Abstract:
To reduce a processing load on a receiving side upon superimposition of a subtitle graphics data on video data. A video stream with the video data is generated. A subtitle stream with bitmap data obtained by conversion of the subtitle graphics data is generated. A container containing the video stream and the subtitle stream is transmitted. The subtitle stream contains a first segment having a bitmap conversion table with color gamut and/or brightness conversion information. On the receiving side, the bitmap data is merely converted into the subtitle graphics data by means of the bitmap conversion table to that the subtitle graphics data with characteristics conformable to characteristics of superimposition target video data can be easily obtained.

Claim (Index 17):
A receiving method comprising:\n a receiving step of receiving, by a receiving unit, a container containing a video stream with video data and a subtitle stream with bitmap data obtained by conversion of subtitle graphics data, wherein the subtitle stream contains a first segment having a bitmap conversion table with color gamut and/or brightness conversion information, and a control step is further provided, the control step controlling, by a control unit, processing of decoding the video stream to obtain the video data, processing of decoding the subtitle stream to obtain the bitmap data and the bitmap conversion table, processing of converting the bitmap data into the subtitle graphics data by means of the bitmap conversion table, and processing of superimposing the subtitle graphics data on superimposition target video data obtained on the basis of the video data.
