QoMEX (Multimeedia Kogemuse Kvaliteedi) konverentsil esitati \u00fches ettekandes video kodeerimisformaadi AV2 testimistulemused, mille arendamisega tegeleb Open Media (AOMedia) liit ning mis asendab formaat AV1. VMAF (Video Multi-Method Assessment Fusion) kvaliteedi hindamise meetodite kasutamisel, mille on v\u00e4lja t\u00f6\u00f6tanud Netflix, v\u00f5imaldas AV2 kodeki kasutamine bitikiirusel v\u00e4hendada 32,59% v\u00f5rreldes AV1 kodekiga samas kvaliteedinivoo juures. PSRN-YUV (Sise-Signaali ja M\u00fcra Suhe 14:1:1) m\u00f5\u00f5tude kasutamisel \u00f5nnestus bitikiirus alandada 28,63%. Testimisel kasutati AVM 11.0 versiooni koos AV2 referentsrakendusega.

\"AV2-koodek<\/center> <\/p>\n

AV2 videokodeerimisformaat ei n\u00f5ua litsentsitasusid ning v\u00f5imaldab tasuta kasutada sellega seotud tehnoloogiaid, patente ja intellektuaalomandit. AV2 omadused: optimeerimine voogedastuse rakenduseks; m\u00e4rkimisv\u00e4\u00e4rne j\u00f5udluse paranemine v\u00f5rreldes AV1-ga tihendamise operatsioonides; laiem tugi virtuaalse ja liitreaalsuse v\u00f5imalustele; laiem visuaalse kvaliteedi toimetamise tugi; v\u00f5imalus edastada samaaegselt mitut videot \u00fche videovoo raames, toetades nende eraldiseisvat kuvamist ekraanil.

\"AV2-koodek<\/center> <\/p>\n

AV2 j\u00e4tkab h\u00fcbriidset plokip\u00f5hist struktuuri, kuid erinevalt AV1-st toetab see suuremaid superplokke 256\u00d7256, t\u00e4ielikku rekursiivset osaku (partitioning) ja t\u00f5husamat heleduse ja v\u00e4rvi parameetrite eraldamist. AV2-s on kasutusel \u00fchtne eksponentsiaalne kvantiseerija, mis katab laiemat heleduse vahemikku ja tagab suurema kvantiseerimise t\u00e4psuse 8-, 10- ja 12-bitise video puhul ning haldab paremini madalaid bitim\u00e4\u00e4rasid. <\/p>\n

T\u00f5hustatud on raamidevaheliste muutuste prognoosimise v\u00f5imalusi, mis paremini modelleerivad heleduse ja v\u00e4rvuse muutust, arvestavad mudeli koostamisel kuni 7 eelnevat raami, toetavad ajastatud (temporal) interpoleerimist ning paremini t\u00f6\u00f6tlevad liikumist HD-videos v\u00f5i kiiresti muutuvates sisudes. Lisatud on t\u00e4iendavad filtrid m\u00fcrade v\u00e4hendamiseks, tihendamise artefaktide v\u00e4hendamiseks ja detailide s\u00e4ilitamiseks. T\u00f6\u00f6 AV2 koodeki ja selle viidatud rakenduse kallal on juba l\u00f5petatud, kuid spetsifikatsiooni tuleb veel viimistleda, mille l\u00f5plik versioon plaanitakse avaldada aasta l\u00f5pus.
