Kampani yoyang'anira katundu wanzeru Vectis IP yalengeza za kukhazikitsidwa kwa dziwe lovomerezeka laukadaulo logwiritsidwa ntchito mu Opus audio codec yaulere. Zaka 10 zapitazo, Opus idakhazikitsidwa (RFC 6716) ndi Internet Engineering Task Force (IETF) ngati codec yomvera pamapulogalamu a intaneti omwe safuna chindapusa cha chilolezo komanso samasokoneza ukadaulo wa eni ake. Vectis IP ikufuna kusintha chiphaso cha laisensi ya codec iyi ndipo yayamba kuvomera zofunsira kuchokera kumakampani omwe ali ndi ma patent omwe amalumikizana ndiukadaulo wa Opus.
Pambuyo pakupanga dziwe la patent, akukonzekera kuyang'ana kusonkhanitsa ndalama zamtengo wapatali kwa opanga zida za hardware zomwe zimathandizira Opus. Kupereka zilolezo sikungakhudze kukhazikitsa kotseguka kwa codec, kugwiritsa ntchito, ntchito ndi kugawa zomwe zili. Omwe anali ndi ma patent oyamba kulowa nawo anali Fraunhofer ndi Dolby. Zikuyembekezeka kuti m'miyezi ikubwera dziwe la ma patent opitilira zana lipangidwa ndipo opanga adzaitanidwa kuti apereke chilolezo chogwiritsa ntchito Opus codec pazida zawo. Kuchuluka kwa malipiro kudzakhala 15-12 eurocents kuchokera ku chipangizo chilichonse.
Zikudziwika kuti kuwonjezera pa mawonekedwe a Opus, Vectis IP ikugwira ntchito nthawi imodzi pakupanga maiwe a patent omwe amaphimba matekinoloje ena okhudzana ndi kujambula zithunzi ndi mavidiyo, mauthenga, e-commerce ndi makompyuta.
Opus codec imapangidwa pophatikiza matekinoloje apamwamba kwambiri kuchokera ku codec ya CELT yopangidwa ndi Xiph.org ndi SILK codec yotsegulidwa ndi Skype. Kuphatikiza pa Skype ndi Xiph.Org, makampani monga Mozilla, Octasic, Broadcom ndi Google nawonso adagwira nawo ntchito yopanga Opus. Opus imakhala ndi ma encoding apamwamba komanso latency yotsika pamawu omvera komanso kuphatikizika kwamawu pama foni a VoIP omwe ali ndi bandwidth. M'mbuyomu, Opus idazindikirika ngati codec yabwino kwambiri mukamagwiritsa ntchito 64Kbit bitrate (Opus idapambana opikisana nawo monga Apple HE-AAC, Nero HE-AAC, Vorbis ndi AAC LC). Kukhazikitsidwa kwa encoder ya Opus ndi decoder kuli ndi chilolezo pansi pa layisensi ya BSD. Mawonekedwe athunthu amapezeka pagulu, aulere, ndipo amavomerezedwa ngati mulingo wapaintaneti.
Ma Patent onse omwe amagwiritsidwa ntchito mu Opus amaperekedwa ndi makampani omwe akutenga nawo gawo kuti agwiritse ntchito mopanda malire popanda kulipira malipiro - ma Patent amaperekedwa kwa ofunsira ndi zinthu zomwe amagwiritsa ntchito Opus, popanda kufunikira kowonjezera. Palibe zoletsa pakukula kwa ntchito komanso kupanga njira zina za gulu lachitatu. Komabe, maufulu onse operekedwa amachotsedwa pakakhala milandu yokhudza patent yomwe ikukhudzana ndiukadaulo wa Opus motsutsana ndi aliyense wogwiritsa ntchito Opus. Ntchito ya Vectis IP ikufuna kupeza ma patent omwe amalumikizana ndi Opus, koma sakhala ndi makampani omwe adachita nawo chitukuko, kuyimitsa ndi kukwezedwa.
