Document Type and Number:
WIPO Patent Application WO/2017/043504
Kind Code:
A1
Abstract:
The present invention transmits normal frame rate and high frame rate image data satisfactorily. In the high frame rate image data, a mixing process at a first ratio is applied in units of two pictures contiguous in time and basic frame rate image data is obtained, and also a mixing process at a second ratio is applied in units of two pictures contiguous in time and extended image data having a high frame rate is obtained. An encoding process is applied to reference frame rate image data and a basic stream is obtained, and also an encoding process is applied to the extended frame image data having the high frame rate and an extended stream is obtained. A container of a prescribed format including the basic stream and the extended stream is transmitted.
