System for recording/reproducing video data on or from a tape medium for storing digital signals and method therein

TLDR: In this article, a technique whereby digital video signals can be recorded or reproduced on or from a magnetic tape was disclosed, where the first controller converts analog video data into digital to store them in a memory, or reproduce said stored data by converting them into analog of real-time, a different input of the key is checked by the second controller to store said video signals into the tape.

Abstract: There is disclosed a technique whereby digital video signals can be recorded or reproduced on or from a magnetic tape. Using second controller to control a system such as a DAT recorder employing a digital signal processor, and first coutroller for converting said video signals into analog or digital, the video data are processed as in the conventional method of processing audio data according to the input of the mode selecting key. By the input of the key, the first controller converts analog video data into digital to store them in a memory, or reproduce said stored data by converting them into analog of real time, a different input of the key is checked by the second controller to store said video data into the tape. When storing said video data into the tape, the video signals are stored, imparted with synchronizing pulse to be distinguished from audio signals, and when reproducing said signals from the tape, the synchronizing pulse is detected to store only the video data into the memory, which data are reproduced by the first controller.
