LOAD CHARACTERIZATION OF VIDEO STREAMS

摘要

Distributed video applications are an emerging area of our modern information society. They process video data streams produced by video encoders. This processing imposes high storage and throughput requirements on computer and communication systems. For instance realtime video communication like video conferencing does not perform very favorable when run over a best-effort network like the Internet. Because of data losses or high delays as consequences of congestions and bottlenecks the service offered by such a video application can deteriorate. To support the solution of such problems this paper presents a study of the output process of video encoders to quantify and characterize the requirements of video applications, in particular the traffic characteristics of H.26x-encoded video streams are investigated.
