Abstract
A method of controlling a power supply of a digital TV with a function of executing applications is provided. According to the method, in a digital TV apparatus with the application executing function, a power supply of a general-purpose CPU platform which processes data required for executing an application and a power supply of a decoding unit which decodes digital broadcasting data and outputs the decoded data on a screen are controlled separately.
Claims26
A digital TV apparatus having an application-execution function, the apparatus comprising:
- a general-purpose central processing unit (CPU) platform which processes data required for executing an application;
- a decoding unit which operates independently of the general-purpose CPU platform, decodes digital broadcasting data, and outputs the decoded data on a screen;
- and
- a remote controller signal processing unit which controls a power supply of the general-purpose CPU platform and a power supply of the decoding unit, separately, according to a received remote controller signal,
- wherein when the general-purpose CPU platform operates at a normal mode, the decoding unit outputs the decoded data on the screen through a video processor of the general-purpose CPU platform, and when the general-purpose CPU platform operates at a power-saving mode, the decoding unit outputs the decoded data on the screen through a display port.
A method of controlling a power supply of a digital TV apparatus having an application-execution function, the method comprising:
- performing system booting of a general-purpose CPU platform which executes an application when a TV power supply is turned on;
- controlling a power supply of a decoding unit which receives a digital broadcasting signal and outputs a video signal on a screen, and a power supply of the general-purpose CPU platform, separately, according to a received remote controller signal;
- and
- outputting the video signal on the screen according to the mode of the power supply of the general-purpose CPU platform, wherein when the general-purpose CPU platform operates at a normal mode, the video signal is output on the screen through a video processor of the general-purpose CPU platform, and when the general-purpose CPU platform operates at a power-saving mode, the video signal is output on the screen through a display port.
