Video signal coding apparatus and decoding apparatus.

摘要

In a predictive coding apparatus, an interframe/field predictive signal is generated which low frequency components are depressed. A predictive error signal is generated on the basis of an input video signal and the interframe/field predictive signal. The predictive error signal is then interframe/field-coded. In a predictive decoding apparatus, a code transmitted from the coding apparatus is interframe/field-decoded to obtain a decoded signal. An interframe/field predictive signal is generated which low frequency components are depressed. The video signal is then reproduced by adding the decoded signal and the predictive signal.
