Method and apparatus for decoupling frame number and/or picture order count (POC) for multi-view video encoding and decoding
There is disclosed and described a decoder and decoding method for decoding at least one picture corresponding to at least one of at least two views of multi-view video content from a bitstream, wherein in the bitstream at least one of coding order information and output order information for the at least one picture is decoupled from the at least one view to which the at least one picture corresponds. Furthermore, there is disclosed and described an encoder and encoding method for encoding at least one picture corresponding to at least one of at least two views of multi-view video content to form a resultant bitstream, wherein in the resultant bitstream at least one of coding order information and output order information for the at least one picture is decoupled from the at least one view to which the at least one picture corresponds.
1. An apparatus for multi-view video encoding, comprising:
an encoder for encoding at least one picture corresponding to at least one of at least two views of multi-view video content to form a resultant bitstream,
wherein in the resultant bitstream at least one of coding order information and output order information for the at least one picture is determined and is decoupled from the at least one view to which the at least one picture corresponds,
wherein said encoder determines the at least one of the coding order information and output order information for the at least one picture based on a view identifier and the view identifier is present at a level higher than a macroblock level in the resultant bitstream;
wherein said encoding step encodes the at least one of the at least two views using redefined variables in a default reference picture list construction process and reference picture list reordering process,
wherein a Group Of Pictures length is used to redefine the variables;
wherein coding order information is redefined as frame_num*N+view_id whereas output order information is redefined as PicOrderCnt(picX)*N+view_id, where frame_num is representative of coding order information, PicOrderCnt is representative of output order information, N is a number of views and view_id is the view identifier; and,
wherein said encoder includes the view identifier in the resultant bitstream for use by a decoded reference picture marking process.
2. A method for multi-view video encoding, comprising:
encoding at least one picture corresponding to at least one of at least two views of multi-view video content to form a resultant bitstream,

wherein said encoding step determines the at least one of the coding order information and output order information for the at least one picture based on a view identifier and the view identifier is present at a level higher than a macroblock level in the resultant bitstream;
wherein said encoding step encodes the at least one of the at least two views using redefined variables in a default reference picture list construction process and reference picture list reordering process,
wherein a Group Of Pictures length is used to redefine the variables;
wherein coding order information is redefined as frame_num*N+view_id whereas output order information is redefined as PicOrderCnt(picX)*N+view_id, where frame_num is representative of coding order information, PicOrderCnt is representative of output order information, N is a number of views and view_id is the view identifier; and,
wherein said encoding step includes the view identifier in the resultant bitstream for use by a decoded reference picture marking process.
