Zusammenfassung:	The invention relates to encoding and decoding images. According to an aspect of the invention HCVQ codevectors are formed in a receiving terminal. A group of codevectors forms a codebook, and a group of codebooks forms a codebook library. Only a VQ codebook and a certain number of modification vectors are sent to the receiving terminal. The compressed HCVQ vectors are formed using the received VQ and modification vectors.
