摘要

In order to make images based on HDR video data display well on an LDR monitor, a prescribed level mapping curve is applied to input video data (HDR video data) having a first level range, to obtain transmission video data (LDR video data) having a second level range which is narrower than the first level range. The transmission video data is transmitted together with auxiliary information to enable performing the level conversion on the receiving side.
