视频

Video Web site as complementary to TV Media,has its own advantages, especially in the economic environment is not optimistic at the time, of course, brand advertisers will not abandon the television media, but more consideration will be given to interactive TV and video combination of goal of covering as much as possible the effects of users.

视频网站作为电视媒体的互补，有其自身的优势，尤其是在经济大环境不乐观时，品牌广告主当然不会放弃电视媒体，但会更多的考虑将电视与视频互动相结合，实现对目标用户尽可能覆盖的效果。

Interactive video art is a important direction of media art.

互动视频艺术属于新媒体艺术的范畴，它是集视频和交互手段于一身的新的艺术表现形式。

Since its introduction in 1997, DVD-Video has become the fastest-growing format of choice for distributed interactive video content.

至从它于1997被引进， DVD-视频成为增长最快的分布式互动视频内容所选择的格式。

With the rapid development of Internet network, wireless communication, and interactive multimedia, video compression is becoming an important issue in the research area of video communication today.

随着 Internet 网络、无线通信技术以及交互式多媒体的迅速发展，视频压缩成为了当今视频通信的研究重点。

Deinterlacing is not only needed for efficient block-based video processing, but also for displaying interlaced video in progressive format.

去隔行不仅仅是高效率的、基于块的视频处理所需要的，而且也是在逐行扫描格式中显示隔行视频所必需的（例如在一个 LCD 平板上）。

It has effective interlaced signal encode algorithm and wide bit rate scope. MPEG2 can represent interlaced and progressive video sequence, and it is widely used in DVD, HDTV and digital satellite TV.

MPEG2是视频和音频信号数据压缩国际标准MPEG1的扩展，直接面向高数据率的广播格式，提供了有效的隔行视频信号编／解码算法，支持宽范围的比特率。

As a compatible extension ,MPEG-2 video builds upon the completed MPEG-1 standard by supporting interlaced video formats and a number of other advanced features,including those to support

作为一种兼容扩展，MPEG-2视频建立在MPEG-1标准之上，支持交错视频格式及大量先进性，包括HDTV。

The Baseline Profile supports intra and inter-coding (using I-slices and P-slices) and entropy coding with context-adaptive variable-length codes. The Main Profile includes support for interlaced video, inter-coding using B-slices, inter coding using weighted prediction and entropy coding using context-based arithmetic coding. The Extended Profile does not support interlaced video or CABAC but adds modes to enable efficient switching between coded bitstreams (SP- and SI-slices) and improved error resilience.

基本档次支持帧内和帧间编码及自适应上下文变长编码的熵编码；主要档次支持交替视频，使用B条带的帧间编码，使用加权预测的帧间编码，使用基于上下文的算术编码的熵编码；扩展档次不支持交替视频或CABAC熵编码，但增加了一种模式允许有效的交换编码的位流，即SI、SP帧，并改进了错误恢复机制。

The difference between video frequency integration and intermediate integration is presented, and the effect of video frequency integration is analyzed. The obtained conclusion is significant to the actual project.

并讨论了视频积累和中频积累的差别，对视频积累的效果进行了详尽的分析，所得结论对实际工程有指导意义。

Nowadays, adaptive rate control is the basic and significant technique of video multicast systems in the Internet. These adaptation approaches are all designed based on the best-effort service that today's Internet can provide, they present two drawbacks—unsteadiness of video receiving quality and no consideration of intersession fairness.

当前，自适应速率控制是因特网中视频组播系统采用的一种最基本和最重要的技术，但现有的自适应机制都是基于因特网提供的尽力而为服务来设计的，它们具有如下两个缺陷，即视频接收质量的不稳定性和无法实现会话间资源共享的公平性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
