Description

  The present invention relates to an optical disc system including an optical disc device for setting an optical disc such as a CD and a DVD, reproducing and recording, and a television receiver for displaying the set state of the optical disc with an OSD.

  2. Description of the Related Art Conventionally, optical disc apparatuses that reproduce video and audio recorded on optical discs such as CDs and DVDs and record data have been put into practical use and have been generalized.

  Among such optical disk apparatuses, there is an apparatus that adopts a slot-in mechanical system in which an optical disk can be loaded and unloaded by a one-touch operation without opening and closing a lid (tray).

  Although the optical disk device adopting this slot-in mechanism method has an advantage that the optical disk can be inserted and removed by one-touch operation, the user forgets to set the optical disk and sets a new optical disk in duplicate. There was a problem. Since the two optical disks are overlapped by setting the optical disks in an overlapping manner, one of the optical disks damages the back surface (recording surface) of the other optical disk. Naturally, scratches on the recording surface adversely affect reproduction / recording of the optical disk.

  Therefore, an optical disc apparatus described in Patent Document 1 has been proposed.

This optical disk apparatus displays whether or not an optical disk is set on a display unit built in the apparatus.
Japanese Patent Laid-Open No. 2002-50168

  However, in Patent Document 1, the display unit built in the device is generally smaller than a television screen. Further, when the character is displayed on the display unit, the character is very small. Therefore, the character is difficult to understand at first glance for the user.

  Therefore, even if the display unit displays whether or not an optical disk is set, there is still a problem that the user does not notice the display and sets a new optical disk in duplicate.

  The present invention is intended to solve such a conventional problem, and when an optical disc is set in the optical disc apparatus, the set state of the optical disc is displayed on the OSD of the television receiver, and the set state is shown to the user at a glance. It is an object of the present invention to provide an optical disc system that can be understood.

The optical disc system of the present invention has the following configuration in order to solve the above problems.
(1) an optical disc apparatus having reading means for irradiating an optical disc set in the apparatus main body with laser light and reading data recorded in a data area of the optical disc;
In an optical disc system comprising a television receiver having display means for displaying a desired OSD,
The optical disc device detects whether or not an optical disc is set in the main body of the device, and generates a DiskIn display signal as a signal indicating the set state of the optical disc when the detecting portion detects the set state of the optical disc. And a signal generation / transmission means for transmitting the DiskIn display signal to the television receiver,
When the television receiver receives the DiskIn display signal from the signal generation / transmission means, the television receiver instructs the display means to display a DiskIn image on the OSD as an image representing a set state of the optical disc. Display instruction means.

  In this configuration, the DiskIn image is a mark or character representing a state where the optical disc is set in the optical disc apparatus. The optical disk is, for example, a DVD or a CD.

  This configuration is mainly assumed to be used in the television mode instead of the optical disc mode. The optical disc mode is a mode in which the optical disc apparatus reads video and audio recorded on the optical disc and reproduces them on the television receiver. The television mode is a mode in which the television receiver receives a television broadcast signal and outputs video and audio of a selected channel.

  That is, this configuration is characterized in that when the video of the selected channel is displayed on the screen, the DiskIn image is displayed on the screen by the OSD.

As described above, the DiskIn image can be displayed on the OSD of the television receiver. Therefore, since the user can understand the set state of the optical disk at a glance, a new overlapping setting of the optical disk can be prevented.
(2) The display instructing unit instructs the display unit to erase the display of the DiskIn image when a predetermined time elapses, and displays the DiskIn image when a predetermined redisplay condition is satisfied. Is instructed to the display means.

  In this configuration, the fixed time is, for example, 5 seconds. For a certain period of time, when a channel switching operation of the television receiver is performed, or when a volume switching operation of the television receiver is performed, the OSD indicating that these operations are performed disappears after being displayed. It should be the same as the time until.

  The re-display condition is, for example, that a channel switching operation of the television receiver is performed, a volume switching operation of the television receiver is performed, or that the television receiver enters a commercial. Since a DiskIn image is displayed when a channel switching operation or the like is performed or when a commercial is entered, the DiskIn image can be displayed at an appropriate timing.

  In this configuration, for example, each time a channel switching operation of the television receiver is performed, the DiskIn image is displayed, and the DiskIn image is erased every time a fixed time elapses from the display of the DiskIn image. On the contrary, every time a certain period of time elapses from the display of the DiskIn image, the DiskIn image is displayed every time a channel switching operation or the like of the television receiver is performed even if the DiskIn image is deleted.

  More specifically, when a channel switching operation or the like of the television receiver is performed, the DiskIn image is displayed. When a certain time has elapsed from the display of the DiskIn image, the DiskIn image is erased. When the channel switching operation of the television receiver is performed again, the DiskIn image is displayed again. When a certain time has elapsed from the display of the DiskIn image, the DiskIn image is erased again.

  In (1) above, once the DiskIn image is displayed, it remains on the screen for a while, which may be annoying to the user. However, here, the channel switching operation of the television receiver is performed. Each time the DiskIn image is displayed, the DiskIn image is erased every time a fixed time elapses from the display of the DiskIn image. Therefore, the DiskIn image can be displayed on the screen appropriately.

As described above, the DiskIn image can be displayed on the screen at an appropriate timing and appropriately. Therefore, the user does not feel bothered.
(3) The display means is an OSD that displays that the operation has been performed when a channel switching operation of the television receiver is performed or when a volume switching operation of the television receiver is performed. The DiskIn image is displayed adjacently.

In this configuration, the DiskIn image is conspicuous by displaying the OSD and the DiskIn image adjacent to each other. Therefore, the user can see the set state of the optical disk at a glance.
(4) When the power of the television receiver is turned off, the display means displays the DiskIn image on the screen of the display means before the power of the television receiver is turned off.

In this configuration, the DiskIn image is conspicuous by displaying the DiskIn image large on the screen of the display means before the television receiver is turned off. Therefore, the user can see the set state of the optical disk at a glance.
(5) When the detection unit detects an unset state of the optical disc, the signal generation / transmission unit generates a DiskIn display release signal as a signal indicating the unset state of the optical disc, and the DiscIn display release signal is used as the television receiver. To
The display instructing unit instructs the display unit not to display the DiskIn image when the television receiver receives the DiskIn display cancel signal from the signal generating / transmitting unit.

  In the unset state, the problem of duplicate set does not occur. Therefore, when the television receiver receives the DiskIn display cancellation signal from the signal generation / transmission means, that is, when the optical disk is not set, the DiskIn image is not displayed. Then, the DiskIn image is not displayed until the television receiver receives the DiskIn display signal again from the signal generation / transmission means, that is, until the optical disk is set again.

  In (2) above, every time a certain period of time has elapsed since the display of the DiskIn image, the DiskIn image was displayed every time a channel change operation of the television receiver was performed even though the DiskIn image was deleted. Then, even if the channel switching operation of the television receiver is performed, the DiskIn image is not displayed until the optical disc is set again.

  According to the present invention, since the user can see the set state of the optical disk at a glance, it is possible to prevent a new overlapping setting of the optical disk.

  Hereinafter, an optical disk system according to an embodiment of the present invention will be described.

  FIG. 1 is a system configuration diagram of an optical disc system according to an embodiment of the present invention. When the optical disc system 1 detects the set state of the optical disc 20 (see FIG. 2 described later), the optical disc apparatus 10 transmits a DiskIn display signal to the TV 100 as a signal indicating the set state of the optical disc 20 (see FIG. 1 (5)). And a TV (television) 100 that displays a DiskIn image based on the DiskIn display signal on an OSD (on-screen display).

  The optical disc 20 is, for example, a CD or a DVD. The DiskIn image is a mark or a character representing a state where the optical disc 20 is set in the optical disc apparatus 10. In FIG. 1, the DiskIn image is “DiskIn”, but “Disk is inserted” or the like may be used.

  The optical disk apparatus 10 is an apparatus adopting a slot-in mechanical system, and includes an optical disk slot 16 for setting the optical disk 20.

  The TV 100 includes a CRT 106A that displays a DiskIn image using an OSD.

  The above configuration is mainly assumed to be used in the television mode instead of the optical disc mode. The optical disc mode is a mode in which the optical disc apparatus 10 reads video and audio recorded on the optical disc 20 and reproduces them on the TV 100. The TV mode is a mode in which the TV 100 receives a TV broadcast signal and outputs video and audio of a selected channel.

  That is, this configuration is characterized in that when the video of the selected channel is displayed on the CRT 106A, the DiskIn image is displayed on the CRT 106A by the OSD.

  When the optical disc 20 is not set, the optical disc apparatus 10 transmits a DiskIn display release signal to the TV 100 as a signal indicating the unset state of the optical disc 20 (see FIG. 1 (5) ′). As a result, the characters “DiskIn” disappear from the CRT 106A.

  FIG. 2 is a block diagram of an optical disc apparatus used in the optical disc system according to the embodiment of the present invention. FIG. 3 is a block diagram of a television used in the optical disc system.

  As shown in FIG. 2, the optical disk apparatus 10 reads the data recorded in the data area of the optical disk 20 set in the apparatus main body and the control unit 11 that controls the operation of the apparatus main body, and the read signal RF A reading unit 12 for outputting a signal; an optical disc reproducing unit 13 for processing the RF signal to extract and output video and audio data; and a reproduced video signal and a reproduced audio signal by decoding the video and audio data. A reproduction signal generation unit 14 that generates and outputs, and an output terminal 15 that outputs a signal to the TV 100 are provided.

  The reading unit 12 is provided with a known pickup head. The pickup head is provided with an LD (laser diode) that is a light source, an objective lens that condenses the laser light emitted from the LD, a four-divided light receiving element that detects reflected light from the optical disc 20, and the like. ing.

  The pickup head of the reading unit 12 detects reflected light from the optical disk 20 with a known four-divided light receiving element, converts the reflected light into an electrical signal, and outputs an RF signal. The RF signal is a read signal for data recorded on the optical disc 20. The reading unit 12 amplifies the RF signal with an RF amplifier and inputs the amplified RF signal to the optical disc reproducing unit 13.

  The optical disc playback unit 13 processes the RF signal to extract video and audio data, and inputs the video and audio data to the playback signal generation unit 14. Here, the extracted data is encoded by, for example, MPEG.

  The reproduction signal generation unit 14 decodes video and audio data to generate a reproduction video signal and a reproduction audio signal, and outputs them to the TV 100 via the output terminal 15A and the output terminal 15B.

  As shown in FIG. 3, the TV 100 includes a control unit 101 that controls the entire TV 100, a tuner 102 that processes a television broadcast signal, and a video / audio switching unit that separates and extracts a video signal and an audio signal from the television broadcast signal. 103, an OSD processing unit 104 that superimposes a desired OSD on the video signal, a video processing unit 105 that processes the video signal and outputs the video, a display unit 106 that displays the video, and processes the audio signal and outputs audio A sound processing unit 107 that outputs sound, a sound output unit 108 that outputs sound, and an operation unit 109 that allows the user to adjust the volume and the like.

  The operation unit 109 includes a remote control signal detection unit (not shown). When a command such as power ON / OFF, channel switching, volume adjustment, non-display of “DiskIn” characters is input to the remote control signal detection unit from the outside using the remote control 121, the remote control signal detection unit Receives a command signal from the remote controller 121 and transmits it to the control unit 101.

  The control unit 101 controls power ON / OFF, channel switching, volume adjustment, non-display of “DiskIn” characters, and the like according to a command input by the user via the operation unit 109 or the remote controller 121 (described later). FIG. 5 s103, s105).

  The video / audio switching unit 103 receives the reproduced video signal and the reproduced audio signal output via the output terminal 15A and the output terminal 15B of the optical disc apparatus 10 via the input terminal 110A and the input terminal 110B. Then, the video / audio switching unit 103 outputs a reproduced video signal and a reproduced audio signal. The reproduced video signal is input to the video processing unit 105 via the OSD processing unit 104.

  The OSD processing unit 104 superimposes characters or figures on the playback video signal based on the control signal given from the control unit 101.

  The video processing unit 105 extracts the video by processing the playback video signal output from the video / audio switching unit 103 and displays the video on the display unit 106.

  The audio processing unit 107 extracts the audio by processing the reproduced audio signal output from the video / audio switching unit 103, and outputs the audio from the audio output unit 108.

  Thus, the optical disc apparatus 10 reads the video and audio recorded on the optical disc 20 and reproduces them on the TV 100 (optical disc mode).

  On the other hand, in the television mode, the TV 100 outputs video and audio of the selected channel as follows.

  The tuner 102 extracts the television broadcast signal of the selected channel from the television broadcast signal received by the antenna 120 and outputs it.

  The video / audio switching unit 103 separates and extracts the television broadcast signal output from the tuner 102 into a video signal and an audio signal, and outputs them. The video signal is input to the video processing unit 105 via the OSD processing unit 104.

  The OSD processing unit 104 superimposes characters or figures on the video signal based on the control signal given from the control unit 101.

  The video processing unit 105 processes the video signal output from the video / audio switching unit 103 to extract a video, and displays the video on the display unit 106.

  The audio processing unit 107 extracts the audio by processing the audio signal output from the video / audio switching unit 103 and outputs the audio from the audio output unit 108.

  As described above, the TV 100 receives the TV broadcast signal and outputs the video and audio of the selected channel (TV mode).

  Here, the reading unit 12 corresponds to “reading means” and “detection means” of the present invention. The control unit 11 corresponds to “signal generation / transmission means” and “display instruction means” of the present invention. The OSD processing unit 104, the video processing unit 105, and the display unit 106 correspond to the “display unit” of the present invention.

  FIG. 4 is a flowchart showing an operation performed by the control unit in the television mode in the optical disc apparatus used in the optical disc system according to the embodiment of the present invention.

  The control unit 11 of the optical disc apparatus 10 determines whether or not the TV 100 is turned on (s1, see FIG. 2 (1), see FIG. 3 (1)). This determination is made based on whether or not the control unit 101 of the TV 100 is operating via the output terminal 15C and the input terminal 110C of the TV 100. The reason for this determination is that the control unit 11 cannot transmit the DiskIn display signal to the TV 100 unless the TV 100 is turned on (see FIG. 1 (5), FIG. 2 (5)). )reference).

  If it is determined that the power source of the TV 100 is turned on, the control unit 11 determines whether or not the optical disc 20 is set in the apparatus main body (s2). Therefore, the control unit 11 instructs the reading unit 12 to detect whether or not the optical disc 20 is set in the apparatus main body (see FIG. 2 (2)).

  The reading unit 12 detects whether or not the optical disc 20 is set in the apparatus main body. This detection is performed by irradiating laser light from the pickup head and detecting whether or not the reflected light is detected. If the reading unit 12 can detect the reflected light, the reading unit 12 converts the reflected light into an electric signal and transfers it to the control unit 11 (see FIG. 2 (3)). The control unit 11 can determine that the optical disc 20 is set in the apparatus main body by transferring the electric signal.

  If it is determined in s2 that the optical disc 20 is not set in the apparatus main body, the control unit 11 returns to s2 and continues the processing.

  On the other hand, when it is determined that the optical disc 20 is set in the apparatus main body, that is, when the reading unit 12 detects the set state of the optical disc 20, the control unit 11 generates a DiskIn display signal as a signal indicating the set state of the optical disc 20. (S3, see FIG. 2 (4)).

  Then, the control unit 11 transmits the DiskIn display signal to the TV 100 via the output terminal 15C (s4, see FIG. 1 (5), see FIG. 2 (5), see FIG. 3 (5)).

  The control unit 11 determines whether or not the optical disc 20 is set in the apparatus main body (s5). The determination of s5 is the same as the determination of s2 (see FIGS. 2 (2) and (3)).

  If it is determined that the optical disc 20 is set in the apparatus main body, the control unit 11 returns to s5 and continues the processing.

  On the other hand, when it is determined that the optical disc 20 is not set in the apparatus main body, that is, when the reading unit 12 detects an unset state of the optical disc 20, the control unit 11 cancels the DiskIn display as a signal indicating the unset state of the optical disc 20. A signal is generated (see s6, Fig. 2 (4) ').

  Then, the control unit 11 transmits the DiskIn display cancellation signal to the TV 100 via the output terminal 15C (s7, see FIG. 1 (5) ′, see FIG. 2 (5) ′, see FIG. 3 (5) ′. ), Return to s1, and continue the process.

  FIG. 5 is a flowchart showing an operation performed by the control unit in the television mode in the television used in the optical disc system according to the embodiment of the present invention.

  The control unit 101 determines whether a DiskIn display signal has been received from the optical disc apparatus 10 via the input terminal 110C (s101, see FIG. 3 (5)). When determining that the DiskIn display signal has not been received from the optical disc apparatus 10, the control unit 101 returns to s101 and continues the processing.

  On the other hand, when determining that the DiskIn display signal is received from the optical disc apparatus 10, the control unit 101 provides the OSD processing unit 104 with a control signal for displaying the characters “DiskIn” on the OSD (s102, FIG. 3 ( See 6)). Then, the OSD processing unit 104 superimposes the characters “DiskIn” on the video signal. The video processing unit 105 displays the characters “DiskIn” on the display unit 106. As a result, the characters “DiskIn” are displayed on the CRT 106A (see FIG. 1).

  The control unit 101 determines whether an instruction not to display the characters “DiskIn” is input by the operation unit 109 or the remote controller 121 (s103). This determination assumes that the user erases the characters “DiskIn” using the operation unit 109 or the remote controller 121 because the user thinks that the characters “DiskIn” are displayed on the CRT 106A. .

  If it is determined that an instruction not to display the characters “DiskIn” is input, the control unit 101 provides a control signal for not displaying the characters “DiskIn” on the OSD to the OSD processing unit 104 (s105, FIG. 3 (6) ′), the process returns to s101 and continues. Then, the OSD processing unit 104 stops superimposing the characters “DiskIn” on the video signal. As a result, the characters “DiskIn” disappear from the CRT 106A.

  The character “DiskIn” is not displayed on the CRT 106A until the DiskIn display signal is received again from the control unit 11 of the optical disc apparatus 10 in s101.

  On the other hand, if it is determined in s103 that an instruction not to display the characters “DiskIn” has been input, the control unit 101 determines whether a DiskIn display release signal has been received from the control unit 11 of the optical disc apparatus 10 or not. (S104). If it is determined that the DiskIn display cancel signal has not been received, that is, if it is determined that the optical disc is in the set state, the process returns to s103 and the processing is continued.

  As with the DiskIn display signal, the control unit 101 generates the control signal by processing the DiskIn display release signal as shown in (6) of FIG.

  If it is determined that the DiskIn display cancellation signal has been received, the control unit 101 gives a control signal for not displaying the characters “DiskIn” on the OSD to the OSD processing unit 104 (s105, see FIG. 2 (6) ′). , Return to s101 and continue processing. Then, the OSD processing unit 104 stops superimposing the characters “DiskIn” on the video signal. As a result, the characters “DiskIn” disappear from the CRT 106A. When the DiskIn display cancellation signal is received, the optical disk is in an unset state. In this unset state, the problem of duplicate setting does not occur, so the characters “DiskIn” are deleted.

  The character “DiskIn” is not displayed on the CRT 106A until the DiskIn display signal is received again from the control unit 11 of the optical disc apparatus 10 in s101, that is, until the optical disc 20 is set again.

  As described above, the DiskIn image can be displayed on the OSD of the TV 100. Accordingly, since the user can see the set state of the optical disc 20 at a glance, it is possible to prevent duplicate setting of new optical discs.

  Hereinafter, an optical disk system according to another embodiment of the present invention will be described. The configuration of the optical disc system 200 according to another embodiment of the present invention is the same as that of the optical disc system 1 according to the above embodiment. The optical disc system 200 includes an optical disc device 10 and a TV 201. The configuration of the TV 201 is the same as that of the TV 100.

  FIG. 6 is a flowchart showing an operation performed by the control unit in the television mode in the television used in the optical disc system according to another embodiment of the present invention. FIG. 7 is a diagram showing an OSD displayed on the screen at the time of channel switching in the television used in the optical disc system. FIG. 8 is a diagram showing an OSD displayed on the screen immediately before the power is turned off in the television used in the optical disc system.

  s201 is the same process as s101.

  If it is determined that the DiskIn display signal is received from the optical disc apparatus 10, the control unit 101 determines whether the user has input the TV 201 channel switching, the TV 201 volume adjustment, or the like using the operation unit 109 or the remote controller 121. (S202).

  When determining that the channel switching of the TV 201 has been input, the control unit 101, when the channel switching operation of the TV 201 is performed, displays an OSD (8CH in FIG. 7) and “DiskIn” indicating that the operation has been performed. A control signal for displaying the character adjacently is given to the OSD processing unit 104 (s203, see FIG. 3 (6)). Then, the OSD processing unit 104 superimposes the characters “DiskIn” on the video signal at a position adjacent to 8CH. The video processing unit 105 displays 8CH and the character “DiskIn” adjacent to each other on the display unit 106. Thereby, 8CH and the characters “DiskIn” are displayed adjacent to each other on the CRT 106A (see FIG. 7).

  Therefore, the character “DiskIn” is conspicuous by displaying adjacent to 8CH. Therefore, the user can see the set state of the optical disk at a glance.

  Note that when an adjustment of the volume of the TV 201 or the like is input, the OSD for displaying that the operation has been performed and the character “DiskIn” are adjacent to each other, as in the case of switching the channel of the TV 201. Displayed. In addition, the control unit 101 may determine whether or not the commercial has been moved in s202, and the character “DiskIn” may be displayed during the commercial in s203.

  As described above, when a channel switching operation or the like is performed or when a commercial is entered, the characters “DiskIn” are displayed, so that the characters “DiskIn” can be displayed at an appropriate timing.

  The control unit 101 determines whether or not a certain time has elapsed (s204). The fixed time is, for example, 5 seconds. For a certain period of time, when a channel switching operation of the TV 201 is performed or when a volume switching operation of the TV 201 is performed, an OSD (8CH in FIG. 7) indicating that these operations have been performed is displayed. It should be the same as the time until it disappears.

  In s204, after a predetermined time has elapsed, the control unit 101 gives a control signal for deleting the character “DiskIn” to the OSD processing unit 104 (see s205, FIG. 3 (6) ′). Then, the OSD processing unit 104 stops superimposing the characters “DiskIn” on the video signal. As a result, the characters “DiskIn” disappear from the CRT 106A.

  The characters “DiskIn” are not displayed on the CRT 106A until a predetermined redisplay condition is satisfied or until a DiskIn display signal is received again from the control unit 11 of the optical disc apparatus 10 in s201. The re-display condition is, for example, that a channel switching operation of the TV 201 is performed, a volume switching operation of the TV 201 is performed, or that the TV 201 enters a commercial. Affirmative determination in s202 corresponds to a redisplay condition. In FIG. 6, the redisplay condition is satisfied when s206 determination is negative, s207 determination is negative, and s202 is positive.

  The control unit 101 determines whether an instruction not to display the characters “DiskIn” is input by the operation unit 109 or the remote controller 121 (s206). This determination is the same as in s103.

  If it is determined that an instruction not to display the characters “DiskIn” is input, the control unit 101 returns to s201 and continues the processing. The characters “DiskIn” are not displayed on the CRT 106A until the DiskIn display signal is received again from the control unit 11 of the optical disc apparatus 10 in s201.

  On the other hand, if it is determined in s206 that an instruction not to display the characters “DiskIn” is input, the control unit 101 determines whether or not a DiskIn display release signal has been received from the control unit 11 of the optical disc apparatus 10. (S207). This determination is the same as in s104. If it is determined that the DiskIn display cancellation signal has not been received, that is, if it is determined that the optical disk is in the set state, the process returns to s202 and the processing is continued.

  A series of steps starting from the positive determination of s202, repeating the positive determinations of s203, s204, negatively determining s205, s206, and negatively determining s207, and repeating the determination positive (redisplay condition) of s202 has a repetitive structure. In this repetitive structure, the character “DiskIn” is displayed every time the channel switching operation of the TV 201 is performed, and the character “DiskIn” is erased every time a certain time elapses from the display of the character “DiskIn”. It is in a state. Conversely, every time a certain amount of time has elapsed since the display of the “DiskIn” character, even if the “DiskIn” character is deleted, the “DiskIn” character is displayed each time the channel switching operation of the TV 201 is performed. It is also in a state.

  More specifically, when a channel switching operation or the like of the TV 201 is performed (Yes in s202), the characters “DiskIn” are displayed (s203), and if a certain time has elapsed from the display of the characters “DiskIn” (s204). If the determination is affirmative, the character “DiskIn” is deleted (s205). Then, when the channel switching operation of the TV 201 is performed again after the negative determination of s206 and the negative determination of s207 (determination of determination in s202 (redisplay condition)), the characters “DiskIn” are displayed again (s203), When a certain period of time has elapsed from the display of the character “” (Yes in s204), the character “DiskIn” is deleted again (s205).

  The control unit 101 gives the OSD processing unit 104 a control signal for displaying the character “DiskIn” again when the re-display condition is satisfied (Yes in s202) (s203, FIG. 3 ( See 6)).

  As described above, when the re-display condition is satisfied, that is, when a channel switching operation or the like is performed or when a commercial is entered, the character “DiskIn” is displayed at an appropriate timing. Can be made.

  In addition, in the optical disc system 1, except for s103 determination affirmation and s104 determination affirmation, once the character “DiskIn” is displayed on the screen all the time, it may be annoying to the user. is there. However, in the optical disc system 201, even if the same determinations s206 determination affirmation and s207 determination affirmation are excluded, the character “DiskIn” is displayed every time the channel switching operation of the TV 201 is performed, and “DiskIn” Each time a certain time elapses from the display of the characters, the characters “DiskIn” are deleted. Therefore, the characters “DiskIn” can be appropriately displayed on the screen.

  As described above, the characters “DiskIn” can be appropriately displayed on the screen at an appropriate timing. Therefore, the user does not feel bothered.

  On the other hand, when determining that the DiskIn display cancellation signal is received, the control unit 101 returns to s201 and continues the processing. When the control unit 101 receives the DiskIn display cancellation signal, the optical disc 20 is not set. In the unset state, the problem of duplicate setting does not occur. Therefore, the character “DiskIn” is displayed until the DiskIn display signal is received again from the control unit 11 of the optical disc apparatus 10 in s201, that is, until the optical disc 20 is set again. , Not displayed on the CRT 106A.

  If it is determined in s202 that channel switching of the TV 201, adjustment of the volume of the TV 201, and the like are not input, the control unit 101 determines whether the user has performed a power-off operation of the TV 201 with the operation unit 109 or the remote controller 121. (S208). If the TV 201 is not turned off, the control unit 101 returns to s202 and continues the processing.

  In s202 and s208, the control unit 101 is in an input waiting state waiting for the user to perform a channel switching operation, a volume adjustment operation, a power-off operation, or the like using the operation unit 109 or the remote controller 121.

  If the power-off operation of the TV 201 is performed, the control unit 101 displays a control signal indicating that the characters “DiskIn” are largely displayed on the screen of the display unit 106 before the TV 201 is powered off. (S209, see FIG. 3 (6)). Then, the OSD processing unit 104 superimposes a large “DiskIn” character on the video signal. The video processing unit 105 displays the characters “DiskIn” large on the display unit 106. As a result, the characters “DiskIn” are displayed large on the CRT 106A (see FIG. 8).

  Then, the control unit 101 turns off the TV 201 (s210) and ends this process.

  As described above, before the TV 201 is turned off, the characters “DiskIn” are conspicuous by displaying the characters “DiskIn” large on the screen of the display unit 106. Therefore, the user can see the set state of the optical disk at a glance.
