FIELD: data processing.
SUBSTANCE: invention relates to the field of transmission and reception of video data for performing photoelectric conversion of high dynamic range (HDR) video data, compressing the level range, and transmitting the resulting data. It has been proposed to perform a corresponding photoelectric conversion of video data from the HDR in accordance with the image context and transmit the resulting data, wherein the video data of the transmission is obtained by performing a photoelectric conversion of the input video data having a range of 0 to 100 %*N, where N is greater than 1. Container is transmitted that includes a video stream obtained by encoding the transmission video data. Information on the characteristic of the electro-optical conversion of each predetermined video data transmission unit is inserted into the video stream layer and/or the container level, and a given module is a scene module or a program module.
EFFECT: providing photoelectric conversion of HDR video data in accordance with the image content.
