Display apparatus and control method thereof
First Claim
1. A display apparatus comprising:
- a display part to display an image thereon;
a video signal processor to convert a first input video signal into a signal having a format displayable by the display part and a second input video signal different from the first input video signal into a signal having a format displayable by the display part;
a network controller connectable to a network to transmit and/or receive data according to a predetermined protocol;
a data processor to process the data transmitted and/or received through the network controller into the second video signal having a format processible by the video signal processor; and
a controller in communication with the video signal processor, the network controller, and the data processor to control display of the first and second video signals and to control power to be supplied to the data processor according to a determination of whether data is transmitted and/or received by the network controller through the network,wherein the network controller supplies data receiving information regarding whether the data is transmitted and/or received through the network to the controller, and the controller maintains power to the video signal processor and the network controller while shutting off power to the data processor when the data receiving information indicates that no data is transmitted and/or received through the network controller.

Abstract
A display apparatus includes a display part to display an image thereon, a video signal processor to convert an input video signal into a signal having a format displayable by the display part, a network controller connectable to a network to transmit and receive data according to a predetermined protocol, a data processor to process the data transmitted and/or received through the network controller into a video signal processible by the video signal processor, and a controller to control power to be supplied to the data processor according to whether the data is being transmitted and/or received by the network controller through the network. Accordingly, the display apparatus transmits and receives data through a network and reduces power consumption.

7. A display apparatus, comprising:
-
a network controller connectable to a network to receive network image data through the network; a data processor to process the network image data and to generate a network video signal based on the network image data; a video signal processor that processes a first image data received from a first source and the network video signal received from the data processor to be displayed; a sensing unit to sense whether the network controller is in a receiving state or an idle state; and a controller in electrical communication with the data processor, the video signal processor, and the sensing unit to control an amount of power supplied to the data processor based on the sensed state of the network controller and to maintain power to the video signal processor and the network controller such that the display apparatus displays the first image data being different from the network image data while the controller cuts off power to the data processor when the network controller is in the idle state. - View Dependent Claims (8, 9, 10, 11, 12)

13. A display apparatus connectable to a network to receive first image data through the network and to display the received first image data thereon, comprising:
-
a network controller to receive the first image data; a processing unit connected to the network controller to process the first image data received through the network to make the image data displayable and to generate a network video signal to be displayed via the display apparatus; and a controller to determine whether the first image data is being received through the network and to cut off power supplied to the processing unit when the first image data is not received through the network for a predetermined amount of time while controlling the display apparatus to display second image data corresponding to an input video signal different from the network video signal, the controller maintaining power to the network controller and a video signal processor when the power to the processing unit is cut off, wherein the video signal processor converts the network video signal into a format displayable by the display apparatus and converts the video input signal into a format displayable by the display apparatus. - View Dependent Claims (14, 15, 16)
