Abstract
The present technology ensures that electrooptical conversion processing for transmission video data obtained using an HDR optoelectrical conversion characteristic is favorably carried out at a receiving side. The transmission video data is obtained by performing high dynamic range optoelectrical conversion on high dynamic range video data. A video stream is obtained by applying encoding processing to this transmission video data. A container in a predetermined format including this video stream is transmitted. Meta information indicating an electrooptical conversion characteristic corresponding to a high dynamic range optoelectrical conversion characteristic is inserted into a parameter set field in the video stream.
