Video editing apparatus
First Claim
1. Video editing apparatus for use with video playback and recording devices wherein information signals on a first record medium are reproduced and recorded on a second record medium, the relative positions of said first and second record media being represented by position data signals, said apparatus comprising means connectable to said video playback and recording devices to provide reord medium position data derived from said position data signals;
- a console having a plurality of display registers for displaying said record medium position data;
a plurality of register selector means associated with corresponding ones of said display registers, each being operable to select its associated display register;
a plurality of signal selector means operable to select respective information signals reproduced from said first medium to be recorded on said second medium when a selected one of said media reaches a position represented by the position data displayed in a selected display register;
a plurality of indicator means associated with respective ones of said signal selector means and operative to provide predetermined indications to apprise an operator of the relative times at which said respective information signals are to be recorded on said second medium;
central processing means responsive to the operation of a selected signal selector means and a selected register selector means for associating the information signal selected by that signal selector means with the position data displayed in the display register corresponding to said operated register selector means, and for initiating the recording on said second medium of the information signal selected by that signal selector means when said selected medium reaches the position represented by the associated position data; and
means for communicating between said console and said central processing means.

Abstract
Video editing apparatus for use with video playback and recording devices, such as video tape recorders (VTR'"'"'s) wherein signals are reproduced from a first record medium and recorded on a second record medium. The apparatus is provided with a console having a plurality of display registers for displaying record medium position data representing respective positions of the first and second media. Register selector switches are associated with respective ones of the display registers, each such switch being operable to select its associated display register. The console also is provided with a plurality of signal selector switches, each being operable to select a particular type of signal (such as a video or audio signal) reproduced from the first medium to be recorded on the second medium when a pre-selected one of the media reaches a position represented by the position data displayed in a selected display register. Indicators, such as visual indicator devices, are associated with respective ones of the signal selector switches and are operative to apprise an operator of the relative positions at which the particular types of signals are to be recorded on the second medium. The apparatus also is provided with a central processing unit responsive to the operation of a selected signal selector switch and a selected register selector switch for associating the position data displayed in the display register associated with that register selector switch with the selected signal selector switch, whereby when the pre-selected medium reaches the position represented by the associated position data, the particular type of signal selected by the signal selector switch is recorded on the second medium.
