摘要:
A video encoder with an integrated temporal filter, which has an output carrying a sequence of encoded frames, includes: an input receiving input frame data; a temporal filter receiving the input frame data from the input and producing filtered frame data; motion processing modules receiving reconstructed frames derived from the sequence of encoded frames and the filtered frame data from the temporal filter and producing a residual error signal output; and a coder module which receives the input frame data and the residual error signal and produces the sequence of encoded frames. A method of encoding video includes: receiving a current frame to be encoded into a motion estimator and a temporal filter substantially at one time; receiving a previously encoded reference frame; generating a reconstructed motion-compensated reference frame from the previously encoded reference frame; and determining from the motion-compensated reference frame and the current frame whether and how much blending to perform between the motion compensated reference frame and the current frame.
