Playback of a DA disk (a disk in which a CD-I disk and a CD-DA disk are mixed) can be performed. Here, the data format of the CD-I will be described.

[2] -1. Data Structure CD-I records data in a form based on a CD-ROM. Data recording unit is CD-R
Like OM, it is a block.

The capacity of one block is 2352 bytes. The recording capacity of the entire CD-I disc is 12 cm in diameter.
640 Mbytes in the case of the above-mentioned disk.

There are two types of data structures of CD-I, Form 1 and Form 2, which correspond to Mode 1 and Mode 2 of the CD-ROM, respectively. In the mode 1 of the CD-ROM, an error detection code and an error correction code are added to one block of data so that powerful error correction can be performed. Mode 2 in the CD-ROM has no error detection code and no error correction code, and allows a large amount of user data.

In the CD-I, the form 1 and the form 2 can be specified for each block, and the form 1 and the form 2 can be mixed on one disk.

The difference between the CD-I format and the CD-ROM format is that an 8-byte subheader is provided at the head of user data. In this sub-header, necessary data is double-written and stored in order to perform time-division multiplexing of each block in which sound, image, and data are recorded in block units and to process these in real time. .

Is provided, followed by a header (4 bytes), and a subheader (8 bytes).
Thereafter, user data (2048 bytes) is provided, and an error detection code EDC (4 bytes), P parity for error correction (172 bytes), and Q parity (104 bytes) are added thereto. Form 1 has an improved error correction capability. Form 1 is suitable for handling data such as character data and program data that cannot be subjected to error interpolation.

FIG. 9B shows the structure of Form 2. In Form 2, a sync (12 bytes) is provided at the head, followed by a header (4 bytes), and a sub-header (8 bytes). After this, user data (2324 bytes) is provided, and a reserve area (4 bytes) is further provided. This form 2
Is suitable for handling interpolable data such as audio data and video data.

As shown in FIG. 10, the subheader added to the head of the user data includes a file number (2 bytes), a channel number (2 bytes), a sub mode (2 bytes), and a data type (2 bytes). ).

[2] -2. Writing of Audio There are four modes for writing audio data of CD-I.

One mode has a sampling frequency of 4
4.1 kHz, 16-bit quantization bit, the current C
This is the same recording method as D-DA. This mode is intended for ultra-high fidelity playback.

In another mode, the recording method is A
DPCM (Adaptive Difference PCM) is used. The sampling frequency is 37.8 kHz and the number of quantization bits is 8 bits. In this mode, sound quality comparable to LP records can be reproduced. The playback time is 2 hours for stereo and 4 hours for monaural. This mode is intended for hi-fi playback.

In another mode, the recording method is A
DPCM is used. The sampling frequency is 37.8
kHz, the number of quantization bits is 4 bits. In this mode, sound quality comparable to FM broadcasting can be reproduced. The playback time is 4 hours for stereo and 8 hours for monaural. This mode is intended for long-time Hi-Fi playback.

In another mode, the recording method is as follows.
ADPCM is used. The sampling frequency is 18.
9 kHz, the number of quantization bits is 4 bits. The playback time is 8 hours for stereo and 16 hours for monaural. This mode is intended for speech reproduction.

[2] -3. Video Writing Image data is processed as follows, depending on the type of image data.

In the case of a natural image, the sampling frequency of the luminance signal Y is 7.6 MHz, the sampling frequency of the color difference signals U and V is 3.8 MHz, and sampling is performed at a ratio of 4: 2: 2. Then, each bit is recorded after being compressed to 4 bits, and becomes 8 bits at the time of reproduction.

In the case of graphics, a CLUT (color look-up table) is used. CLUT graphics have 256 colors (8 bits) and 128 colors (7
Bit), 16 modes (4 bits)
The required colors can be selected and used from 16 million colors.

In the case of animation, a run length code is used. In this method, image data is compressed using color information and the length between pixels. Using such a code, full-screen animation can be realized.

[2] -4. Discs For CD-I discs, mechanical parameters such as outer diameter dimension, center hole dimension, and thickness, optical parameters such as refractive index and reflectivity, recording parameters such as disc rotation direction, recording linear velocity, track shape, and track pitch. , The usage environment and the like are all the same as those of a normal compact disk (CD-DA) for music.

Whether the disc is a CD-I disc is determined by the TOC (Table Of C) in the lead-in area of the disc.
ontents). That is, for a CD-I disc or a CD-I / CD-DA disc, the PSEC at (POINT = A0) is set to 10. On the other hand, with other discs, (POIN

Then, the process proceeds from the step 102 to the step 103, and the area 5 of the display 14 is
7, a disk image 58 is displayed.

Next, the routine proceeds to step 104, where the CD-DA
The key input unit 41 determines whether the stop key or the pause key has been pressed. If it is determined that these keys have not been pressed, the process proceeds from step 104 to step 105, where it is determined whether or not a predetermined time has elapsed. If not, the process returns from step 105 to step 104. To step 106. In this step 106, image data to be displayed next is calculated.

Then, from Step 106 to Step 10
Returning to step 2, the ROM 22M is accessed and step 1
The next image data obtained in step 06 is read. Similarly, four image data No. 1 to No. 4
Are sequentially displayed on the display 14 as disk image images 58. As a result, the disk image 58 becomes a rotation animation.

On the other hand, if it is determined in step 104 that the stop key or the pause key has been pressed,
The process proceeds from step 105 to step 107, and the image data 58 of the disk remains displayed with the image data at that time. That is, the disk image 58 is a still image in which rotation is stopped. Then, the process proceeds from step 107 to step 108, where the next image data number is calculated and stored.

Next, from step 108 to step 109
It is determined whether or not the reproduction has been resumed. If not, the flow returns to step 107 to maintain the still image state of the image 58 on the disk. When it is determined in step 109 that the reproduction has been resumed, the process returns to step 102, where the ROM 22M is accessed, and the next image data of the image data at the time of stop indicated by the image data number stored in step 108 is stored. It is read from the ROM 22M. Therefore, the disk image 58
When the stop key or the pause key is pressed, the rotation animation is stopped, and when the reproduction is restarted, the rotation animation is restarted from the stopped image position. Therefore, the rotation animation does not feel uncomfortable.

Next, the CD-I from the CD-I operation screen is displayed.
The animation display of the rotation of the disk image 58 when the disk is started will be described with reference to the flowchart of FIG.

At the time of starting the CD-I, the process proceeds to the step 112 via the step 111 to start the rotation of the physical disk, that is, the operation of selecting the [CD-I Start] icon button on the CD-I operation screen of FIG. 14A. Is confirmed, and the routine proceeds to step 113. This step 1
At 13, the ROM 22M storing the four image data No. 1 to No. 4 is accessed, and one of them is read. Then, the process proceeds from step 113 to step 114, and the display 14 is displayed based on the read image data.
A disk image 58 is displayed in the area 57 of FIG.

Next, from step 114 to step 115
Then, it is determined whether or not a predetermined time has elapsed. When the predetermined time has elapsed, the process proceeds from step 115 to step 116. In this step 116, it is determined whether or not the time required for the CD-I disk to rotate stably has elapsed. If it is determined that the CD-I disk has not reached stable rotation, the process proceeds to step 117, where the image to be displayed next is displayed. A calculation is made of which data number.

Then, steps 117 to 11
3, the ROM 22M is accessed, and step 1 is executed.
The next image data calculated by 17 is read. In the same manner, four pieces of image data
No. 1 to No. 4 are sequentially displayed on the display 14 as disc images 57. As a result, the disk image 58 is in a state of animation of rotation.

Then, in step 116, the CD-
If it is determined that the time required for the I disk to rotate stably has elapsed, the process proceeds to step 118, where the actual CD-
The I application is activated. At this time, the display screen of the display 14 changes from the CD-I operation screen to the application screen.

As described above, the waiting time of several seconds until the rotation of the disk is stabilized until the actual application starts when the CD-I disk is booted is determined by the image 58 of the disk being rotated on the CD-I operation screen. An animation is displayed, and the user is notified that it is running.

In the above example, the animation of the disk rotation is realized by switching a plurality of images at a fixed period. However, as the image image of the disk, only one image similar to the above example is prepared. By changing the color or brightness of each sector-shaped area Ar at a constant cycle, an animation of the rotation of the disk can be performed.

That is, in this case, for example, FIG.
As shown in the figure, the circle is divided into 16 fan-shaped regions Ar # 1 to # 16.
Is prepared in the ROM 22M. Also,
In the ROM 22M, the 16 fan-shaped regions Ar # 1 to Ar # 1
In this example, r # 16 is a color lookup table for designating each color, for example, as shown in FIG.
The tables CLUT1 to CLUT4 are also stored. In the case of this example, the four tables CLUT1 to CLUT4 are such that, as is clear from FIG. 5, the area positions of the same color sequentially change in the clockwise direction.

These images VI and four tables CLUT
FIG. 6 shows an example of a flowchart for realizing an animation of the rotation of the disk image 58 using 1 to CLUT4. This example is an example in which the present invention is applied when a CD-I disk is started.

That is, when the CD-I is started, step 1
Then, the process proceeds to step 122 via 21, the rotation of the physical disk is started, that is, the operation of selecting the [CD-I Start] icon button on the CD-I operation screen in FIG. In this step 123, the ROM 22M is accessed and the image V
The data of I and one of the data of the four tables CLUT1 to CLUT4 are selectively read. Then, the process proceeds from step 123 to step 124, where the color look-up table is rewritten with the data of the read table, and the color of each area of the image VI is specified by the color look-up table. Then, the process proceeds from the step 124 to the step 125, and the image image 58 of the disk in the area 57 of the display 14 is displayed by the color display data of the image VI.

Next, from step 125 to step 126
Then, it is determined whether or not a predetermined time has elapsed. When the predetermined time has elapsed, the process proceeds from step 126 to step 127. In this step 127, it is determined whether or not the time required for the CD-I disk to rotate stably has elapsed. If it is determined that the CD-I disk has not reached stable rotation, the process proceeds to step 128, where the next image to be displayed is displayed. Table
Any one of the tables CLUT1 to CLUT4 is calculated.

Then, from step 128 to step 12
3, the ROM 22M is accessed, and step 1 is executed.
The next image data obtained by calculation at 28 is read. Similarly, four tables CL are set at regular intervals.
The images VI in which the colors of each of the 16 regions Ar are determined by UT1 to CLUT4 are sequentially displayed on the display 14 as a disk image 58. As a result, the disk image 58 becomes a rotation animation.

Then, in step 127, the CD-
If it is determined that the time required for the I disk to rotate stably has elapsed, the process proceeds to step 129, where the actual CD-
The I application is activated, and the display screen of the display 14 changes from the CD-I operation screen to the application screen.

Instead of preparing four tables, the rotation animation can be similarly performed by changing the address of each color of one color table at regular intervals. However, when four tables are used, it is not necessary to rewrite the addresses of the tables, so that the speed can be increased and the degree of freedom to select various forms of images as the disk rotation image is large.

[6] Description of Operation of Embodiment FIGS. 15 and 16 are flowcharts showing an example of the operation of this embodiment. Hereinafter, this operation will be described. This shows the operation when the display 14 is turned on.

That is, when the power switch 5 is turned on and the power is turned on, the flow enters the flowchart of this example from step 201. Then, the process proceeds to step 202, where it is determined whether or not the system file (CSD file) in the nonvolatile RAM 39 (which is made nonvolatile by the backup battery) is normal. This determination is made by opening the CSD file in the nonvolatile RAM 39. If the CSD file can be opened, it is determined that the CSD file is normal, and the process proceeds to step 204. If the CSD file cannot be opened, the CS
It is determined that the D file has not been copied to the nonvolatile RAM, and the process proceeds to step 203.

The reason why the CSD file is not copied normally is that many or large files exist in the nonvolatile RAM, and the capacity for copying the CSD file cannot be secured. Therefore, in step 203, a screen for erasing the file in the nonvolatile RAM 39 is displayed to prompt the user to erase the file. The user erases the file,
When the capacity for copying the CSD file has been secured, it is reset internally. After the reset, the status is the same as immediately after the power is turned on.
Go to 02.

In step 204, it is determined whether or not there is a button input for shifting to the setting mode described above. That is, it is determined whether or not the trigger buttons 12a and 12b have been pressed simultaneously. If it is determined that the trigger buttons 12a and 12b have been pressed simultaneously, the process proceeds to step 205 of the initial setting mode; otherwise, the process proceeds to step 206.

In step 205, the above-described initial setting mode is executed, and the above-described setting items such as an initial screen, a clock display, a calendar, and a world clock are set. Sex R
Stored in AM.

When the initial setting mode of step 205 is completed, the process proceeds to step 210, where the display 14
Area 57 of the built-in function display screen
Displays a blank menu screen, and then displays step 21
Proceed to 1.

In step 204, the trigger button 1
When it is determined that the operations of 2a and 12b have not been performed, the process proceeds to step 206, where a menu screen is displayed as a display screen of the display 14, and thereafter, step 2 is performed.
Proceed to 07. In this step 207, the user makes various settings in the initial setting mode, and it is determined whether or not the contents of the data stored in the built-in RAM of the system controller 22 are correct. This determination is based on the internal RAM
This is done using the consistency of the checksum with the fixed value written to. If the contents of the RAM are correct, the process proceeds to step 211; otherwise, the process proceeds to step 208.

In step 208, the built-in RAM stores
A default value including the date and time setting value is written, and a message is displayed on the display 14 asking whether to make various settings in the initial setting mode. Then, when the user inputs to perform the initial setting, the process proceeds to step 209 to enter the initial setting mode as in step 205,
Each setting is performed as described above, and the set data is written to the built-in nonvolatile RAM. If the user does not make a setting, the process proceeds to step 210, and a menu screen is displayed on the display 14.

Then, in step 211, it is determined whether or not the inner lid 7 is open. If the inner cover 7 is open, it is determined that the disc is not loaded, and the process proceeds to step 217, and the display mode of the screen of the built-in function display system (referred to as a clock system screen mode) is set. Is displayed in the area 57.

If it is determined in step 211 that the inner cover 7 is closed, the flow advances to step 212 to determine whether the disk is mounted on the disk mounting unit. When it is determined that the disk is not loaded, the process proceeds to step 217, and the timepiece-based screen mode is set. When it is determined that the disk is loaded, the process proceeds to step 213. In step 213, the innermost TOC of the disk is accessed, and the type of the disk is determined from the data of the TOC.

In this case, the disc is CD-I or C
What is treated as DI, CD-DA, or CD-DA
CD-I / CD-DA or CD-
I / CD-DA is classified into four types. Then, in this step 213, the CD-I,
If it is determined that the disc is a CD-DA, a CD-ICD-DA, or a disc to be treated as such, step 2
The flow proceeds to step 214, and if it is determined that the disk is another disk, the flow proceeds to step 214.

At step 214, a message is displayed on the display 14 informing the user that the disc cannot be handled by the CD-I player of this embodiment. Thereafter, the process proceeds to step 215.

In step 215, while the message displayed in step 214 is being displayed, the system waits until the inner lid 7 is opened. When the inner lid 7 is opened, the process proceeds to step 217 of the clock-based screen mode, and The display changes to the initially set built-in function display screen.

In the timepiece screen mode of step 217, four built-in functions can be selected and switched to the built-in function display screen by selecting and specifying the icons 51 to 54. The screen display does not change even if the inner lid 7 is opened while the clock system screen is displayed. However, if it is determined in step 219 that the inner lid 7 is closed, there is a possibility that a disk has been inserted. Therefore, the process returns to step 212 to check whether or not a disc has been loaded.

At step 213, as a result of discriminating the type based on the TOC data of the disc, the CD-I, CD-DA,
After it is determined that the disc is a CD-I / CD-DA or a disc to be handled as such, in step 216 executed, the above-described operation screen (referred to as a play-based screen mode) corresponding to the discriminated disc is performed. Is display 1
4 is displayed.

On the CD-I operation screen in the play screen mode, loading and starting of a CD-I disc can be performed as described above. CD-DA
On the operation screen, the CD-DA key input unit 41 of the main unit 2 operates the CD-DA in the same manner as a normal CD player.
A DA disc can be reproduced. In addition, CD
-In the I / CD-DA operation screen, the icons 55 and 56 are displayed for the CD-I operation screen and the CD-DA operation screen.
Can be switched by selecting.

As described above, during the waiting time at the start of the CD-I disc on the CD-I operation screen and during the playback of the CD-DA disc, the disc image 58 is used as a rotation animation. ,
It is displayed on the display 14. Therefore, the user can visually grasp the state where the disk is rotating, and can easily confirm the rotation of the disk even in an apparatus without a disk window.

In the play system screen mode, by selecting any of the icons 51 to 54, it is possible to switch to the selected built-in function display screen in the clock system screen mode. Then, in the clock mode in which the built-in function display screen is displayed after the switching, the CD-
Since the DA icon 55 and / or the CD-I icon 56 are displayed on the screen of the display 14, by selecting these icons 55 and 56, it is possible to switch to the selected operation screen of the play system screen. it can.

Then, when the middle cover 7 is opened while the play screen of step 216 is being displayed, this is determined in step 218, and the flow advances to step 217. At this time, the built-in function screen displayed on the display 14 is the last built-in function screen displayed while the power is on. After the power is turned on, a direct play screen is displayed. If there is no built-in display screen displayed last, the initial screen set in the initial setting mode is displayed.

It is needless to say that the present invention can be applied not only to a CD-I player but also to a disk player for reproducing other optical disks and magneto-optical disks.

[0111]

As described above, according to the present invention, when the disc mounted on the player is rotating, the animation of the rotating image is displayed on the display. However, the user can easily visually confirm the rotation of the disk.

Then, when the CD-I disk starts up, it is possible to display on the display that the disk is rotating during the waiting time for activation, so that the user can easily recognize that the disk is being activated. Can be announced.

Further, according to the present invention, a plurality of images are prepared in the memory, and a rotation animation is performed by switching the plurality of images, so that a simple and high-speed rotated image can be displayed. it can.
