Method for indicating coding order in multi-view video coded content

Abstract

There are provided methods and apparatus for improved signaling using high level syntax for multi-view video coding and decoding. An apparatus includes an encoder (100) for encoding at least one picture for at least one view corresponding to multi-view video content in a resultant bitstream, wherein said encoder signals video coding order information for at least the at least one picture in a high level syntax.

1 . A method for encoding multi-view video content, comprising:
 encoding at least one picture for at least one view corresponding to the multi-view video content into a bitstream having high level syntax information, said high level syntax information including:   a parameter representing a total number of coded views in the bitstream minus one; and   a view identifier indicated by a parameter, view_id[i],   wherein an encoding order of a view is indicated by index i, and said view_id[i] explicitly signals said view identifier of said view within said multi-view video content,   wherein index i ranges from 0 to the total number of coded views minus one, and   wherein said view_id[i] is an index other than the index i.   
     
     
         2 . The method of  claim 1 , wherein the view identifier for each of a plurality of views of said multi-view video content is assigned such that gaps are allowed between consecutive view identifiers. 
     
     
         3 . The method of  claim 1 , wherein the encoding order of said view is unique. 
     
     
         4 . The method of  claim 1 , wherein the view represented by the view identifier view_id[i] is the i th  view in the encoding order. 
     
     
         5 . An apparatus comprising one or more processors, wherein the one or more processors are configured to:
 encode at least one picture for at least one view corresponding to the multi-view video content into a bitstream having high level syntax information, said high level syntax information including:   a parameter representing a total number of coded views in the bitstream minus one;   a view identifier indicated by a parameter, view_id[i],   wherein an encoding order of a view is indicated by index i, and said view_id[i] explicitly signals said view identifier of said view within said multi-view video content,   wherein index i ranges from 0 to the total number of coded views minus one, and   wherein said view_id[i] is an index other than the index i.   
     
     
         6 . The apparatus of  claim 5 , wherein the view identifier for each of a plurality of views of said multi-view video content is assigned such that gaps are allowed between consecutive view identifiers. 
     
     
         7 . The apparatus of  claim 5 , wherein the encoding order of said view is unique. 
     
     
         8 . The apparatus of  claim 5 , wherein the view represented by the view identifier view_id[i] is the ith view in the encoding order. 
     
     
         9 . A non-transitory machine readable medium having stored thereon machine executable instructions that, when executed, implement an encoding method, the encoding method comprising:
 receiving a bitstream having said multi-view video content and high level syntax information;   decoding a parameter, in said high level syntax information, representing a total number of coded views in the bitstream minus one;   determining a view identifier and decoding order of a view within said multi-view video content from a parameter view_id[i] in said high level syntax information,   wherein the decoding order of said view is indicated by the index i, and said view_id[i] explicitly signals said view identifier of said view within said multi-view video content,   wherein index i ranges from 0 to the total number of coded views minus one, and   wherein said view_id[i] is an index other than the index i; and   decoding said view within said multi-view video content responsive to said decoding order.   
     
     
         10 . The medium of  claim 9 , wherein the view identifier for each of a plurality of views of said multi-view video content is assigned such that gaps are allowed between consecutive view identifiers. 
     
     
         11 . The medium of  claim 9 , wherein the encoding order of said view is unique. 
     
     
         12 . The medium of  claim 9 , wherein the view represented by the view identifier view_id[i] is the i th  view in the encoding order.
