Unified quantization parameter and frame size control for quality of experience optimization in wireless multimedia communications

Published: 09 October 2015 Publication History

Abstract

The quantization parameter (QP) has very important impact on the compression rate, Quality of Experience (QoE) and packet error rate in wireless H.264 multimedia communications. In this paper we show in order to achieve desirable QoE in wireless multimedia communication systems, a good estimate for the adaptive QP is required. In order to achieve good quality of video after compression, we propose a simple estimation model with methodology to decide the adaptive value of QP for each video frame in error prone wireless channel. The simulation results show that the proposed technique can improve the QoE with adaptive QP control.
