This paper illustrates how to interpret the superimposed caption box (SCB) in broadcasted sports videos of which the SCB template is presumably not given as a priori. The embedded captions in sports video programs represent digested key information of the video content. Most of the previous studies assume that the SCB template and the character bitmaps are known. The major contributions of this paper are (1) caption template extraction and identification, (2) symbol extraction and modeling, and (3) semantic interpretation of the identified captions and symbols. Experimental results show that the algorithm performs the SCB contents understanding for several commercial sports video programs.
