Abstract:
To enable subtitles (graphics) to be favorably superimposed and displayed on video.
A container in a predetermined format is received, the container including a video stream having video data and a subtitle stream having subtitle data. The video stream is decoded to acquire the video data. The subtitle stream is decoded to acquire bitmap data of subtitles. Processing of correcting at least one of a size of the subtitles and a display position of the subtitles, is performed to the bitmap data of the subtitles. The bitmap data of the subtitles to which the processing has been performed, is superimposed on the video data to acquire display video data.
