Abstract
Concepts for signaling visual content are described. According to one aspect, a picture representing a projection of a volumetric representation onto a projection plane is provided in a bitstream along with a geometric representation of the projection plane. According to a further aspect, a regions of a composed picture signaled in a bitstream are associated with a number of pictures of a number of projections of objects. According to a further aspect, regions of a composed picture signaled in a bitstream are associated with respective information types of a picture.
Claims7
A non-transitory digital storage medium having stored thereon a bitstream for signaling visual content, comprising
- a representation of a picture, which represents a projection of a volumetric representation of an object onto a projection plane, which is positioned in a 3D space, from the perspective of a view position in the 3D space, and
- a geometric representation of the projection plane in the 3D space,
- wherein the geometric representation is indicative of a position and an orientation of the projection plane in the 3D space, wherein the geometric representation is indicative of an orientation of the projection plane with respect to a straight line between the view position and the projection plane.
An apparatus for processing a bitstream, configured to retrieve, from the bitstream,
- a representation of a picture, which represents a projection of a volumetric representation of an object onto a projection plane, which is positioned in a 3D space, from the perspective of a view position in the 3D space, and
- a geometric representation of the projection plane in the 3D space, wherein the geometric representation is indicative of a position and an orientation of the projection plane in the 3D space, wherein the geometric representation is indicative of an orientation of the projection plane with respect to a straight line between the view position and the projection plane.
