To transmit ultra-high-definition image data with high frame rate along with preferable backward compatibility on the reception side.Ultra-high-definition image data with high frame rate is processed to obtain image data in a base format for obtaining a high-definition image with base frame rate, image data in a first extension format for obtaining an ultra-high-definition image with base frame rate, and image data in a second extension format for obtaining an ultra-high-definition image with high frame rate. A base video stream including encoded image data of the image data in the base format, and two or one extended video stream including encoded image data of the image data in the first extension format and encoded image data of the image data in the second extension format are generated. A container in a predetermined format including the base stream and the extended video streams is transmitted.
