标准视频 meaning in Chinese
normal video
Examples
- The itu656 video format is a popular standard in the market of video products , so it is very important to decode it
Itu656标准视频格式是全世界普遍通用的视频接口,对它的解码尤为重要。 - Sending images over the network once the system is in place , users can start transmitting images over the network via high - quality video imaging standards such as motion jpeg and mpeg
在网络上传送图像，一旦系统安装好后，使用者可以通过网络传高质量的标准视频图像诸如jpeg格式以及mpeg格式。 - For the third type , the blood ' s speed is very fast in a frame and maybe very slow in the next frame . it is difficult to measure the velocity using a standard video system but can be measured with high - speed video camera system [ 17 , 42 , 43 ]
第三类微血管内血液流动特性是时快时慢，很难在标准视频设备下测量出来，但如果在高速采集卡下的视频图象和第一类一样时，可以用第一类相同的方法测量出来。 - Meanwhile , with the intercross and penetration of different knowledge , wavelet theory has applied to many other fields successfully . for example , in the video coding , with the multiresolutional nature of wavelet analysis , three dimensional wavelet video coding has been shown to be competitive with standard coders . although 3 - d wavelet video coder usually require a larger buffer and incur a longer delay than standard coders , an important feature of the 3 - d wavelet approach is the support of scalabilities in the compressed video
同时，随着各门学科间的相互交叉与渗透，使得小波理论成功地在许多领域得到了广泛的应用。例如，在视频方面，由于小波本身的多分辨率的数据结构为支持可伸缩编码提供了一个良好条件，所以与标准视频编码相比，小波编码方法具有更大的发展前景。 - The image data are stored and exchanged under an " interruption & dma " parallel mechanism , which can run simultaneously with dsp unit . two different voltage power resources are provided for the whole system , which are watched by one surveillance circuit . system anti - jamming and system optimization measures are added into system for future circuit debug
视频采集单元采用philipssaa7111及fpga芯片，以标准视频信号( pal或ntsc )为输入，通过fpga及i2c总线，对图像数据进行剪裁及采集；采用两帧存储体轮换工作机制，省去fifo器件，降低成本；采用"交叉连续"地址存储空间，便于dsp进行dma传输。
