The television according to the present invention includes display means for displaying video, audio output means for outputting audio, and main body side control means for controlling at least the display means and the audio output means, as in the general case.

  When a recording disk reproducing device is mounted on a television, a completed recording disk reproducing device is incorporated in a form of being transplanted due to cost and system design difficulties. In this case, each part of the television is controlled by a control means (main body side control means) such as a microcomputer (microcomputer) of the television itself, and the recording disk playback device has its own microcomputer that exchanges signals with the microcomputer on the television side. Each part included in the reproduction apparatus side control means is controlled. This eliminates the difficulty in system design, such as controlling the playback process on the recording disk playback device side with the microcomputer on the television side. Here, regardless of the master-slave between the microcomputer on the TV side and the microcomputer on the playback device, if it is determined in advance, it is only necessary to receive user operations and execute processing while communicating with each other and grasping each other. It is.

  Hereinafter, a recording / reproducing apparatus includes a mixed recording / reproducing apparatus of a DVD / CD drive and a hard disk drive (HDD), and a liquid crystal television is exemplified as a television. For example, a PDP, an organic EL (electroluminescence) display, etc. In the case where is applied or other combinations are not particularly written, the same applies. In this example, the recording / playback apparatus has playback means for playing back and outputting the content recorded on the recording disk in the display means and audio output means of the liquid crystal television main body, and as the playback means, DVD, CD, Respective means for reproducing and outputting the content recorded in the HDD are provided.

  FIG. 1 is a block diagram showing a circuit configuration example of a television receiving system according to an embodiment of the present invention. In the figure, 1 is a television with a recording disk playback device as an example of a television, and 15 is a built-in recording disk playback device. The system microcomputer 5 of the television 1 is a recording disk playback device, and 6 is a microcomputer for the recording disk playback device 5.

  A television 1 with a built-in recording disk reproducing device includes a television broadcast receiving antenna 3, a broadcast receiving circuit 4, an input source switching circuit 7, a video signal processing circuit 8, a display timing controller 9, a liquid crystal display panel 10, a backlight control circuit 11, and a backlight. 12, an audio signal processing circuit 13, a built-in speaker 14, a radio transmission / reception circuit 16 in the television, and a main body operation unit 17. Basically, a remote controller 2 for a user to operate the television is attached, which includes a remote control display means 18, a remote control wireless transmission / reception circuit 20, a remote control storage means 21, and a remote control microcomputer 19 for controlling them. Prepare.

  The television broadcast receiving antenna 3 receives a television broadcast signal, and the broadcast receiving circuit 4 outputs a video signal and an audio signal based on the received television broadcast signal. The broadcast receiving circuit 4 is a tuner that tunes to a receiving channel, an IF circuit that lowers a received signal to an IF (Intermediate Frequency) signal frequency for demodulation, a video signal demodulating circuit that demodulates a video signal, and an audio signal. It is composed of an audio signal demodulating circuit for demodulating.

  The input source switching circuit 7 is a video signal processing circuit that receives a video / audio signal input from the broadcast receiving circuit 4, the recording disk reproducing device 5, or an external video signal input terminal and an external audio signal input terminal (not shown). 8 and the output to the audio signal processing circuit 13 are switched. This switching is executed by the control from the system microcomputer 15 based on the control signal from the in-TV wireless transmission / reception circuit 16 received from the remote controller 2 operated by the user and the control signal from the TV main body operation unit 17.

  The video signal processing circuit 8 performs various types of video processing on the video signal input from the input source switching circuit 7 under the control of the system microcomputer 15, and passes the processed signal to the display timing controller 9. The display timing controller 9 performs display control on the liquid crystal display panel 10 under the control of the system microcomputer 15. The liquid crystal display panel 10 displays an image based on the display control.

  On the other hand, the backlight control circuit 11 controls lighting of the backlight 12. The light emitted from the backlight 12 irradiates the liquid crystal display panel 10 from the back side, so that the user can visually recognize the image. Here, the liquid crystal display panel 10, the display timing controller 9, the video signal processing circuit 8, the backlight 12, and the backlight control circuit 11 correspond to the display means described above.

  The audio signal processing circuit 13 performs various types of audio processing on the audio signal input from the input source switching circuit 7 under the control of the volume control signal from the system microcomputer 15, and passes the processed signal to the built-in speaker 14. . Here, the audio signal processing circuit 13 and the built-in speaker 14 correspond to the above-described audio output means.

  The main body operation unit 17 is a part composed of keys and buttons for receiving various user operations such as channel switching, input switching, mode switching, volume adjustment, backlight brightness adjustment, and other settings. Good. An operation signal input from the main body operation unit 17 is transmitted to the system microcomputer 15. The radio transmission / reception circuit 16 in the television receives a signal of the same user operation by the remote controller 2 and transmits it to the system microcomputer 15. Here, the body operation unit 17 and the remote controller 2 correspond to the user operation input means.

  The recording disk playback device 5 is provided with disk determination means for determining whether or not the content stored on the recording disk to be played back contains video. Therefore, the above-mentioned playback apparatus side control means also controls the disk discrimination means. Here, the playback device side control means is exemplified by the recording disk playback device microcomputer 6, and a program for executing the final determination of the disk determination device is stored in an executable manner in the ROM of the recording disk playback device microcomputer 6. As an example.

  The disc discriminating unit preferably discriminates the presence or absence of video for the stored content by discriminating the type of recording disc to be reproduced. For example, based on TOC (Table Of Contents) information read from a recording disk such as an audio CD or DVD, the type of the media loaded in the recording disk playback device 5 is determined.

  When the disc discriminating unit discriminates the recording disc storing only the content that does not contain video, the main body side control unit controls the display unit to reduce power consumption. It shall have a drive control means. The result of the discriminating by the disc discriminating means may be transmitted as a signal from the reproducing apparatus side control means to the main body side control means. In other words, the recording disk reproducing device microcomputer 6 may transmit the determination result signal to the system microcomputer 15.

  Here, driving to reduce power consumption refers to driving to reduce power consumption so as to reduce or eliminate power consumption. In the case of the liquid crystal display device in this example, the system microcomputer 15 performs backlight control. The circuit 11 is controlled to reduce or eliminate the brightness of the backlight 12. Even in a configuration that does not employ a liquid crystal display device, any control that leads to some power saving may be used. Hereinafter, an example in which power consumption is reduced or eliminated by the control of the backlight control circuit 11 will be described.

  In general, a video signal is included in a DVD and a video signal is not included in a CD. Therefore, when playing a CD, the power consumption is reduced by the drive control means, and when playing a DVD, the power consumption is reduced. The control may be performed as it is. For example, if the audio disc is detected by the disc discrimination means, the power saving control of the backlight control circuit 11 may be performed.

  The drive control means described above controls the display means to reduce power consumption when the disc discriminating means results in the recording disc storing only the content not containing the video as the reproduction target. However, for example, for a CD that contains video, for example, the power consumption may be reduced by the drive control means only when the video is not reproduced. As described above, when the disc discriminating unit determines that the recording disc storing at least one content that does not include video is the target of playback and the content that does not include video is being played back, What is necessary is just to make it control so that power consumption may be reduced with respect to a means.

  Moreover, it is preferable that the above-described drive control unit includes a drive control setting unit that allows the user to set in advance whether or not to execute control to reduce power consumption on the display unit. This user setting may be executed by inputting an operation signal to the system microcomputer 15 from the main body operation unit 17 or the remote controller 2.

  For example, the display control unit may be controlled so that the drive control setting unit displays the menu mode, and the user can set in advance based on the display unit. Further, in the drive control setting means, for example, in the case of an audio main source such as a DVD audio or a CD, it is preferable that user setting such as executing control for power saving as described above in the drive control means is also possible. . As DVD audio, still images, video clips, live scenes, interview videos, etc. that can be enjoyed with high-quality audio can also be recorded. In addition, DVD audio sound can usually be played back only by a dedicated playback device, but what is called “video compatible music” may be recorded so that it can be played back by a normal player. As described above, since video is present in the DVD audio, the power-saving control is executed even in such a case by enabling the user setting as described above.

  In the recording disk built-in television 1 in which the recording disk playback function and the television reception function are combined, the combination of the recording disk to be played back is a DVD playback with a video signal or a medium with only an audio signal without a video signal. It is easy for the system microcomputer 15 to grasp the information of the recording disk reproducing device 5 such as whether or not it is reproduced via the recording disk reproducing device microcomputer 6, and it is determined whether or not the video should be displayed on the display screen of the liquid crystal display panel 10. It becomes easy to do. Similarly, information related to contents stored on the recording disk can be easily acquired by the system microcomputer.

  When a user operation is input by the user operation input means, the drive control means is provided with means for stopping and returning to the display means so as to reduce power consumption. 12 brightness control is restored, and video display or OSD display on the liquid crystal display panel 10 is performed. However, in the conventional example, even when it is desired to display the playback state of the recording disk being played back by the recording disk playback device 5 and information related to the stored content during the power saving drive, the return means performs normal driving. It will return and it will not become a power-saving drive.

  Therefore, in the embodiment of the present invention, the in-television wireless transmission / reception circuit 16 sends information related to the reproduction state of the recording disk being reproduced and the stored content from the microcomputer 6 for the recording disk reproduction apparatus to the system microcomputer 15. The information is transferred to the wireless transmitter / receiver circuit 20 in the remote controller, and the information is displayed on the remote controller display means 18 via the remote controller microcomputer 19. By doing so, even when the user wants to confirm the playback state of the recording disk being played back and information related to the stored content, it is possible to keep the power saving drive.

  In addition, information related to the stored content is stored in the remote control storage unit 21 via the remote control microcomputer 19, and the user can record the recording disk playback device even when the TV 1 with the recording disk playback device is turned off. You can easily check the contents of the recording disk you put in, turn on the TV, display the contents of the recording disk on the monitor, and remove the recording disk to consume wasted power This makes it possible to prevent the user from confirming the contents of such annoying recording disk.

  As described above, the power consumption can be further reduced as compared with the prior art, and as a result, the life of the lamp of the backlight 12 can be improved, so that energy saving, long life, and usability can be improved.

  Of course, when there is a video menu operation event due to switching of the input source or input of a user operation signal from the main body operation unit 17 or the remote controller 2, the stage where the display of the television 1 with a built-in recording disk playback device has become necessary. Thus, there is also provided means for automatically controlling the brightness of the backlight 12 to return to normal.

  Also, in the conventional example, for example, even if the user has set the backlight control to be turned off when the user is an audio source with the above-described drive control setting means, the person who set it forgets that fact for a long time. In order not to be mistaken for the failure of the television 1 with a built-in recording disk playback device, the TV 1 with a built-in recording disk playback device controls the display means to reduce power consumption with the drive control means described above. In addition, a light emitting means such as an LED that emits light at a blinking cycle different from that at the time of failure is provided, and the user can visually recognize that the backlight 12 is in the extinguishing mode by displaying the LED. Then, since the state of the television 1 with a built-in recording disk playback device can be notified to the remote controller 2 by radio, the light-off mode as in the conventional example is not possible. It may be provided with means for visually recognize the user on the remote controller 2.

  FIG. 2 is a flowchart for explaining an example of a recording disk reproduction process in the television receiving system of FIG. The television 1 with a built-in recording disk playback device performs the recording disk playback processing in the following procedure, for example, with the above-described configuration.

  First, whether the system microcomputer 15 displays a television program received by the broadcast receiving circuit 4 is determined based on a user operation or a switching instruction signal to the input source switching circuit 7 issued based on a default setting value ( Step S1) When a television program is being displayed, control is performed to display the received video on the liquid crystal display panel 10 (step S2). At this time, naturally, the backlight 12 is normally lit.

  In the case of NO at step S1, a switching instruction signal to the input source switching circuit 7 issued based on a user operation (including a recording disk insertion operation) or the like as to whether or not to perform media playback by the recording disk playback device 5 (Step S3). When reproducing the media of the recording disk, the recording disk reproducing device microcomputer 6 first determines the medium by the recording disk determining means (step S4), and determines the presence or absence of video (step S5). The result of step S5 is notified to the system microcomputer 15. If there is video, the playback video is output to the liquid crystal display panel 10 (step S6).

  On the other hand, when there is no video, and when media playback is not performed in step S3 (that is, when nothing is executed), the system microcomputer 15 controls the backlight control circuit 11 so that the backlight 12 is turned off (step S7). ). Subsequently, the system microcomputer 15 receives information related to the content stored in the recording disk playback apparatus microcomputer 6 and information such as the playback state, and transmits the information to the in-television wireless transmission / reception circuit 16 (step S8). . The in-remote radio transmitter / receiver circuit 20 receives the information and displays information on the in-remote control display means 18 and writes information in the in-remote storage means 21 via the remote control microcomputer 19 (step S9).

  Subsequently, the system microcomputer 15 determines whether or not the music has been selected based on reproduction information from the recording disk reproduction apparatus microcomputer 6 and user operation information based on a signal from the main body operation unit 17 or the radio transmission / reception circuit 16 in the television. (Step S10). If it is determined in step S10 that the music has been selected, the process returns to step S5. Further, the system microcomputer 15 determines whether or not the input has been switched based on user operation information based on a signal from the main body operation unit 17 or the radio transmission / reception circuit 16 in the television (step S11). If it is determined in step S11 that the input has been switched, the process returns to step S1.

  Further, the system microcomputer 15 determines whether or not a video menu operation event has occurred based on user operation information based on a signal from the main body operation unit 17 or the radio transmission / reception circuit 16 in the television (step S12). When a video menu operation event occurs, the backlight control circuit 11 is controlled so that the backlight 12 is turned on (returned), and control for performing OSD display related to the user operation is executed (step S13). Steps S10, S11, and S12 are repeated until the event occurs.
