FIELD: information technology.
SUBSTANCE: invention relates to a transmission apparatus for transmitting video data, obtained by applying a gamma-distribution curve. Said result is achieved by applying a gamma curve to input video data having a level range from 0% to 100%*N, where N is greater than 1, to obtain video data for transmission that are transmitted together with auxiliary information used for converting a high-luminance level on a receiving side. High-level side level range of the transmission video data is converted at the receiving side such that, a maximum level becomes a predetermined level based on auxiliary information received together with the transmission video data.
EFFECT: technical result consists in reproducing an image with an appropriate luminance dynamic range at the receiving side.
