AVS.rar - AVS视频编码标准PPT,介绍了AVS的关键技术,并呵H.264和MPEG4做了一些比较。,2007-10-19 15:27:55,下载183次
ABS.RAR - Abstract—Mobile devices performing video coding and streaming over wireless and pervasive communication networks are limited in energy supply. To prolong the operational lifetime of these devices, an embedded video encoding system should be able to adjust its computational complexity and energy consumption as demanded by the situation and its environment.,2007-10-17 16:10:02,下载8次
AssemToolsGuide.rar - TI warrants performance of its products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are utilized to the extent TI deems necessary to support this warranty. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements.,2007-10-17 16:06:57,下载1次
tms320dm642.rar - The TMS320C64x™ DSPs (including the TMS320DM642 device) are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The TMS320DM642 (DM642) device is based on the second-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture (VelociTI.2™ ) developed by Texas Instruments (TI), making these DSPs an excellent choice for digital media applications. The C64x™ is a code-compatible member of the C6000™ DSP platform.,2007-10-17 16:05:04,下载33次
AVS.RAR - 文章比较了H.264和AVS两个标准在运动补偿中运动矢量预测算法的差别, 提出了一种实现H.264 中 主档次(main pmille)下的第4级别(1evel 4)和AVS中的基准档次面向高清应用时运动矢量预测复用的硬件结构。 提出了一种新颖的缓存管理更新机制.极限情况下用于运动矢量的片上缓存大小减少了75% 。用FPGA验证结果 表明资源占用情况是单独实现AVS的2.3倍,是单独同时实现两个标准的70%。能实现对1080i 30Hz高清图像实 时解码。,2007-10-17 16:02:00,下载57次
mpeg.rar - 本文首先介绍了视频处理的一般原理,主要介绍了采样,变换编码,预测编码,量化,熵编码等。然后介绍了最新的视频标准MPEG主要介绍了系统体系结构,系统解码器模型,缓冲区模型规范,对象描述框架,以及场景描述和视频部分。接着介绍了DSP,介绍了它的特点,主要应用,CPU结构,,2007-10-17 15:59:42,下载26次
MOBILE.RAR - 视频序列运动矢量分布的中心偏移特性在运动估计中发挥重要的作用,但忽视了运动矢量分布的方向性。该文提出了非对称双十字形搜索(UDCS)算法,给出了在搜索的初始阶段使用小十字搜索模型对小的运动矢量搜索并在相继的搜索过程中使用具有方向性的十字形搜索模型对大运动矢量进行搜索的步聚。介绍了该算法的实现结构,并分析了该算法搜索性能。,2007-10-16 09:39:41,下载21次
