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.

Claims

1. A display apparatus comprising:

a display part to display an image thereon;

a video signal processor to convert an input video signal into a signal having 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 a video signal having a format processible by the video signal processor; and

a controller 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.

2. The display apparatus according to claim 1, 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 controls the power supplied to the data processor based on the data receiving information supplied by the network controller.

3. The display apparatus according to claim 1, wherein the data processor comprises:

a data storage part to store at least one control routine therein to process data received through the network controller;

a memory to load the control routine;

a main processor to load the control routine to the memory and to execute the control routine; and

a bridge circuit to allow the data storage part and the main processor to communicate with each other.

4. The display apparatus according to claim 3, wherein the main processor converts the data received through the network controller into a video signal and outputs the video signal, and the data processor further comprises a video signal transmitter to convert the video signal output by the main processor into a the video signal having the format processible by the video signal processor and to supply the converted video signal to the video signal processor.

5. The display apparatus according to claim 1, wherein the controller cuts off the power supplied to the data processor when data is not received by the network controller through the network for a predetermined period of time.

6. The display apparatus according to claim 5, wherein the controller controls the power to be supplied to the data processor when the data is received by the network controller through the network when the power supplied to the data processor is in a state of being cut off from the data processor.

7. A display apparatus, comprising:

a network controller connectable to a network to receive image data through the network;

a data processor to process the image data; and

a sensing unit to sense whether the network controller is in a receiving state or an idle state, and to control an amount of power supplied to the data processor based on the sensed state of the network controller.

8. The display apparatus according to claim 7, wherein the sensing unit senses that the network controller is in the idle state when the network controller does not receive the image data through the network for a predetermined period of time, and senses that the network controller is in the receiving state whenever the network controller is not in the idle state.

9. The display apparatus according to claim 7, wherein the sensing unit senses that the network controller is in the receiving state when the network controller is receiving the image data through the network, and senses that the network controller is in the idle state when the network controller is not receiving the image data through the network.

10. The display apparatus according to claim 7, wherein the sensing unit controls power to be supplied to the data processor only when the network controller is sensed to be in the receiving state.

11. The display apparatus according to claim 7, wherein the sensing unit decreases the amount of power supplied to the data processor when the network controller is sensed to be in the idle state.

12. The display apparatus according to claim 7, further comprising:

an input unit to input an image signal;

a display unit to display at least one of the image signal and the image data; and

a video signal processor to convert the input image signal and the processed image data into a format displayable by the display unit.

13. A display apparatus connectable to a network to receive image data through the network and to display the received image data thereon, comprising:

a processing unit to process the image data received through the network to make the image data displayable; and

a controller to determine whether the image data is being received through the network and to cut off power supplied to the processing unit when the image data is not received through the network for a predetermined amount of time.

14. The display apparatus according to claim 13, wherein the controller controls the power to be supplied to the processing unit when the image data is received through the network after not being received for the predetermined amount of time.

15. The display apparatus according to claim 13, further comprising:

a video input unit to input a video signal; and

a display unit to display the video signal and the image data.

16. The display apparatus according to claim 15, wherein the processing unit comprises:

a data processing unit to process the image data received through the network into an image signal; and

a signal processing unit to convert the video signal and the image signal into a format displayable by the display.

17. A method of controlling a display apparatus having a display part to display an image thereon, a video signal processor to convert an input video signal into a format displayable by the display part, a network controller connectable to a network and to transmit and receive data according to a predetermined protocol, and a data processor to process the data transmitted and/or received through the network controller, the method comprising:

determining whether data is being received by the network controller through the network;

cutting off power supplied to the data processor if it is determined that the data is not being received by the network controller; and

supplying power to the data processor if it is determined that data is being received by the network controller.

18. A method of controlling a display apparatus having a network controller to receive image data through a network and data processor to processor the image data received through the network, the method comprising:

sensing whether the network controller is in a receiving state or an idle state; and

controlling an amount of power supplied to the data processor based on the sensed state of the network controller.

19. A computer readable recording medium having executable codes to perform a method of controlling a display apparatus having a display part to display an image thereon, a video signal processor to convert an input video signal into a format displayable by the display part, a network controller to be connected to a network and to transmit and receive data according to a predetermined protocol, and a data processor to process data transmitted and/or received through the network controller, the method comprising:
