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
作為工程實現前的實驗研究，對三類具有ieee1394介面的數字錄像機和攝像機進行了視頻圖像傳輸實驗，發現無壓縮格式的按ieee1394標準傳輸的數字視頻圖像（傳輸距離從4 . 5米到100米之間） ，較原始模擬視頻圖像在幾何位置信息上沒有衰變，而在亮度、對比度、邊緣清晰度這些方面有明顯的優勢；但是按dvcam壓縮格式（常見于sony公司的系列產品，是5 ： 1的dct幀內壓縮）壓縮的數字視頻圖像，較原始模擬參照圖像有明顯的幾何畸變。 -
