Abstract

When, during the replay of the VTR, time codes are sent to the control unit and the special part detection device supplies detection data to the control unit, the control section displays an indication of the special parts being detected and the time codes found and transferred at detection time on the display device and the video monitor, and writes the detection data and the corresponding time codes into the memory. Hence, the contents of the special parts detected in the reproduced video (tape scratch, flicker, special pattern, or change in average luminance, and the levels of these) and the time codes found and transferred at detection time are stored, thus enhancing the efficiency of the editing of cutting off the special parts.

Claims

1. A video reproduction controller comprising:

an input means for inputting, from a video reproducing device, a position information about a recording medium when a special part is detected by reproducing a video information of a recorded video for producing a broadcasting program on said recording medium of said video reproducing device for editing said recorded video, said special part comprising flickers and/or an image having an entire image area which includes a specified image area, a ratio of the specified image area to the entire image area being beyond a first predetermined value, the specified image area being that portion of the entire image area having contrast and frequency range of spatial frequency peak value beyond a second predetermined value;

a storage means for storing said position information;

a display means for retrieving said position information from said storage means and displaying position where said special part detected is recorded on said recording medium;

a specification means for specifying from outside replay position on said recording medium; and

a control means for generating control signals to control replaying of said video reproducing device based on said position information corresponding to said specified replay position.

2. A video reproduction controller according to claim 1, wherein said input means further inputs detection data on said special part of said video information, said storage means further stores said detection data, and said display means further displays a content of said special part detected based on said detection data.

3. A video reproduction controller according to claim 1, further comprising:

a video storage means for inputting said video information on said recording medium replayed by said video reproducing device and storing said video information as digital data; and

a read means for retrieving said digital data from said video storage means based on said position information corresponding to said replay position specified by said specification means and performing control to reproduce desired position of said video information.

4. A video reproduction controller according to claim 1, further comprising:

a detection means for detecting said special part from said video information reproduced by said video reproducing device;

wherein said input means inputs, when said detection means detects said special part and outputs said detection data, said position information on said recording medium from said video reproducing device, or said detection data from said detection means.

5. A video reproduction controller according to claim 4, wherein said detection means detects a special pattern in said video information as said special part.

6. A video reproduction controller according to claim 4, wherein said detection means detects a flicker in said video information as said special part.

7. A video reproduction controller according to claim 4, wherein said detection means detects a change of average luminance in said video information as said special part.

8. A video reproduction controller according to claim 5, further comprising a means for outputting, to outside, display data to display said position on said recording medium where said special part is recorded and alternate display data to display said content of said special part based on said detection data.

9. A video reproduction controller according to claim 1, wherein said position information from said video reproducing device is a time code recorded on said recording medium.

10. A video reproduction controller according to claim 1, wherein said position information from said video reproducing device is a count information output by said video reproducing device as said recording medium is moved, and said count information represents a position relative to a start position of said recording medium.

11. A video reproduction controller according to claim 1, wherein said position information from said video reproducing device is a control information recorded on said recording medium for controlling a movement of said recording medium and output by said video reproducing device.

12. A video reproduction controller according to claim 1, further comprising:

a means for inputting said video information from said video reproducing device and outputting said video information to a video recording device; and

a means for controlling said video recording device, based on said position information, to record said video information.

13. A storage medium removably loaded into a video reproduction controller and adapted to store a position information about a recording medium, in a predetermined format, when a special part is detected by reproducing a video information of a recorded video for producing a broadcasting program on said recording medium of said video reproducing device for editing said recorded video, said special part comprising flickers and/or an image having an entire image area which includes a specified image area, a ratio of the specified image area to th entire image area being beyond a first predetermined value, the specified image area being that portion of the entire image area having contrast and frequency range of spatial frequency peak value beyond a second predetermined value.

14. A storage medium according to claim 13 further storing detection data representing said special part of said video information in addition to said position information.

15. A storage medium according to claim 13, wherein said special part is a special pattern detected of said video information.

16. A storage medium according to claim 13, wherein said special part is a flicker detected of said video information.

17. A storage medium according to claim 13, wherein said special part is a change in average luminance detected of said video information.

18. A storage medium according to claim 13, wherein said position information from said video reproducing device is a time code recorded on said recording medium.

19. A storage medium according to claim 13, wherein said position information from said video reproducing device is a count information output by said video reproducing device as said recording medium is moved, and said count information represents a position relative to a start position of said recording medium.

20. A storage medium according to claim 13, wherein said position information from said video reproducing device is a control information recorded on said recording medium for controlling a movement of said recording medium and output by said video reproducing device.
