Video data bitstreams may contain bitstream conformance parameters, such as hypothetical reference decoder (HRD) parameters, which may be used to allow a decoder to test the conformance of a received bitstream. In multi-layer codecs transmitted using partitions, the video data may be associated with one or more layer sets. Each layer set may be associated with one or more output layer sets. Each output layer set may be further associated with one or more partitioning schemes. Conformance parameters are mapped to partitions of a partitioning scheme, based upon the output layer set that the partitioning scheme is associated with. This allows for a partition to be associated with different conformance parameters, depending upon the output layer set that is being used.
