Adaptive High Definition MPEG-2 Streaming using Frame-based Prioritization over IEEE 802.11a WLAN

摘要

In this paper, we propose a practical implementation of network-adaptive high definition (HD) MPEG-2 streaming using frame-based prioritized packetization over the IEEE 802.11a WLAN. The proposed adaptive streaming system nicely combines frame-based prioritized packetization and priority-based dropping based on the end-to-end network monitoring. With the popular VideoLAN open software, we develop a real-time MPEG-2 TS (transport stream) parsing tool to provide the guide for required frame-based prioritization. The implemented system is evaluated over an IEEE 802.11a WLAN testbed and the experiment results verifies the intended the end-to-end QoS adaptation capability.
