摘要： In one example, this disclosure describes a method of decoding a frame of video data comprising a plurality of block-sized coding units including one or more largest coding units (LCUs) that include a hierarchically arranged plurality of relatively smaller coding units. In this example, the method includes determining a granularity at which the hierarchically arranged plurality of smaller coding units has been split when forming independently decodable portions of the frame. The method also includes identifying an LCU that has been split into a first section and a second section using the determined granularity. The method also includes decoding an independently decodable portion of the frame that includes the first section of the LCU without the second section of the LCU.

摘要： The example techniques of this disclosure are directed to default construction techniques for the construction of a combined reference picture list, and default mapping techniques for the combined reference picture list. In some examples, a video coder may construct first and second reference picture lists from frame number values, and construct the combined reference picture list from the frame number values of the first and second reference picture lists. In some examples, a video coder may construct first and second reference picture lists from picture order count (POC) values, and construct the combined reference picture list from the POC values of the first and second reference picture lists. In some examples, a video coder may construct a combined reference picture list from received information for the construction, and map the pictures of the combined reference picture list to one of a first or second reference picture list.

摘要： This disclosure relates to techniques for constructing a combined reference picture list, List C, based on List 0 and List 1, used for uni-directional prediction of video blocks in any direction. The techniques include coding one or more syntax elements defined to indicate construction information for List C, and performing reference picture list construction for List C from List 0 and List 1 based on the syntax elements. The one or more syntax elements may indicate that List C is used for uni-directional prediction, and may also indicate a number of reference pictures identified in List C and a reference index of a reference picture for each entry in List C. Each coded video block of a B slice may have an associated syntax element, i.e., inter_pred_idc, to indicate whether the video block is bi-predicted from List 0 and List 1 (Bi) or uni-directional predicted from List C (Pred_LC).
