Abstract
In this paper, we investigate the efficacy of the weighted prediction feature provided within H.264/AVC video coding standard for error resilient video streaming. Leaky prediction has been proposed for scalable and non-scalable video coding to effectively combat transport errors. However, all prior results are based on non standard coding methods and no results have been available on the effectiveness of leaky prediction that is supported by a video coding standard. The weighted prediction feature in H.264/AVC was originally designed for improving the coding efficiency especially in presence of fading in video sequences. This paper presents a performance analysis of H.264/AVC weighted prediction feature that balances the trade-off between coding efficiency and error resilience. A theoretical analysis of rate-distortion performance of leaky prediction is provided and closed-form rate-distortion functions are derived for the error free and error drift scenarios. The theoretical results conform well to the operational results with respect to different choices of the leaky factor.
