Video information editing system for providing video data in a controlled format
First Claim
1. A video information editing system for providing the video data produced on a video tape by a video tape recorder/playback device in a controlled format to permit selective viewing of the video data as graphically displayed on a video monitor upon playback thereof, said video information editing system comprising:
- a video tape recorder/playback device including video head means and adapted to contain a video tape;
field memory means having memory storage for storing at least one frame of video data, said field memory means being operably connected to said video tape recorder/playback device;
video data write means connected to the output of said video tape recorder/playback device for accepting analog video data from a video tape upon reproduction thereof;
analog-digital converter means interposed between said video data write means and said field memory means for converting analog video data from the output of said video data write means into digital video data for input to said field memory means;
memory control means connected between said video data write means and said field memory means for regulating the writing of video data from said video data write means into said field memory means;
interface means operably connected to said field memory means and to said video tape recorder/playback device, said interface means being adapted to be connected to external memory means to control the writing of digital video data from said field memory means into the external memory means and from the external memory means into said field memory means; and
digital-analog converter means connected to the output of said field memory means to convert the digital video data output therefrom into analog video data for input to a video monitor for graphic display thereof.

Abstract
A video information editing system has a field memory portion capable of storing predetermined units of digital video information, a peripheral circuit portion to make this field memory portion operate, and a video data writing circuit to rewrite video information from the field memory portion, these being added to a known video information reproducing device in the form of a video tape recorder/playback device. The system is so constructed as to access only specific video information comprising a portion of the complete original video information contained on the recording tape of the video tape recorder/playback device.
