Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a new technique for subtitle region detection which operates without full-decoding for MPEG bitstreams. As the feature values for the detection, we focus on a variation of the reference frame for B-picture macroblocks (MBs) and the DCT coefficients for I-picture DCT block. These values are fed into a Markov Model(MM) as a temporal sequence to detect the subtitle regions from its state transition. The experimental results given in this paper show that our technique gives about 74.7% and 94.3% of the recall and the precision ratios, respectively, for some test sequences
