Abstract

This article describes a cooperative framework for the transport and the QoS control of delay-tolerant video streaming applications using MPEG-2 encoding and broadband ATM networks. The proposed framework integrates three components: (1) a dynamic video frame-level priority assignment mechanism based on MPEG data structure and feedback from the network (DexPAS); (2) an audio-visual AAL-5 SSCS with forward error correction capabilities (AV-SSCS); and (3) an intelligent packet video discard mechanism called FEC-PSD, that adaptively and selectively adjusts cell drop levels to switch buffer occupancy, video cell payload type and forward error correction capability of the destination. The proposed QoS control and video delivery framework is evaluated using simulation
