视频信号

The principles, commonly used methods and criteria of data compression are introduced descriptively.

数字化多媒体信息尤其是数字视频、音频信号的数据量是极其庞大的，给存储、传输以及有效、快速获取信息都带来了严重的障碍，如果不对其进行有效的压缩就难以得到实际应用〔'。

The ISL34340 is a serializer/deserializer of LVCMOS parallel video data.

Intersil公司的ISL34340是LVCMOS并行视频数据的串并/并串转换器，能在单一差分对上传输24位RGB信号。

And the high-speed digital signal processor and very large scale integration make the possibilities of video compression and transmission.

而高速数字信号处理技术和超大规模集成电路技术的发展使实时的视频压缩和传输成为可能。

Images can be generated by video digitizer cards that capture NTSC analog signals and create a digital image.

用视频数字化卡可以捕获NTSC制式或PAL制式的电视模拟信号并生成数字图像。

The principle of superposition and the implementation of the method as well as the analysis of measurement error are discussed.

基于比较法的应用中所出现的像的信息被掩埋的问题作者提出用叠加法处理视频输出信号，在第五章中论述了叠加法的原理和实现以及用于测量时的误差分析。

When connected to a camera that has been reset, there are no previous timing pulses to synchronize to and the frame grabber needs to be driven by separate timing signals to enable it to interpret the incoming video.

当连接到重置过的相机上时，无法被原来的时序脉冲同步化而需要单独的时序信号驱动，这样的帧捕获才能中断输入视频。
