标准H.264，保留原来的某些技术，同时对一些相关的技术加以改进。新技术使用先进的技术用以改善码流、编码质量、延时和算法复杂度之间的关系，达到最优化设置。具体的研究内容包括：提高压缩效率、提高鲁棒性和错误恢复能力、减少实时的时延、减少信道获取时间和随机接入时延、降低复杂度等。H264由于算法优化，可以低于1Mbps的速度实现标清数字图像传送；H265则可以实现利用1~2Mbps的传输速度传送720P（分辨率1280*720）普通高清音视频传送。(H.265 is a new video coding standard developed by ITU-T VCEG after H.264. H.265 standard revolves around the existing video coding standard H.264. The new technology uses advanced technology to improve the relationship between code stream, coding quality, delay and algorithm complexity. The specific research contents include: improving compression efficiency, improving robustness and error recovery ability, reducing real-time delay, reducing channel acquisition time and random access delay. Because of the optimization of the algorithm, H264 can realize the standard digital image transmission at a speed of less than 1Mbps. H265 can transmit 720P (resolution 1280g 720) HD audio and video transmission at 1mbps.)
