VTR Preview System Connected by LAN with Upper System

Abstract

Lately, the personal computers(PC) of inexpensive and high-powered has been introduced to TV stations, so the managements in any sections, like in program producing and the program datas, and the business infomation, the operation has been systemaized. This report is the example. Before broadcasting the recorded programs, previewing the tape is necessary, to clock the time between commercials and also, to check the quality of the picture and the sound. This time we have developed the preview system with PC to operate above with high efficiency. And we have connected this system and the upper system with LAN to preserve the preview datas and to acquire the program information, so the reliability of the data has been improved. Also, the communication between PC and the VTR is serial, the direct connection without using the VTR interface made the construction of the machinery very simple.
