Claim 10:
11. A method, comprising:
reconstructing a first reference frame and a second reference frame using frame data encoded to a bitstream to which an encoded frame is also encoded;
determining a concatenated motion vector representing a motion trajectory intersecting the first reference frame, the second reference frame, and the encoded frame by concatenating motion vectors signaled within the bitstream and associated with the first reference frame and the second reference frame;
interpolating a co-located reference frame for decoding the encoded frame using motion information from a motion field estimate determined based on the concatenated motion vector and using pixel information from the first reference frame and the second reference frame, wherein the co-located reference frame is co-located with the encoded frame; and
performing an inter-prediction process for decoding the encoded frame using a motion vector derived using the co-located reference frame.
