Optimum End-to-End Distortion Estimation for Error Resilient Video Coding
End-to-end distortion estimation plays an important role in error-resilient video coding. The intuitive method is to simulate the decoding process many times at the encoder, as used in the H.264 test model. However, the computing complexity is very high. In this paper, an optimum end-to-end distortion estimation scheme is proposed. Concretely, the correlations of the potentially propagated erro...
متن کاملError-resilient video coding with end-to-end rate-distortion optimized at macroblock level
Intra macroblock refreshment is an effective approach for error-resilient video coding. In this paper, in addition to intra coding, we propose to add two macroblock coding modes to enhance the transmission robustness of the coded bitstream, which are inter coding with redundant macroblock and intra coding with redundant macroblock. The selection of coding modes and the parameters for coding the...
متن کاملEnd-to-End Rate-Distortion Optimized MD Mode Selection for Multiple Description Video Coding
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Multiple description (MD) video coding can be used to reduce the detrimental effects caused by transmission over lossy packet networks. A number of approaches have been proposed for MD coding, where each provides a different tradeoff between compression efficiency and error res...
متن کاملOptimal End-to-end Distortion Estimation for Drift Management in Scalable Video Coding
This paper is concerned with performance optimization of point-to-point communication of scalable video over lossy networks. The premise of the work is: (i) Decoder drift due to prediction should be controlled but not altogether disallowed; and (ii) Reaping the full benefits of drift management techniques requires accurate estimation of end-to-end distortion. A variant of the recursive optimal ...
متن کاملError Resilient Schemes for Region of Interest based Video Coding
In video applications, not all regions of a particular frame are of equal importance. There are one or more regions in a video frame that have higher importance than the rest of the frame. In medical videos, only part of the frame is of high diagnostic importance. The medically important region can be coded with higher bit allocation. This paper reviews the current error resilient, region of in...
