Abstract:
Corrupted subdivisions of streaming data are concealed using a matching subdivision in a previously reconstructed reference picture. The matching subdivision is located by applying a recovered motion vector to a co-located subdivision in the reference picture. The recovered motion vector is obtained using a reference motion vector from an available neighboring subdivision of the corrupted subdivision.
