广播数字视频磁带记录仪.记录和复制错误识别方法 - According to the characteristic of ieee 1394 with wide bandwidth , common and real - time , the author put forward ieee 13 94 should be applied into real - time digital video transfer in optics - electronics theodolite . before engineering realization , carried out a video image transfer test on three types of digital video tape recorders and camera with ieee 1394 interface . we found that digital videos without compression transfered under ieee 1394 standard ( transfer from 4 . 5m to 100m ) , compared with analog videos , have no geometric distortion , and have better luminance , contrast , definition
作为工程实现前的实验研究，对三类具有ieee1394接口的数字录像机和摄像机进行了视频图像传输实验，发现无压缩格式的按ieee1394标准传输的数字视频图像(传输距离从4 . 5米到100米之间) ，较原始模拟视频图像在几何位置信息上没有衰变，而在亮度、对比度、边缘清晰度这些方面有明显的优势；但是按dvcam压缩格式(常见于sony公司的系列产品，是5 ： 1的dct帧内压缩)压缩的数字视频图像，较原始模拟参照图像有明显的几何畸变。
