1. A receiving device comprising:
receiver circuitry configured to
receive transmission video data via a transmission path, the transmission video data having a high dynamic range in which the transmission video data was processed by applying gamma characteristics to input video data;
circuitry configured to:
execute a conversion process on the transmission video data based on conversion characteristics information received together with the transmission video data to obtain converted video data in which the conversion characteristics information includes a type information indicating a type of conversion characteristics from a plurality of types of conversion characteristics;
convert a high-level side level range of the transmission video data such that a maximum luminance value of the converted video data becomes a level lower than a maximum luminance value of the received transmission video data based on auxiliary information received together with the transmission video data, the auxiliary information being extractable by the receiving device before processing the transmission video data in which the auxiliary information is included with each frame of the transmission video data; and
a display having a luminance dynamic range determinable based on EDID of the display to be sent through HDMI;
wherein said auxiliary information includes a data field defining a luminance level of a monitor.
