1. A transmission device, comprising circuitry configured to:
perform a first mixing process on two temporally-consecutive first pictures in high-frame-rate image data to obtain basic image data, a first mixing ratio of the first mixing process being p to q, p and q being numbers, p being greater than or equal to 0 and smaller than or equal to 1, a sum of p and q being equal to 1, and a second mixing process on two temporally-consecutive second pictures in the high-frame-rate image data to obtain extended image data, a second mixing ratio of the second mixing process being r to s, r and s being numbers, r being greater than or equal to 0 and smaller than or equal to 1, a sum of r and s being equal to 1;
perform an encoding process to encode the basic image data to obtain basic encoded image data, and to encode the extended image data to obtain extended encoded image data; and
transmit the basic encoded image data, the extended encoded image data, and mixing ratio information indicating the first mixing ratio.
