In one embodiment, a method includes determining motion parameters for a temporally-located block to a current block of video content. The temporally-located block is located in a different picture from the current block. The temporally-located block is identified in a merge mode candidate list. The merge mode candidate list includes candidate blocks in which motion parameters are candidates to be used for the current block. The method then signals information to a decoder to indicate which motion parameters from a candidate block on the merge mode candidate list to use in decoding the current block. If a temporally-located block is identified, the method uses motion parameters for the temporally-located block in decoding the current block of video content.
