A particular method includes accessing at least a portion of an encoded picture (614), the encoded picture being from a particular view of multiple views, and the portion being encoded at a particular resolution. The method further includes determining a particular view level based on the particular view (614), determining the particular resolution based on the particular view level (606), and decoding the portion based on the particular resolution (630). ## Claims ### Claim 1 A method, comprising: accessing at least a portion of an encoded picture, the encoded picture being from a particular view of multiple views, and the portion being encoded at a resolution; determining the resolution of the particular view for at least the portion from information identifying an assigned view level and a resolution corresponding to the view level; and decoding at least the portion based on the determined resolution, wherein the determining comprises identifying the resolution for the particular view based on a position of the view level in a scalability hierarchy, the position being indicated by a particular view level and the scalability hierarchy provides scalability at least by allowing that pictures from a given position in the scalability hierarchy to be used as an inter-view reference for pictures from a less important position in the scalability hierarchy and not to be used as a reference for pictures from a more important position in the scalability hierarchy, and resolution for a picture from a given position in the scalability hierarchy being as good as resolution for a picture from a less important position in the scalability hierarchy, and wherein inter-view reference pictures are downsampled from a higher resolution picture before being used as a reference for pictures from a less important position in the scalability hierarchy. ### Claim 2 (depends on 1) The method of claim 1, wherein: resolution for a picture from a given position in the scalability hierarchy is at least as good as resolution for a picture from a less important position in the scalability hierarchy. ### Claim 3 (depends on 1) The method of claim 1, wherein the determining of the particular resolution comprises: accessing an indicator from the information that indicates a view level position in a scalability hierarchy for the particular view; and determining the particular resolution based on the view level position in the scalability hierarchy. ### Claim 4 (depends on 3) The method of claim 3, wherein the encoded picture and the indicator are accessed from data formatted according to a particular video coding standard. ### Claim 5 (depends on 1) The method of claim 1, further comprising: accessing multiple encoded pictures, the multiple encoded pictures being from the particular view and being encoded at the particular resolution; and decoding the multiple encoded pictures based on the particular resolution. ### Claim 6 (depends on 5) The method of claim 5, wherein the multiple encoded pictures belong to one or more of a group of pictures, a scene, or a movie. ### Claim 7 An apparatus, comprising: a memory, and a processor, configured to: access at least a portion of an encoded picture, the encoded picture being from a particular view of multiple views, and the portion being encoded at a resolution; determine the resolution of the particular view for at least the portion from information identifying an assigned view level and a resolution corresponding to the view level; and decode at least the portion based on the determined resolution, wherein the determining comprises identifying the resolution for the particular view based on a position of the view level in a scalability hierarchy, the position being indicated by a particular view level and the scalability hierarchy provides scalability at least by allowing that pictures from a given position in the scalability hierarchy to be used as an inter-view reference for pictures from a less important position in the scalability hierarchy and not to be used as a reference for pictures from a more important position in the scalability hierarchy, and resolution for a picture from a given position in the scalability hierarchy being as good as resolution for a picture from a less important position in the scalability hierarchy, and wherein inter-view reference pictures are downsampled from a higher resolution picture before being used as a reference for pictures from a less important position in the scalability hierarchy.
