Claim 0:
1. A reception device comprising:
reception circuitry configured to receive:
a base stream and an enhanced stream, the base stream including image data of each picture of a base layer obtained by performing a mixing process on image data of pairs of temporally consecutive pictures at a predetermined frame rate, and encoding the image data of each picture of the base layer, and the enhanced stream including image data of each picture of an enhanced layer obtained by extracting image data of one picture of each pair of temporally consecutive pictures, and encoding the image data of each picture of the enhanced layer, and
mixing process information indicating whether the mixing process is a linear or a non-linear mixing process; and

processing circuitry configured to:
decode the base stream to obtain the image data of each picture of the base layer,
decode the enhanced stream to obtain the image data of the one picture of each pair of temporally consecutive pictures,
perform an inverse mixing process on the image data of each picture of the base layer by using the image data of the one picture of each pair of temporally consecutive pictures to obtain image data of the other picture of each pair of temporally consecutive pictures, wherein the inverse mixing process is an inverse process of the mixing process and is a linear inverse mixing process or a non-linear inverse mixing process, and
perform the linear or the non-linear inverse mixing process in accordance with the mixing process information,

wherein at least one of:
the mixing process has been performed in a linear space before application of an opto-electronic conversion characteristic or a non-linear space after application of an opto-electronic conversion characteristic, or
the processing circuitry is configured to perform the inverse mixing process in a non-linear space before application of an electro-optical conversion characteristic or a linear space after application of an electro-optical conversion characteristic.
