Abstract
The invention is suitable for the technical field of digital television and provides a subtitle displaying method and system. The method comprises receiving television program code stream containing character type subtitles, converting the character type subtitles into images in the preset subtitle display type and displaying the images on a television. When the subtitles are manufactured, the character type subtitles and control orders are combined into data stream to be multiplexed with digital television programs. Thus, after a set top box receives television program code stream, the subtitle data can be converted into images in the preset character display type, and all images are controlled by the control orders to be displayed. The subtitle displaying method and system solves the problems that types of subtitles cannot be processed and effective data transmission is little in the prior art.
