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

A recording method comprising:

• processing a captured video stream to obtain a video signal corresponding to a predetermined color space, wherein,
• the video stream comprises one or more than one sequence which is an edit unit,
• each of the sequences comprises a plurality of access units,
• each of the access units comprises a predetermined amount of NAL (Network Abstraction Layer) units,
• when the predetermined color space is a particular color space, the access unit comprises SEI (Supplemental Enhancement Information) NAL unit which comprises information of the particular color space, and
• the information of the particular color space comprises at least information of color space, information of color gamut including a maximum value of the color gamut and a minimum value of the color gamut, and color precision information specifying a precision of the color gamut.

A recording apparatus including a recording processing unit that processes a captured video signal to record a video signal on a non-transitory recording medium, and a reproduction processing unit that reproduces the video signal recorded on the non-transitory recording medium and that sends the video signal to a network, wherein:

• the recording processing unit includes:
• a video signal processing unit that processes the captured video stream to obtain a video signal corresponding to a predetermined color space,
• the video stream comprises one or more than one sequence which is an edit unit,
• each of the sequences comprises a plurality of access units,
• each of the access units comprises a predetermined amount of NAL (Network Abstraction Layer) units,
• when the predetermined color space is a particular color space, the access unit comprises SEI (Supplemental Enhancement Information) NAL unit which comprises information of the particular color space, and
• the information of the particular color space comprises at least information of color space, information of color gamut including a maximum value of the color gamut and a minimum value of the color gamut, and color precision information specifying a precision of the color gamut, and
• the reproduction processing unit includes:
• a reproducing unit that reproduces the video signal and color space identifier recorded on the non-transitory recording medium, and
• a network interface that sends the video signal and color space identifier reproduced by the reproducing unit to the network.
