Abstract: A video is recorded on a recording medium so that a reproducing apparatus can faithfully reproduce an original color of the recorded video. An sRGB color space or an extended sRGB color space is specified as the color space of the video to be recorded. A signal processing unit generates a video signal corresponding to the specified color space. An encoding/decoding unit compresses the video signal in accordance with the MPEG4-AVC standard to generate a compressed video signal. A CPU generates a color space identifier including information indicating the color space specified and is configured so that an access unit including an SPS NAL unit in the compressed video signal includes an SEI NAL unit in which the color space identifier is stored. The video recorded on the recording medium includes the color space identifier having information for a color space of that video.

Abstract translation: 视频被记录在记录介质上，使得再现设备可以忠实地再现记录的视频的原始颜色。 将sRGB颜色空间或扩展的sRGB颜色空间指定为要记录的视频的颜色空间。 信号处理单元产生对应于指定颜色空间的视频信号。 编码/解码单元根据MPEG4-AVC标准压缩视频信号以产生压缩视频信号。 CPU生成颜色空间标识符，其包括指示指定的颜色空间的信息，并且被配置为使得包括压缩视频信号中的SPS NAL单元的访问单元包括其中存储颜色空间标识符的SEI NAL单元。 记录在记录介质上的视频包括具有该视频的颜色空间的信息的颜色空间标识符。
