Signaling Scalability Information in a Parameter Set

Abstract

A system for decoding a video bitstream includes receiving a frame of the video that includes at least one slice and at least one tile and where each of the at least one slice and the at least one tile are not all aligned with one another.

1 .- 12 . (canceled) 
     
     
         13 . A method for decoding a coded video sequence comprising:
 receiving a first bitstream representative of a base layer of a coded video picture;   receiving a second bitstream representative of an enhancement layer of the coded video picture;   receiving first source scan type indicator for the base layer and a second source scan type indicator for the enhancement layer, each of the first and second source scan type indicators indicating a source scan type for the corresponding layer;   decoding the base layer based on the first source scan type indicator;   decoding the enhancement layer based on the second source scan type indicator; and   generating a decoded video sequence based on the base layer and the enhancement layer.   
     
     
         14 . The method of  claim 13 , wherein the first source type indicator indicates an interlaced scan type for the base layer. 
     
     
         15 . The method of  claim 13 , wherein the first source type indicator indicates a progressive scan type for the base layer. 
     
     
         16 . The method of  claim 13 , wherein the first source type indicator indicates an unknown scan type for the base layer. 
     
     
         17 . The method of  claim 13 , wherein the second source type indicator indicates an interlaced scan type for the enhancement layer. 
     
     
         18 . The method of  claim 13 , wherein the second source type indicator indicates a progressive scan type for the enhancement layer. 
     
     
         19 . The method of  claim 13 , wherein the second source type indicator indicates an unknown scan type for the enhancement layer.
