“…Delay-sensitive application services such as interactive gaming, Internet protocol TV (IPTV) and Voice-over-IP (VOIP) are deployed nowadays, while the provision of Quality of Service (QoS) requirements in terms of loss, delay, and jitter for these services are very difficult than non-delay-sensitive services [1]. Digital Television is the most advanced version of TV technology improved in the last century [2].…”

This paper proposes a framework with scalable video coding (SVD) at the source joint with a 2-level Forward Error Correction (FEC) at the channel and superposition modulation for efficient IPTV video multicasting over IEEE 802.16 (or WiMAX), called 2-level FEC joint with Multiple Description Coding (2FMDC). Multiple description coding (MDC) on SVD that generates multiresolution of a video joint with superposition modulation (multi-resolution modulation) can overcome the channel diversity problem in wireless multicasting. In this framework, we use a 2-level FEC that enables a Subscriber Station (SS) to recover the lost frame and receive the video with more quality. The 2-level FEC denotes vertical FEC joint with horizontal FEC. Our proposed method applies identical redundancy compared with similar methods to the network traffic. Performance evaluation results demonstrate that using our proposed framework, an SS can achieve better video quality under multi-user channel diversity.
