Abstract

A display apparatus and a searching method are provided. The display apparatus includes: a receiver configured to receive a broadcasting signal; a display configured to display content of the received broadcasting signal; a communicator configured to transmit a first keyword and a content title and receive a first search result performed based on the first keyword and the content title; and a controller configured to extract a plurality of keyword candidates from the search result, display the plurality of keyword candidates on the display, if a second keyword is selected as one of the plurality of keyword candidates either manually or in response to a detected event, to transmit the second keyword through the communicator in order to perform a search for the second keyword.

Claims

1. A display apparatus comprising:

a receiver configured to receive a broadcasting signal;

a display configured to display content of the received broadcasting signal;

a communicator configured to transmit a first keyword and a content title and to receive a first search result based on the first keyword and the content title; and

a controller configured to extract a plurality of keyword candidates from the first search result, display the plurality of keyword candidates on the display, and if a second keyword is selected as one of the plurality of keyword candidates, to transmit the second keyword through the communicator to perform a search for the second keyword.

2. The display apparatus of claim 1, wherein the controller controls the communicator to automatically extract the first keyword and the content title based on program guide information of the broadcasting signal and to transmit the extracted first keyword and content title.

3. The display apparatus of claim 1, wherein the controller controls the communicator to display a user interface (UI) screen for receiving the first keyword and the content title through the display and, if the first keyword and the content title are received through the UI screen, to transmit the first keyword and the content title.

4. The display apparatus of claim 1, wherein if a second search result of the second keyword is received, the controller displays a screen comprising the second search result and the content on the display,

wherein the screen comprises a first area configured to display the content, a second area configured to display the plurality of keyword candidates, a third area configured to display the second keyword selected from the plurality of keyword candidates, a fourth area configured to display information about a search server, and a fifth area configured to display a result of a second search.

5. The display apparatus of claim 4, wherein the controller arranges and displays the plurality of keyword candidates in the second area according to a frequency of the plurality of keyword candidates in the first search result.

6. The display apparatus of claim 4, wherein the controller arranges and displays the plurality of keyword candidates in the second area according to a frequency of the plurality of keyword candidates for which search requests are made.

7. The display apparatus of claim 1, wherein the first search result is received from a search server, the search server being a Social Networking Service (SNS) server,

wherein the controller receives a second search result corresponding to the second keyword among SNS information registered in the SNS server and displays the second search result through the display.

8. A search method of a display apparatus, the searching method comprising:

receiving a broadcasting signal;

transmitting a first keyword and a content title of the received broadcasting signal;

if a first search result generated based on the transmitted first keyword and content title is received, extracting a plurality of keyword candidates from the first search result;

displaying the plurality of keyword candidates; and

if a second keyword is selected as one of the plurality of keyword candidates, transmitting the second keyword in order to perform a search for the second keyword.

9. The searching method of claim 8, wherein the transmitting of the first keyword and the content title comprises:

automatically extracting the first keyword and the content title based on program guide information of the broadcasting signal; and

transmitting the extracted first keyword and content title.

10. The searching method of claim 8, wherein the transmitting of the first keyword and the content title comprises:

displaying a user interface (UI) screen for receiving the first keyword and the content title; and

if the first keyword and the content title are input through the UI screen, transmitting the first keyword and the content title.

11. The searching method of claim 8, further comprising:

if a second search result of the second keyword is received, displaying a screen comprising the second search result and the content,

wherein the screen comprises a first area configured to display the content, a second area configured to display the plurality of keyword candidates, a third area configured to display the second keyword selected from the plurality of keyword candidates, a fourth area configured to display information about a search server, and a fifth area configured to display the second search result of the second keyword.

12. The searching method of claim 11, wherein the plurality of keyword candidates are arranged and displayed in the second area according to a frequency of the plurality of keyword candidates in the first search result.

13. The searching method of claim 11, wherein the plurality of keyword candidates are arranged and displayed in the second area according to a frequency of the plurality of keyword candidates for which search requests are made.

14. The searching method of claim 8, wherein the first search result is received from a search server, the search server being a Social Networking Service (SNS) server,

wherein the searching method further comprises:

receiving and displaying a second search result corresponding to the second keyword among SNS information registered in the SNS server.

15. A display apparatus comprising:

a receiver configured to receive a broadcasting signal;

a display configured to display content of the received broadcasting signal;

a communicator configured to transmit a first keyword and a content title and to receive a first search result based on the first keyword and the content title; and

a controller configured to extract a plurality of keyword candidates from the first search result and display the plurality of keyword candidates on the display, to recognize an event and extract a keyword from the plurality of keyword candidates based on the recognized event, to select the extracted keyword as a second keyword, and to transmit the second keyword in order to perform a search for the second keyword.

16. The display apparatus of claim 15, wherein the controller is further configured to detect a finger gesture of a user as an event used to indicate the second keyword.

17. The display apparatus of claim 15, wherein the controller is further configured to detect a palm gesture of a user as an event used to indicate a grab and throw operation.

18. The display apparatus of claim 15, wherein the controller is further configured to detect audio of a user as an event used to indicate the second keyword.

19. A search method of a display apparatus, the search method comprising:

receiving a broadcasting signal;

transmitting a first keyword and a content title of the received broadcasting signal;

if a first search result generated based on the transmitted first keyword and content title is received, extracting a plurality of keyword candidates from the first search result;

displaying the plurality of keyword candidates;

recognizing an event corresponding to a selection of a second keyword from among the plurality of keyword candidates; and
