Abstract: Provided are an apparatus and a method that are capable of performing reliable display control with no caption display interruption of the TTML caption data. Specifically, when a set value of the caption display end time specification attribute of the TTML caption data is the continuous display instruction value, memory storing and display processing of caption data currently displayed are continued even after reproduction end timing of an image file, and switching processing of TTML caption data files is performed. When a set value of the caption display start time specification attribute of the TTML caption data is the continuous display instruction value, whether or not there is a text string, display processing of the text string is continued, is determined, and when there is the text string, the displayed text is continuously displayed. With the processing, it is possible to achieve display control with no caption display interruption of the TTML caption data.
