摘要：
Transporting MPEG-4 video over the Internet is expected to be an important component of many multimedia applications. The ISMA (Internet Streaming Media Alliance) has defined two hierarchical profiles to stream video content on wireless and narrow band networks, and over broadband quality networks. The evaluation mechanisms to assess the quality of video will play a major role in the overall design of video communication. However, the ISMA (Internet Streaming Media Alliance) MPEG-4 video quality analysis has not been reported. This paper presents statistical video quality analysis for the ISMA MPEG-4 video clips. Shannon entropies and principle components are used to interpret the degraded video quality in video sequences. Moreover, the current trends in error resilient video coding techniques and the error control/resilience solutions will be discussed.
