When converting a frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame or insert a third frame predicted from the first frame and the second frame between the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or three predicted frames. On the other hand, it is also possible to maintain the input frame rate without additional conversion.

The formatter 360 receives the output signal of the frame rate converter 355 and changes the format of the signal to be suitable for the display unit 180 and outputs the signal. For example, the R, G, B data signals may be output, and the R, G, B data signals may be output as low voltage differential signaling (LVDS) or mini-LVDS.

The voice processing unit (not shown) in the controller 170 may perform voice processing of the demultiplexed voice signal. To this end, the voice processing unit (not shown) may include various decoders.

The speech processing unit (not shown) in the controller 170 may decode the demultiplexed speech signal if it is an encoded speech signal. For example, the demultiplexed speech signal may be decoded by an MPEG-2 decoder, or an MPEG 4 decoder, or an AAC decoder, or an AC-3 decoder.

Also, the voice processing unit (not shown) in the controller 170 may process a base, a treble, a volume control, and the like.

The data processor (not shown) in the controller 170 may perform data processing of the demultiplexed data signal. For example, when the demultiplexed data signal is an encoded data signal, it may be decoded. The encoded data signal may be EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted in each channel. For example, the EPG information may be ATSC-PSIP (ATSC-Program and System Information Protocol) information in the case of the ATSC scheme, and may include DVB-Service Information (DVB-SI) in the case of the DVB scheme. . The ATSC-PSIP information or the DVB-SI information may be information included in the aforementioned stream, that is, the header (4 bytes) of the MPEG-2 TS.

For example, the image display device 1001 that is playing content may include a character or a prop on the screen. In this case, the object includes an object that is separated from other characters or props, such as a character or a prop included in the screen, and exists independently.

The user may input an object selection command included in the screen of the image display device 1001 to the image display device 1001. The video display device 1001 receives an object selection command in operation S1010. In the present embodiment, the user of the image display device 1001 may input an object selection command to the image display device 1001 by using a remote control device. For example, when the remote controller is a spatial remote controller, the image display device 1001 may display a pointer corresponding to a signal transmitted from the spatial remote controller on the screen. The signal transmitted from the spatial remote control corresponds to the movement of the spatial remote control. The user can move the spatial remote control so that the movement trajectory of the pointer includes a predetermined object. In this case, the image display device 1001 determines that an object selection command included in the movement trajectory is input to the image display device 1001.

In the present embodiment, when there are at least two objects included in the movement trajectory, the image display device 1001 may determine that an object selection command displayed at the center of the movement trajectory is input. In addition, the image display device 100 may determine that the object selection command that is most included in the movement trajectory is input.

The image display device 1001 determines keywords or attribute information to be searched based on the received signal (S1035). The video display device 1001 queries the search engine or the application providing server 1003 for keyword or attribute information (S1040).

The search engine or application providing server 1003 may transmit / receive signals with the image display device 1001 through wired or wireless Internet. A search engine is an engine that searches online information related to a keyword or attribute information queried among information provided through the Internet. The application providing server 1003 is a server in which an application that can be installed and executed in the video display device 1001 is stored. The application providing server 1003 may search for information related to an application related to the queried keyword or attribute information (S1045).

The search engine or the application providing server 1003 may transmit a signal including the searched information to the image display device 1001 (S1050). The image display device 1001 displays a search result on the display unit based on the information included in the received signal (S1055). In this embodiment, the search result displayed by the image display device 1001 may be information searched through a search engine. In addition, the search result may be application related information provided through the application providing server 1003.
