Patent ID: 8831102

Claim:
A method for concealing a lost or damaged block of an enhanced spatial layer frame, said method comprising: using reference information from a lower spatial layer frame corresponding to said enhanced spatial layer frame for determining a reference frame in an enhanced spatial layer, said reference frame having a timestamp different from a timestamp of said enhanced spatial layer frame comprising said lost or damaged block; down-scaling said reference frame; obtaining a lower spatial layer frame approximation of said lower spatial layer frame by motion-compensating said down-scaled reference frame using motion information which corresponds to said lower spatial layer frame; obtaining a residual of said lower spatial layer frame, which corresponds to said lost or damaged block; obtaining a resulting frame by combining said lower spatial layer frame approximation with said residual of said lower spatial layer frame; and concealing said lost or damaged block of said enhanced spatial layer frame by upscaling a lower layer block approximation of said resulting frame.
