Abstract

Delivering video over the Internet is an important component of many Internet multimedia applications. However, currently the Internet does not offer any quality of service (QoS) guarantees to video transmission. Loss of packets in a video frame not only degrades the video quality, but also allows the error to propagate in video stream. To solve this problem, several methods such as forward error control (FEC), retransmission, and error concealment have been proposed. However, these methods can not cope with bursty packet losses in the Internet. In this paper, we present a new error recovery scheme, called GOP based error spreading (GES), using packet interleaving at the group of picture (GOP) level. Experimental results show that the deterioration of video quality can be reduced by spreading the encoded data losses.
