Pashure pemakore anenge mashanu ebudiriro vhidhiyo itsva encoding standard H.266, inozivikanwawo seVVC (Versatile Video Coding). H.266 inonzi yakatsiva H.265 (HEVC), yakagadzirwa pamwe chete nemapoka anoshanda (ISO/IEC JTC 1) uye (ITU-T), nekutora chikamu kwemakambani akaita seApple, Ericsson, Intel, Huawei, Microsoft, Qualcomm uye Sony. Kuburitswa kwereferensi yekushandiswa kweiyo encoder uye decoder yeH.266/VVC inotarisirwa mukudonha.
H.266 / VVC inopa kushandiswa kwepamusoro kwepamusoro uye kuchengetedza zvigadziriso zvose zvekrini (kubva kuSD uye HD kusvika ku4K uye 8K), inotsigira vhidhiyo ine simba rakawedzerwa (HDR, High Dynamic Range) uye panoramic video mu 360-degree mode. YCbCr nzvimbo yeruvara inotsigirwa ne4:4:4 uye 4:2:2 chromatic shanduko, kudzika kwemavara kubva pa10 kusvika 16 bits pachiteshi, uye ebetsero machanera data senge kudzika uye pachena.
Kuenzaniswa neH.265 (HEVC), chiyero chitsva chinoratidza kuwedzera kukuru kwehuwandu hwekugadzirisa uye inobvumira, pamabitrate akafanana, kuderedza huwandu hwemashoko akatumirwa neanenge 50% pasina kurasikirwa kwemufananidzo. Semuenzaniso, kana yevhidhiyo yemaminitsi makumi mapfumbamwe muUHD quality muH.90 zvaive zvakakodzera kuendesa 265 GB yedata, ipapo H.10 inokubvumira kuti usangane ne266 GB uchichengetedza hutano hwakafanana. Kuenzanisa, iyo AV5 fomati maererano nekumanikidza kusimba HEVC paavhareji ne17% (pahupamhi hwebitrate ne30-43%).
Mutengo wekuwedzera kudzvinyirira kunonyanya kukosha kwealgorithms, zvichiita kuti kuwedzere kudiwa kwekombiyuta zviwanikwa (kusvika ku10 nguva dze encoding uye kusvika ku2 nguva dzekugadzirisa zvichienzaniswa neH.265). Kusiyana neAV1 video encoding format, kushandisa H.266/VVC muzvigadzirwa zvako zvinoda kubhadhara mari. Kupa marezinesi emvumo anopindirana nechiyero, sangano reMC-IF (Media Coding Industry Forum) rakavambwa, iro rinosanganisira makambani nemasangano anodarika makumi matatu ane pfuma yenjere inoshandiswa muH.30/VVC.
