Abstract:
An object is to make it possible to perform caption display satisfactorily in a case where the caption display position is designated as a relative position. The video stream is decoded to obtain video data, and the subtitle stream including the caption information is decoded to obtain bitmap data of the caption. The caption display position in the caption display position information included in the caption information is designated as a relative position with respect to the caption display range. In a case where the aspect ratio of the video area is different from the aspect ratio of the display video area, the caption display position is determined with the display video area defined as the caption display range, further resize processing is performed, and the display position control is performed onto the bitmap data of the caption on the basis of the caption display position that has undergone the resize processing. Bitmap data of the caption that has undergone display position control is superimposed on the video data to obtain display video data.

Claim (Index 4):
A reception method comprising:\n a reception step, executed by a reception unit, of receiving a container containing a video stream including video data and a subtitle stream including caption information including caption display position information that designates a caption display position by a relative position with respect to a caption display range; and a control step, executed by a control unit, of controlling: video decode processing of decoding the video stream to obtain video data; subtitle decode processing of decoding the subtitle stream to obtain bitmap data of a caption; display position control processing, performed in a case where an aspect ratio of a video area is different from an aspect ratio of the display video area, of determining a caption display position on the basis of the caption display position information with a display video area defined as a caption display range, performing resize processing on the determined caption display position, and performing display position control on the bitmap data of the caption on the basis of the caption display position that has undergone the resize processing; and video superimposition processing of superimposing the caption bitmap data that has undergone the display position control, on the video data.
