Rate-distortion optimized slicing, packetization and coding for error-resilient video transmission

by Enrico Masala, Hua Yang, Kenneth Rose, Juan Carlos, De Martin - in Proc. IEEE DCC
"... This paper presents an algorithm to optimize the tradeoff between rate and expected end-to-end distortion of a video sequence transmitted over a packet network. The approach optimizes the source coding parameters, slicing, network QoS class selection and/or error control coding parameters, and accou ..."

MACROBLOCK-BASED RETRANSMISSION FOR ERROR-RESILIENT VIDEO STREAMING

by J. Christian Schmidt, Kenneth Rose
"... This paper revisits the problem of source-channel coding for error-resilient video streaming. We propose a new method to enable adaptive redundancy in the bitstream: fine-grain retransmission. Redundancy decisions are made per macroblock (MB), which are locally adaptive and of low overhead, as oppos ..."

END-TO-END RATE-DISTORTION OPTIMIZED MODE SELECTION FOR MULTIPLE DESCRIPTION VIDEO CODING

by Brian A. Heng, John G. Apostolopoulos, Jae S. Lim
"... Multiple description (MD) video coding can be used to reduce the detrimental effects caused by transmission over lossy packet networks. Each approach to MD coding consists of a tradeoff between compression efficiency and error resilience. How effectively each method achieves this tradeoff depends on ..."

, accounting for both coding and packet-loss-induced distortions, as well as for the bursty nature of channel losses and the effective use of multiple transmission paths. With this model of end-to-end expected distortion, the encoder selects between MD coding modes in a rate-distortion optimized manner to most

Optimum End-to-End Distortion Estimation for Error Resilient Video Coding

by Yuan Zhang, Qingming Huang, Yan Lu, Wen Gao
"... Abstract. End-to-end distortion estimation plays an important role in error-resilient video coding. The intuitive method is to simulate the de-coding 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-e ..."

Rate-distortion methods for image and video compression

by Kannan Ramchandran - IEEE Signal Process. Mag. 1998
"... In this paper we provide an overview of rate-distortion (R-D) based optimization techniques and their practical application to image and video coding. We begin with a short discussion of classical rate-distortion theory and then we show how in many practical coding scenarios, such as in standards-co ..."

Joint Data Partition and Rate-Distortion Optimized Mode Selection for H.264 Error-Resilient Coding

by Yuan Zhang
"... Abstract—Data partitioning (DP) is an efficient error-resilient video coding tool. Its contribution to performance improvement in the error-prone environment arises from the superior error concealment mechanisms that are available with the help of protected data partitions. Since error-concealment i ..."

In this paper, a generalized end-to-end distortion model is proposed for the rate-distortion optimized coding mode selection, which fully utilizes the superior error-concealment mechanism in terms of DP. The proposed distortion
