摘要：
A data output apparatus includes: a video decoder that decodes a video stream to generate a first video signal; an external metadata acquisition unit that acquires one or more pieces of metadata corresponding to one or more first conversion modes; an HDR metadata interpreter that interprets one of the one or more pieces of metadata to acquire characteristic data and conversion auxiliary data; a DR converter that supports one or more second conversion modes and performs conversion processing of a luminance range of the first video signal based on the conversion auxiliary data to generate a second video signal; and an HDMI output unit that outputs the second video signal to a display apparatus.
