Claim Text:
1. A method for coding video data, the method comprising: coding information indicative of reference pictures that belong to a reference picture set, wherein the reference picture set identifies the reference pictures that can potentially be used for inter-predicting a current picture and can potentially be used for inter-predicting one or more pictures following the current picture in decoding order; constructing a plurality of reference picture subsets that each identifies zero or more of the reference pictures of the reference picture set, wherein constructing the plurality of reference picture subsets comprises: after construction of the first, second, and third reference picture subsets, determining which reference pictures are usable for inter-prediction of the current picture based on which pictures are identified in the first, second, and third reference picture subsets; subsequent to determining which reference pictures are usable for inter-prediction of the current picture, constructing an initial reference picture list based on reference pictures in the first, second, and third reference picture subsets that are determined to be usable for inter-prediction of the current picture; and based on reference picture list modification of the initial reference picture list being needed after the construction of the initial reference picture list:
