Claim Text:
1. A method for coding video data, the method comprising: coding syntax elements of a parameter set that identify candidate long-term reference pictures of the video data, wherein one or more of the candidate long-term reference pictures belong in a reference picture set of a current picture of the video data, and one or more of the candidate long-term reference pictures do not belong in the reference picture set of the current picture, and wherein the reference picture set identifies reference pictures of the video data that can potentially be used for inter-predicting the current picture of the video data and can potentially be used for inter-predicting one or more pictures of the video data following the current picture in decoding order; coding syntax elements that indicate which candidate long-term reference pictures, identified in the parameter set, belong in the reference picture set of the current picture; constructing at least one of a plurality of reference picture subsets based on the indication of which candidate long-term reference pictures belong in the reference picture set of the current picture, wherein the plurality of reference picture subsets form the reference picture set, wherein a first plurality of reference picture subsets identifies reference pictures that can potentially be used for inter-predicting the current picture and pictures following the current picture in decoding order and a second plurality of reference picture subsets identifies reference pictures that cannot be used for inter-predicting the current picture and can potentially be used for inter-predicting pictures following the current picture in decoding order; constructing one or both of a first reference picture list and a second reference picture list based on one or more reference pictures of the first plurality of reference picture subsets; and inter-predicting the current picture of the video data based on at least one reference picture identified in the first reference picture list or the second reference picture list.
