Abstract

Disclosed are a digital TV and a method for controlling same. The method for controlling a digital TV according to one embodiment of the present invention includes: displaying a user interface (UI) capable of selecting the standby mode for a power-off operation; and disconnecting the power source for a display panel so as to enter the standby mode when the standby mode is set through the UI in the power-off operation, and a power-off command is received. The standby mode includes a lower standby mode based on the operation of the digital TV and a network function, and the digital TV in the standby mode stops AV channel communication and performs SI channel communication.

Claims

1. A method of processing a standby mode at a digital television, the method comprising:

displaying User Interface (UI) for selecting the standby mode for an operation of power off of the digital television; and

entering the standby mode and cutting a power supply to a display panel of the digital television when the standby mode is set up during the operation of the power off by the UI and when command for the power off of the digital television is received;

wherein the standby modes includes sub standby modes related to a network function of the digital television and an operation of the digital television, and

wherein the digital television of the standby mode is configured to stop processing data of an Audio/Video (AV) channel and perform processing data of Service Information (SI) channel.

2. The method of claim 1,

wherein the sub standby modes include at least one of a network standby mode where the digital television is operated as a network Access Point (AP), a Bluetooth standby mode where the digital television is operated by receiving a Bluetooth input, a record mode for recording a broadcasting service, and a home server mode where the digital television is operated as a home network server.

3. The method of claim 1,

wherein the digital television of the standby mode receives at least one of software download information, application upgrade information, network device controlling information, and SI via the SI channel.

4. The method of claim 3,

wherein the SI includes at least one of channel list information, program guide information, Video on Demand (VOD) list information, and widget information.

5. The method of claim 1,

wherein the digital television of the standby mode receives control information for controlling external devices connected to a home network via the SI channel.

6. The method of claim 5,

wherein the control information includes power information for controlling power of the external devices connected to the home network.

7. A digital television for processing a standby mode, the digital television comprising:

a video output processor configured to process video data;

a display panel configured to display the processed video data;

a network interface configured to perform a network communication;

an external input receiver configured to receive an external input signal; and

a main processor configured to control the video output processor to process User Interface (UI) for selecting a standby mode for an operation of power off of the digital television; and

wherein the main processor is further configured to control cutting a power supply to the display panel when the standby mode is set up during the operation of the power off by the UI and when command for the power off of the digital television is received,

wherein the main processor is further configured to control entering the standby mode by stopping processing data of an Audio/Video (AV) channel and performing processing data of Service Information (SI) channel, and

wherein the standby modes includes sub standby modes related to a network function of the digital television and an operation of the digital television.

8. The digital television of claim 7,

wherein the sub standby modes include at least one of a network standby mode where the digital television is operated as a network Access Point (AP), a Bluetooth standby mode where the digital television is operated by receiving a Bluetooth input, a record mode for recording a broadcasting service, and a home server mode where the digital television is operated as a home network server.

9. The digital television of claim 7,

wherein the digital television of the standby mode receives at least one of software download information, application upgrade information, network device controlling information, and SI via the SI channel.

10. The digital television of claim 9,

wherein the SI includes at least one of channel list information, program guide information, Video on Demand (VOD) list information, and widget information.

11. The digital television of claim 7,

wherein the digital television of the standby mode receives control information for controlling external devices connected to a home network via the SI channel.

12. The digital television of claim 11,

wherein the control information includes power information for controlling power of the external devices connected to the home network.
