Abstract

Systems and methods for bi-directional temporal error concealment are described. In one aspect, a lost frame is detected during encoded video decoding operations. Bi-directional estimations for each pixel of the lost frame are calculated to generate a current frame for bi-directional temporal error concealment of the lost frame.
