Real - Time Video Compression Using Di erentialVector
نویسندگان
چکیده
|This paper describes hardware that has been built to compress video in real time using full-search vector quan-tization (VQ). This architecture implements a diierential-vector-quantization (DVQ) algorithm and features a special-purpose digital associative memory, the VAMPIRE chip, which has been fabricated in 2m CMOS. We describe the DVQ algorithm, its adaptations for sampled NTSC composite color video, and details of its hardware implementation. We conclude by presenting both numerical results and images drawn from real-time operation of the DVQ hardware .

Fast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard
three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...
متن کاملDesign of a Real - TimeVideo - Compression System
This paper describes a di erential-vector-quantization (DVQ) algorithm which has been developed for real-time compression of digital video images. In the rst part of the paper, we present the DVQ algorithm and discuss a number of experiments which were performed in order to insure that the algorithm is suitable for hardware implementation. We show that the DVQ algorithm performs comparably to s...

This paper presents the study of modifying a legacy single-issue DSP processor to provide real-time processing capacity for emerging multimedia applications. The latest video compression standards such as H.264 and SMTPE VC-1 require both high computing performance and flexibility which can not be met by legacy single-issue DSPs. Feasibility of achieving both real-time performance and flexibili...

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...
متن کاملA Real-time Software Decoder for Scalable Video on Multi-processors
Increasing heterogeneity of future networks is likely to result in transmission links with widely di erent available bandwidths. Scalable video compression has been shown to be an e ective tool for video communication across these heterogeneous networks. For instance, the scalable algorithm described in [2, 3] can generate one embedded bit stream with tens of available bit rates ranging from te...
