Abstract

According to one embodiment, video display apparatus including, power switching module configured to switch between first power-supply module and second power-supply module, first power-supply module supplying direct-current power used to operate device from commercially available power, and second power-supply module supplying direct-current power from inside, power control module configured to cause first power-supply module to supply power capacity necessary for operation of receiving input of operation signal while second power-supply module is selected by power switching module and operated.

Claims

1. A video display apparatus comprising:

a power switching module configured to switch between a first power-supply module and a second power-supply module, the first power-supply module supplying a direct-current power used to operate the device from a commercially available power, the second power-supply module supplying the direct-current power from an inside;

a power control module configured to cause the first power-supply module to supply a power capacity necessary for an operation of receiving an input of an operation signal while the second power-supply module is selected by the power switching module and operated; and

a switching module configured to supply a power capacity necessary for the operation of receiving the input of the operation signal from the first power-supply module in the power switching module, independently of the power supply from the second power-supply module to which switching has been performed.

2. The video display apparatus of claim 1, wherein the switching module includes at least two power-supply systems, and maintains connection between the power control module and the first power-supply module using at least one of the power-supply systems.

3. The video display apparatus of claim 1, wherein the at least one of the power-supply systems of the switching module provides a power capacity necessary for the operation of receiving the input of the operation signal.

4. The video display apparatus of claim 2, wherein the least one of the power-supply systems of the switching module provides a power capacity necessary for the operation of receiving the input of the operation signal.

5. The video display apparatus of claim 3, wherein the second power-supply module includes a rechargeable battery having a power supplying capacity of a certain amount.

6. The video display device of claim 4, wherein the second power-supply module includes a rechargeable battery having a power supplying capacity of a certain amount.

7. A driving method:

a capacity necessary to receive an operation signal is driven while maintaining connection with a direct-current power supplied from outside when the direct-current power supplied from outside is switched to a direct-current power held inside.

8. The driving method of claim 7, wherein a switching element including at least two power-supply systems is used for switching from the direct-current power supplied from outside to the direct-current power held inside, and connection with the direct-current power supplied from outside is maintained using at least one of the power-supply systems.

9. A television receiving apparatus, comprising:

a receiving module configured to receive a video signal and an audio signal;

a playback module configured to play back the video signal and the audio signal received by the receiving module;

a display module configured to display a video played back by the playback module;

a control module configured to control operation of at least the receiving module, the playback module, and the display module;

an instruction input module configured to receive a control instruction to the control module;

a power control module configured to supply power to each of the modules from a commercially available power or an integral power; and

a switching module configured to maintain power supply to the instruction input module from the commercially available power when the power control module supplies power from the integral power.

10. The television receiving apparatus of claim 9, wherein the switching module includes at least two power-supply systems, and maintains power supply to the instruction input module using at least one of the power-supply systems.
