Robust Video Transmission over Binary Symmetric Channels with Packet Erasures
نویسندگان
چکیده
A video transmission system is presented based on the 3-D SPIHT algorithm for video compression and turbo codes for channel error protection. The channel considered is a binary symmetric channel with packet erasures, used for modeling the concatenation of a congested wired link followed by a noisy wireless hop. Unequal error protection with turbo codes is used for providing strong channel protection, with rate allocation performed by a Viterbi-based algorithm. The received video quality degrades gracefully in the presence of channel errors.

A 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 Transmission of JPEG2000 Codestreams over Packet Erasure Channels
In this paper, a robust image transmission scheme based on JPEG2000 is proposed for packet erasure channels. Error resilience functionalities provided by JPEG2000 are utilized to control the source coding efficiency and the robustness according to channel conditions. Furthermore, together with the proposed interleaving scheme, some erasures can be recovered. Experimental results show the effect...
متن کاملSpatially-Coupled LDPC Codes for Transmission over Nonergodic Channels: Recent Advances
This paper resumes our recent advances in the analysis and design of Spatially-Coupled LDPC (SC-LDPC) codes, used for transmission over nonergodic channels, in particular over the block-fading channel and over the block erasure channel. It has been shown that: a) SC-LDPC codes are naturally suitable for nonergodic channel transmission and are robust to packet errors/erasures; b) it is possible ...
متن کاملBinary Erasure Codes for Packet Transmission Subject to Correlated Erasures
We design some simple binary codes that are very well suited to reconstruct erased packets over a transmission medium that is characterized by correlation between subsequent erasures. We demonstrate the effectiveness of these codes for the transmission of video packets for HDTV over a DSL connection.
متن کاملA Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding
Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...
