Abstract

An editing controller for video tape recorders has a return/jump key which enables an operator to check and quickly correct continuities of two takes for video images. The return/jump key functions to return the tape position to a cut-in point during preview operation, and to jump the tape position towards a cut-out during review operation.

Claims

1. An editing control apparatus for video tape recorders, comprising:

(A) means for sensing positions of video tapes installed in a recorder-VTR and a player VTR, respectively;

(B) means for memorizing data for positions of the video tapes obtained at said position sensing means;

(C) means for advancing video tapes of the recorder and player VTRs in synchronism to each other with reference to the memorized data for the respective video tapes;

(D) means for executing editing operations by recording video signals reproduced by said player-VTR on video tapes of said recorder-VTR from tape positions memorized in said data memorizing means;

(E) means for interrupting said video tape advancing operation by manually operating switching means;

(F) means for positioning respective video tapes to positions referenced by memorized data in said data memorizing means automatically and without manual intervention immediately after said interrupting means is actuated; and

(G) when said means for interrupting is actuated, said means for positioning including means for automatically moving the video tape of the recorder-VTR at high speed relative to normal playback speed to a predetermined position prior to a memorized position and means for then automatically advancing without further manual intervention the recorder-VTR video tape at the normal playback speed from said predetermined position to said memorized position.

2. An editing control apparatus for video tape recorders as claimed in claim 1, further comprising:

means for executing editing operations by recording video signals reproduced by said player-VTR on video tapes of said recorder-VTR from tape positions memorized in said data memorizing means, and

means for previewing an editing operation for a rehearsal purpose on a monitor screen, said interrupting means being operative after said memorized tape position has passed during said preview operation, and the respective tapes are automatically rewound to the memorized tape positions.

3. An editing control apparatus as claimed in claim 1, further comprising:

means for executing editing operations by recording video signals reproduced by said player-VTR on video tapes of said recorder-VTR from tape positions memorized in said data memorizing means, and

means for reviewing an editing program for confirmation purposes on a monitor screen by advancing said recorder-VTR, said memorized data including an edit-in point and an edit-out point, said interrupting means being operative after said edit-in point has passed during said review operation, and the video tape of the recorder-VTR being fast-forwarded to a position shortly before said edit-out point immediately after said interrupting means is actuated.

4. An editing control apparatus as claimed in claim 1, wherein said data memorizing means includes edit-point memory means and escape memory means associated with respective edit point memory means, and when the video tape is advanced across said memorized tape position, the data in said edit point memory means are reserved in said escape memory means.

5. An editing control apparatus as claimed in claim 4, wherein when said interrupting means is actuated, said escape memory means feeds back reserved data therein to said edit point memory means.
