Error Spreading: Reducing Bursty Errors in Continuous Media Streaming

With the growing popularity of the Internet, there is increasing interest in using it for audio and video transmission. Periodic network overloads, leading to bursty packet losses, have always been a key problem for network researchers. In a long-haul, heterogeneous network like the Internet, handling such an error becomes especially difficult. Perceptual studies of audio and video viewing have shown that bursty losses have the most annoying effect on people, and hence are critical issues to be addressed for applications such as Internet phone, video conferencing, distance learning, etc. Classical error handling techniques have focused on applications like FTP, and are geared towards ensuring that the transmission is correct, with no attention to timeliness. For isochronous traffic like audio and video, timeliness is a key criterion, and given the high degree of content redundancy, some loss of content is quite acceptable. In this paper we introduce the concept of error spreading, whi...
