Title
(EN) An apparatus, a method and a computer program for video coding and decoding

Abstract
(EN)
There is provided a method comprising encoding an uncompressed constituent frame into a first encoded picture, said encoding also resulting into a reconstructed first picture and said constituent frame having an effective picture area within the first reconstructed picture, performing either of the following as a part of said encoding: inserting at least one sample value outside the effective picture area to form a boundary extension for the constituent frame in the reconstructed first picture; or saturating or wrapping over sample locations outside the effective picture area to be within the effective picture area. There is also provided a method comprising receiving an encoded picture, decoding the encoded picture to form a reconstructed constituent frame of the picture having an effective picture area; and performing either of the following: filling an area outside the effective picture area to produce a padded reference picture, wherein the filled area forms a boundary extension; or determining that when referring to sample locations outside the effective picture area in decoding, said sample locations are saturated or wrapped over to be within the effective picture area.

Keksinnön kohteena on menetelmä, joka käsittää yhden tiivistämättömän osakehyksen koodaamisen ensimmäiseen koodattuun kuvaan, mainitun koodaamisen johtaessa myös ensimmäiseen rekonstruoituun kuvaan ja mainitun osakehyksen käsittäessä vaikuttavan kuva-alueen ensimmäisen rekonstruoidun kuvan sisällä, joka suorittaa jompaa kumpaa seuraavista osana mainittua koodausta: lisätään ainakin yksi näytearvo vaikuttavan kuva-alueen ulkopuolelle muodostamaan rajalaajennuksen osakehykselle ensimmäisessä rekonstruoidussa kuvassa; tai kuva-alueen ulkopuolella olevia näytepaikkoja kyllästetään tai kierretään kuvan toiselle puolelle, jotta pysyttäisiin vaikuttavan kuva-alueen sisällä. Keksinnön kohteena on myös menetelmä, joka käsittää koodatun kuvan vastaanottamisen, koodatun kuvan dekoodaamisen muodostamaan rekonstruoidun osakehyksen vaikuttavan kuva-alueen käsittävästä kuvasta; ja suorittaa jommankumman seuraavista: täytetään vaikuttavan kuva-alueen ulkopuolinen alue laajennetun viitekuvan aikaansaamiseksi, jolloin täytetty alue muodostaa rajalaajennuksen; tai määritellään kun viitataan vaikuttavan kuva-alueen ulkopuolisiin näytesijanteihin dekoodauksessa, että mainitut näytesijainnit on kyllästetty tai kierretty kuvan toiselle puolelle, jotta pysytään vaikuttavan kuva-alueen sisällä.
