 that is not an anchor access unit. H.3.25 non-anchor picture: A coded picture that is not an anchor picture. H.3.26 non-anchor view component: A view component that is not an anchor view component. H.3.27 non-base view: A view that is not the base view. VCL NAL units of a non-base view have nal_unit_type equal to 20. Decoding of view components in a non-base view may require the use of inter-view prediction. H.3.28 non-reference picture: A view component coded with nal ref idc equal to 0. A non-reference picture is not used for inter prediction in the decoding process of any other view components. H.3.29 operation point: An operation point is identified by a temporal_id value representing the target temporal level and a set of view id values representing the target output views. One operation point is associated with a bitstream subset, which consists of the target output views and all other views the target output views depend on, that is derived using the sub-bitstream extraction process as specified in clause H.8.5.3 with IdTarget equal to the temporal_id value and viewIdTargetList consisting of the set of view id values as inputs. More than one operation point may be associated with the same bitstream subset. When the specification states "an operation point is decoded" it refers to the decoding of a bitstream subset corresponding to the operation point and subsequent output of the target output views. H.3.30 picture order count: A variable that is associated with each field view component and each field of a frame view component and has a value that is non-decreasing with increasing field position in output order in the same view relative to the first output field of the previous IDR view component in decoding order in the same view or relative to the first output field of the previous view component, in decoding order in the same view, that contains a memory management control operation that marks all reference pictures in the view as "unused for reference". H.3.31 prefix NAL unit: A NAL unit with nal_unit
