From the control signals demodulated by the demodulation circuit 20 in the contents of the D disk 17, the presence / absence of data for forming a menu screen, which is a list display screen of title contents recorded in the DVD disk 17, is identified. Reference numeral 27 denotes a control circuit, which is a DVD disk 17 which is a component of the menu screen.
Arbitrary numbers correspond to the title display of each program in.

FIG. 8 shows the recorded contents of a DVD disk. FIG. 9 shows the structure of the title of a DVD disc.

FIG. 10 shows D in the case of the title configuration of FIG.
This shows a screen when the title menu data recorded on the VD disc is executed by the DVD reproducing device.

The contents of FIGS. 8, 9 and 10 are the same as those described in the section of "Prior Art", and will not be described.

The operation of the DVD reproducing apparatus configured as described above will be described below. Video and audio signals recorded on the DVD disk 17 are read by the optical pickup 18. The read signal is the amplification circuit 1
9 and is input to the demodulation circuit 20. Demodulation circuit 2
At 0, the video signal, audio signal, and control signal are demodulated from the input signal. The video signal and the audio signal among them are sent to the display device 21 to display a screen or the like. In the DVD disk 17, the VMGM_PGCI 7 and the menu data 8 shown in FIG.
The content of the screen 1 is a menu screen as shown in FIG.
The user can use this menu screen to set this DVD disc 1
It can be seen that the recorded contents of No. 7 are "A song", "B song", and "C song". When the user wants to watch “B song” from among them, the user can use “2” attached to the “B song” button.
Is designated by the input device 23. This numerical value input is sent from the input device 23 to the central control circuit 25, and the central control circuit 25 outputs the value of T in FIG.
The mechanism control circuit 22 is controlled so that the PTT with the PTT number of 3 in the TTU with the TU number of 1 is reproduced. The mechanism control circuit 22 determines that the optical pickup 18 has a PTU number of 3 in the TTU of the DVD disk 17 whose TTU number is 1.
Is moved to the position where the PTT is recorded, and the corresponding location is read. The read signal is the optical pickup 1
From 8, the video and audio signals are demodulated by a demodulation circuit 20 via an amplification circuit 19 and output to a display device 21.

On the other hand, the data structure identification circuit 26 includes a VMGM_PGC in the control signal demodulated by the demodulation circuit 20.
Confirm that I7 and menu data 8 exist. After this confirmation, the control circuit 27 assigns an arbitrary number to a button representing each song on the menu screen displayed as shown in FIG. For example, a numerical value “1” is assigned to the button of the song A, a numerical value “2” is assigned to the button of the song B, and a numerical value “3” is assigned to the button of the song C. The content of the assignment is sent from the control circuit 27 to the central control circuit 25. The central control circuit instructs the display circuit 24 to control the "B music" because the title being reproduced is "B music". The assigned numerical value “2” is displayed. FIG. 3 shows the display contents of the display circuit 24.

The assignment of numerical values to the buttons of each song on the menu screen by the control circuit 27 will be described in more detail with reference to FIG. FIG. 4 shows the menu screen of FIG.
I drew it small inside. Data for displaying such a menu screen image on the display device exists in the video entity information of the DVD disc. On the other hand, when the user selects the button 14 on this menu screen, the DVD playback device must play back the A tune registered in the button 14, but the data for that exists in the control information of the DVD disk. I do. That is, button information for each button in the menu screen exists as control information.
Button information includes button position information that indicates the physical position of the button on the screen, proximity button information that indicates which button is close to the top, bottom, left, and right of the button, and should be performed when the button is selected There is a button command indicating operation. As shown in FIG. 9, song A has a TTU with a TTU number of 1.
Is recorded in the PTT of 1 to 2 and the PTT number of the TTU with the TTU number of 1 is 1 in the button command in the button information of the button corresponding to the song A.
Play from PTT is written. Hence button 1
When 4 is selected, the song A is reproduced.

The control circuit 27 assigns a number to the button information. That is, in FIG. 4, the button information for the button displaying “Song A” is button information # 1.
Therefore, the numerical value to be assigned is “1”, and similarly, the button information for the button displaying “B music” is the button information #
2, so the numerical value to be assigned is “2”, and “C
Since the button information for the button displaying "Song" is button information # 3, the value to be assigned is "3". However, since the numerical value “1” in the screen display “1.A tune” of the button 14 cannot be recognized by the control circuit 27, it is not related to the numerical value “1” assigned to the button 14 by the control circuit 27. However, if there is a menu screen as shown in FIG. 4, if the buttons are arranged vertically, the values conventionally assigned to the buttons are 1, 2,.
It is often considered that the two coincide with each other.

As described above, according to the present invention, as in the above-described conventional DVD reproducing apparatus, for example, during reproduction of "B music",
The user has a TITLE (TTU) = 1, CHAP, which is a numerical value on the data structure on the disk which is unrelated to the user's feeling.
Instead of the display of TER (PTT) = 3, the display circuit can confirm the numerical value “2” assigned by the control circuit and representing the actual title number.

(Embodiment 2) FIG. 2 shows a DVD of the present invention.
The figure shows a configuration of the reproducing apparatus, and 17 is a DVD disk. Reference numeral 18 denotes an optical pickup for reading a signal recorded on the DVD disk 17 using a laser beam. An amplification circuit 19 amplifies a signal read by the optical pickup 18 to a required magnitude. A demodulation circuit 20 demodulates an output signal of the amplification circuit 19 to reconstruct original video, audio, control signals, and the like. A display device 21 reproduces the video and audio signals demodulated by the demodulation circuit 20 on a screen or a speaker. 2
Reference numeral 2 denotes a mechanism control circuit for controlling a disk motor (not shown) for rotating the optical disk 17 and the optical pickup 18 so that the recording signal of the DVD disk 17 can be read by the optical pickup 18 as described above. Reference numeral 23 denotes an input device, which is used when the user instructs the DVD playback device to perform an operation.
Various buttons such as "Stop playback" are provided. 24
Is a display circuit for displaying numerical values and the like. A central control circuit 25 controls the demodulation circuit 20 and the mechanism control circuit 22 based on various operations of the user from the input device 23 and various control information recorded on the DVD disk 17, and a display circuit 24. Outputs numerical values to be displayed. Reference numeral 26 denotes a data structure identification circuit, which is a DV read by the optical pickup 18.
From the control signals demodulated by the demodulation circuit 20 in the contents of the D disk 17, the presence / absence of data for forming a menu screen, which is a list display screen of title contents recorded in the DVD disk 17, is identified. Reference numeral 27 denotes a control circuit, which is a DVD disk 17 which is a component of the menu screen.
Arbitrary numbers correspond to the title display of each program in. Reference numeral 31 denotes a position identification circuit, which is a button of button information of each button as shown in FIG. 4 from data for forming a menu screen which is a list display screen of title contents recorded in the DVD disk 17. By reading the position information, the physical position of the button on the menu screen is identified.

The operation of the DVD reproducing apparatus configured as described above will be described below. A desired title is reproduced by reading a signal from the DVD disk 17, demodulating various signals by the demodulation circuit 20, and specifying a numerical value using the input device from the menu screen output to the display device. The method and the like are all the same as in the first embodiment, and a description thereof will be omitted.

The difference from the first embodiment resides in how numerical values are assigned to buttons on the menu screen of the control circuit 27. In the first embodiment, the numerical value to be assigned to the menu button is arbitrary, whereas in this configuration, it is assigned in ascending order from 1 according to a certain rule. That is, when the buttons are arranged in the vertical direction on the menu screen as shown in FIG. 5, a numerical value "1" is assigned to the top button, that is, the button 14 representing "Song A", and from top to bottom in order. , "B
“2” is assigned to the button 15 representing the “song”, “3” is assigned to the button 16 representing the “song C”, and “4” is assigned to the button 28 representing the “song D”. The method of assigning this numerical value is a commonly used assignment method when the buttons are vertically arranged, so that the display contents of the button, "1.A song"
Is very easy to match the numerical value “1” assigned by the control circuit. The same applies to “2” and thereafter.

To implement such an assignment, FIG.
The button position of the button information of each button as shown in FIG. 4 is selected from the data for configuring the menu screen which is the list display screen of the title contents recorded in the DVD disk 17 by the position identification circuit 31 of FIG. The information is read to identify the physical location of the button on the menu screen.
As a result, in the menu screen as shown in FIG. 5, the button at the top of the screen is a button representing "Song A" and then a button "Song B"
Are sent from the position information identification circuit 31 to the control circuit 27, and the control circuit 27 assigns a numerical value to the button as described above.

As described above, according to the present invention, as in the case of the conventional DVD reproducing apparatus, for example, during the reproduction of the "B music", the numerical value of the data structure on the disc is insensitive to the user's feeling. TITLE (TTU) = 1, CHAPT
Instead of the display of ER (PTT) = 3, the display circuit can confirm the numerical value representing the actual title number assigned by the control circuit.

(Embodiment 3) FIG. 2 shows a DVD of the present invention.
5 shows a configuration of a playback apparatus, which is described in Embodiment 2.
Therefore, the description is omitted. In addition, the operation is completely the same up to the display of the menu screen, so that this is also omitted. The difference from the second embodiment resides in how the control circuit 27 assigns numerical values to buttons on the menu screen. In the second embodiment, the numerical value to be assigned to the button on the menu screen is arbitrary. In the present configuration, the value is assigned in ascending order from 1 according to a certain rule. That is, when the buttons are arranged in a horizontal direction on the menu screen as shown in FIG. 6, a numerical value is assigned to the button from the leftmost button in the right direction in order. , "2" on the button 15 representing "B song", "3", "D" on the button 16 representing "C song".
“4” is assigned to the button 28 representing “song”. This method of assigning a numerical value is a commonly used assignment method when the buttons are horizontally arranged. Therefore, the numerical value assigned by the control circuit to “1. "1" is very easy to match. The same applies to “2” and thereafter. As described above, according to the present invention, as in the conventional DVD reproducing apparatus, for example, during reproduction of "B tune", TITLE which is a numerical value on a data structure on a disc which is unrelated to the user's feelings (TTU) = 1, CHAPTE
Instead of the display of R (PTT) = 3, the display circuit can confirm a numerical value representing the actual title number assigned by the control circuit.

(Embodiment 4) FIG. 2 shows a DV of the present invention.
This shows the configuration of the D playback device, and since the configuration is exactly the same as that of the second embodiment, the description is omitted. In addition, the operation is completely the same up to the display of the menu screen, so that this is also omitted. The difference from the second embodiment resides in how the control circuit 27 assigns numerical values to buttons on the menu screen. In the second embodiment, the numerical value to be assigned to the button on the menu screen is arbitrary. In the present configuration, the value is assigned in ascending order from 1 according to a certain rule. That is, when the buttons on the menu screen are arranged in a grid pattern as shown in FIG. 7, a numerical value “1” is assigned to the upper left button, that is, the button 14 representing “A song”, and the upper left to lower right direction is assigned. In the order, "2" is assigned to the button 15 representing "B song", "3" is assigned to the button 16 representing "C song", and so on.
Allocate "6" to the button 30 representing "F music".
This method of assigning numerical values is a commonly used assignment method when the buttons are arranged in a grid pattern.
It is very easy for “1” of “1.A tune”, which is the display content of the button, to match the numerical value “1” assigned by the control circuit. "2"
The same applies to the following. As described above, according to the present invention, as described above, for example, “B
TITLE (TTU) = 1, C, which is a numerical value on the data structure on the disc that is unrelated to the user's feeling while playing the "song"
Instead of the display of HAPTER (PTT) = 3, the display circuit can confirm the numerical value representing the actual title number assigned by the control circuit.

[0035]

As described above, according to the present invention, a display circuit provided in a reproducing apparatus for informing a user of a currently reproduced title number while reproducing a reproducing medium on which a plurality of programs are recorded. It is possible to provide an excellent video playback device that does not display a serial number or the like as data of the title on a playback medium that is meaningless to the user on the display of the user and does not give unnecessary misunderstanding to the user. I can do it.
