Special Section on the Joint Call for Proposals on High Efficiency Video Coding (HEVC) Standardization
Special Section on the Joint Call for Proposals on High Efficiency Video Coding (HEVC) Standardization THE FIRST commercially successful digital video compression standard emerged 20 years ago in the form of Recommendation ITU-T H.261. MPEG-1 and H.262/MPEG2 video (the latter was jointly standardized by ITU-T and ISO/IEC) were then developed very soon thereafter, and they resulted in an explosi...
متن کاملMpeg-4 High-efficiency Aac Coding
The name MPEG-4 High-Efficiency AAC (HE-AAC) refers to a family of recent audio coders that were developed by the ISO/IEC Moving Picture Experts Group (MPEG) by subsequent extension of the established Advanced Audio Coding (AAC) architecture. These algorithmic extensions facilitate a significant increase in coding efficiency relative to previous standards and other known systems. Thus, they pro...
متن کاملCompressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard
Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
متن کاملFast coding unit decision method based on coding tree pruning for high efficiency video coding
A fast coding unit (CU) decision method is proposed for high efficiency video coding (HEVC) by determining early the CU sizes based on coding tree pruning. One of the most effective, a newly introduced concept in HEVC, is variable CU size. In determining the best CU size, the reference encoder of the HEVC tests every possible CU size in order to estimate the coding performance of each CU define...
متن کاملAnalysis of Residual data for High Efficiency Video Coding (HEVC)
In this paper, we propose an analysis of the residual information of the HEVC. We focus specifically on analyzing the coding of the DC coefficient and its effect on bit consumption. We investigate on the possibilities and the limits of coding the DC coefficient, in a lossless coding way, by changing the process to the encoding a spatial translation value or the residual blocks instead of the tr...
