Sisvel yakazivisa kugadzirwa kwepatent dziva rinovhara matekinoroji anopindirana nemahara AV1 uye VP9 vhidhiyo encoding mafomati. Sisvel inyanzvi mukutonga kwezvivakwa zvehungwaru, kuunganidza zvikwereti uye kuendesa nyaya dzepatent (patent troll, nekuda kwemabasa ayo kugovera kweOpenMoko kuvaka kwaifanira kumiswa kwenguva pfupi).
Kunyangwe mafomati eAV1 neVP9 asingade kubhadharwa patent, Sisvel iri kuunza chirongwa chayo chekupa marezenisi, pasi peiyo vagadziri vemidziyo inotsigira AV1 vachafanira kubhadhara makumi matatu nemaviri eurocents pachigadzirwa chimwe nechimwe chine skrini uye gumi nerimwe eurocents pachishandiso chega chega chisina skrini. VP32 huwandu hwehumambo hunotsanangurwa pa11 uye 9 euro masendi, zvichiteerana). Vanoronga kuunganidza mari kubva kune chero zvishandiso zvinoisa uye decode vhidhiyo muAV24 uye VP8 mafomati.
Padanho rekutanga, kufarira kukuru kuchave kwakabatana nekuunganidzwa kwemari kubva kune vanogadzira nharembozha, smart TV, set-yepamusoro mabhokisi, multimedia nzvimbo uye makomputa ega. Mune ramangwana, kuunganidzwa kwemari kubva kune vanogadzira software encoder hakugone kubviswa. Panguva imwecheteyo, izvo zvirimo pachazvo muAV1 uye VP9 mafomati, masevhisi ekuchengetedza uye kuendesa zvirimo, pamwe nemachipi uye akaiswa mamodule anoshandiswa mukugadzirisa zvirimo haazove pasi pemari.
Dziva reSisvel patent rinosanganisira mapatents kubva kuJVC Kenwood, NTT, Orange SA, Philips naToshiba, iyo zvakare inotora chikamu muMPEG-LA patent madziva akagadzirwa kuti atore mari kubva mukuitwa kweAVC, DASH uye HEVC mafomati. Rondedzero yematende anosanganisirwa mumadziva emvumo ane chekuita neAV1 uye VP9 haisati yaburitswa, asi yakavimbiswa kuburitswa pawebhusaiti yechirongwa cherezinesi mune ramangwana. Izvo zvakakosha kuti uzive kuti Sisvel haasi iye muridzi wematendi; inongobata mapatent evechitatu mapato.
Ngatiyeukei kuti kupa mahara kushandiswa kweAV1, iyo Open Media Alliance yakagadzirwa, iyo yakabatanidzwa nemakambani akadai seGoogle, Microsoft, Apple, Mozilla, Facebook, Amazon, Intel, AMD, ARM, NVIDIA, Netflix uye Hulu, iyo yakapa vashandisi veAV1 rezinesi rekushandisa mahara pamatendi ayo anopindirana neAV1. Matemo echibvumirano cherezinesi reAV1 anopawo kubviswa kwekodzero dzekushandisa AV1 kana zvichemo zvepatent zvichiunzwa kune vamwe vashandisi veAV1, i.e. makambani haakwanise kushandisa AV1 kana aine chekuita nematare edzimhosva kune vashandisi veAV1. Iyi nzira yekudzivirira haishande kune patent trolls seSisvel, sezvo makambani akadaro haaitise mabasa ekusimudzira kana kugadzira, uye hazvigoneke kuvamhan'arira vachipindura.
Muna 2011, mamiriro akafanana akaonekwa: MPEG LA yakaedza kuumba dziva repatent kuti iunganidze mari yeVP8 codec, iyo zvakare yakamisikidzwa kuti inowanikwa mahara. Panguva iyoyo, Google yakakwanisa kusvika pachibvumirano neMPEG LA uye yakawana kodzero yekushandisa pachena uye marezenisi emahara eMPEG LA anovhara VP8.
