Pyramid decoding device for loss cell concealment in progressive transmission

摘要

The present invention relates to a pyramid decoding apparatus for concealing lost cells in progressive transmission, the apparatus including a lower layer and a higher layer decoding unit for decoding first and second packet data transmitted through a transmission channel, And the layer decoding unit reconstructs the lost video region corresponding to the lost cell of the transmitted second packet using a motion vector up-scaled from the frame buffer / motion compensation unit in the upper layer decoding unit.
