Adaptive Spectral Separation Two Layer Coding with Error Concealment for Cell Loss Resilience
This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...
متن کاملTitle of Dissertation : ERROR RESILIENCE IN HETEROGENEOUS VISUAL COMMUNICATIONS
Title of Dissertation: ERROR RESILIENCE IN HETEROGENEOUS VISUAL COMMUNICATIONS Meng Chen, Doctor of Philosophy, 2007 Dissertation directed by: Professor Min Wu Department of Electrical and Computer Engineering A critical and challenging aspect of visual communication technologies is to immunize visual information to transmission errors. In order to effectively protect visual content against tra...
متن کاملVideo transmission over mobile satellite systems
Mobile satellite communication channels are characterized by long transmission delays, variation of these delays, high bit-error-rates, shadowing and the multipath e!ect which severely reduce the quality of video services. Error control techniques including feedback mechanisms, error concealment methods, forward error correction techniques and error resilience schemes are examined in this paper...
متن کاملA Novel Temporal-Frequency Domain Error Concealment Method for Motion Jpeg
Motion-JPEG is a common video format for compression of motion images with highquality using JPEG standard for each frame of the video. During transmission through a noisychannel some blocks of data are lost or corrupted, and the quality of decompression frames decreased.In this paper, for reconstruction of these blocks, several temporal-domain, spatial-domain, andfrequency-domain error conceal...
متن کاملA joint encoder-decoder error control framework for stereoscopic video coding
Stereoscopic video coding (SSVC) plays an important role in various 3D video applications. In SSVC, robust stereoscopic video transmission over error-prone networks is still a challenge problem to be solved. In this paper, we propose a joint encoder–decoder error control framework for SSVC, where error-resilient source coding, transmission network conditions, and error concealment scheme are jo...
