H.264 is a new digital video compression format,proposed by ISO (international standard organization) and ITU (International Telecomunication Union),after MPEG4, it remains the feature and essence of former compression technology ,and has many unique advantages as following:
1．Low bit stream： comparing to MPEG2 and MPEG4 ASP compression technology,at the same image quality condition,the video file compressed by H.264 algorithm is just 1/8 volume of MPEG2,1/3 of MPEG4.
2．High quality ： H.264 video algorith could supply continous,fluent high quality image (DVD high definition image)
3．Compatibility to mistakes ： H.264 supplies necessary tools to solve the problem of frequent losing data package in un-stable network condition.
4．Strong adapt ability for network: H.264 supplies Network Adaptation Layer, makes files able to transfer on different network (such as internet,CDMA,GPRS,WCDMA,CDMA2000 etc) . |
