摘要

PROBLEM TO BE SOLVED: To achieve more efficient video hierarchy encoding by properly applying a processing for achieving high resolution to a basic decoded video signal obtained by decoding basic encoding data to produce a prediction video signal highly correlative with an original video signal.;SOLUTION: A video hierarchy encoding device 100 is capable of more properly generating the prediction video signal by providing a filtering part 210 which extracts a high frequency component corresponding to the original video signal from the basic decoded video signal to produce a high frequency component signal in the preceding stage of inter-hierarchy prediction processing when performing spacial interpolation from a basic layer to an extension layer.;COPYRIGHT: (C)2010,JPO&INPIT
