视频带宽

The basic video bandwidth required to transmit luminance and chrominance signals is 4/2 MHz for the NTSC standard.

NTSC标准中亮度信号和色度信号传输所要求的基本视频带宽是4.2MHz。

As a result, by subsampling these chroma values, video standards and compression algorithms can achieve large savings in video bandwidth.

于是，通过对这些色度值进行子采样的方法，视频标准和压缩算法可以大幅度缩减视频带宽。

It is also possible to set auto range operation only one or two out of resolution bandwidth, video bandwidth and sweep time.

它也有可能设定自动的远程作战只有一个或两个号决议的带宽，视频带宽和扫描时间。

IN HDTV, the basic video bandwidth is at least twice of the conventional standard.

而HDTV的视频带宽至少要是常规标准的两倍。

This might lead to the impression that a wider video bandwidth is always preferable to a narrower one, but that is not the case.

这将会导致宽的视频带宽总是比窄的要好的印象，但事实并非如此。

Because of this, the instrument's video bandwidth is an important characteristic when peak detection measurements are required.

功率计只对信号的包络产生响应，为此功率计的视频带宽对于峰值测量是非常重要的。

Video output is proportional to Q whereas video bandwidth is inversely proportional.

视频输出正比于Q，而视频带宽成反比。

So, depending on the band- width required to serve the video and the bandwidth available, it creates a buffer to hold enough video so that it can start playing back the video while it is downloading video to the buffer in the background.

它决定于播放视频需要的带宽和可以带宽，它创建一个缓冲区来保持足够的视频数据，因此它可以在后台线程下载视频到缓冲区的同时播放视频内容。

This paper summarizes all kinds of the bandwidth smoothing algorithms for prerecorded VBR video ,compares the performances of these algorithms ,induces and formalizes these smoothing models,and gives the generalization description of them.

文章综述了存储 VBR视频带宽平滑的各种算法，比较了这些算法的各自特点，归纳、形式化了这些算法模型的更一般化表示。

Table 1 lists recommended video bandwidths for different wireless standards.

表1列出了对于不同无线标准推荐的视频带宽。

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。
