Zusammenfassung:	The present invention relates to a real-time caption scrolling detecting apparatus and a method thereof, where a caption decoder is disclosed for decoding a sub picture unit (SPU) stream to obtain a first caption compressed data and a second caption compressed data for generating a first caption data and a second caption data correspondingly before transmitting the two obtained caption compressed data to a receiver for a detecting module to detect the first caption compressed data and the second caption compressed data and yield a deviation for judging a caption scrolling information of the second caption data in comparison with the first caption data.
