    摘要: A data playback method according to one aspect of the present disclosure is a data playback method for displaying a video in a first luminance range with graphics being superimposed on the video. The method includes: determining whether a playback device has a function for converting first graphics in a second luminance range narrower than the first luminance range to second graphics in the first luminance range; when the playback device has the function, causing the playback device to convert the first graphics to the second graphics and to display the video with the second graphics being superimposed on the video; and when the playback device does not have the function, causing the playback device to display the video with third graphics different from the second graphics being superimposed on the video.

    摘要: A decoding apparatus includes: a receiver that receives a transfer frame that stores a plurality of second transfer units that each contain one or more first transfer units obtained by multiplexing of content; and a decoder that acquires a plurality of first transfer units by decoding the transfer frame, the decoder outputting the plurality of first transfer units to a demultiplexing apparatus that acquires the content by demultiplexing the plurality of first transfer units. A first transfer unit positioned at a head within a second transfer unit positioned at a head within the transfer frame contains reference clock information. The decoder further generates information for identifying the first transfer unit positioned at a head, and outputs the information to the demultiplexing apparatus.

    摘要: A conversion method for converting luminance of a video, including a luminance value in a first luminance range, to be displayed on a display apparatus includes: acquiring a first luminance signal indicating a code value obtained by quantization of the luminance value of the video; and converting the code value indicated by the acquired first luminance signal into a second luminance value determined based on a luminance range of the display apparatus, the second luminance value being compatible with a second luminance range with a maximum value smaller than a maximum value of the first luminance range and larger than 100 nit. This provides the conversion method capable of achieving further improvement.
