Design of the pseudocolor coding - plate 假彩色编码板的设计
The interface of the board can be connected to encoder board conveniently 接口板的4个接口可以方便地与4个编码板连接。
This driver module includes implementation of addressing encoder end ’ s internal register , reading encoded data from the encoder end and the interrupt handler of the encoder end 整个驱动模块实现了对编码端内部各寄存器的访问,从编码板读取编码数据和预览数据,以及编码系统中断处理程序等功能。
The is offers robustness neceesary for noisy channels . the video coding system discussed in this part can transform the pal video signal to mpeg - 2 ts . it offers an effective method for video signal transmitting 本文研制的mpeg - 2编码板可以将pal制视频信号压缩为mpeg - 2传输流,为电视信号的传输提供了一种有效的途径。
Each encoder board can encode 4 ways of video and consists of 4 pieces of tw9903 , used to implement analog video ’ s a / d transformation , 1 piece of aq424 , used to combine four ways of digital video into one , 1 pieces of ime6400 , used to encode digital video into mpeg - 4 code 每个编码板采用4个tw9903实现4路模拟视频的a / d转换, 1个aq424实现数字视频的四路合成, 1个ime6400实现数字视频的mpeg - 4压缩编码,从而实现4路视频编码。
