The display device includes a display, a communication interface comprising circuitry, a storage configured to store combined information on contents available from a plurality of input sources, and a processor configured to control the communication interface to receive an external input signal from the plurality of input sources, display, through the display, recommendation information on a content available through a first input source from among the plurality of input sources based on a viewing history of a user and the combined information stored in the storage, the viewing history of the user is a viewing history related to an external input signal provided through a second input source from among the plurality of input sources. ## Claims ### Claim 1 A display device comprising: a display; a communication interface comprising circuitry; a storage configured to store combined information on contents available from a plurality of input sources; and a processor configured to: control the communication interface to receive an external input signal from the plurality of input sources; display, through the display, recommendation information on a content available through a first input source from among the plurality of input sources based on a viewing history of a user with respect to an external input signal provided through a second input source from among the plurality of input sources and the combined information stored in the storage. ### Claim 2 (depends on 1) The display device of claim 1, wherein the processor is configured to provide the recommendation information based on an external input signal currently input through the first input source. ### Claim 3 (depends on 1) The display device of claim 1, wherein the processor is configured to provide content recommendation information available through the first input source from among the plurality of input sources, in response to occurrence of an event where it is not possible to receive the external input signal from the second input source. ### Claim 4 (depends on 1) The display device of claim 1, wherein the processor is configured to generate a combined viewing history wherein a viewing history with respect to each of the plurality of input sources is combined, and to provide the content recommendation information based on the combined viewing history. ### Claim 5 (depends on 4) The display device of claim 4, wherein the processor is configured to provide recommendation information on a content corresponding to an external input signal currently input from among the plurality of input sources based on the combined viewing history and the combined information stored in the storage. ### Claim 6 (depends on 4) The display device of claim 4, wherein the processor is configured to classify and to provide the content recommendation information based on at least one of: a viewing time of content, a viewing frequency of content, a viewing lasting time of content and a genre of content of the combined viewing history. ### Claim 7 (depends on 1) The display device of claim 1, wherein the processor is configured to generate the combined information based on at least one of: information included in a signal provided from the plurality of input sources, information provided from an external server and information included in an image provided through the display, and to store the combined information in the storage. ### Claim 8 (depends on 1) The display device of claim 1, wherein the processor is configured to update the combined information stored in the storage, in response to occurrence of at least one of: an event where the received external input signal is changed, an event where a content provided through the display is changed and an event occurring at a predetermined time. ### Claim 9 A content recommendation method of a display device, the method comprising: combining information on contents available from a plurality of input sources and storing the combined information based on an external input signal received from the plurality of input sources; and providing recommendation information on a content available through a first input source from among the plurality of input sources based on a viewing history of a user and the stored combined information, wherein the viewing history of the user is a viewing history related to an external input signal provided through a second input source from among the plurality of input sources. ### Claim 10 (depends on 9) The method of claim 9, wherein the providing recommendation information comprises providing the recommendation information based on an external input signal currently input through the first input source. ### Claim 11 (depends on 9) The method of claim 9, wherein the providing recommendation information comprises providing content recommendation information available through the first input source from among the plurality of input sources, in response to occurrence of an event where it is not possible to receive the external input signal from the second input source. ### Claim 12 (depends on 9) The method of claim 9 further comprising: generating a combined viewing history wherein a viewing history with respect to each of the plurality of input sources is combined; wherein the providing recommendation information comprises providing the content recommendation information based on the combined viewing history. ### Claim 13 (depends on 12) The method of claim 12, wherein the providing recommendation information comprises providing recommendation information on a content corresponding to an external input signal currently input from among the plurality of input sources based on the combined viewing history and the stored combined information. ### Claim 14 (depends on 12) The method of claim 12, wherein the providing recommendation information comprises classifying and providing the content recommendation information based on at least one of: a viewing time of content, a viewing frequency of content, a viewing lasting time of content and a genre of content of the combined viewing history. ### Claim 15 (depends on 9) The method of claim 9, wherein the combining and storing comprises generating the combined information based on at least one of: information included in a signal provided from the plurality of input sources, information provided from an external server and information included in an image provided through the display, and storing the combined information. ### Claim 16 (depends on 9) The method of claim 9 further comprising: updating the stored combined information in response to occurrence of at least one of: an event where the received external input signal is changed, an event where a content provided through the display is changed and an event occurring at a predetermined time.
