Standard-Compliant Enhancements of JVT Coded Video for Transmission over Fixed and Wireless IP
نویسندگان
چکیده
This paper describes standard compliant enhancements of the currently developed JVT coding algorithms for transmission over fixed and wireless IP-based networks. This includes a description of JVT coding algorithm and the adaptation to IP-based networks. The error resilience features within the JVT coding algorithm are presented in greater detail. Standard compliant encoder and decoder enhancements as well as the exploitation of network information to improve the quality in packet lossy environments are presented. Pointers and references to well-known and successfully applied error resilience schemes in prior video coding standards are provided. Different schemes are compared and appropriate experimental results based on common test conditions are presented and discussed.

H.26L/JVT coding network abstraction layer and IP-based transport
The JVT/H.26L video coding scheme conceptually consists of a Video Coding Layer (VCL) responsible mainly for coding efficiency and a Network Abstraction Layer (NAL) that supports video specific transport features for a variety of networks. This paper describes the H.26L/JVT NAL in general, including the parameter set concept and the transport over packet-based and bit-stream oriented networks. ...
متن کاملOptimized transmission of H.26L/JVT coded video over packet-lossy networks
Transmission of hybrid coded video including motion compensation and spatial prediction over error-prone channels results in the well-known problem of spatio-temporal error propagation at the decoder. A widely accepted standard-compliant technique to enhance the quality of the decoded video significantly is the more frequent introduction of intra-coded macroblocks. However, intra-coded informat...

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...
