The above-described various displays for displaying the current state of the mobile terminal 100 may need to be progressed in the process of displaying a broadcast image through the display module 151 of the mobile terminal 100. For example, there may be a case of displaying a text message received while watching a broadcast through the mobile terminal 100, or a menu of the mobile terminal 100 being executed.

In displaying the functions of the mobile terminal 100 except for the display of the broadcast video, the display of the function may interfere with viewing of the broadcast video. For example, a case where a predetermined area or more of the display module 151 is devoted for displaying a text message may be used. If a text message is displayed while the broadcast video is displayed, the display of the broadcast video may be restricted.

If the display of the broadcast video is limited, the step S40 of outputting the sub-audio may proceed.

The broadcast signal received through the broadcast receiving module 111 of FIG. 1 may include broadcast video and broadcast audio as described above. On the other hand, the broadcast voice may include a voice multiplexing signal for voice multiplexing.

Voice multicasting means a case in which a plurality of broadcast voices are included in one broadcast video. For example, when the broadcast video is a foreign currency, it may be a case where a main voice dubbed in Korean and a sub-voice including the voice of an actor before dubbing are received together. In such a case, the user can operate the mobile terminal 100 appropriately, and selectively listen to the main voice and the sub-audio according to his / her preference. It may be voice according to (DVS, Descriptive Video Service).

Screen-narration broadcasting is a broadcasting service that includes sub-voices that describe broadcasting video by voice for the visually impaired. In the case of the visually impaired, broadcast video cannot be watched intact. Therefore, for the visually impaired, the voice actor describes the screen that is currently being broadcast in the screen commentary broadcasting. For example, if the current scene is depicting a scene where the door is opened from inside the actor's room, the screen commentary may describe a voice commentary such as "Tae Hee chooses clothes while looking around the store." Can be. In addition to the actors' voices, various visually recognizable situations are represented by voices of the voice actors, so that the screen commentary broadcasting is gradually expanding for the visually impaired to watch the broadcasting smoothly, and is being forced as part of the law.

As shown in FIG. 7A, a first pop-up window P1 may be displayed informing that the text message has arrived while the user is watching the broadcast video B. FIG.

As shown in FIG. 7B, the second pop-up window P2 displaying the text message M may be displayed to overlap some screens other than the entire screen of the display module 151. Since the second pop-up window P2 covers the broadcast video B to a certain extent, the user can smoothly watch the broadcast. Therefore, even in such a case, the screen commentary broadcast S may be output. Since the screen commentary broadcast (S) is output, the user can watch the broadcast simultaneously with the confirmation of the text message (M).

8 is a diagram illustrating the operation of a mobile terminal according to another embodiment of the present invention.

As shown in FIG. 8A, a user may watch a broadcast image through the display module 151. The user who was watching the broadcast image may flip the mobile terminal 100 in the rotation direction (R). When the mobile terminal 100 is turned over, the display module 151 faces the ground, so that the user cannot watch the broadcast image in the normal state.

As illustrated in FIG. 8B, even when the display module 151 of the mobile terminal 100 faces the ground, the screen description broadcast S may be output through the sound output module 152 of FIG. 1. That is, even when the mobile terminal 100 is in any state, it means that viewing of the broadcast may not be limited. In this state, the controller 180 of FIG. 1 may block power supply to the display module 151. That is, the display module 151 is turned off. The display module 151 is turned off but the broadcast can be heard by voice. Therefore, the same effect as watching a broadcast can be achieved while minimizing battery consumption.
