Transmission apparatus, transmission method, reception apparatus, and reception method

A reception apparatus, comprising:

• receiving circuitry configured to receive a container, containing a basic video stream, having encoded image data of image data, having a basic format, from which an image having a high definition at a basic frame rate is to be obtained, and one or more enhancement video streams containing encoded image data of:
• (i) image data, having a first enhancement format, from which image having the high definition at a high frame rate is to be obtained, (ii) image data, having a second enhancement format obtained based on at least the image data having the basic format, from which an image at the basic frame rate is to be obtained, and (iii) image data, having a third enhancement format obtained based on at least the image data having the first enhancement format, from which an image having at the high frame rate is to be obtained;
• and
• processing circuitry configured to process only the basic video stream to obtain image data having the high definition at the basic frame rate, or process a part of or a whole of the one or more enhancement video streams to obtain image data having the high definition at the high frame rate or image data having the basic frame rate,
• wherein image data having the basic format is obtained by mixing processing at a first ratio in units of two temporally consecutive pictures in image data having the high frame rate to obtain first image data as image data at the basic frame rate,
• wherein the image data having the first enhancement format obtained by mixing processing at a second ratio in units of two temporally consecutive pictures in image data at the high frame rate to obtain second image data as image data having an enhancement frame at the high frame rate,
• wherein the spatial scalability information is inserted into the encoded image data of the image data having the second and the third enhancement formats, or a container position corresponding to the encoded image data, and temporal scalability information is inserted into the encoded image data of the image data having the first and the third enhancement formats, or the container position corresponding to the encoded image data.

A reception method, comprising:

• receiving, by receiving circuitry of a reception apparatus, a container containing a basic video stream, having encoded image data of image data, having a basic format, from which an image having a high definition at a basic frame rate is to be obtained, and one or more enhancement video streams containing encoded image data of (i) image data, having a first enhancement format, from which image having the high definition at a high frame rate is to be obtained, (ii) image data, having a second enhancement format obtained based on at least the image data having the basic format, from which an image having an ultra-high definition at the basic frame rate is to be obtained, and (iii) image data, having a third enhancement format obtained based on at least the image data having the first enhancement format, from which an image having the ultra-high definition at the high frame rate is to be obtained;
• and
• processing, by processing circuitry of the reception apparatus, only the basic video stream to obtain image data having the high definition deformation at the basic frame rate, or processing a part of or a whole of the one or more enhancement video streams to obtain image data having the high definition at the high frame rate or image data having the basic frame rate,
• wherein the image data having the basic format is obtained by mixing processing at a first ratio in units of two temporally consecutive pictures in image data having the high frame rate to obtain first image data as image data at the basic frame rate,
• wherein the image data having the first enhancement format obtained by mixing processing at a second ratio in units of two temporally consecutive pictures in image data at the high frame rate to obtain second image data as image data having an enhancement frame at the high frame rate,
• wherein the spatial scalability information is inserted into the encoded image data of the image data having the second and the third enhancement formats, or a container position corresponding to the encoded image data, and temporal scalability information is inserted into the encoded image data of the image data having the first and the third enhancement formats, or the container position corresponding to the encoded image data.
