Abstract

A decoding method of a video stream, which is encoded video information. The video stream includes a base video stream, and an enhanced video stream, which is a video stream to enhance luminance of the base video stream, and a describer that contains the combination information of the base video stream and the enhanced video stream. The decoding method includes acquiring the describer, and identifying the combination of the base video steam and the enhanced video stream. The decoding method also includes generating base video information by decoding the base video stream, generating enhanced video information by decoding the enhanced video stream, generating decoded video information based on the base video stream and the enhanced video stream, and outputting the decoded video information.
