Abstract: Provided is an image decoding device including an acquisition unit configured to acquire clean random access (CRA) information used to identify one or more CRA pictures in an image sequence inserted into a data region from a header region of a file format including the header region and the data region, a control unit configured to specify one CRA picture in the image sequence as a decoding start picture using the CRA information when an instruction of random access is detected, and a decoding unit configured to decode the image sequence from the decoding start picture specified by the control unit.

Abstract: Provided is an image encoding device including circuitry configured to generate a file with clean random access (CRA) information, which identifies CRA pictures in the image and which is set in a header region of a file that includes the header region and a data region within which a series of encoded image data associated with actual data of the image is stored, wherein the file is an MP4 format file, wherein the CRA information is sample group information grouping a plurality of CRA pictures, wherein the CRA information includes previous picture information used to identify a previous picture which is previous to each CRA picture in a presentation order and is not encoded normally at a time of random access to the CRA picture, and wherein output of the previous picture from the image encoding device is skipped based on the previous picture information.

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.
