Abstract: Systems and methods for coding video data are disclosed. The method can include determining a reference picture set (RPS) for a current picture based on one or more reference pictures. The method can also include determining a picture order count (POC) value of each reference picture of the RPS and identifying at least one of a number of long-term reference pictures and a number of short-term reference pictures within the RPS. The method can also include applying constraints to the number of long-term pictures and the number of short-term pictures in the RPS, the constraints being based on the POC value and a maximum decoded picture buffer size minus one, if a video sequence parameter (VPS) extension is in use. The method can include generating at least one syntax element identifying the RPS based on the constraints and encoding the current picture based on the at least one syntax element.

Abstract: A video encoder generates, based on a reference picture set of a current view component, a reference picture list for the current view component. The reference picture set includes an inter-view reference picture set. The video encoder encodes the current view component based at least in part on one or more reference pictures in the reference picture list.

The video decoder generates, based on the reference picture set, the reference picture list for the current view component. In addition, the video decoder decodes at least a portion of the current view component based on one or more reference pictures in the reference picture list.

Abstract: 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.
