Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk in a CD-I system, an optical disk reproducing apparatus and an optical disk manufacturing method.

[0002]

2. Description of the Related Art A CD-I system is a system capable of recording image data and audio data and interactively processing with a user. The CD-I system can be used for various services. For example, restaurants have different food menus for breakfast, lunch, and dinner. By recording the image and description of the food menu on the CD-I disc, it is possible to display the screen of the food menu according to each time at breakfast, lunch, and dinner. Then, the user can interactively display each dish and know its contents.

When producing such a CD-I disc, conventionally, it is necessary to develop a dedicated application program for each disc. That is, for example,
In the case of a CD-I disc of a restaurant food menu, a dedicated application program that meets such a demand is conventionally created. This application program runs on a real-time operating system for CD-I. Then, the image data and the audio data such as the image of the food menu and its description are captured, and by this dedicated application program,
These image data and audio data are managed and edited.

[0004]

The CD-I is basically a read-only recording medium. Therefore, conventionally, it is difficult for the user to create a program or edit the program again. For example, in a food menu of a restaurant, a menu limited by the place of sale or a special menu for the day may be prepared. When the cooking menu is changed like this, the user can easily edit the program,
It is desirable to be able to cope with this.

Further, conventionally, when developing a CD-I disc, as described above, it is necessary to develop a dedicated application program for each disc according to the purpose. Therefore, there is a problem that it takes a long time to develop the disc. That is, the CD-I system operates on a dedicated real-time operating system, and conventionally it is necessary to develop an application program on this real-time operating system. Further, in the CD-I, it is indispensable to simulate the developed program with an image on a disc, because it is developed into frames and interleaved for error correction coding. If a dedicated application program is developed for each disk, debugging with such simulation is extremely difficult.

Therefore, an object of the present invention is to provide an optical disk and an optical disk reproducing apparatus in which the user can easily edit the program and the usability is improved.

Another object of the present invention is that it is easy to debug,
An object of the present invention is to provide an optical disc manufacturing method capable of reducing the disc development time.

A. Outline of CD-I System First, the CD-I system will be described. In addition to audio data, data such as image data (natural images, animation, computer graphics data, etc.), text data, computer programs, etc. are recorded together on the CD-I disk.

Various specifications are predetermined for the CD-I disc. That is, the physical properties such as the size, refractive index and track pitch of the disc, the optical properties and the electrical properties are made equal to those of a general music CD (CD-DA). In the CD-I disc, recording and reproduction are performed in units of blocks (sectors) each consisting of 98 frames. The size of this block corresponds to the subcode block of a general CD.

The block structure includes Form 1 and Form 2. In Form 1, as shown in Figure 1A,
In order from the beginning, it has a 12-byte synchronization bit, a 4-byte header, and an 8-byte subheader. In this case, the header indicates an address, etc., and the sub-header indicates the file number, the channel number, and the sub-mode (frame 1 or 2) data type by 2-byte data as shown in FIG. 1C. is there.

Further, following the sub-header, error correction is performed more than the CD-DA disk by using 2048 bytes of user data, 4 bytes of error detection code, 172 bytes of P parity code and 104 bytes of Q parity code. It is becoming more powerful. Therefore, it is suitable for data such as text data and programs that cannot be interpolated during reproduction.

As shown in FIG. 1B, the form 2 has a sync bit, a header, and a subheader, followed by user data, as shown in FIG. 1B. This user data is 2324 bytes, and finally, It has a 4-byte spare area and does not have a code for error correction. Therefore, the form 2 is suitable for data that can be interpolated when reproducing audio data, image data, or the like.

The audio data has the following four modes. That is, in the first mode, the standard in which the audio data is equal to the current CD, that is, the sampling frequency is 44.1 kHz, and the quantization bit number is 16
Written in bits. Therefore, according to this mode, it is possible to obtain the same sound quality as the current CD.

The second, third, and fourth modes are called A, B, and C modes, respectively, and an audio signal is compressed and recorded by ADPCM (adaptive differential PCM). Sampling frequency is 3 in A mode
7.8 kHz, the number of bits is 8 bits, the sampling frequency in B mode is 37.8 kHz, the number of bits is 4 bits, and the sampling frequency in C mode is 18.9 kHz.
z and the number of bits are 4 bits. Therefore, A to C
According to the mode, the sound quality is inferior in order, but the recording and reproducing time can be extended to 2 hours, 4 hours, and 8 hours.

In the case of image data, there are the following three modes. That is, the first mode is used when the image data is natural image data, and in this mode, the luminance signal and the chrominance signal are 8 at 7.6 kHz and 3.8 kHz.
Each bit is digitized and each data is compressed into 4 bits and written. In the second mode, the image is used in the case of animation data, and in this mode, the original data is compressed and recorded using a run length code. Third
In the mode, R, G, and B graphics that use absolute values of red, green, and blue, and C that uses the color correspondence table
An LUT (color lookup table) is used.
The CLUT has three modes of 8-bit, 7-bit, and 4-bit, and a required color can be selected from 16 million colors.

TOC is used for CD-I disc lead-in.
(Table of contents) is provided, and whether the disc is a CD-I disc can be identified from this TOC information.

In CD-I, the CPU used for control
And the operating system are predetermined. A 68000 series CPU is used as the control CPU. A dedicated real-time operating system is used as the operating system.
