Abstract

PROBLEM TO BE SOLVED: To simplify the reproduction or erasure of a program by selecting one program or over recorded on a magnetic tape while referencing a representative image and pointing out the image directly. SOLUTION: When a magnetic tape 100 is loaded at first, a tape ID detector 112 detects a tape ID to check whether or not program information is registered. When not registered, a start position 102 of a program 101, an image 103, and an end position 300 are respectively detected by a program start position detector 104, an image detector 105, and a program end position detector 301 and stored in a program information storage device 107. When a reproduction command signal 110 is given from an operation section 109, a program reproduction device 111 conducts high speed feeding up to an object program 101 and reproduces an image up to the end position 300 from the start position 102. Thus, the user of a VTR easily grasps the content of a program by observing a multi-image pattern to easily reproduce or erase a desired program.

BEST MODE FOR CARRYING OUT THE INVENTION A video reproducing apparatus according to a first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing the overall configuration of the video reproducing apparatus of the first embodiment. The magnetic tape 100 is a recording medium used in a video reproducing device. One or more programs are recorded on the magnetic tape 100,
One of them is the program 101. This program 101 is recorded from a start position 102 to a certain end position.
The image 103 is an image of one or more frames selected from the program 101, and is a representative screen showing the content of the program.

The program start position detector 104 detects the start position 102 of the program 101 and assigns the program identification number 10 to the program.
6 is a circuit for adding 6. The image detector 105 is the program 10
This is a circuit for detecting the image 103 from 1 as a representative screen. The program information storage unit 107 stores the start position 10 of the program 101.
2 and the image 103 are stored in the circuit and include a memory. The image display 108 is a circuit for displaying the image 103 on a small screen, and the reproduction command signal 11 of the operation unit 109.
Controlled by 0. The program reproducer 111 outputs a drive signal to the drive means of the magnetic tape 100 and reproduces the image 103 stored in the program information storage 107,
This circuit outputs the image signal of the entire program 101 by normal reproduction of the magnetic tape.

The tape ID detector 112 detects the tape ID 113 recorded on the tape cassette or the magnetic tape held in the tape cassette, and the program information storage unit 107.
It is a circuit for checking whether or not the same tape ID 113 is already stored, and newly registering the same tape ID 113 if it is not stored.

The operation of the video reproducing apparatus of the first embodiment thus constructed will be described. When the magnetic tape 100 is mounted on the video reproducing apparatus, the tape ID 113 unique to the magnetic tape is detected by the tape ID detector 112. The tape ID detector 112 is the program information storage unit 107.
If the tape ID 113 is not registered in the above, it is determined that the magnetic tape 100 has never been used in the video reproducing apparatus. In this case, in order to newly register the program information recorded on the magnetic tape 100, the tape must be scanned from the beginning end to the end.

When the reproduction of the magnetic tape 100 is started at a normal speed or a high speed, the start position 102 of the program 101 and its image 103 recorded on the magnetic tape 100 are detected as a program start position detector 104 and an image detector 105, respectively. Detected by. When the program start position detector 104 detects a plurality of programs, each program has a different program identification number 1
Give 06. Detected start position 102, image 10
3, and the added program identification number 106 is stored in the program information storage 107.

When the reproduction of all the programs recorded on the magnetic tape 100 is completed or the reproduction of the programs up to the intended portion is completed, the respective images 103 are transferred from the program information storage unit 107 to the image display unit 108. Is displayed on a small screen. The program identification number 106 is the image display 108.
Is stored in the memory associated with. Such an operation is performed for all the programs recorded on the magnetic tape 100. The above operation may be performed only for one or more arbitrarily selected programs.

The user of the video reproducing apparatus looks at the image 103 of the small screen displayed on the image display 108 as shown in FIG. 2 and designates the small screen of the desired program through the operation unit 109. Then, the reproduction command signal 110 is sent from the operation unit 109 to the image display device 108. As the operation unit 109, a pointing device such as a mouse or a light pen,
Alternatively, using a touching panel or the like that directly touches the screen with a finger simplifies the operation. However, other input means may be used.

When the reproduction command signal 110 is sent to the image display device 108, the program identification number 106 of the program is sent to the program information storage device 107 from the memory associated with the image display device 108. Then, the start position 102 of the program is called. The called start position 102 is the program player 1.
11 is sent to the magnetic tape 10
0 is rewound or fast-forwarded to the start position 102, and the reproduction of the program 101 is started.

FIG. 2 is a diagram showing an example of the display contents of the image display device 108. A mouse is used as the operation unit, and a program is selected by the mouse cursor shown by the arrow. In this example, the image display unit 108 displays the image 103 stored in the video information storage unit 107 on a small screen for each program. The user of the video reproduction device selects a program by looking at the image 103 on the small screen and clicks the mouse on the small screen to send the reproduction command signal 110 to reproduce the specified program.

Incidentally, when another magnetic tape is attached to the video reproducing apparatus, the tape ID detector 112 is known to the known tape I.
When D113 is detected, the program information of the magnetic tape may be stored in the program information storage 107.
In such a case, the user of the video reproducing apparatus can immediately search the program content and select the desired program through the operation unit 109. Whether or not the program information is stored depends on the memory capacity used in the program information storage unit 107. Generally, it is assumed that the program of the magnetic tape loaded later is stored with priority over the program of the magnetic tape loaded earlier. Therefore, the amount of program information stored depends on the memory capacity.
