Resilient Video Coding for Noisy Channels
نویسنده
چکیده
In this tutorial paper, we consider the effect of errors in compressed video data, and discuss both standard and more novel techniques for increasing error resilience. We consider the performance of block based coding schemes such as MPEG1, MPEG2, and h.26x when transmitted over noisy channels, a subject of relevance to digital terrestrial television, video communication, mobile digital video, and video storage.

متن کاملA New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
متن کاملRobust layered coding of video for transmission over noisy channels
A novel robust scheme is presented, for the efficient transmission of image sequences over unreliable channels. The proposed scheme is based on an efficient error-resilient wavelet video coder and is able to produce embedded bitstreams. The robust coder is evaluated for the transmission of image sequences over binary symmetric channels and is shown to have very promising performance.
متن کاملA data embedding scheme for H.263 compatible video coding
We propose a novel data embedding scheme for H.263 video coding. The proposed method, which can protect important information such as picture header and motion vector, is specifically suitable to noisy and bandwidth limited channels such as in wireless communications. The method can exactly recover the motion vectors of corrupted macroblocks, therefore has better performance than other error re...
متن کاملTransmission of images over noisy channels using error-resilient wavelet coding and forward error correction
A novel embedded wavelet coding scheme is proposed for the transmission of images over unreliable channels. The proposed scheme is based on the partitioning of information into a number of layers which can be decoded independently provided that some important and highly protected information is initially errorlessly transmitted to the decoder. Forward error correction is used in conjunction wit...
