Application of map - ca in video frequency compression 在视频压缩中的应用
May and 4 groups video frequencies compressions card mix use 可以与4路视频压缩卡混合使用。
Audio frequency and video frequency compression technology , real - time data transmission technology and network technology make it impossible to achieve multimedia communication on ip network 音频和视频压缩技术、实时数据传输技术及网络技术的成熟,使得在ip网络上实现多媒体通信成为可能。
After the image lifting wavelet transformation , its coefficients have some characteristics , for example : the frequency compression characteristic , namely the primitive image energy majority of gathers to the low frequency sub - belt ; spatial compression characteristic , namely high frequency sub - belt energy majority of centralisms in primitive corresponding and so on image edge , outline position ; the coefficient distribution similarity , namely in the 经提升小波变换后,其系数具有如下特性:频率压缩特性,即原始图像的能量大部分聚集到低频子带;空间压缩特性,即高频子带的能量大部分集中在原始图像的边缘、轮廓等对应的位置;系数分布相似性,即同一方向上各级子带系数幅值分布大体一致。
At first , this article briefly introduces streaming media technology and transmission method , streaming media document , video frequency compression technology and the composition of streaming media system , in detail expounds the transmission principle of streaming media technology , and on base of experiment analyze and compare the current three solution projects of the video and audio technology , expound emphasis on the character of the modem distance education and the present condition of distance edution in chinese and american , and compare and on base of this analyzes the modern distance education of chinese and american , summarize the exsisting questions of our modern distance education 本文简要介绍了流媒体技术及传输方法,流媒体文件及视频压缩技术和流媒体系统的组成,详细阐述了流媒体技术的传输原理,并通过实验分析比较现存的三种网上视音频技术解决方案,重点阐述了现代远程教育的特征及目前中美现代远程教育的现状,并在此基础上对中美两国现代远程教育进行了比较与分析,总结出我国现代远程教育存在的问题。
