Abstract

PURPOSE:To output the displaying of a composite title picture by recording the composite title picture in the initial setting information of a disk. CONSTITUTION:The title device is provided with a disk 10 to record a composite title picture obtained by reducing a title from a first chapter to an N-th chapter of a program and arranging the reduced picture form the first chapter to the N-th chapter on one picture, a signal reproducing circuit 12 to reproduce a composite title picture signal from a disk 10 at the time of the initial setting and a field memory circuit 13 to store a reproduced composite title picture and output it as a composite title static picture. At the time of the initial setting of a disk reproduction, the composite title picture of a program is outputted as a static picture with one access. Thus, the desired chapter can be retrieved n a short period of time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a composite title screen used as an index during playback by a disk recording/playback device.

BACKGROUND OF THE INVENTION Conventional disc recording and reproducing apparatuses do not record a composite title screen, which is a single screen by reducing the title screen of a program, on a disc, so it was necessary to create a composite title screen during playback. Figure 2 shows chapter 1 of the program.
Title screen from 1 to chapter 4. 2. 3.
4, FIG. 3 shows a composite title screen 9 obtained by reducing the title screens of chapters 1 to 4 of the program and arranging them on one screen, and FIG. 4 shows a block diagram of a conventional disc playback device. show. The pickup 11 reproduces the signal of the first chapter from the disc 10, the signal processing circuit 12 processes it into the title screen 1 of the first chapter, and the screen reduction circuit 15 converts the title screen 1 of the first chapter into a reduced screen of the first chapter. 5. Similarly, the second reduced title screen 6 of the chapter, the reduced title screen 7 of the third chapter, and the reduced title screen 8 of the fourth chapter are taken out and reduced to the screen positions shown in FIG. 3 in the field memory circuit 13. When the screen is inserted and memorized, a composite title screen 9 is configured on the field memory, and the screen output terminal 1
4 is output as a composite title still screen.

Problems to be Solved by the Invention In such a conventional configuration, a composite title screen is not recorded on the disc, so it is necessary to create a composite title screen during playback. You need to play it and reduce the screen size.

Since the pickup 11 accesses the title screen of each chapter, it takes a long time to access it, and it takes several minutes to output the composite title screen.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a disk recording and reproducing apparatus that has a simple configuration and outputs a composite title screen in a short time.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides chapters 1 to N of a program (N is 2.3.
A disc that records a composite title screen obtained by reducing the title screen up to an integer such as 4 and arranging the reduced screens from chapter 1 to chapter N on one screen, and The apparatus is equipped with a signal reproducing circuit for reproducing a composite title screen signal from the disc, and a field memory circuit for storing the reproduced composite title screen in memory and outputting it as a composite title still screen.

Operation According to the above-described configuration, the present invention outputs a composite title screen of a program as a still screen in one access at the time of initial setting of disk playback, so that a desired chapter can be searched for in a short time.

Embodiment FIG. 2 shows a title screen for the first to fourth chapters of the program, FIG. 3 shows a composite title screen in which reduced title screens for the first to fourth chapters are arranged, and FIG. 1 shows one example of the present invention. 1 shows a block diagram of a disc playback device in an embodiment. Title screen for program chapters 1 to 4 1. 2. 3. The title reduction screen for chapters 1 to 4 is a reduction of each of 4 to 1/4 in terms of area. 6. 7.
8, title reduction screen for chapters 1 to 4 5. E3. 7. The composite title screen 9 is a composite title screen 9 in which 8 are arranged and configured on one screen. This composite title screen 9 is recorded in the initial setting information of the disc 10, and when the disc is played back, the composite title screen signal in the initial information signal is taken out from the disc 10 by the pickup 11 and processed by the signal processing circuit 12. The composite title screen 9 is taken into the field memory circuit 13 and outputted from the screen output terminal 14 as a still screen of the composite title screen 9. While looking at this composite title screen 9, the user can understand the program and select the chapter he or she wants to play. In the embodiment described above, the composite title screen 9 is configured into four divided screens, but when there are many chapters and the number of title screens is large, nine divided, 16 divided, 36 divided, etc. are used, and the number of divisions is not limited.

Effects of the Invention As described above, since the present invention records the composite title screen in the initial setting information of the disk, the display of the composite title screen can be finished in a single access operation, and the display can be completed in an extremely short time. You can see the contents of the entire program.
