| In recent years, with the increase of the wireless business, people are more and more interested in videophone, and wireless video communication becomes the new demand of the wireless communication. However, because of some problems in wireless video communication, such as bandwidth request, real-time requirement, power restriction, channel noise, video coding and transmission base on wireless technology become a hot research topic in information science and technology. Therefore, the key problem is how to design a video compression algorithm aimed at network characteristics efficiently.In the paper based on H.263 standard framework (a video coding standard which is ITU-T aimed at video applications with low bit rate), status quo of wireless video communication system, the development history of video image compression coding and standard are analyzed. Moreover, the basic principle, compression algorithm and practice... |
