标准视频信号 meaning in English

video standard signal

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。
The dh - pci - h black and white grabber finishes the process of transmitting the data , which controlled by the grabber . without cpu , its speeds of which be transmitted be at 40mb / s , and be able to connected with the more parts of the standard or un - standard signals of videos , so it is finished at the data is transmitted in real - time
采用dh - pci - h黑白图像采集卡，数据的传送过程是由图像卡控制的，无需cpu参与，图像传输速度可达40mb s ，能够与绝大部分的标准与非标准视频信号相连接，实现了数据的实时传输。
