Abstract
In the lack of system and network support for guaranteed services, application-level QoS control mechanisms become indispensible. This paper presents several adaptive QoS control techniques for video conferencing under run-time resource constraints. Due to the importance of multimedia security to QoS, this paper also presents a fast MPEG video encryption alrogithm that bounds computation time for any video frame size and is robust to both plaintext and ciphertext attack. Our implementation shows that the algorithm adds only small overhead to video compression process, therefore minimizing its QoS impact on video streams while offering security to digital video applications.
