Inkampani yolawulo lwepropathi yobukrelekrele iVectis IP ibhengeze ukusekwa kwechibi lelungelo elilodwa lomenzi wechiza kwilayisenisi yetekhnoloji esetyenziswa kwi-codec ye-audio ye-Opus yasimahla. Iminyaka eyi-10 eyadlulayo, i-Opus yayisemgangathweni (i-RFC 6716) yi-Intanethi ye-Intanethi ye-Intanethi ye-Intanethi (IETF) njenge-codec yomsindo yezicelo ze-Intanethi ezingadingi mali zelayisensi kwaye ayiphazamisi itekhnoloji yobunini. I-Vectis IP ijonge ukutshintsha ubume belayisenisi yelungelo elilodwa lomenzi wechiza kule codec kwaye sele iqalisile ukwamkela izicelo ezivela kwiinkampani eziphethe amalungelo awodwa awodwa adibana ne-Opus technologies.
Emva kokuqulunqwa kwe-patent pool, baceba ukugxila kwingqokelela yemali yokuhlawula abenzi bezixhobo ze-hardware ezixhasa i-Opus. Ukukhutshwa kwelayisensi akuyi kuchaphazela ukuphunyezwa kwe-codec evulekileyo, izicelo, iinkonzo kunye nokuhanjiswa komxholo. Abanini bamalungelo awodwa abenzi bokuqala ukujoyina eli nyathelo yayinguFraunhofer kunye noDolby. Kulindeleke ukuba kwiinyanga ezizayo i-pool yamalungelo awodwa omenzi wechiza angaphezu kwekhulu kwaye abavelisi baya kumenywa ukuba banike ilayisenisi yokusetyenziswa kwe-Opus codec kwizixhobo zabo. Imali yobukhosi iya kuba yi-15-12 eurocents kwisixhobo ngasinye.
Kuphawulwe ukuba ukongeza kwifomathi ye-Opus, i-Vectis IP isebenze ngaxeshanye ekuqulunqweni kwamachibi e-patent agubungela obunye ubuchwephesha obunxulumene nomfanekiso kunye nekhowudi yevidiyo, unxibelelwano, i-e-commerce kunye neenethiwekhi zekhompyuter.
I-codec ye-Opus yenziwe ngokudibanisa iteknoloji engcono kakhulu kwi-codec ye-CELT ephuhliswe ngu-Xiph.org kunye ne-SILK codec evuliwe nge-Skype. Ukongeza kwi-Skype kunye ne-Xiph.Org, iinkampani ezifana ne-Mozilla, i-Octasic, i-Broadcom kunye ne-Google nayo yathatha inxaxheba ekuphuhliseni i-Opus. I-Opus inomgangatho ophezulu wokufakwa kweekhowudi kunye ne-latency ephantsi kuzo zombini i-bitrate ephezulu yokusasazwa komsindo kunye noxinzelelo lwelizwi kwi-bandwidth-inyanzelwe kwizicelo zefowuni zeVoIP. Ngaphambili, i-Opus yayisaziwa njengeyona codec ilungileyo xa usebenzisa i-bitrate ye-64Kbit (i-Opus yabetha abantu abakhuphisana nabo njenge-Apple HE-AAC, iNero HE-AAC, iVorbis kunye ne-AAC LC). Ukusetyenziswa kwereferensi ye-Opus encoder kunye nedikhowuda zinelayisensi phantsi kwelayisensi ye-BSD. Iinkcukacha ezipheleleyo zefomathi ziyafumaneka esidlangalaleni, simahla, kwaye zamkelwe njengomgangatho we-Intanethi.
Onke amalungelo awodwa omenzi wechiza asetyenziswa kwi-Opus anikezelwa ziinkampani ezithatha inxaxheba ukuze zisetyenziswe ngokungenamda ngaphandle kwentlawulo ye-royalty - amalungelo awodwa awodwa anikezelwa ngokuzenzekelayo kwizicelo kunye neemveliso zisebenzisa i-Opus, ngaphandle kwemfuneko yolwamkelo olongezelelweyo. Akukho zithintelo kububanzi besicelo kunye nokudalwa kolunye ukuphunyezwa komntu wesithathu. Nangona kunjalo, onke amalungelo anikezelweyo ayarhoxiswa kwimeko yesimangalo selungelo elilodwa lomenzi wechiza okubandakanya ubuchwepheshe be-Opus ngokuchasene naye nawuphi na umsebenzisi we-Opus. Umsebenzi we-Vectis IP ujolise ekufumaneni amalungelo awodwa omenzi wechiza adibana ne-Opus, kodwa ayizizo iinkampani ebezibandakanyeka ekuqaleni kuphuhliso, ukubekwa emgangathweni kunye nokukhuthaza.
