  • 摘要:Digital video techniques have been used for a number of years, for example in the television broadcasting industry. However, until recently a number of factors have prevented the wide spread use of digital video. An analog video signal typically occupies a bandwidth of a few mega hertz .However, when it is converted into digital form, at an equivalent quality, the digital version typically has a bit rate well over 100 Mbps. This bit rate is too high for most networks or processors to handle. Therefore, the digital video information has to be compressed before it can be stored or transmitted Over the last couple of decades, digital video compression techniques have been constantly improving. Many international standards that specialize in different digital video applications have been developed or are being developed. At the same time, processor technology has improved dramatically in recent years. The availability of cheap, high-performance processors together with the development of international standards for video compression has enabled a wide ran ge of video communications applications
