OB has the same configuration as the television 100A with a built-in reproducing device shown in FIG. 1 except that the optical disk reproducing device Pa is replaced with the optical disk reproducing device Pb. Further, the optical disk reproducing device Pb includes a screen saver 14 provided for displaying an image indicating that the disk data reader 30 is stopped on the display 5.
The configuration is the same as that of the optical disc reproducing apparatus Pa except that a symbol "." Therefore, description of portions common to the television with a built-in playback device 100A according to the first embodiment will be omitted, and only features unique to the television with a built-in playback device 100B according to the present embodiment will be described.

The operation of the television 100B with a built-in playback device will be described below. In the present embodiment, the operation in the second viewing mode is different from that in the first embodiment. That is, when the R-TUNE key 42 is operated while the optical disk 11 is being played and viewed, the controller 8a issues a temporary holding request to the disk playback controller 12. The disk reproduction controller 12 immediately stores the current reproduction position in the reproduction position storage register 13 and stops the disk data reader 30 at the same time. The disk reproduction controller 12 further drives the screen saver 14 via the AV decoder 20 to supply the screen saver signal Ss to the AV decoder 20. The AV decoder 20 replaces the reproduction signal from the optical disc 11 with
The screen saver signal Ss is output to the AV input switch 3 as the internal AV signal Sav.

Then, when the R-TUNE key 42 is operated again to request reproduction / viewing of the optical disk 11 again, the controller 8a causes the disk reproduction controller 12 to stop the operation of the screen saver 14, and the reproduction position storage register. 1
Then, the disc data reader 30 is operated so as to read the content of No. 3 and reproduce it from that position.

(Third Embodiment) A television with a built-in playback device according to a third embodiment of the present invention will be described with reference to FIG. TV 10 with built-in playback device according to this example
0C has the same configuration as the television 100A with a built-in playback device shown in FIG. 1 except that the optical disc playback device Pa is replaced by the optical disc playback device Pc. Further, the optical disc reproducing device Pc is the same as the optical disc reproducing device Pa except that a sequence register for storing whether the data recorded on the optical disc 11 has a single sequential structure or a multi-sequential structure is added. It is configured. Therefore, description of portions common to the television with built-in playback device 100A according to the first embodiment will be omitted, and only features unique to the television with built-in playback device 100C according to the present embodiment will be described.

The television 100C with a built-in reproducing apparatus supports the reproduction of a video disk represented by a DVD as the optical disk 11. Such video discs are classified into one of a single sequential type and a multi-sequential type according to the structure of content data. Video discs whose content is a movie or the like generally have data recorded in a single sequential structure. On the other hand, video disks for special purposes such as demonstrations are recorded with data in a multi-sequential structure.

With a single-sequential type video disc, the playback position when temporarily held can be clearly grasped. However, multi-sequential type video discs generally cannot clearly grasp the playback position at the time of the temporary holding process, and when trying to resume playback from the point of holding, the playback may start from an unexpected location. Inconvenience can occur. In order to avoid such a situation, in the present embodiment, the operation in the above-described second viewing mode is changed depending on whether the optical disk 11 is of a single sequential type or a multi-sequential type.

Whether the data structure type of the optical disk 11 is single sequential or multi-sequential is determined by the disk reproduction controller 12 at the start of reproduction of the optical disk 11, and is stored in the reproduction position storage register 13. Then, when the user sets the R-TUNE
When the key 42 is operated to request temporary holding of the optical disk reproducing apparatus Pc, the controller 8a
Query the data structure type of the disc currently being played. The disc playback controller 12 reads the data structure type of the optical disc 11 from the sequence register 15 and notifies the controller 8a.

If the optical disk 11 is of a single sequential type, the controller 8a issues a temporary holding command to the disk reproduction controller 12, as in the case of the television 100A with a built-in reproducing apparatus according to the first embodiment. On the other hand, if the optical disc 11 is a multi-sequential type,
The controller 8a does not issue a temporary holding command to the disc reproduction controller 12. When the temporary holding command involves switching of the AV input switch 3, the controller 8a causes only the switching operation of the AV input switch 3 to be performed.

(Fourth Embodiment) A television with a built-in reproducing apparatus according to a fourth embodiment of the present invention will be described with reference to FIG. TV 10 with built-in playback device according to this example
0D has the same configuration as the television 100A with a built-in playback device shown in FIG. 1 except that a unit power supply 16 for supplying power to the optical disc playback device Pa is added.
The unit power supply 16 is controlled by the controller 8a,
From the main power supplied from an external main power supply (not shown), unit power necessary for driving the optical disk reproducing device Pa is generated.

The purpose of the present embodiment is to improve the power consumption of the optical disc reproducing apparatus Pa at the time of a temporary holding request. That is, the operation in the second viewing mode is different from that in the first embodiment. More specifically, when playing back and viewing the optical disc 11, R-TUN
When the E key 42 is operated, the controller 8a issues a temporary holding request to the disc reproduction controller 12. The disk reproduction controller 12 determines the current reproduction position, writes the content in the reproduction position storage register 13, and issues a stop request to the disk data reader 30. Further, after data backup, the disk reproduction controller 12 sends a completion report to the controller 8a. Controller 8
a stops the unit power supply unit 16 after detecting the content.

When the reproduction request of the optical disk reproducing device Pa is made again from the operation key input device 9, the controller 8a operates the unit power supply section 16. When the power supply from the unit power supply 16 is resumed, the disk reproduction controller 12 starts operating, and first determines the write contents of the reproduction position storage register 13. If the content is valid, the content is read and a command is issued to the disk data reader 30 to start reproduction from this position. The controller 8a immediately switches the AV input switch 3 to the optical disk reproducing device Pa side. In this manner, when the optical disk reproducing device Pa does not need to be operated and is temporarily held (standby), the power supply is cut off, thereby preventing wasteful power consumption.

Referring to FIG. 7, a modification of the television with a built-in reproducing apparatus according to the fourth embodiment of the present invention will be described. The television 100Dr with a built-in playback device according to the present example is provided with a main power supply MPS for supplying power to the entire television 100D with a built-in playback device, and a unit power supply 16D.
Is replaced by a unit power supply 16r. The unit power supply 16r includes a unit power generator UPS for generating a unit power for driving the optical disc reproducing device Pa from the main power and a main power supply switch PSW. The unit power generator UPS is connected to the main power supply MPS via the main power supply switch PSW.

This aims at further improving the reduction in power consumption when the optical disc reproducing device Pa is requested to be temporarily held in the television 100D with a built-in reproducing device.
Optical disc playback device P in second viewing mode described above
a is slightly different from that of the fourth embodiment. Specifically, in the television 100Dr with a built-in playback device, when a temporary holding request is made to the optical disc playback device Pa, the controller 8a operates the power supply switch SW to operate the unit power generator UPS (in other words, the unit power supply device). 16r) The main power supply is cut off. On the other hand, the unit power supply unit 1
Even when the power supply 6 is stopped, the supply of the main power to the unit power supply 16 is not interrupted.

That is, the unit power supply 16 and the unit power supply 16r (unit power generator UPS) are power converters that convert input temporary power, generate secondary power, and output it as unit power. . The power converter
Even if the secondary power is not output, an energy loss occurs in which the applied temporary power is released in the form of heat or the like. This energy loss is smaller than the power consumed by the entire optical disc reproducing apparatus Pa or a part thereof.
However, power consumption is unnecessary from the viewpoint of operation, which always occurs while power is supplied to the television 100D with a built-in playback device. In the present modification, such unnecessary loss related to power conversion is also prevented.

(Fifth Embodiment) Referring to FIG. 8, a television with a built-in reproducing apparatus according to a fifth embodiment of the present invention will be described. TV 10 with built-in playback device according to this example
0E is configured in the same manner as the television 100D with a built-in reproducing apparatus shown in FIG. 6 except that a timer 17 for measuring an arbitrary time T from the point in time when a switching request to the AV input changeover switch 3 is made is added. .

In this embodiment, by stopping the stop of the optical disc reproducing apparatus Pa when the optical disc reproducing apparatus Pa is temporarily held, by a predetermined time, it is possible to improve the user's feeling of use, power consumption and product life. The purpose is. Generally, from the viewpoint of power consumption, it is desirable that the power supply to the optical disk reproducing device Pa be immediately stopped at the time of the temporary holding request. However, in order to restart the optical disk reproducing device Pa once stopped, a large amount of starting power is required as compared with the operation. For this reason, the user interrupts the viewing of the optical disc reproducing device Pa, for example, after confirming the content of the television broadcast, and then again checks the optical disc reproducing device Pa.
For example, when the viewing of the optical disc is restarted, depending on the interruption time, the power consumption can be suppressed by continuing the operation of the optical disc reproducing device Pa. Further, from the viewpoint of the life of the optical disk reproducing device Pa, it is advantageous to suppress the number of restarts with a large amount of starting power. Also,
Since it takes time to restart the optical disc playback device Pa, there is a problem that the user's feeling that the user has to wait for viewing when the user interrupts the viewing of the optical disc playback device Pa and waits for the second time to view the content again.

That is, from the viewpoint of energy saving including resource saving, it is not the best to immediately stop the power supply to the optical disk reproducing device Pa at the time of the temporary holding request. Balance between three main factors: the amount of power saving due to the immediate stop of power supply to the optical disk reproducing device Pa, the amount of power consumption required to restart the optical disk reproducing device Pa, and the life of the optical disk reproducing device Pa due to continuous operation and intermittent operation. It is important to take Furthermore, the user's feeling of use as a product is also an important fourth main factor. The optimal values of these factors are appropriately determined according to the physical properties and use conditions of each device, and cannot be uniquely determined. Therefore, in the present modification, in order to provide a television with a built-in reproducing apparatus in consideration of these four main factors, a means for adjusting a power supply stop time to the optical disk reproducing apparatus Pa when a temporary holding is requested is further provided. It is.

That is, the operation in the second viewing mode is slightly different from that in the fifth embodiment. Specifically, the R-TUNE key 42 is used to operate the optical disc reproducing device P.
When an input switching request is made from a to the TV input side, the controller 8a immediately starts the operation of the timer 17. The controller 8a further instructs the AV input changeover switch 3 to switch the input, and instructs the disc reproduction controller 12 to temporarily hold. The disc playback controller 12 writes the current playback position into the playback position storage register 13 and then reads the disk data reader 30.
To stop. Thereafter, an arbitrary time T elapses (timer 17
If the input signal switching request by the operation key input unit 9 is not made before the interruption signal is detected), the controller 8a performs a stop process on the disc reproduction controller 12.

Upon receiving the completion signal from the disk reproduction controller 12, the controller 8a immediately transmits the unit power supply 1
6 is stopped. Thereafter, when the R-TUNE key 42 is operated to instruct reproduction of the optical disk reproducing device Pa,
The controller 8a starts up the unit power supply 16 and restarts the power supply to the optical disk reproducing device Pa. The disk reproduction controller 12 resumes operation, reads the reproduction storage position stored in the reproduction position storage register 13, and performs a position setting process on the disk data reader 30.
The data read from the disk data reader 30 is A
The AV data is reproduced by the V decoder 20 and presented through the AV input changeover switch 3.

With reference to FIG. 9, a modification of the television with a built-in reproducing apparatus according to the fifth embodiment of the present invention will be described.

As you did.

The present embodiment also aims at improving the power consumption of the optical disk reproducing device Pe when a temporary holding request is made. In other words, when a request to switch to the original channel number is made by operating the R-TUNE key 42, the controller 8a determines the content, and
The channel number stored in the AV input switch 3
The tuner connected to the TV input is set, and at the same time, the AV input switch 3 is switched to the TV input side.

Further, the controller 8a issues a sequential discrimination request to the disk reproduction controller 12. The disc reproduction controller 12 returns the contents of the sequence register 15 to the controller 8a. If it is multi-sequential, the controller 8a issues a stop request to the disk reproduction controller 12. Accordingly, the disc playback controller 12
Stops the disk data reader 30 and
The screen saver 14 is operated to output a screen saver signal Ss to the AV input switch 3 via the AV decoder 20.

If the contents of the sequence register 15 are single sequential, the timer 17 is started and a temporary holding request is made to the disk reproduction controller 12. The disk reproduction controller 12 writes the current reproduction position into the reproduction position storage register 13 and stops the disk data reader 30.

When a request for a reproduction process to the optical disk 11 reproducing device 11d is made to the key operation input unit 9 before the elapse of an arbitrary time T, the controller 8a immediately discriminates the request, and the disk reproduction controller Request 12 The disk reproduction controller 12 reads the reproduction position from the reproduction position storage register 13 and instructs the disk data reader 30 to set the position and start reproduction.
