Unequal Error Protection Based on Objective Video Evaluation Model

Abstract

Usually unequal error protection schemes mostly focus on protecting video data parameters with unequal rates or levels depending on their sensitivities to errors. This paper first proposes a novel effective and reliable objective video evaluation model based on fuzzy synthetic judgment. This model highlights a comprehensive evaluation by taking account of multiple properties of the compressed video which affect the whole video sequence, such as quality, fluency and motion information. Secondly, a novel unequal protection scheme is proposed. The protection levels are calculated according to the output of the fuzzy evaluation results. The whole coded video can be transmitted efficiently since the protection is based on the video quality evaluation. Simulation results demonstrate the advantages of the fuzzy objective video quality evaluation model, especially in comprehensive judgment of the whole video, and show the subjective quality improvement obtained by applying the proposed unequal protection approach.
