Patent ID: 8634463

Claim:
A method of processing multimedia data, the method comprising: generating at least one interpolated frame by an encoder; identifying a plurality of reference frames comprising said interpolated frame and a plurality of non-interpolated frames by the encoder, wherein the plurality of reference frames comprises at least one list of reference frames, wherein the interpolated frame is at a specified position in the at least one list, and wherein the specified position identifies the frame in the specified position as an interpolated frame; and encoding at least a portion of a frame based at least on the plurality of reference frames by the encoder, wherein a same field in the encoded at least a portion of a frame is used to indicate encoding using one of the plurality of non-interpolated reference frames by indicating a position in the at least one list of reference frames other than the specified position, and to indicate encoding using the interpolated frame by indicating the specified position in the at least one list of reference frames, wherein encoding comprises generating encoding data indicative of an encoding mode and a residual pattern, wherein said encoding data is further indicative of whether the portion is encoded based on the interpolated frame.
