(First embodiment)
Hereinafter, an optical disk reproducing apparatus according to a first embodiment of the present invention will be described with reference to the drawings. In addition, embodiment shown below is an example and is not limited to this.
FIG. 1 shows a block diagram of an optical disc reproducing apparatus 20 according to the first embodiment of the present invention. 1 includes a disk drive 1, a moving picture decoder 2, a still picture decoder 3, a startup screen data memory (Random Access Memory) 4, a selector 5, a video encoder 6, and a video output terminal. 7, a CPU (Central Processing Unit) 8, an operator 9, an activation display data memory 12, and a video mixer 13.

  The disk drive 1 accepts insertion of an optical disk such as a DVD (Digital Versatile Disk) or CD (Compact Disk), and reads moving image data, still image data, audio data, management information, and the like recorded on the disk.

  The moving picture decoder 2 demodulates moving picture data and audio data read from the disk by the disk drive 1. The still picture decoder 3 demodulates still picture data read from the disc. The moving image data and still image data are recorded on the disc in a predetermined format such as MPEG (Moving Picture Experts Group), JPEG (Joint Photographic Experts Group) or the like. Of course, the moving picture decoder 2 and the still picture decoder 3 do not have to be provided separately, and may be configured as one decoder.

  The video encoder 6 converts the input signal into a format such as NTSC (National TV Standards Committee), PAL (Phase Alternating Line), etc., and outputs it from the video output terminal 7 as an image signal.

  The video output terminal 7 constitutes an output unit for connection to an external video monitor 10. The video monitor 10 may be any monitor that is independent or attached to another electronic device as long as it has a display such as a CRT (Cathode Ray Tube) screen, a liquid crystal screen, or a PDP (Plasma Display Panel). . Further, a projector may be used instead of the video monitor 10.

  The operation element 9 receives an operation input from a user and includes a remote controller and the like. The operator performs various inputs using, for example, a remote controller or through an OSD (On Screen Display) on the video monitor 10.

  The start screen data memory 4 stores a still image data file for displaying a start screen. The start-up screen data memory 4 is composed of a rewritable nonvolatile memory such as an EEPROM (Electrically Erasable Programmable ROM) or a flash memory.

  The startup screen data memory 4 stores screen image data created by the manufacturer of the optical disc playback apparatus 20 as a default. The user can change the startup screen display at any time by incorporating desired image data into the startup screen data memory 4. In this specification, the “start-up screen” refers to a screen that is automatically displayed when the optical disc playback apparatus 20 is started or when the operation is stopped for a predetermined time.

  For example, the user prepares a disc such as a CD-R (Compact Disk-Recordable) or CD-RW (CD-ReWritable) in which a still image file such as a JPEG file to be set on the startup screen is recorded. In these discs, for example, a commercially available material or a material that is created or downloaded by a user using a PC (Personal Computer) is recorded. The user plays this disc on the optical disc playback device 20 and selects an image of the start screen candidate through the OSD on the video monitor 10. The image signal reproduced from the disc is demodulated by the still image decoder 3 and written into the startup screen data memory 4 under the control of the CPU 8. FIG. 2 shows an example of still image data stored in the startup screen data memory 4.

  In order to prevent inadvertent memory rewriting and the like, the selection is performed by an operation different from the normal operation, for example, a plurality of switches of the operation element 9 are simultaneously pressed for a certain time. By this selection operation, a desired image file is stored in the startup screen data memory 4. The image previously captured by the user in the startup screen data memory 4 is deleted. However, the default startup screen image data is stored in, for example, another ROM, and can be returned to the default startup screen display by, for example, a reset operation.

  Returning to FIG. 1, the selector 5 receives output signals from the moving picture decoder 2, the still picture decoder 3, and the startup screen data memory 4, and selects and outputs any one of them under the control of the CPU 8. As will be described later, the CPU 8 selects an output signal from the startup screen data memory 4 at the time of startup, and selects an output signal from either the moving picture decoder 2 or the still picture decoder 3 at the time of reproducing the disc.

  The startup display data memory 12 is composed of a ROM, and stores startup display data displayed together with startup screen data when the startup screen is displayed. The activation display data is composed of still image data including specific characters (characters) such as the manufacturer's name, product name, and product series name, and is stored by the manufacturer of the optical disc playback apparatus 20. It is desirable that the selected character is easy to understand when it relates to the product attribute of the optical disc playback apparatus 20. FIG. 3 shows an example of image data stored in the activation display data memory 12. In the example shown in FIG. 3, a character (“ABC.CO.LTD”) indicating the name of the manufacturer of the optical disc playback apparatus 20 is included in the image.

  Returning to FIG. 1, the video mixer 13 is connected to the output of the selector 5, and is connected to the activation display data memory via the switch 14. During the startup screen display, the CPU 8 controls the switch 14 to be in the ON state. At this time, image data from the startup screen data memory 4 is input to the video mixer 13 via the selector 5, and image data from the startup display data memory 12 is input via the switch 14. The video mixer 13 synthesizes and outputs the two image data. For example, when the image shown in FIG. 2 is stored from the start screen data memory 4 and the image shown in FIG. 3 is stored from the start display data memory 12, the video mixer 13 synthesizes them. As a result, a startup screen as shown in FIG. 4 is displayed on the video monitor 10.

  The CPU 8 comprehensively controls the operation of the optical disk reproducing device 20 having the above configuration.

  Hereinafter, the startup operation of the optical disc playback apparatus 20 according to the first embodiment will be described with reference to the drawings. FIG. 5 shows a flowchart for explaining an example of the operation at the time of activation in the first embodiment. In the example shown below, the startup screen has been changed by the user before startup.

  First, the user activates the optical disc playback apparatus 20 (step S11). The CPU 8 selects the image data from the startup screen data memory 4 and controls the selector 5 to output it to the video mixer 13 (step S12). On the other hand, at the same time or before and after this, the CPU 8 controls to turn on the switch 14 and input the image data from the startup display data memory 12 to the video mixer 13 during the startup screen display (step S13). ).

  The video mixer 13 synthesizes the signal from the startup screen data memory 4 and the signal from the startup display data memory 12 (step S14). That is, the video mixer 13 generates an image signal obtained by synthesizing the image from the start screen data memory 4 and the image from the start display data memory 12 and outputs the image signal to the video encoder 6.

  The video encoder 6 converts the input signal into a format such as NTSC or PAL and outputs it as an image signal from the video output terminal 7. The image signal is displayed on the video monitor 10 connected to the video signal output terminal 7, and an activation screen is displayed (step S15). The startup screen is displayed as a standby screen as it is, for example, until the user instructs an operation.

  For example, the video mixer 13 combines the image data shown in FIG. 2 stored in the startup screen data memory 4 and the image data shown in FIG. 3 stored in the startup display data memory 12 into FIG. The image shown is synthesized and output.

  Thereafter, while the startup screen is displayed, the optical disc playback apparatus 20 starts playback of the disc inserted by the user or already loaded (step S16 in FIG. 5). That is, the signal recorded on the disk is read by the disk drive 1 and demodulated by the moving picture decoder 2 or the still picture decoder 3.

  When the reproduction signal can be output from the disc, the CPU 8 controls the selector 5 to select the demodulated signal and input it to the video mixer 13. At the same time, the CPU 8 controls the switch 14 to be turned off. Therefore, only the signal reproduced from the disc is output from the video mixer 13 to the video encoder 6. Thus, the signal from the disc playback is switched from the start screen signal and displayed on the video monitor 10 (step S17). This completes the operation at the time of startup. Thereafter, when the user stops reproduction for a predetermined time, the start screen may be displayed by the same operation.

  As described above, in the first embodiment, even when the start screen is changed to an image desired by the user, a screen with predetermined start display data added to the image is displayed. For this reason, even if the activation screen is changed to an arbitrary image, the user can immediately recognize that it is the activation screen, and a high usability of the user is realized by avoiding an erroneous operation or the like.

  For example, when it is used for business purposes, it is not always used by a person who changes the startup screen of the optical disc playback apparatus 20, but is often used by an unspecified person. For example, when used as library equipment, a library equipment manager usually changes the startup screen. In such a case, the library user may use such an optical disc playback device without knowing it, and misunderstand the start screen displayed on the screen as the disc playback screen.

  However, according to the optical disc playback apparatus 20 according to the present embodiment, no matter what image is displayed as the startup screen, the character (character) indicating the attribute of the optical disc playback apparatus 20 is preferably always on the startup screen. Is displayed. For this reason, the user (user) can easily recognize that the displayed screen is the startup screen, and an erroneous operation or the like is reliably prevented.

  On the other hand, the name of the manufacturer of the optical disc playback device 20, the model name, the model series name, etc. are usually displayed on the default startup screen, but the startup screen can be freely changed by the user. Does not display this screen. However, according to the present embodiment, the manufacturer's name and the like can always be displayed even if the screen is changed to an arbitrary screen. Therefore, it is very beneficial for the manufacturer because the advertisement function of the startup screen can be exhibited while improving the user's feeling of use.

  In the example shown in FIG. 1, the output of the selector 5 is input to the video mixer 13. However, as shown in FIG. 6, a signal obtained by synthesizing the startup screen data and the startup display data by the video mixer 13 may be input to the selector 5.

(Second Embodiment)
Hereinafter, an optical disk reproducing apparatus 20 according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 7 shows a block diagram of an optical disc reproducing apparatus 20 according to the second embodiment. In FIG. 7, the same components as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

  In the second embodiment, the image data stored in the activation display data memory 12 is configured to be changeable by the user, similarly to the activation screen data. That is, the startup display data memory 12 is composed of a rewritable memory, and is connected to the still picture decoder 3 and the CPU 8 as shown in FIG. 7, and can store arbitrary still picture data reproduced from the disk and demodulated. It is configured.

  In order to change the startup display data, first, a disc such as a CD-R or CD-RW in which startup display data to be combined with the startup screen is recorded is prepared. Such a disk can be manufactured using a predetermined application on a PC, for example. Specifically, a data file including a desired character (character string) can be created using a document application or a drawing application, and then converted into a format such as JPEG to create image data. Here, in order to facilitate screen composition, it is preferable that the background color of the character is represented by a blue background, that is, a character with a blue background.

  Next, while reproducing the created disc, an image to be changed to the startup display data is selected via the OSD on the monitor 10. For example, the change of the activation display data is activated by an operation such as pressing a plurality of switches of the operation element 9 simultaneously for a predetermined time in a combination different from the activation screen changing operation described above. When accepting an operation for changing the startup display data, the CPU 8 erases and writes the memory of the startup display data memory 12 and completes the change of the startup display data. The default startup display data is stored in, for example, another ROM and cannot be erased.

  As described above, in the second embodiment of the present invention, not only the startup screen data but also the startup display data can be changed to an image desired by the user. For this reason, in addition to being able to immediately recognize that it is a startup screen, the user can configure the startup screen by an arbitrary combination of the startup screen desired by the user and the startup screen character.

  This is useful, for example, when the display of a specific manufacturer's name or the like is not preferable for use in a public organization. Instead of the name displayed by default at the time of startup, a character indicating that the program is being started, such as “WAIT FOR A MOMENT.”, Is combined with the startup screen changed by the user (administrator) and displayed. Thereby, the administrator can change to a specific startup screen display, while the user (user) can easily recognize that the displayed screen is the startup screen.

  In the first and second embodiments, the activation display data memory 12 stores character data representing a character string. However, the activation display data memory 12 may store graphic image data such as a logo, a trademark, a mark, and a symbol, and may indicate the activation screen by superimposing the image data.

(Third embodiment)
Hereinafter, an optical disk reproducing device 20 according to a third embodiment of the present invention will be described with reference to the drawings. FIG. 8 shows a block diagram of an optical disc playback apparatus 20 according to the third embodiment. In FIG. 8, the same components as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 8, the optical disc playback apparatus 20 according to the third embodiment includes a character generator 16 that generates arbitrary character data. That is, in the third embodiment, still image data is not stored as activation display data, and predetermined character data generated by the character generator 16 is synthesized with the activation screen data in the video mixer 13 and output.

  Specifically, the character generator 16 is connected to an activation display data memory 12 composed of a writable nonvolatile memory. In the start display data memory 12, for example, character data relating to a character string such as a manufacturer's name is stored as text data. Since the stored character data is not image data but text data, the used capacity can be kept relatively low. When displaying the startup screen, the character generator 16 generates image data corresponding to the character string (character) stored in the startup display data memory 12 and outputs the image data to the video mixer 13. The video mixer 13 synthesizes the character data with the read start screen data and outputs it.

The character data stored in the activation display data memory 12 can be input and changed by the user from the operation element 9. That is, it is possible to generate an arbitrary character string desired by the user by using the optical disc reproducing apparatus 20 without using a separate PC.
For example, when the operation state of the apparatus is switched to a character input operation-dedicated state by pressing the switch of the operation element 9 a plurality of times, the video monitor 10 displays an alphabet, a Japanese syllabary, a character character, and an end key. . The user selects a desired character, generates a character string of a predetermined number of characters, and then selects a screen end key. The activation display data memory 12 stores the input character string.

  When the start screen is displayed next time, the image data in the start screen data memory 4 and the character character string created by the user are synthesized and output and displayed on the video monitor 10. Therefore, in addition to being able to immediately recognize that the user is the startup screen, it is possible to easily customize the character string desired by the user and configure an arbitrary startup screen.

  As described above, according to the third embodiment, the character data generated by the character generator 16 based on the text data stored in the activation display data 12 is synthesized and displayed during activation display. . For this reason, character data can be stored with a relatively small capacity. In addition, it is not necessary to create a boot display data disk for the boot screen, and the user can easily and directly customize a desired character string without using a PC to configure the boot screen.

  In the example shown in FIG. 8, the output of the selector 5 is input to the video mixer 13. However, as a matter of course, similarly to the configuration shown in FIG. 6, a signal obtained by synthesizing the start screen data and the character data by the video mixer 13 may be input to the selector 5.

  In addition, a program for realizing the above method may be read by an optical disc reproducing device, a computer device, or the like, and a series of processes may be executed. In this case, the program is not only incorporated in the hardware in advance, but also recorded on a removable recording medium such as a flexible disk, a CD-ROM, a DVD, or a semiconductor memory, and read from the recording medium to an optical disk playback device or the like. May be. Further, such a program may be downloaded to a computer device via a network such as the Internet, stored in a recording medium, and installed in an optical disk reproducing device or the like. Furthermore, by providing a communication processing unit in the optical disc playback apparatus or the like, it is possible to download and install directly through a network.

  INDUSTRIAL APPLICABILITY The present invention is useful for technologies such as an optical disk playback device and a computer device that allow a user to change a startup screen and a standby screen.
