Abstract

3D HDR content is packed for delivery compatible with multiple output formats. First and second processed versions of the content are generated from a first eye perspective portion of the 3D content. Third and fourth processed versions of the content are generated from a second eye perspective portion of the 3D content. From the first processed version of the content, a fifth processed version of the content is generated comprising a SDR version of the first processed version of the content. From the fourth processed version of the content, a sixth processed version of the content is generated comprising a SDR version of the fourth processed version of the content. The fifth and third processed versions of the content are placed in a base layer of the delivery format and the second and sixth processed versions of the content are placed into an enhancement layer of the delivery format.
