Abstract
In this work, we improve the H.264 error resilient coding scheme in [1, 2] with a hybrid scheme that generates alternative SP macroblocks utilizing both multiple reference frames [1] and the concealed versions of corrupted frames [2]. The new scheme is more robust and able to work effectively under different coding environments. Although the bit rate overhead introduced by [1] and [2] is acceptable for some applications, we use an adaptive coding and bit stream replacement mechanism to reduce the overhead furthermore to meet the strict bandwidth constraints. Specifically, two different versions of alternative SP macroblocks are coded using different quantization levels. They provide different levels of error resilient performance with different bit rate consumptions. When the sender attempts to replace the originally coded version of a target macroblock in the bit stream, it will select one proper version according to the importance of the macroblock. The importance of the macroblock is measured by its influence to the subjective quality of the current frame and its impact to subsequent frames. The implementation and the standard conformance of the proposed scheme are detailed in this work.
