Abstract

Keksinnön kohteena on ratkaisu koodausta ja koodinpurkua varten, jossa keksinnössä määritetään intra-ennustussuunta ensimmäiselle koodausyksikölle; mainittua ensimmäistä koodausyksikköä varten muodostetaan aktiivisten vertailunäytteiden taulukko määrittämällä etäisyysmitta mainitun ensimmäisen koodausyksikön ja etäisten vertailunäytteiden taulukon välillä; määrittämällä ainakin yhden mainittuun etäisten vertailunäytteiden taulukkoon kuuluvan etäisen vertailunäytteen sijainti mainittua intra-ennustussuuntaa ja mainittua etäisyysmittaa käyttäen; ja lisäämällä mainittu ainakin yksi etäinen vertailunäyte mainittuun aktiivisten vertailunäytteiden taulukkoon. Intra-ennustusnäytteistä koostuva lohko muodostetaan käyttämällä mainittua intra-ennustussuuntaa ja mainittua aktiivisten vertailunäytteiden taulukkoa.
