The invention provides a TV set with a point-reading function and a realizing method thereof, which is suitable for a TV set. The method comprises the following steps: a) sensing the clicking of a user on the point-reading content in a paper point-reading teaching material through a sensing device and transmitting clicking coordinate data to a TV set micro control unit (MCU), b) invoking video data corresponding to the point-reading content from the stored point-reading teaching material audio/video files through the TV set MCU according to the clicking coordinate data to a TV set video processing module and invoking audio data corresponding to the point-reading content to a TV set audio processing module, and c) displaying images corresponding to the point-reading content through a TV set display screen and playing the sound corresponding to the point-reading content through a TV set loudspeaker. The technical scheme of the invention ensures that the point-reading function can be realized through the TV set, the use cost of users is greatly lowered, and better audio/video effect can be obtained compared with the traditional point-reading machine.
