Recording apparatus, recording method, image pickup apparatus, reproducing apparatus and video system

摘要

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.

主权项

1. A reproduction apparatus, comprising:
a reproducing circuit configured to
acquire a video stream including a video signal corresponding to a predetermined color space from a recording medium, the video stream including one or more sequences as edit units,
each of the sequences including a plurality of access units,each of the access units including a predetermined number of Network Abstraction Layer (NAL) units,when the predetermined color space is a particular color space, the access units include a Supplemental Enhancement Information (SEI) NAL unit including a color space identifier which includes information corresponding to the particular color space, andthe information corresponding to the particular color space includes at least color space information, color gamut information including maximum and minimum values of the color gamut, and color precision information specifying a precision of the color gamut, andreproduce the video signal and the color space identifier recorded on the recording medium; and an interface circuit that sends the video signal and the color space identifier reproduced by the reproducing circuit to a network at a predetermined transfer timing.
