Abstract

An SDDI signal in accordance with an AV signal is selectively recorded in an MO disc 6 of a portable AV editing apparatus 1 from a hybrid recorder 20 provided with an on-line editing function. The user carries the portable AV editing apparatus 1 around separate from the hybrid recorder 20 and uses the SDDI signal recorded in the MO disc 6 to perform off-line editing and prepare an EDL (edit decision list). This EDL is transmitted from the field to the station. The EDL is used for on-line editing at the station.

Claims

1. A system for editing a video signal, comprising:

a recording/on-line editing device for recording said video signal on a recording medium, and for selectively performing an on-line editing operation on said video signal reproduced from said recording medium; and

a portable editing device including an interface circuit for selectively connecting said recording/on-line editing device to said portable editing device for providing communication therebetween, including a storage medium for storing said video signal received from said recording/on-line editing device, including a display having a first, a second and a third display portion for displaying said video signal received from said recording/on-line editing device, including an input unit for manipulating said video signal displayed on said display, and including a programmable processor for controlling editing operations;

wherein said portable editing device is operative to record said video signal on said storage medium when said portable editing device is selectively connected to said recording/on-line editing device that performs said on-line editing operation such that a first display portion shows said video signal represented by picture units while receiving said video signal from said recording/on-line editing device, such that a second display portion shows a first picture and a last picture selected from a group of pictures displayed in said first display portion as designated by said input unit, and such that a third display portion shows said group of pictures after said on-line editing operation as controlled by said programmable processor; and

wherein when said portable editing device is not connected to said recording/on-line editing device, said portable editing device is operative to perform an off-line editing operation on the reproduced video signal that has been previously transferred to said storage means.

2. The system according to claim 1, further comprising an encoder for compression encoding said video signal, and wherein said interface circuit inputs said video signal selected from a plurality of video signals recorded by said recording/on-line editing device on said recording medium.

3. The system according to claim 1, wherein said input unit is operative to select said picture units by a manual mode using a search dial or by an automatic mode using an automatic selection at predetermined time intervals.

4. The system according to claim 1, wherein said interface circuit inputs said video signal as image fields such that said storage medium stores said video signal on an image-by-image basis.

5. The system according to claim 1, wherein said storage medium is a magneto-optic disc.

6. The system according to claim 1, wherein said video signal includes an audio signal.
