Multimedia Services for Mobile WiMAX

Abstract

Mobile WiMAX is suitable for video-on-demand as well as broadcast TV services. Delivery of video streams over an IP packet-switched network, which includes broadband wireless access, requires rate or congestion control along with methods to protect the compressed stream from the impact of channel conditions. The Chapter considers possible solutions for both these requirements: multi-connection streaming overcomes the risk of poor channel utilization when restraining rates due to detected packet loss, while data-partitioning is a form of error resilience which includes the possible of graceful quality degradation. In the Chapter, ratelesschannel coding is adaptively employed along with error control. The Chapter also surveys the WiMAX option, acknowledging demerits as well as merits of this technology, and considering what other investigations have taken place to deliver multimedia services over broadband wireless.
