A Multi-Level Adaptive Scheme for Multimedia Transmission over Wireless Channels
Husameldin Mukhtar, Mohamed S. Hassan, Taha Landolsi · 2010
Delivery of multimedia contents over unreliable channels poses several challenges. In particular, video streaming has strict requirements on bandwidth, delay, and loss rate. In this paper, we propose the integration of several approaches to overcome these challenges. These approaches are adaptive modulation, adaptive channel coding, adaptive playback, and bitstream switching. The proposed adaptive scheme significantly improves the effective channel bitrate. It also accommodates variations in the channel condition and subsequently ensuring uninterrupted video playback.
