RECEPTION DEVICE, RECEIVING METHOD, TRANSMISSION DEVICE, AND TRANSMITTING METHOD |
摘要 |
The technology is directed to keeping high image quality when a subtitle is superimposed on a video. A reception device includes circuitry configured to receive a video stream and a subtitle stream. The circuitry processes the video stream to obtain video data of a video. The circuitry processes the subtitle stream to obtain subtitle bitmap data of a subtitle bitmap image. The circuitry adjusts a color gamut of the subtitle bitmap data to a color gamut of the video data. The color gamut of the subtitle bitmap data is adjusted based on color gamut identification information of the subtitle bitmap data and color gamut identification information of the video data. The circuitry further superimposes, on the video, the color gamut adjusted subtitle bitmap image. |
