Abstract
A method for automatically changing caption display style based on program content is disclosed. Plural caption parameters for each program content type are pre-defined. When a TV program is switched, a program system information protocol (PSIP) is searched to confirm program content type of the TV program. Captions of the TV program are decoded using a caption decoder based on program content type and corresponding caption parameters and the captions of the TV program are displayed according to the caption parameters relating to the program content type.
