Abstract

A display apparatus which is controlled by a remote control apparatus is provided. The display apparatus includes an output unit including a display and a speaker, a communicator configured to perform communication with the remote control apparatus while the display apparatus is turned off, and a processor configured to be turned on according to a predetermined signal received from the remote control apparatus while the display apparatus is turned off, and control an operation of the output unit based on at least one of channel selection information and volume control information included in the predetermined signal.

First claim

What is claimed is:

1 . A display apparatus which is controllable by a remote control apparatus, the display apparatus comprising:
an output unit including a display and a speaker; a communicator configured to receive a signal from the remote control apparatus while the display apparatus is turned off; and at least one processor configured to, after the display apparatus is turned on from being turned off, control at least one of the display and the speaker of the output unit based on at least one of channel selection information and volume control information included in the signal received from the remote control apparatus while the display apparatus is turned off.

2 . The display apparatus as claimed in claim 1 , wherein the signal is a Radio Frequency (RF) signal.

3 . The display apparatus as claimed in claim 1 , wherein
the communicator is configured to receive a wake signal from the remote control apparatus while the display apparatus is turned off, and the at least one processor is configured to
activate the display apparatus excluding the output unit, in response to the received wake signal and,
in response to the received signal that includes the at least one of channel selection information and volume control information, activate the output unit, to thereby turn on the display apparatus, and thereafter perform the control of the at least one of the display and the speaker of the output unit.

4 . The display apparatus as claimed in claim 1 , wherein the at least one processor, in response to receiving a signal for turning off the display apparatus, controls to transmit, to the remote control apparatus, at least one of channel information and volume information of a content which is output through the output unit at a time when the signal for turning off the display apparatus is received.

5 . The display apparatus as claimed in claim 1 , wherein the signal further includes information regarding at least one of an external input mode and an application program selected by the remote control apparatus.

6 . A method of controlling a display apparatus, comprising:
receiving, by a communicator included in the display apparatus and which is configured to perform communication with a remote control apparatus while the display apparatus is turned off, a signal from the remote control apparatus while the display apparatus is turned off; and after the display apparatus is turned on from being turned off, controlling, by at least one processor included in the display apparatus, at least one of a display and a speaker included in an output unit of the display apparatus, based on at least one of channel selection information and volume control information included in the signal received from the remote control apparatus while the display apparatus is turned off.

7 . The method as claimed in claim 6 , wherein the signal is a Radio Frequency (RF) signal.

8 . The method as claimed in claim 6 , further comprising, prior to the controlling:
activating, by the at least one processor, the display apparatus excluding the output unit according to a wake signal received from the remote control apparatus by the communicator while the display apparatus is turned off, and in response to receiving the signal including the at least one of channel selection information and volume control information, activating the output unit by the at least one processor, to thereby turn on the display apparatus.

9 . The method as claimed in claim 6 , further comprising:
in response to receiving a signal by the display apparatus for turning off the display apparatus, transmitting, to the remote control apparatus by the communicator, at least one of channel information and volume information of a content which is output through the output unit at a time when the signal for turning off the display apparatus is received.

10 . The method as claimed in claim 6 , wherein the signal further includes information regarding at least one of an external input mode and an application program selected by the remote control apparatus.

11 . A remote control apparatus comprising:
a user interface configured to receive a user command; a communicator configured to perform communication with a display apparatus while the display apparatus is turned off; a display configured to display a User Interface (UI) screen to provide information regarding a content received by the remote control apparatus from an external server in real time; and at least one processor configured to transmit, to the display apparatus via the communicator while the display apparatus is turned off, a signal which includes at least one of channel selection information and volume control information according to a user command input via the UI screen, wherein the transmitted signal causes the display apparatus to turn on from being turned off and to thereafter control at least one of a display and a speaker of the display apparatus based on at least one of the channel selection information and the volume control information included in the transmitted signal.

12 . The remote control apparatus as claimed in claim 11 , wherein the signal is a Radio Frequency (RF) signal.

13 . The remote control apparatus as claimed in claim 11 , wherein
the at least one processor, in response to a predetermined event occurring, causes the remote control apparatus to transmit a wake signal to the display apparatus to thereby activate the display apparatus excluding an output unit of the display apparatus that includes the display and the speaker, and the signal which includes the at least one of channel selection information and volume control information causes the output unit to be activated, to thereby cause the display apparatus to turn on.

14 . The remote control apparatus as claimed in claim 11 , further comprising:
a storage configured to store channel and volume information which is received from the display apparatus as the display apparatus is turned off, wherein the at least one processor controls to display the UI screen based on the channel and volume information stored in the storage.

15 . The remote control apparatus as claimed in claim 11 , wherein the signal transmitted to the display apparatus includes at least one of external input mode selection information and application program selection information according to the user command.

16 . A controlling method of a remote control apparatus, comprising:
displaying, on the remote control apparatus, a UI screen to provide information regarding a content received from an external server in real time; and transmitting, to a display apparatus which is capable of communicating with the remote control apparatus while the display apparatus is turned off, a signal while the display apparatus is turned off and which includes at least one of channel selection information and volume control information according to a user command input via the UI screen, wherein the transmitted signal causes the display apparatus to turn on from being turned off and to thereafter control at least one of a display and a speaker of the display apparatus based on the at least one of the channel selection information and the volume control information included in the transmitted signal.

17 . The method as claimed in claim 16 , wherein the signal is a Radio Frequency (RF) signal.

18 . The method as claimed in claim 16 , further comprising:
transmitting, by the remote control apparatus in response to a predetermined event occurring, a wake signal to the display appara
