2. Description of the Related Art Today, a disc reproducing apparatus, a video tape reproducing apparatus, or an audio apparatus for reproducing an image signal or an audio signal from an information signal recorded on an information recording medium such as an optical disk, a magneto-optical disk, a video tape, or an audio tape. Tape reproducing devices and the like have become widespread.

A signal reproducing apparatus for reproducing an image signal from an information signal recorded on the above information recording medium has an operation section for performing an operation for setting an operation mode of the signal reproducing apparatus. This operation unit has a "forward search" for searching an image to be viewed from the information recording medium mounted on the signal reproducing device.
Buttons, "backward search" button, "search" buttons such as "numeric keypad" for specifying the search position, "fast-forward" button for fast-forwarding images, and "fast-forward" button for fast-rewinding images Equipped with. This signal reproducing device causes a monitor such as a CRT to display an image corresponding to the operation mode set by the operation unit.

On the information recording medium, a plurality of information signals in which each information signal and the position of each information signal are associated with each other are recorded so as to be reproducible by the signal reproducing device.

For example, in a video disc, concentric or spiral tracks are formed on the main surface, the track is divided into a plurality of addresses, and an information signal associated with each address is recorded on the video disc. It is recorded so that it can be reproduced by the reproducing device. In this video disc reproducing apparatus, the address signal in which an address is associated with each information signal is associated with each position signal of each information signal in a one-to-one correspondence.

Further, the video tape is formed in the head scanning direction at the central portion of the video tape, and the audio track formed at one end side of the video tape in the tape running direction, the control track formed at the other end side. Video track. In this videotape, the audio track, control track,
Alternatively, an address signal is attached to a video track, and an audio signal of an audio track and an image signal of a video track are associated with each other for each address signal and recorded so as to be reproducible by a video tape reproducing device.

In an audio tape for a digital audio tape recorder (hereinafter referred to as DAT), for example, an audio signal and an address signal can be reproduced by an audio tape reproducing device for each frame of an audio track formed in the head scanning direction. It is recorded in.

As a method of displaying an image desired to be viewed on the monitor from the information recording medium mounted on the signal reproducing apparatus,
After specifying the index signal recorded at the desired image signal position on the information recording medium or the chapter signal recorded in advance for each frame from the operating unit, search for the index signal or chapter signal using the "Search" button. The first method is to specify the position information of the image you want to view using the operating unit, then the second method to search for the position information specified using the "Search" button. There is a third method in which the "fast-forward" button or the "fast-rewind" button of the operation unit is kept pressed until it is displayed.

In the second method, for example, when a video disk is used as the information recording medium, a second represented by hours, minutes, seconds, or one frame which is a finer unit (usually, in a signal reproducing device, A frame number with a minimum unit of displaying a screen of 30 frames per second) is designated by the operation unit. Further, when the information recording medium is a video tape, a real time code is designated by the operation unit. A search operation is performed using the designated time, frame number, or real-time code as position information.

By selecting an appropriate method from the respective methods and operating the operation section, the desired image signal is reproduced from the information recording medium mounted on the signal reproducing apparatus, and the image signal is reproduced from the reproduced image signal. Can be displayed on the monitor.

In the first method, however, there is a problem that it is not easy to use unless a sufficient number of index signals or chapter signals are recorded on the information recording medium. Further, it is impossible to perform a search operation on a screen on which the index signal or the chapter signal is not recorded, and there is a problem that the usability is poor. Further, there is a problem that the search operation is impossible when no index signal or chapter signal is recorded on the information recording medium.

The second method has a problem in that it is inconvenient because a search operation cannot be performed unless the user wants to know the screen to be viewed in advance or position information near the screen.
Further, when the position from the current screen to the screen to be viewed is distant, the search time becomes long and the usability is poor.

In the third method, when the position from the current screen to the screen to be viewed is distant, the "fast-forward" button or the "fast-reverse" button on the operation unit is kept pressed for a long time, and There is a problem in that it is inconvenient to use because it is necessary to keep watching the monitor.

In view of the above problems, the present invention uses the skip search in which the search direction or the search direction and the skip interval are specified to perform the search so that an image desired to be viewed from the information recording medium mounted in the signal reproducing apparatus is displayed. It is an object of the present invention to provide a signal reproducing device that enables a simple and quick search.

The reproduction address of the video head 6 of the information signal reproducing unit 1 is indicated by point A, the backward search address is indicated by point B, and the forward search address is indicated by point C.

When the reproduction address is used as the reference address by using the skip interval set so as to be widened at each step interval, the reproduction address is deviated in the search direction by the skip interval obtained by the above calculation. The position is calculated as the search position, and the search is performed at this search position. Next, at this search position, a reproduction address is detected, and a position deviated from the reproduction address in the search direction by the skip interval obtained by a new calculation is calculated as a new search position, and a search is performed at this search position. I do. In this way, the video head 6 of the information signal reproducing section 1 is sequentially searched for at the search position.

Here, the predetermined address interval can be set in advance for each specification of the video disc 10 or can be set by the setting unit 3.

It is also possible to change the search direction and the skip interval by operating the search operation member provided in the operation section 3.

The drive control unit 5 compares position information for calculating the position difference between the reproduction address signal transmitted from the reproduction position detection unit 8 of the search position calculation unit 4 and the search position signal transmitted from the position information calculation circuit 9. It has a circuit 11 and a reproduction position control circuit 12 for driving the reproduction drive unit 2 so as to change the position of the information signal reproduced by the information signal reproduction unit 1 in the direction in which the position difference becomes zero.

In this video disc reproducing apparatus, the image signal and the audio signal transmitted from the information signal reproducing section 1 are transmitted to the monitor and the speaker through the main signal processing circuit 13 and searched during the skip search.
