Further, the video CD control unit 8 is
In step S13, the system control unit 11
A CD reproduction start command is transmitted to the CD mechanical control unit 3 via the. After that, in step S14, the video CD control unit 8 checks the presence / absence of the user's key input, and if there is the key input, the key input processing corresponding to the key input is performed.
Then, when the MPEG circuit unit 4 interrupts the video CD control unit 8, the video CD control unit 8 analyzes the interrupt processing data transmitted together with the interrupt in step S15, and the analysis result is obtained. Based on this, a predetermined command is transmitted to the MPEG circuit section 4 and the CD mechanical controller section 3.

Next, the processing procedure of the playback control will be described with reference to FIGS. First, in step S21 of FIG. 5, the play item described in the predetermined list is reproduced, and then in step S22, the user operates the remote controller 12 to determine whether or not there is a key input. Then, step S2
In 3, the playback control process is performed according to the determination result. That is, the reproduction control is transferred to the play list or the selection list according to the determination result of step S22.

The flowchart of FIG. 6 shows a processing procedure when a play list is executed as a predetermined list. In the figure, steps S31 to S34
And the processing of S39 is the same as the processing of step S22 of FIG.
The processes of steps S35 to S38 and S40 correspond to the process of step S23 of FIG. 5, respectively. When the play list is executed, the play item specified by the play item number (Play Item Number) described in the play list is reproduced. After that, the video CD control unit 8 performs steps S31 to S3.
In 3, it is determined whether or not the pre-ski key, the next key, or the return key has been operated.
When determining that any key has been operated, the video CD control unit 8 performs a process corresponding to a key input corresponding to the operated key. That is, Priviasky,
When the next key or the return key is operated,
A list (Previous List, Next List, Return List) specified by the previous list offset (Previous List Offset), next list offset (Next List Offset), or return list offset (Return List Offset) described in the playlist. Are respectively executed in steps S35 to S37.

Further, in step S34, the automatic pause wait time (Auto Pause Wai
t Time) is set, and if the auto pause wait time is set, a waiting time is set for a specified time in step S38. Further, if there is no key input, it is determined in step S39, and in step S40, the list specified by the next list offset (Next Lis
t) is executed in step S40.

Specifically, for example, PSD. When the first list of the VCD is a play list and the play list is executed, the video CD control unit 8 performs the following process. That is, first, the binary data (word) of the area in which the list ID number of the play list is stored is read from the SRAM 9, and the values of bit0 to bit14 of the binary data are the list I.
Checked as D number. As a result, when it is confirmed that the list ID number is 0001, the play item number (Play I
tem #n Number), the video CD 1 is reproduced.

That is, the play item number (binary 2
When byte) is 0 or 1, no processing is performed. When the play item number is any value from 2 to 99, the reproduction from the track number is performed.

Specifically, first, INFO. S in VCD
size Map of TRACKMotion Pi
cture information (byte position 31-
NTSC / PAL of each track specified in 43)
Based on the information, the reproduction mode of the MPEG circuit unit 4 is Set.
It is set by the Stream command. Next, the start address (address) and the end address of the reproduction target track are calculated from the TOC information, and a moving image reproduction macro command (Play (start address, end address) command) is transmitted to the MPEG circuit unit 4. Furthermore, for the CD mechanical control unit 3,
A Play (start address) command is transmitted.

When the CD mechanical control section 3 receives the start address together with the Play command from the video CD control section 8, the video C control section 3 receives the video C corresponding to the start address.
CD based on subcode Q of TOC information in D1
Servo control of the drive unit 2 is performed, thereby causing the CD drive unit 2 to reproduce the data from the start address transmitted together with the Play command. The playback data is
MPE from the CD drive unit 2 via the CD mechanical control unit 3
It is supplied to the G circuit unit 4 and is output from the speaker 16 or the monitor 17 as described above.

After that, when the address included in the data supplied from the CD drive section 2 to the MPEG circuit section 4 via the mechanical control section 3 exceeds the above-mentioned end address, the MPEG circuit section 4 causes the video CD control section 8 to operate. In response, an end address interrupt is generated. Upon receiving the end address interrupt from the MPEG circuit unit 4, the video CD control unit 8 sends a stop command to the CD mechanical control unit 3. As a result, the reproduction of the video CD 1 is stopped.

If the play item number is any value from 100 to 599, 99 is subtracted from the number. Then, the entry point whose entry number is the subtracted value is ENTRY. It is recognized by referring to the VCD, and from that entry point to the end of the track in which the entry point is set is played. Specifically, INFO. Si in VCD
ze Map ofTRACK Motion Pic

Based on the PAL information, the reproduction mode of the MPEG circuit unit 4 is set by the Set Stream command. further,
ENTRY. The start address and the end address of the reproduction target track are calculated from the VCD and the TOC information, and the moving picture reproduction macro command (Play (start address, end address) command) is transmitted to the MPEG circuit unit 4 and the CD is transmitted.
A Play (start address) command is transmitted to the mechanical control unit 3.

As a result, reproduction is started from the start address (start address) of the video CD 1. After that, when the reproduction up to the end address is performed, the end address interrupt is generated in the MPEG circuit unit 4 as described above, and thus the reproduction of the video CD 1 is stopped.

If the play item number is any value from 1000 to 2979, the segment play item corresponding to the value obtained by subtracting 999 from that value is reproduced. When playing a segment play item, INF
O. By referring to the VCD, the start address and the end address thereof are calculated, and the INFO. VC
Segment play item cont in D
The type of MPEG data as a segment play item is determined by referring to the target content data (1 byte) in the ents table.
Then, the decoding type setting according to the value is MP
This is performed by transmitting a Set Stream command to the EG circuit unit 4, and the segment play item (MPEG data) is reproduced.

The play list describes a play item wait time (1 byte) that defines the waiting time after each play item is reproduced. If the value is 0, the waiting time is set. However, if 1 to 60, the waiting time of 1 to 60 seconds is n (however, n is 61 or more and less than FFH).
If the waiting time of 60) × 10 + 60 seconds is FFH, an infinite waiting time is set. This waiting process is canceled by the user's key input.

The waiting time is also set in the sector where the trigger bit is set. That is, when the trigger bit is set in the sector, the MPEG circuit unit 4
Auto Pause (Auto Pause) (trigger) Interrupt (A
(P / EOR / EOF interrupt) is generated, whereby a waiting time is set for the time defined by the above-described auto pause wait time. Note that this processing is also canceled by the user's key input.

When the pre-bias key, the next key, or the return key is operated during the execution of the play list as described above, another list is displayed in correspondence with the operated key as described above. The reproduction control shifts.

If none of the pre-ski key, the next key, or the return key is operated during the execution of the play list, that is, all the reproduction processes corresponding to the play item numbers described in the play list are executed. In this case, as described above, the reproduction control shifts to the next list.

The flowchart of FIG. 7 shows a processing procedure when the selection list is executed as the predetermined list in step S21 of FIG. In the figure, the processes of steps S41 to S45 and S51 are the same as those of step S22 of FIG.
The processing of steps S50 and S52 is performed in step S23 of FIG.
Processing of each corresponds to. When the selection list is executed, the video CD control unit 8 operates the pre-key key, the next key, the default key (playback key), the return key, or the ten-key (numerical key) and then the return key in steps S41 to S45. It is determined whether or not each has been performed. Then, when any key is operated, a list corresponding to the key input corresponding to the operated key is displayed in steps S46 to S50.
Run on each.

Further, according to the selection list, the loop count (Loop Count & Jump) described therein is displayed.
If the play item is repeatedly played only for bits 0 to 6) of Timing, but there is no key input by the time corresponding to the wait time (Wait Time for Time-out) after the end of the playing, That is, in the case of time-out, it is determined in step S51, and step S51
In step 52, the list specified by the Time-out List Offset described in the selection list is executed.

Specifically, for example, PSD. When the first list of VCD is a selection list and the selection list is executed (however, it is not multi-selection), binary data (word) from the area where the list ID number of the selection list is stored
Is read out, and the values of bit0 to bit14 are checked as the list ID number. When the list ID number is 0001, the default list offset (Defa
If ult List Offset) is not FFFDh or FFFEh (not multi-selection), processing is performed corresponding to the play item number (Play Item Number).

That is, as in the case of the play list described above, if the play item number is 0 or 1, no particular process is performed. Also, if the play item number is any value from 2 to 99, the reproduction process from that track number is performed, and if it is any value from 100 to 599, the entry corresponding to the value obtained by subtracting 99 from that value. Reproduction processing from the point is performed. further,
If the play item number is any value from 1000 to 2929, the segment play item is reproduced with a value obtained by subtracting 999 from the value.

When the return key is operated subsequent to the previa key, the next key, the default key, the return key, or the numeric key during the execution of the selection list as described above, it corresponds to the operated key. Then, the reproduction control is transferred to another list. That is, when the PREVIOUS key, the next key, the default key, or the return key is operated, the preceding list offset, the next list offset, and the default list offset (Default Li
st Offset) or the list specified by the return list offset is executed. In addition, when the return key is operated after the number (however, 1 to 99) is input by the number keys, the selection number offset (Selection Base) described in the selection list is selected.
of Selection Number Offset) is executed and the list specified by the selection number offset corresponding to the input number is executed.

When the next list offset, the default list offset, or the selection number offset is FFFFh, the operation of the next key, the default key, or the numeric key is ignored.

On the other hand, when a time-out occurs, as described above, the reproduction control shifts to the list specified by the time-out list offset described in the selection list. However, if the timeout list offset is FFFFh and a timeout occurs, the list specified by any selection number list offset described in the selection list is executed. That is, in this case, the selection number list offset described in the selection list is randomly selected, and the list specified thereby is executed.

When the bit 0 of Loop Count & Jump Timing described in the selection list is 0, the reproduction of the play item is repeated indefinitely. Also, if the bit 7 is 0, when there is a key input, the playback control is immediately transferred to another list, but if the bit 7 is 1, the playback of the currently played play item ends. Then, the reproduction control is transferred to another list.

Next, FIG. 8 shows a configuration example of an MPEG decoding IC incorporated in the MPEG circuit section 4. MP
The EG decoding IC is an MPE that performs MPEG decoding.
G processing unit 30, MPEG processing unit 30, and display control unit 5
It is composed of a control unit 40 for controlling 0, and a display control unit 50 for controlling windows such as opening and closing of windows and displaying video data in the opened windows.

The MPEG processing section 30 includes a buffer 31, C
It is composed of a D-ROM decoding section 32, an AV separation section 33, and a decoding section 34. The buffer 31 is C
The bit stream (serial data) from the D mechanical control unit 3 is temporarily stored. CD-ROM
The decoding unit 32 reads the data stored in the buffer 31, forms CD-ROM-XA format frame data from the data, and outputs the frame data to the AV separation unit 33. In addition, the CD-ROM decoding unit 32 includes a ROM header of the frame data (ROM-he
ader) (a header in which a frame address, a frame type, etc. are described) is extracted and output to the control unit 40.

The AV separation unit 33 separates the frame data supplied from the CD-ROM decoding unit 32 into video data and audio data, and outputs them to the decoding unit 34. The decoding unit 34 includes a video decoder 34V and an audio decoder 34A, and the video or audio data from the AV separation unit 33 is MPEG-decoded in each of them.

The control section 40 includes a CPU (RISC microcomputer (microcomputer)) 41, a CD-ROM-XA.
Header information register 42, DRAM 43, command buffer 44, status register 45, and I / F 46
And each block is connected to each other via a bus (in this embodiment, an 8-bit bus, for example). The CPU 41 executes commands stored in the command buffer 44 to control the MPEG processing unit 30 and the display control unit 50 and other processes. Further, the CPU 41 is also configured to supply the status register 45 with information (hereinafter, appropriately referred to as processing result information) regarding whether or not the processing can be normally performed after performing the predetermined processing. . Further, the CPU 41 reads out the ROM header extracted by the CD-ROM decoding unit 32 for each frame,
-ROM-XA header information register 42 is also provided.

CD-ROM-XA header information register 4
2 stores the ROM header supplied from the CPU 41. The DRAM 43 stores data necessary for the operation of the MPEG processing unit 30. The command buffer 44 temporarily stores the command supplied from the video CD control unit 8 via the I / F 46. Status register 4
5 stores the processing result information supplied from the CPU 41. The I / F 46 controls the communication with the video CD control unit 8. The I / F 46 and the video CD control unit 8
Are connected via, for example, an 8-bit bus and an interrupt signal line for interrupting the video CD control unit 8.

In the MPEG decoding IC configured as described above, when the bit stream from the CD mechanical controller 3 is input to and stored in the buffer 31, the CD-RO
In the M decoding unit 32, the data is read from the buffer 31 as appropriate, and the frame data of the CD-ROM-XA format is formed. Further, the CD-ROM decoding unit 32 extracts the ROM header from the frame data and supplies it to the CD-ROM-XA header information register of the control unit 40 for storage.

Here, there are frame data that includes MPEG data and frame data that includes PBC. As described above, the video CD control unit 8 determines an address at which the reproduction is started and an address at which the reproduction is stopped when the video CD is reproduced. This reproduction command is transmitted to the IC for use in the case of reproducing the frame data including the MPEG data and the case of reproducing the frame data including the PBC (video CD control data). So, different things are being used.

Hereinafter, MPEG data or PBC will be used as appropriate.
When the reproduction command for reproducing the frame data including the MPEG data is a MPEG data reproduction command or the PBC reproduction command, the video CD control unit 8 controls the frame data including the MPEG data or the PBC. I / F4 when playing
6, the MPEG data reproduction command or the PBC reproduction command is set in the command buffer 44. The CPU 41 reads the command set in the command buffer 44, and in response to the command,
It controls the MPEG processing unit 30. Information regarding whether or not this control is normally performed, that is, processing result information is set in the status register 45.

When the command set in the command buffer 44 is a PBC playback command, CD-RO
The M decoding unit 32 supplies the frame data (PBC) to the DRAM 43 of the control unit 40 to store it. In addition,
The PBC stored in the DRAM 43 is transferred to the DRAM 5 at a predetermined timing.

On the other hand, when the command set in the command buffer 44 is the MPEG data reproducing command, the CD-ROM decoding section 32 outputs the frame data (MPEG data) to the AV separating section 33.

In the AV separation unit 33, the frame data supplied from the CD-ROM decoding unit 32 is separated into video or audio data, which are output to the video decoder 34V or audio decoder 34A of the decoding unit 34, respectively. . In the video decoder 34V or the audio decoder 34A, the video or audio data from the AV separation unit 33 is MPEG-decoded and output. In the decoding process of the decoding unit 34, the DRAM 43 is used when an area for storing data is needed.

The video data MPEG-decoded by the video decoder 34V is supplied to the display controller 50.
The display control unit 50 has a built-in VRAM (Video RAM),
Under the control of the control unit 40 (CPU 41), the display control of the MPEG-decoded video data is performed by writing the data in the VRAM. As a result, the monitor 17
A window is opened and the video data is displayed in that window. Also, the opened window is closed or a cursor having a predetermined shape is displayed.

The cursor can be moved by operating the remote controller 12, and a predetermined position on the monitor 17 can be selected (instructed). That is, when the cursor key of the remote controller 12 is operated, an operation signal (hereinafter, appropriately referred to as a cursor operation signal) corresponding to the operation is sent via the system control unit 11 and the video CD control unit 8 to the MPEG circuit unit 4 Is supplied to. In the MPEG circuit unit 4, the cursor operation signal is received by the CPU 41, and the display control unit 50 is controlled so as to move the cursor in response to the cursor operation signal. Alternatively, the display control unit 50 supplies position information such as the coordinates of the monitor 17 on which the cursor is positioned to the video CD control unit 8 via the control unit 40, whereby the video CD control unit 8 receives the position information. For example, of the options forming the menu screen displayed on the monitor 17, the one selected (instructed) by the user is recognized.

When a window is opened on the monitor 17 and a menu screen having options is displayed in the window, the remote controller 12 is operated to select one of the options with the cursor. Then, the MPEG data (video data) corresponding to the option is reproduced according to the PBC (list). Then, if the MPEG data is in a lower layer than the MPEG data displayed in the currently opened window, a new window is opened and that window becomes the active window. Furthermore, in the active window,
MPEG played by selecting an option
Data, that is, lower layer MPEG data is displayed.

In the same manner, the MP data in the lower layer than the MPEG data displayed in the active window is similarly processed.
When the reproduction of the EG data is instructed, a new window is opened, and the MPEG data for which the reproduction is instructed is displayed in that window.

Therefore, the user can easily recognize the entire hierarchical structure of the MPEG data recorded on the video CD 1.

Further, in the upper left part of the window, for example, a display for closing the window (hereinafter,
There is a close box as necessary), and when the close box is instructed to be closed by operating (instructing) the close box, the display control unit 50 closes the window. Then, the display control unit 50 activates the window in which the MPEG data in the upper layer of the MPEG data displayed in the closed window is displayed.

Therefore, the MPE recorded on the video CD 1
When the number of layers of G data is large, when entering a deep layer, it is possible to easily return to the upper layer.
Further, in this case, the list pointer (the pointer at which the start address of the list to be executed is set) is not changed by operating the pre-ski key or the return key of the remote controller 12 as in the conventional case, but the close box By operating the, the list pointer is changed, and by doing so, it is possible to return to the upper hierarchy, so that it is possible to provide the user with an easy-to-understand operating environment. That is, the user interface can be improved.

Further, when a plurality of windows are opened and the cursor is moved to any one of the windows and the window is designated, the display control unit 50 activates the window until now. Activate instead of the previously set window.

In order to reproduce the MPEG data desired by the user, normally, the list ID (scene number) of the list for reproducing the MPEG data is stored, and the address (list to be executed) corresponding to the list ID is stored. It is necessary to transfer the reproduction control to the list corresponding to the list ID by setting (the first address of the list) to the list pointer, but in the above case, the user does not store the list ID, It is possible to reproduce desired MPEG data.

Further, the window displayed by the display control unit 50 can be changed in size, display position, etc. by operating the cursor with the remote controller 12, whereby the window can be changed. It is designed so that it can be displayed so that it does not overlap with other windows. Therefore, it is possible to make the window easy to see.

On the other hand, the audio data decoded by the audio decoder 34A is the D / A as described above.
It is supplied to the speaker 16 via the converter 7 and output.

By the way, in the video CD reproducing apparatus of FIG. 1, when the video data is reproduced from the video CD 1, the system controller 11 causes the video C to be reproduced.
As described above, the request command for the address-related information is periodically transmitted to the D control unit 8.

Upon receiving the address related information request command, the video CD control unit 8 reads out the address described in the ROM header from the CD-ROM-XA header information register 42 via the I / F 46, and reads out the address. , PBC stored in the SRAM 9 are compared to calculate a scene number and an index number.

That is, in the video CD control section 8,
From the address read from the CD-ROM-XA header information register 42, the value of the currently executed list, that is, the scene number is obtained. Further, in the video CD control section 8, from the address read from the CD-ROM-XA header information register 42, the ENTRY. V
By referring to the CD file, the entry point number (number indicating the entry point from the beginning of the track) set in the currently playing track, that is, the index number (video index) is obtained. To be

Here, ENTRY. Video CD1 with entry points set in VCD file
The upper position is described by the track number and the frame address in ascending order of the track number and the frame address. Therefore, in the video CD control unit 8, the address read from the CD-ROM-XA header information register 42 is set to the ENTRY. The index number as the entry number of the entry point set in the currently reproduced track can be easily obtained only by comparing with the VCD file.

This scene number or index number (OSD data) is supplied to the video CD control section 8 (OSD processing section 2) when the remote controller 12 is operated in a predetermined manner.
In 4), it is converted into OSD display data and supplied to the superimposing unit 10. As a result, the superimposing unit 10 superimposes the scene number or index number on the image from the NTSC converting unit 6.

Next, display control of windows in the display control unit 50 will be described with reference to the flowchart of FIG. When the video CD 1 is attached to the apparatus and, for example, the reproduction of the first menu screen is started, the display control unit 5
0 opens a window and displays the menu screen and the cursor in the window. Then, in step S61, the video CD control unit 8 determines whether or not a new list is selected. That is, after the cursor is displayed on the monitor 17 together with the menu screen, it is determined whether or not any of the options displayed on the menu screen has been selected by the user operating the cursor, for example. . Alternatively, it is determined whether or not execution of a new list (transition of reproduction control to a new list) is instructed by operating the next key or numeric key, for example.

If it is determined in step S61 that a new list has been selected, the flow advances to step S62 to determine whether or not the new list is a lower hierarchy list than the list that has been executed so far. , Video CD control unit 8 determines.

Here, the determination process in step S62 is performed as follows, for example. That is, for example, in the video CD control unit 8, the video CD core processing unit 21 refers to the SRAM 9 in which the PBC (list) is stored, so that the list number of the new list (list I
D) is compared with the list number of the list that has been executed so far. Then, if the list number of the new list is larger than the list number of the list that has been executed so far, it is determined that the new list is a list in a lower hierarchy than the list that has been executed so far. Alternatively, the video CD core processing unit 21 may use the PBC
The hierarchical structure of the MPEG data recorded in the video CD 1 (the hierarchical structure of the list) is recognized by referring to the SRAM 9 in which the (list) is stored and analyzing the list in ascending order of the list numbers. Then, the video CD core processing unit 21 determines, based on the recognition result, whether or not the new list is in a lower hierarchy than the list that has been executed so far.

The list number of the new list can be obtained as follows, for example. That is, the list currently being executed describes the options on the menu screen or the list offsets (eg, next list offset, selection number offset, etc.) corresponding to, for example, the next key, numeric key, or other key. By multiplying the list offset by eight, the address to be set in the list pointer, that is, the start address of the list to be newly executed can be obtained. Therefore, the list described from the address is changed to PSD. VCD (This is already SR
(Stored in AM9), the list number of the list can be obtained.

If it is determined in step S62 that the new list is a list lower in hierarchy than the list that has been executed so far, step S63 is skipped and step S64 follows.
Is stored in the SRAM 9, and the process proceeds to step S65. In step S65, MPE is executed according to the new list.
When the G data is reproduced, the display control unit 50 opens a new window, and the reproduced MPEG data is displayed in the window. Further, the display control unit 50 moves the cursor to a predetermined position within the window. Then, the process returns to step S61, and the processing from step S61 is repeated again.

That is, for example, as shown in FIG.
When the window W1 is opened on the monitor 17 and the first menu screen is displayed therein, and when any of the options displayed on the menu screen is selected, the window W1-1 is displayed. By newly opening and executing the list corresponding to the selected option, the MPEG data corresponding to the list is displayed in the window W1-1. Furthermore, when the MPEG data displayed in the window W1-1 constitutes a menu screen and any one of the options displayed in the menu screen is selected, the window W1-1-1 is displayed. It is newly opened, and the MPEG data is displayed in the same manner as in the case described above.

The window to be newly opened is
It is possible to display the MPEG data in the upper layer of the MPEG data displayed in the window so that it does not overlap with an already opened window (hereinafter, appropriately referred to as the upper layer window) in which the MPEG data is displayed. Further, as shown in FIG. 10, it is also possible to display it in a window of a higher hierarchy which has been the active window until immediately before, or so as to overlap with a part of the window.

Since the window is basically smaller than the display screen of the monitor 17, it is necessary to reduce the reproduced MPEG data in order to display the MPEG data in such a window. This reduction processing is performed in the display control unit 50, for example.

On the other hand, if it is determined in step S62 that the new list is not in a lower hierarchy than the list that has been executed, the process proceeds to step S63, and the list ID of the new list is already stored in the SRAM 9. It is determined whether or not it is stored.

If it is determined in step S63 that the list ID of the new list is not stored in the SRAM 9, the process proceeds to step S64, and the same process as described above is performed.

Here, in the video CD core processing section 21,
In step S64 described above, the list ID of the list for controlling the reproduction of the MPEG data displayed in the opened window is set to SR in the table format, for example.
The window is managed by storing it in the AM 9 (hereinafter, a list ID is appropriately stored in a table format as a window hierarchy management table) and referring to this window hierarchy management table.

That is, in step S64, the video CD core processing unit 21 identifies information for identifying an opened window, for example, as shown in FIG. 11 (in the figure, W is a numeral or a numeral and a hyphen). Is attached) and a list ID of a list corresponding to the window (a list for controlling reproduction of MPEG data displayed in the window) are associated and registered in the window hierarchy management table. There is.

In the figure, windows W1-1 and W1 are displayed by selecting options 1, 2, 3, 4, and 5 on the menu screen displayed in window W1.
1-2, W1-3, W1-4, W1-5 are opened, and the MPEG data of the lower hierarchy of the menu screen displayed in the window W1 corresponding to each option is displayed in each of them. Also, by selecting option 1 on the menu screen formed by the MPEG data displayed in the window W1-3, the window W1
-3-1 is opened, and the window W1-3 is there.
The window hierarchy management table is displayed when the MPEG data (corresponding to option 1) in the lower hierarchy of the MPEG data displayed in (1) is displayed.

Returning to FIG. 9, when it is determined in step S63 that the list ID of the new list is stored in the SRAM 9 (registered in the window hierarchy management table), that is, in the new list. If the corresponding window is already open, step S
Proceeding to 66, the window is activated and the cursor is moved to a predetermined position in the window. Further, all the windows displaying the MPEG data corresponding to the list lower than the new list are closed.

Specifically, for example, as described with reference to FIG. 11, the windows W1, W1-1, W1-2, W1 are now described.
-3, W1-3-1, W1-4, W1-5 are open, and the window W1-3-1 is the active window, the window W1-3-
The MPEG data displayed in 1 constitutes a menu screen, and when the option corresponding to the list for controlling reproduction of the MPEG data displayed in the window W1 is selected on the menu screen, the window W1 is activated. With windows W1-1, W1-
2, W1-3, W1-3-1, W1-4 and W1-5 are all closed.

After that, the process proceeds to step S67, and the list ID of the list for controlling the reproduction of the MPEG data displayed in the closed window is deleted from the window hierarchy management table together with the identification information of the window associated with it. It

That is, for example, in the above case, in step S67, the windows W1-1, W1-2, W1 are displayed.
The list IDs corresponding to -3, W1-3-1, W1-4, and W1-5 are deleted together with the identification information.

Thereafter, the process returns to step S61, and it is again determined whether or not the list has been selected. And
When it is determined in step S61 that the list has not been selected, the process proceeds to step S68, and it is determined whether or not the close box of the window is instructed (operated) by the cursor. When it is determined in step S68 that the close box is not designated, the process returns to step S61. If it is determined in step S68 that the close box is instructed, the process proceeds to step S66, and the window instructed by the close box is closed. Further, in step S66, the window corresponding to the list in the upper hierarchy of the list for controlling the reproduction of the MPEG data displayed in the closed window is recognized and activated by referring to the window hierarchy management table, The cursor is moved to a predetermined position within the window.

Then, the process proceeds to step S67, and the list ID corresponding to the window closed in step S66 is deleted from the window hierarchy management table as described above, and the process returns to step S61.

By the above processing, when a plurality of windows are opened, the cursor is moved to any one of the windows and the window is designated, the display control unit 50 operates as described above. In addition, the window is activated instead of the window which has been activated so far. In this case, it is necessary to recognize the MPEG data to be displayed in the activated window and reproduce it. The MPEG data is recognized by referring to the window hierarchy management table and based on the list of list IDs associated with the identification information of the activated window.

Further, opening and closing of the window are performed by transmitting a command from the video CD control section 8 to the MPEG circuit section 4. That is, when opening a window, the command for opening the window (window setting command) from the video CD control section 8 to the MPEG circuit section 4 is, for example, identification information, display position, and size of the window to be opened. Are sent as parameters. When the window is closed, a command for closing the window is sent from the video CD control unit 8 to the MPEG circuit unit 4 together with the same parameters as those used when the window was opened.

When the VRAM of the display control unit 50 has only one display plane and the window to be closed overlaps another window, if the window is closed, the other window is closed. The overlapping part with and is, as it were, a chipped state. Therefore, in such a case, it is necessary to reproduce the MPEG data displayed in another window according to the list. On the other hand, the VRAM of the display control unit 50
However, in the case of having a plurality of display planes, the display planes corresponding to other windows may be displayed, so that it is not necessary to reproduce the MPEG data as described above.

Next, the window display control will be further described with reference to FIGS. 12 to 15 each show a selection list. In addition, in FIG. 12 to FIG. 15, the hexadecimal number described in the leftmost column indicates the start address of each selection list (therefore, it is set in the list pointer when the selection list is executed). Value). Further, the list number (list ID) of the selection list shown in FIGS.
Are respectively 20 (0014h) and 21 (0015
h), 22 (0016h) and 29 (001Dh).

For example, if the selection list shown in FIG. 12 is executed, the play item number (play item number) described therein is 1000.
Value of 03ECh (= 100)
4), so as described above, the segment play item (ITEM) corresponding to the value 5 obtained by subtracting 999 from it (ITEM
0005.DAT) (Segment Play Item # 5) (hereinafter, as appropriate, #
The segment play item corresponding to the segment play item no. #N) is reproduced. Further, a window is opened, and the segment play item no. 5 is displayed. Further, the list ID 20 is stored in the window hierarchy management table in association with the window identification information.

Segment play item no. After 5 is displayed, if the number key of "1" is operated, for example, se
Address 01A8h (= lection # 1 offset multiplied by 8)
A list whose start address is 0035h × 8), that is,
In this embodiment, the list ID shown in FIG. 13 is 21.
The playback control is transferred to the selection list. Also,
For example, if the number key of "2" is operated, selection # 2
Address 0268h (= 004Dh) that is eight times offset
The reproduction control is transferred to a list having a start address of x8), that is, in the present embodiment, a selection list with a list ID of 29 shown in FIG. Further, for example, when the next key is operated, a list having the address 0358h (= 006Bh × 8) obtained by multiplying the nextlist offset by 8 as the start address (in the embodiment of FIG. 12, the list ID is set to 39). Playback control is transferred to.

In the above case, the list ID of any list is the list I of the selection list of FIG.
Since it is larger than D, it is determined that the new list is a list in a lower hierarchy than the list that has been executed so far. Therefore, a new window is opened, and the MPEG data corresponding to the new list is displayed in that window. In addition, the list ID of the new list
And the identification information of the opened window are associated with each other and registered in the window hierarchy management table.

That is, for example, when the reproduction control is transferred to the selection list whose list ID is 21, there is
As shown in FIG. 13, the play item number (play ite
03EFh (= 1007) is described as the (m number), the segment play item no. 8 is played. Then, a new window is opened, and the segment play item no. 8 is displayed. Further, the list ID 21 is stored in the window hierarchy management table in association with the window identification information.

According to the selection list of FIG. 13, it is possible to select either "1" or "2" for the numeric keys. That is, FIG.
According to the selection list of the segment play item no. After the number 8 is displayed, for example, when the number key of "1" is operated, a list having the address 01C8h (= 0039h × 8) obtained by multiplying selection # 1 offset by 8 as the start address, that is, in the present embodiment , The reproduction control is transferred to the selection list with the list ID 22 shown in FIG. Also, for example, when the number key of “2” is operated, the address 01 obtained by multiplying selection # 2 offset by 8
The reproduction control is transferred to the list having the start address of E8h (= 003Dh × 8) (in the example of FIG. 13, the list ID is 23).

For example, if the reproduction control is transferred to the selection list with the list ID 22 shown in FIG. 14 by operating the number key "1", the list ID will be the list ID shown in FIG. Since it is larger than the list ID, a new window is opened. FIG.
In the selection list of, the play item number (pl
Since 04CAh (= 1226) is described as the ay item number), the segment play item no. 227 (= 12
26-999) is displayed.

Returning to the selection list of FIG. 12, if the number key of “2” is operated in the case where the reproduction control is performed according to this selection list, the list ID of FIG. The playback control is transferred to the 29 selection list. Since the list ID of the selection list of FIG. 15 is larger than the list ID of the selection list of FIG. 12, a new window is also opened. In addition, in the selection list of FIG. 15, the play item number (play itemnumber)
As 0005h (= a value in the range of 2 to 99)
Since 5) is described, the data recorded on the track whose track number is 5 is reproduced. This data is then displayed in the newly opened window.

Here, the track number in this case represents the physical address (physical address) of the track on the video CD 1. That is, the above-mentioned track number means the numbers sequentially assigned to the tracks formed from the inner circumference to the outer circumference of the video CD 1. In the video CD 1, a track having a physical address of 1 (hereinafter, a track having a physical address of #n is
Track no. The data including MPEG data (moving image, still image) as a segment play item is recorded in the track no. After 2,
Normally, MPEG data or the like which is played back sequentially is recorded, so that for general consumers (users), that is, when the track number is displayed by OSD, the physical address is a few. , 4, ... Are treated as tracks having track numbers 1, 2, 3, ....

On the other hand, by executing the selection list of FIG. 12, the segment play item no. 5
After is displayed, for example, if the return key is operated, the address 0000 obtained by multiplying the return list offset by 8
The reproduction control is transferred to the list having the start address of h (= 0000h × 8) (in the embodiment of FIG. 12, the list ID is set to 1).

In this case, since the list ID is smaller than the list ID of the selection list of FIG. 12, the new list (list having a list ID of 1) is not a list lower than the list currently executed. Is determined. Therefore, in this case, as described with reference to FIG. 9, the display control of the window is performed according to whether 1 is stored as the list ID in the window hierarchy management table.

As described above, when the display control of the window is performed using the list ID and the window hierarchy management table, it is not necessary to change the format of the video CD1 and therefore the compatibility of the video CD1 is not lost. .

Next, in the above embodiment, the display controller 5 is used by using the list ID and the window hierarchy management table.
I tried to control the display of the window at 0,
In addition to the window control, it is also possible to record window control data therefor on the video CD 1 and perform the window control according to the window control data.

FIG. 16 shows an example of the structure of a selection list added with window control data. The selection list is the selection list of FIG. 12 with window control data added.

The selection list has a list header (select), which has been a reserved area (reserved) in the past.
Information indicating whether or not the window control data is described in the selection list (hereinafter, appropriately referred to as window control data additional information) is described in a 1-byte portion following the ion list header). Further, when the window control data additional information indicates that the window control data is described, the selection list displays, for example, the MPEG data whose reproduction is controlled by the selection list at the end thereof. The size and the display position of the window opened at the time of writing are described as window control data.

In the present embodiment, the display position of the window is, for example, the upper left point of the window when the upper left coordinate of the display screen of the monitor 17 is (0, 0). It is designed to be described by coordinates.

FIG. 17 shows an example of the structure of a play list to which window control data is added. Also in the case of a play list, window control data is described in the same format as in the case of the selection list in FIG. 16, for example, at the end thereof. Since there is no reserved area in the play list, the window control data additional information is not described.

Video C on which the above list is recorded
When D1 is played back, in the video CD playback device,
The display control of the window is performed as follows. That is, when the video CD control unit 8 (video CD core processing unit 21) reads the selection list from the SRAM 9 and performs reproduction control according to the selection list, the window control data additional information is referred to and the window control is performed on the selection list. Determine if the data is described. Then, when the window control data is not described in the selection list, the video CD control unit 8 controls the control unit 40 (CP
A command similar to the conventional one is transmitted to U41). Therefore, in this case, the MPEG data is displayed on the entire display screen of the monitor 17, as in the conventional case.

On the other hand, when the window control data is described in the selection list, the video CD control section 8 performs the processing according to the flowchart of FIG. That is, first, in step S71, the window control data is read from the selection list. Then, in step S72, according to the window control data, via the control unit 40,
The display controller 50 is controlled. As a result, the display control unit 50 opens the window corresponding to the window control data and displays the MPEG data in the window.

Also, the video CD control unit 8 is
When a play list is read from the RAM 9 and reproduction control is performed according to the play list, it is determined whether window control data is described in the play list by referring to the end part of the play list. Then, corresponding to the determination result, the same processing as in the case of the above selection list is performed.

As in the case of using the above-mentioned list ID and window hierarchy management table, a new window is opened only when the reproduction control is transferred to a list lower in hierarchy than the currently executed list. In order to display the MPEG data whose reproduction is controlled by the list of the lower hierarchy in the window, for example, the window control data is described in the list to which the reproduction control is transferred when the next key and the numeric key are operated. You should leave it.

Also, the list for controlling reproduction is transferred,
If a new window is opened by this,
The video CD control unit 8 stores the identification information of the opened window in the SRAM 9 in association with the list ID of the list before transfer. Then, when a command to close the window is issued, the video CD control unit 8 performs control to close the window, then refers to the SRAM 9 and reproduces by a list of list IDs associated with the identification information of the window. Control is performed so that the window displaying the controlled MPEG data is the active window. Therefore, in this case, the reproduction control is transferred to the list having the list ID associated with the identification information of the closed window. However, when the window is closed, it is possible to describe in which list the reproduction control is to be transferred (which window is to be the active window).

In the above case, when the window control data is described in the list, the window is opened and the MPEG data is displayed in that window. However, when the window control data is described in the list However, for example, when the monitor 17 does not have a window display function, as in the conventional case, the monitor 1 is opened without opening the window.
It is possible to display MPEG data on the entire display screen of No. 7.

In the above case, the window control data is described in the list. However, the window control data may be recorded in the video CD 1 as a file other than the list, for example. It is also possible to do so.

As described above, when the window control data is described in the list to control the size and display position of the window, the list manages the parent, child, and grandchild relationships of the window. be able to.

By the way, lower layer MPEG data (MPEG data whose reproduction is controlled by a lower layer list)
When a new window is opened and MPEG data is displayed in the window when the playback of the video CD is instructed, the user can easily recognize the hierarchical structure of the video CD 1. In this case, as described above, it takes time from when the reproduction of the MPEG data is instructed until the MPEG data is displayed, which may make the user feel annoyed.

That is, in particular, when the MPEG data constitutes a menu screen having options, in order to instruct the reproduction of the MPEG data of the lower hierarchy, after the menu screen is displayed, the options on the menu screen are displayed. The user must immediately select the M
Even when it is desired to obtain the PEG data, it is necessary to wait until the MPEG data forming the menu screen is reproduced and decoded and displayed.

Therefore, the character data corresponding to the options on the menu screen is recorded on the video CD 1 so that the options can be selected even before the menu screen is displayed by the MPEG data. this,
It can be displayed before the menu screen.

FIG. 19 shows a configuration example of a selection list when character data is recorded on the video CD 1. The selection list shown in FIG. 12 is applied when the character data is recorded on the video CD 1.

This selection list has a list header (select), which has been a reserved area (reserved) in the past.
In the 1-byte portion following the ion list header), information indicating whether or not the character data of the menu screen formed by the MPEG data (play item) controlled by the selection list is recorded on the video CD 1 (hereinafter , Is referred to as character data additional information). Further, when the character data additional information indicates that the character data is recorded, the character data (the menu formed by the MPEG data controlled by the selection list for reproduction is formed at the end of the selection list). A pointer (hereinafter, appropriately referred to as a character data pointer) corresponding to an address where character data corresponding to the options on the screen is recorded is described.

In this embodiment, the character data pointer is, for example, 2-byte data, and the value obtained by multiplying the value by, for example, 8 is the address (start address) where the character data is recorded. It is made to become.
Therefore, in this case, the character data is recorded on the video CD 1 in units of 8 characters.

FIG. 20 shows another configuration example of the selection list when character data is recorded on the video CD 1. It should be noted that this selection list is obtained by applying the selection list of FIG. 16 to the case where character data is recorded on the video CD 1. In this example,
The window control data additional information and the character data additional information are described in the portion reserved as the reserved area, and the window control data and the character data pointer are further described in the end portion of the selection list.

Next, when the character data is recorded on the video CD 1, the reproducing process of the character data (hereinafter, appropriately referred to as character data reproducing process) will be described with reference to the flowchart of FIG. In this embodiment, the character data is recorded as a part of the PBC on the video CD 1
Therefore, the character data is recorded in, for example, INFO. Before playback control is started together with VCD files (video CD1
Immediately after the mounting), it is read into the SRAM 9.

When the reproduction control is transferred to the predetermined list, the video CD control section 8 refers to the additional character data information of the predetermined list in step S81 so that the character data (menu character data) is converted into the video data. It is determined whether or not it is recorded on CD1. If it is determined in step S81 that the character data is not recorded, the steps S82 and S83 are skipped, the character data reproduction process is terminated, and the normal reproduction process is performed (the MPEG data is reproduced according to a predetermined list). Be done).

If it is determined in step S81 that character data is recorded, step S82
SRA by referring to the character data pointer
The character data is read from M9 and supplied to the MPEG circuit unit 4 via the video CD control unit 8. Then, in step S83, the control unit 40 of the MPEG circuit unit 4 receives the character data and controls the display control unit 50 to display the character data. As a result, the character data is displayed on the monitor 17, and the character data reproduction process ends.

Since the character data is stored in the SRAM 9 in advance, it can be reproduced and displayed quickly. Therefore, the user can recognize the option on the menu screen configuring the MPEG data and make the selection without waiting for the MPEG data to be reproduced and displayed. That is, it is possible to provide the user with an environment with good response.

After the character data reproduction processing is completed, the video CD
The control unit 8 performs normal reproduction processing, that is, reproduction control according to a predetermined list, and thereby, reproduction and display of MPEG data (play item) described in the predetermined list.

Even during the reproduction of the MPEG data, the user can make a selection by referring to the already displayed character data corresponding to the option. That is, when the character data corresponding to the option is selected during the reproduction of the MPEG data, the video CD control unit 8 stops the reproduction of the MPEG data and controls the reproduction to the list corresponding to the selected option. Is designed to be migrated. Therefore, even if the reproduction of the MPEG data is started after the character data is displayed, the user does not have to wait for the reproduction of the MPEG data to end.

In addition, MPEG described in a predetermined list
When a menu screen composed of data is displayed, the character data previously displayed by this menu screen is erased by being overwritten, so to speak. Therefore, the display position and size of the character data are made to match the display position and size of the option corresponding to the character data on the menu screen. In this case, it is possible to prevent the user from feeling uncomfortable because the menu screen is displayed so as to be superimposed on the screen on which the character data is displayed. When the display position and size of the character data are made to match the display position and size of the option, the character data can be superimposed on the menu screen, for example.

[0177] Furthermore, MPE described in a predetermined list
When the reproduction time of the G data is long and it takes time until the menu screen having the options is finally displayed, only the minimum necessary portion of the MPEG data for displaying the menu screen is displayed. It is possible to play. In this case, the menu screen can be quickly displayed after the character data is displayed. The playback time of the MPEG data (segment play item) is INFO. It is described in the VCD, and the video CD control unit 8 displays this INFO. It can be recognized by referring to the VCD.

In addition to displaying the character data on the monitor 17, the video CD control unit 8 supplies the character data from the video CD core processing unit 21 to the voice synthesizing unit 29, and the voice synthesizing unit 29 corresponds to the character data. A synthetic sound can be generated. In this case, since the synthesized sound corresponding to the character data is output from the speaker 16, it is possible to operate the device even if the user has a visual impairment or does not see the display on the monitor 17, for example. Becomes

Further, in the video CD 1, in addition to character data corresponding to the option, data for explaining the option and for prompting an operation (hereinafter, appropriately referred to as explanation data) are recorded. In addition, it is possible to cause the voice synthesizer 29 to generate a synthesized voice corresponding to the explanation data and to output it from the speaker 16. In this case, since the voices explaining the options are output, it is possible to provide an environment in which it is easy to operate, for example, to a visually impaired user or a user unfamiliar with the operation.

Next, the MPE reproduced from the video CD 1
The aspect ratio of the screen constituted by the G data is not always one. That is, the aspect ratio of the screen composed of the MPEG data may be 4: 3 or 16: 9, for example. Therefore, it is possible to record the standard information on the MPEG data standard such as the aspect ratio as described above on the video CD 1.

22 to 24 show examples of the structure of a list in which, for example, data for recognizing the aspect ratio (hereinafter, appropriately referred to as wide ID data) is described as the standard information. Note that the list (playlist) of FIG. 22 is obtained by adding wide ID data to the playlist of FIG. 17, and the list (selection list) of FIG. 23 is added to the selection list of FIG.
The data is added. Further, the list (selection list) of FIG. 24 is obtained by adding wide ID data to the selection list of FIG.

In this embodiment, the wide ID data is 1-byte data and represents the aspect ratio of the screen formed by the MPEG data whose reproduction is controlled by the list in which it is described. There is.
That is, if the aspect ratio of the screen composed of MPEG data is 4: 3 or 16: 9, the wide I
The D data is, for example, 01h or 02h, respectively.

When the video CD 1 having the wide ID data recorded as described above is reproduced, the video CD control section 8 reads the wide ID data from the list,
The command corresponding to the value is transmitted to the display control unit 50 of the MPEG circuit unit 4. The display control unit 50 controls the aspect ratio of the screen formed by the MPEG data in response to the command. As a result, the monitor 17
Aspect ratio corresponding to wide ID data, MPEG
The data is displayed. Therefore, in this case, a screen having a correct aspect ratio is displayed (it is possible to prevent an image from being displayed with an unnatural aspect ratio).

Note that, for example, as shown in FIG. 22 and FIG. 24, when the window control data and the wide ID data are described in the list, the horizontal and vertical directions of the window defined by the window control data are displayed. When the ratio does not match the aspect ratio defined by the wide ID data, the window is controlled to have the aspect ratio defined by the wide ID data, for example.
However, in this case, the window can be controlled based on the window control data, ignoring the wide ID data.

In the video CD 1, standard information other than wide ID data, that is, a video signal output from, for example, a video CD reproducing device, is HDTV, NTSC, or E.
It is possible to record information for identifying which of the DTVII and the like is compliant. Further, the standard information is externally provided by superimposing it on the vertical blanking interval of the video signal output from the video CD reproducing device or from an output terminal (for example, Y / C connector) provided in the video CD reproducing device. It is also possible to output. In this case, a video CD on an externally connected VTR or monitor, for example.
It is possible to recognize the standard of the video signal output from the playback device.

Next, as described above, the monitor 17
A cursor is displayed for selecting an option on the menu screen and for other purposes. The display control of this cursor will be described.

When the VRAM of the display control unit 50 has only one display plane, the control unit 40 of the MPEG circuit unit 4 uses the monitor 17 (display plane).
The horizontal or vertical direction of the cursor is, for example, the x-axis or the y-axis, respectively, and the coordinates (x, y) of a point where a predetermined portion of the cursor (for example, the tip of the arrow when the cursor has an arrow shape) is located. ) Is recognized as the position of the cursor. The coordinates as the position of the cursor are output to the video CD control unit 8 as needed.

Then, in this case, the command (cursor operation signal) is issued from the video CD control unit 8 to the control unit 40.
Is transmitted, the control unit 40 causes the display control unit 50 to
Is controlled to move the cursor. The command is transmitted together with the coordinates of the cursor movement destination.

Even if there is only one display plane, the video CD control unit 8 controls the window address (identification information) so that the VRAM of the display control unit 50 described below has a plurality of display planes. It is possible to realize the same function as in the case of having. However, in this case, since the control unit 40 of the MPEG circuit unit 4 does not control the cursor in the window, this control is performed by the video CD control unit 8, for example.

When the VRAM of the display controller 50 has a plurality of display planes, for example, as shown in FIG. 25, the coordinates of the upper leftmost point of the monitor 17 are (0,
0), and the coordinates of the bottom right point is (100,10
0) is defined. This also applies to windows. As shown in FIG. 25, opened windows (in the figure, windows W1, W1-1, W1-
Regarding 1-1), the coordinate of the upper left point or the coordinate of the lower right point is defined as (0, 0) or (100, 100), respectively. Therefore, in this case,
Looking at each window, the position of the cursor is
It is expressed by so-called normalized coordinates in the range of (0,0) to (100,100).

In this case, the control unit 40 displays the cursor on the monitor 17 based on the identification information of the window in which the cursor is displayed and the coordinates at which the cursor is located (hereinafter referred to as normalized coordinates). The coordinates where is located are recognized. In order to specify the position of the cursor, the identification information and the normalized coordinates are output to the video CD control unit 8 as needed.

Also in this case, the cursor can be moved by transmitting a command (cursor operation signal) from the video CD control section 8 to the control section 40. That is, the control unit 40 controls the display control unit 50 in response to the command from the video CD control unit 8 to move the cursor.

Next, in order to be able to select the option displayed on the menu screen with the cursor, the display position where each option is displayed is the video CD.
It needs to be recognized by the control unit 8.
Therefore, the window in which the menu screen is displayed is divided horizontally or vertically into 10 equal parts, for example, as shown in FIG. 26, so that the window is divided into 100 areas, and each option is displayed on the video CD 1. Information regarding the area (hereinafter, appropriately referred to as area information) (for example, a number attached to each area in FIG. 26) is recorded in association with, for example, an option. In this case, the option selected by the cursor can be recognized by obtaining the area where the cursor is located and further obtaining the option associated with the area.

FIG. 27 shows a file in which the area information associated with the options is described in the video CD 1 (a data file in which the location of each key in the window is stored) (hereinafter, the display position will be changed as appropriate). An example of the structure of the list when an information file is recorded) is shown.
Note that this list (selection list) is applied when the display position information file is recorded on the video CD 1 of the selection list of FIG.

In this selection list, a pointer indicating the position on the video CD 1 where the display position information file is recorded (hereinafter referred to as a display position information file pointer) is described at the end of the selection list in FIG. Is configured.

When the reproduction control shifts to the list configured as described above, the video CD control section 8 refers to the display position information file pointer and reads the display position information file. Then, when the selection operation of the option using the cursor is performed, the video CD control unit 8 selects the selected option based on the position of the cursor on which the selection operation is performed and the description content of the display position information file. Recognize.

In the embodiment shown in FIG. 26, the regions are numbered in ascending order from 1 and the regions are specified by the numbers.
It is also possible to carry out by the position in the horizontal and vertical directions, that is, the xy coordinates. In this case x or y
If each coordinate is represented by 1 byte, the area is 2
It will be specified by byte data.

If the description content of the display position information file is referred to as display position information, the display position information in the embodiment shown in FIG.
PSD. The display position information file, which is a separate file from the VCD file, is described and recorded on the video CD 1.
SD. It is possible to describe the VCD file in association with the list using the display position information.

That is, FIG. 28 shows a configuration example of a file in which display position information is described in the same format as the selection list shown in FIG. In this file, the display position information (display position) of the options corresponding to the Privia key, the next key, the return key, the default key, the number key of "1", and the number key of "2",

Described in the part where on # 2 offset is described. This file is referenced, for example, when reproduction control is performed according to a list having the same value as the value described in the LIST ID part as the list ID.

In this case, as shown in FIG.
