The voice information extraction module 220 may extract voice information included in the broadcast signal and convert the voice information into character information. It can be understood that the subtitle information extraction module 210 performs the same function as the subtitle information extraction module 210 except that it detects an event using audio information. Therefore, the voice information extraction module 220 may further include a separate component such as a voice recognition processor (not shown) for converting voice information into character information, 300).

As described above, the program information extracting unit 200 can extract the caption information and the audio information, and the viewer can set which of the caption information and the audio information to use. Therefore, when caption information is included according to a program, and most events included in the program are described as caption information, it is effective to use the caption information.

On the contrary, in the case of the professional baseball relay program of the foregoing example, it is preferable to detect the issue event by extracting the audio information because the event is often described by the description of the transcriber rather than the caption information.

The above description is merely an example for facilitating understanding of the present invention, and it may be possible to set which one of the subtitle information or the audio information is used to detect an event according to a viewer's preferred method.

As described above, the comparison determining unit 300 compares the information input to the receiving unit 100 with the caption information or the voice information received from the program information extracting unit 200 to determine occurrence of an issue event A method for accurately determining this may be required.

There may be a case where the event is predicted with a separate caption before the actual issue event is broadcasted. This may degrade the accuracy in judging occurrence of the issue event using the caption information.

Such notice may be made not only by the caption information but also by the voice of the broadcast operator, which may also be a problem when judging occurrence of an issue event using voice information.

In the case of sports broadcast broadcasting, since the past game and the main scene of the game are often inserted in the middle of the game, the audio information included in such a scene may also be an obstacle to accurate judgment.

Therefore, when the occurrence of an artifact event is determined using the caption information, the caption information displayed in the bottom of the screen is treated as meaningless information, and only the information of the caption displayed at a specific position on the screen is used as valid information It is possible to apply a method for recognizing the user.

In addition, when the occurrence of an artifact event is determined using audio information, a method of recognizing the artifact only when the audio information including the main word is repeated twice or more within a predetermined time may be applied.
