高速数字式摄像机的控制与数据流远距离传输的研究

The Study of High-Speed Digital Camera Control and Data-Stream Long-Wire Transmission

在实时处理高速数字摄像机的数字视频信号时 ,通常要求数据传输通道具有很高的带宽和有效的传输距离以及正确的外部触发控制。因此在设计和构建这些高速率的数据传输通道时 ,不但要选择合理的传输形式 ,而且要对数据的编码、解码、驱动、接口等电路进行认真的研究 ,以达到最佳的配合。

Very high data bandwidth and valid transmission distance and right trigger mode were demanded in real-time and high-speed digital camera data transmission channel. Not only reasonable transmission mode was chosen but also the circuits of coding and decoding and driving and interface must be deeply studied when these high -speed data channels were studied and constructed. The transmission technique of difference relay in the paper may be widely apply in long wire transmission of enormous data .
