Abstract

A találmány tárgyát videoinformáció kódolására szolgáló eljárásképezi, amelynél aktuális videoinformáció egy darabját makroblokkokraosztják, és egy bizonyos számú rendelkezésre álló makroblokk-szegmentálást definiálnak egy makroblokk blokkokra valószegmentálására. Emellett minden egyes rendelkezésre álló makroblokk-szegmentáláshoz legalább egy rendelkezésre álló előrejelző eljárástdefiniálnak, amely előrejelző eljárások mindegyike a makroblokkonbelüli blokkokhoz előrejelzett mozgásegyütthatókat állít elő, és ígyegy bizonyos véges számú rendelkezésre álló makroblokk-szegmentálás-előrejelző eljáráspárt kapnak. Egy makroblokkhoz a rendelkezésre állómakroblokk-szegmentálás-előrejelző eljárás párok egyikét kiválasztják,majd ezután a makroblokkot blokkokra szegmentálják, és a makroblokkonbelüli blokkokhoz előrejelzett mozgásegyütthatókat állítanak elő akiválasztott makroblokk szegmentálás-előrejelző eljárás párfelhasználásával. A találmány tárgya továbbá a kódolt videoinformációdekódolására szolgáló eljárás, videoinformáció mozgáskompenzáltkódolására szolgáló kódoló és számítógépes programelem, a kódoltvideoinformáció dekódolására szolgáló kódoló és számítógépesprogramelem, továbbá a kódolót tartalmazó tárolóeszköz, mobil állomásés hálózati elem, valamint a dekódolót tartalmazó mobil állomás is.
