1. A reception device comprising:
reception circuitry configured to receive a description and a first video stream including encoded image data of first image data and encoded image data of second image data, and a second video stream including encoded image data of third image data and encoded image data of fourth image data, wherein:
the first image data is for acquisition of image data of a first frame rate and a first resolution, the second image data is for acquisition of image data of a second frame rate and the first resolution based on the first image data, the third image data is for acquisition of image data of the first frame rate and a second resolution based on the first image data, and the fourth image data is for acquisition of image data of the second frame rate and the second resolution based on the first, second, and third image data,
the description indicates a first representation corresponding to the first video stream and a second representation corresponding to the second video stream,
the first video stream includes a first temporal layer for the encoded image data of the first image data and a second temporal layer for the encoded image data of the second image data,
the second video stream includes a third temporal layer for the encoded image data of the third image data and a fourth temporal layer for the encoded image data of the fourth image data, and
the first frame rate is lower than the second frame rate, and the first resolution is lower than the second resolution; and
processing circuitry configured to obtain image data for display by decoding encoded image data included in the first and second video streams based on the description.
