U-Sisvel umemezele ukudalwa kwechibi lelungelo lobunikazi elimboza ubuchwepheshe obudlulana nefomethi yamahhala yombhalo wekhodi wevidiyo ye-AV1 ne-VP9. I-Sisvel igxile ekuphathweni kwempahla yengqondo, ukuqoqa izimali ezizuzwayo kanye nokufaka amacala obunikazi (i-patent troll, ngenxa yemisebenzi yayo ukusatshalaliswa kwezakhiwo ze-OpenMoko kudingeke ukuthi kumiswe okwesikhashana).
Nakuba amafomethi e-AV1 kanye ne-VP9 engadingi izimali zelungelo lobunikazi, i-Sisvel yethula uhlelo lwayo lokunikeza amalayisense, lapho abakhiqizi bamadivayisi asekela i-AV1 kuyodingeka bakhokhe ama-euro angu-32 ngocingo ngalunye olunesikrini kanye nama-euro angu-11 kudivayisi ngayinye ngaphandle kwesikrini (for VP9 inani lobukhosi elichazwe kumasenti angama-euro angama-24 no-8, ngokulandelana). Bahlela ukuqoqa izinzuzo kunoma imaphi amadivaysi afaka ikhodi futhi aqophe ividiyo ngamafomethi we-AV1 ne-VP9.
Esigabeni sokuqala, isithakazelo esikhulu sizobe sihlobene nokuqoqwa kwezimali ezivela kubakhiqizi bamafoni omakhalekhukhwini, ama-smart TV, amabhokisi abekwe phezulu, izikhungo ze-multimedia kanye namakhompyutha omuntu. Ngokuzayo, ukuqoqwa kwezimali ezivela kubathuthukisi besifaki khodi sesofthiwe ngeke kukhishwe. Ngesikhathi esifanayo, okuqukethwe ngokwako kumafomethi we-AV1 ne-VP9, izinsizakalo zokugcina nokuletha okuqukethwe, kanye nama-chips namamojula ashumekiwe asetshenziswa ekucubunguleni okuqukethwe ngeke abe ngaphansi kwezimali ezizuzwayo.
I-Sisvel patent pool ihlanganisa amalungelo obunikazi avela ku-JVC Kenwood, NTT, Orange SA, Philips kanye ne-Toshiba, ephinde ibe neqhaza kumachibi obunikazi be-MPEG-LA adalelwe ukuqoqa izinzuzo ezivela ekusetshenzisweni kwefomethi ye-AVC, DASH ne-HEVC. Uhlu lwamalungelo obunikazi afakwe kumachibi obunikazi ahlobene ne-AV1 kanye ne-VP9 awakadalulwa, kodwa kuthenjiswe ukuthi luzoshicilelwa kuwebhusayithi yohlelo lokunikeza ilayisense esikhathini esizayo. Kubalulekile ukuqaphela ukuthi u-Sisvel akayena umnikazi wamalungelo obunikazi, ulawula kuphela amalungelo obunikazi bezinkampani zangaphandle.
Masikhumbule ukuthi ukuhlinzeka ngokusetshenziswa kwamahhala kwe-AV1, kwasungulwa i-Open Media Alliance, eyajoyinwa izinkampani ezifana ne-Google, Microsoft, Apple, Mozilla, Facebook, Amazon, Intel, AMD, ARM, NVIDIA, Netflix kanye ne-Hulu, inikeze abasebenzisi be-AV1 ilayisense yokusebenzisa mahhala amalungelo obunikazi ayo agqagqana ne-AV1. Imigomo yesivumelwano selayisensi ye-AV1 iphinde ihlinzekele ngokuhoxiswa kwamalungelo okusebenzisa i-AV1 uma kwenzeka izimangalo zelungelo lobunikazi zilethwa kwabanye abasebenzisi be-AV1, i.e. izinkampani azikwazi ukusebenzisa i-AV1 uma zibandakanyeka ezinyathelweni zomthetho ezibhekiswe kubasebenzisi be-AV1. Le ndlela yokuvikela ayisebenzi kuma-patent troll afana no-Sisvel, njengoba izinkampani ezinjalo azenzi imisebenzi yentuthuko noma yokukhiqiza, futhi akunakwenzeka ukuzimangalela uma ziphendula.
Ngo-2011, isimo esifanayo sabonwa: I-MPEG LA yazama ukwakha i-patent pool ukuze iqoqe izinzuzo ze-codec ye-VP8, nayo ebekwe njengetholakalayo ukusetshenziswa mahhala. Ngaleso sikhathi, i-Google yakwazi ukufinyelela esivumelwaneni ne-MPEG LA futhi yazuza ilungelo lokusebenzisa esidlangalaleni kanye namalungelo obunikazi angenazo izinzuzo aphethwe yi-MPEG LA ehlanganisa i-VP8.
