Performance analysis of interleaving for video communications over ATM networks

This paper addresses the importance of interleaving for digital video communication over B-ISDN such as an ATM network. It provides the appropriate solution based on a good knowledge of both the video system interface design and broadband network capabilities. An interface between MPEG-2 and the ATM network architecture is studied to improve the video visual quality. The presented approach tries to overcome the difficulty imposed by traditional random cell discarding due to the bursty and variable bit rate transmission, nature of compressed video. The presented approach is guided by using a interleaving technique. In order to support these mechanisms, an enhancement to the ATM adaptation layer is performed. The performance evaluation has shown a better video quality compared with the sequence transmitted without the interleaving technique.
