Adaptive QoS control of multimedia transmission over band-limited networks
Tóm tắt
Consumers increasingly demand high quality of service (QoS) for multimedia applications. Application-layer QoS control mechanisms that do not make specific references to coding semantics tend to provide the most robust solutions for delivery of multimedia data over band-limited networks. We propose an adaptive and robust QoS algorithm for band-limited networks that integrates explicit receiver-sender rate control, rate shaping with multiple quantization parameters and adaptive forward error correction (FEC). Experimental results indicate that an average improvement of 0.5 dB PSNR can be achieved compared to other methods.
