The signal processing circuit 13 equalizes the waveform of the pit information and then outputs it to the system internal bus 15 as an MPEG-2 video stream. At this time, the MPEG-2 video stream is also temporarily stored in the first buffer RAM 16.

Then, the data (MPE output to the system internal bus 15 by the system control microcomputer 17
(G-2 video stream) transfer control is performed. This data is decoded in the video information modulator / demodulator 19 using the second buffer RAM 18 as a video memory. The digital video information signal composed of the decoded 16-bit parallel data is sent to the video information processing unit 22.

The video information processing section 22 converts this digital video information signal into an NTSC signal. The NTSC signal is transmitted to the display panel P via the display generator 23 and the display controller 24. In the display panel P, NTS
The C signal is displayed as a reproduced image and reproduced.

The audio signal is also reproduced in the same manner. That is, similarly to the video data, the MPEG audio stream read from the optical disc D is decoded as an audio signal and is output from a speaker or the like (not shown).

The above-mentioned video signal and audio signal are
It can also be transmitted to an external personal computer via the USB control unit 25.

In the above, the case of reproducing the video information (moving image) recorded in the MPEG-2 format has been described, but the present invention is not limited to this.

For example, a still image using an I picture of the MPEG format or a JPEG image can be displayed on the display panel P via the video information modulator / demodulator 19 as well. The JPEG format encoding (compression) operation is M
The operation is almost the same as the I picture encoding operation of the PEG format. Therefore, in the video information modulation / demodulation unit 19, if a part of the operation of the circuit is switched, the JPEG format decoding operation can be performed.

Next, the operation remote controller (remote control device) for controlling the reproduction of the optical disk reproducing device 1 will be described.

As for the operation state of the optical disc reproducing apparatus 1, the information transmitted from the optical disc reproducing apparatus 1 is received by the interface section 42 and displayed on the operation display section 33.

Information transmitted from the optical disc reproducing apparatus 1 is transmitted via the interface section 42 and the interface microcomputer 41 to the system control microcomputer 39.
Sent to. This information is transmitted to, for example, the system internal bus 3
8 and the USB control unit 43 to output to an external device.

Next, the storage of index information in the optical disc reproducing apparatus 1 will be described.

The index information in this embodiment is composed of title information, guide images, and scene images.

Here, the title information means the optical disc D.
This is information indicating the title of the content recorded in. This title information is, for example, a character string input using the operation keys 20 and 40. Further, the title information may be read from the optical disc D in some cases.

The guide image is a still image of an arbitrary scene in the video information recorded on the optical disc D. This guide image can be selected by using the operation keys 20 and 40 when reproducing the above-mentioned optical disc D.

For example, during reproduction of the optical disc D, the image displayed on the display panel P can be selected by selection using the image determination switches 8.36 as the operation keys 20. Then, the selected image is converted by the video information modulation / demodulation unit 19 into a still image in the JPEG format, for example.

The scene images are still images of a plurality of scenes in the video information recorded on the optical disc D. By using this scene image, for example, it is possible to easily search for a specific scene recorded on one optical disc D.

This scene image may be selected by using the operation keys 20 and 40 as described above during the reproduction of the optical disc D, for example, or as a display control means at every predetermined time. The configuration may be such that selection is made under the control of the system control microcomputer 17. The selected scene image is stored in the non-volatile memory 14. Also, the recording position (address) on the optical disc D corresponding to the scene image, as auxiliary information,
It is stored in the non-volatile memory 14.

Further, together with the still image as the scene image, the elapsed time from the start of reproduction of the optical disc D can be stored in the non-volatile memory 14 as auxiliary information.

The scene images and the recording positions on the optical disc D corresponding to the scene images thus recorded in the non-volatile memory 14 are hereinafter referred to as a scene list.

In the reproduction of the above-mentioned audio data, a part of the reproduced audio data can be attached to the still image file and stored in the non-volatile memory 14. As a result, a still image file with audio data can be stored in the non-volatile memory 14.

Next, the search in the optical disc reproducing apparatus 1 with reference to the index information will be described.

The index information may be stored as described above, but is not limited to this. For example, it may be downloaded via the Internet and stored in the non-volatile memory 14 as a non-volatile storage means.

The optical disk reproducing apparatus 1 of this embodiment uses the operation keys 20 and 40 in order to perform a search using the index information.
An image selection switch 7.35, an image determination switch 8.36, and a cancel switch 9.37 are provided as a part of the above.

The image selection switches 7.35 are switches for selecting a particular image of interest from the images displayed on the display panel P. Image decision switch 8.36
Is a switch for determining the selected image.
The cancel switch 9.37 is a switch for canceling selection of the selected image.

In the optical disc reproducing apparatus 1 of the present embodiment, the pointer is displayed on the display panel P and the operation key 2
It is possible to select an image or the like displayed on the display panel P by linking the movement of the pointer by 0.40 with the display generation unit 23. That is, the pointer displayed on the display panel P by the display generation unit 23 can be moved using the operation keys 20 and 40 to select, determine, or cancel the image displayed on the display panel P.

In the above structure, when input is made by the operation keys 20 and 40, the input data is transmitted to the interface microcomputer 21. Then, the operation is executed via the system control microcomputer 17.

Details of this operation are shown in FIGS.
The description will be made based on the following.

First, when the optical key D, for example, the image determination switch 8.36 of the operation keys 20 and 40 is pressed while the optical disc D is not loaded, a title list display instruction is given.

As shown in FIG. 5, on the display screen P1 of the display panel P, the information of the above-mentioned title list read from the nonvolatile memory 14 is displayed as a plurality of thumbnail images T1.
It is displayed together with the selection pointer X as T12 or the like. This title list is, for example, a collection of title information and guide images respectively selected when reproducing a plurality of optical discs D that have been reproduced so far.

Although the thumbnail images T1 to T12 as guide images in the title list are shown in FIG. 5, the title information is not shown for simplicity.

Since all the title list as the index information is stored in the non-volatile memory 14, the power switches 2 and 32 of the optical disk reproducing apparatus 1 are turned off and the power is turned off. Even when the power is turned on again, the data is read from the non-volatile memory 14 and
You can search efficiently.

In addition, in this way, as the title list,
By displaying the title information, which is character information, and the thumbnail images T1 to T12, which are still images, which are guide images, together, the video information can be searched more visually and accurately.

Next, the selection pointer X is moved by using, for example, the image selection switches 7.35. By this movement, the selection pointer X is moved onto a specific thumbnail image. This can be done while looking at the thumbnail images T1 to T12 as the title list, as described above.

Then, for example, the image decision switch 8.36

Alternatively, the pointer X may be moved by using the selection button 44 to make a selection.

The scroll bar 45 indicates the current display position when the thumbnail image is displayed over a plurality of pages, and is for moving between the plurality of pages. Normally, when the number of thumbnail images recorded as a title list increases, the display screen P1 cannot display all the thumbnail images at once. Therefore, if the current display position is indicated by using the scroll bar 45, the search becomes easy. Further, if the page is moved by using the scroll bar 45, selection can be performed while grasping the current display position, which facilitates the search.

Further, the optical disk reproducing apparatus 1 of this embodiment
