Abstract

PURPOSE:To grasp the outline of a master tape in a short period by providing a memory storing a picture data by one picture and a time code as to each in point of plural work tapes recorded on an on-line master tape. CONSTITUTION:A video signal of work tapes 7, 8, 9 reproduced by a VTR 1 is fed to a signal processing circuit 3 and recorded on an on-line master tape 6. A write signal is generated from a timing control circuit 4 to a memory 5 at that time and one picture signal of only in points E, F, G at assembling from the circuit 3 via a switch SW controlled by the circuit 4 is written in the memory 5 as a still picture. At the insert of the work tape 10, a picture at an in point H is written in the memory 5 and a picture of in point F written before is rewritten into a picture of an in point I. After the end of generating a tape 6, an optional address is designated from the circuit 4 to read the information of the tape 6 written in the memory 5 and displayed on a monitor 12 in terms of a multipicture or the like and the outline of the tape 6 is grasped in a short period.

Description

第３図）。In the above configuration, the video signals of each work tape (for example, 7.8.9 in FIG. 2) played back by the VTR 1 are sent to the signal processing circuit 3 and recorded on the offline master tape 6. At this time, a write signal is generated from the timing control circuit 4 to the memory 5, and is sent from the signal processing circuit 3 to the in point (for example, E, F in FIG. 2) during assembly via the switch SW controlled by the timing control circuit 4. , G) is written to the memory 5 as a still image (
Figure 3).

第２図のワークテープ１０のインサート時は、第４図の
