Intellectual Property Management kambani Vectis IP yakazivisa kuumbwa kwepatent dziva kune rezinesi matekinoroji anoshandiswa mumahara odhiyo codec Opus. Makore gumi apfuura, Opus yakamisikidzwa (RFC 10) neInternet Injiniya Task Force (IETF) sekodeki yekuteerera yeInternet application isingade muripo werezinesi uye isingakanganise tekinoroji yevaridzi. Vectis IP inoda kushandura mamiriro ekupihwa rezenisi rekodhi iyi uye yatanga kutambira zvikumbiro kubva kumakambani ane marezinesi anopindirana neOpus tekinoroji.
Mushure mekugadzirwa kwedziva repatent, vanoronga kutarisa kuunganidzwa kwemari kune vanogadzira zvigadzirwa zvehardware zvinotsigira Opus. Kupihwa rezinesi hakuzokanganisa yakavhurika codec kuita, maapplication, masevhisi uye kugovera zvemukati. Vekutanga vane patent kujoina chirongwa ichi vaive Fraunhofer naDolby. Zvinotarisirwa kuti mumwedzi iri kuuya dziva rezvibvumirano zvinopfuura zana richaumbwa uye vagadziri vachakokwa kuti vape rezinesi rekushandisa Opus codec mumidziyo yavo. Mari yehumambo ichave 15-12 eurocents kubva kune yega yega mudziyo.
Zvinocherechedzwa kuti pamusoro peiyo Opus fomati, Vectis IP iri kushanda panguva imwe chete pakuumbwa kwepatent madziva anofukidza mamwe matekinoroji ane hukama nemufananidzo uye vhidhiyo kukodha, kutaurirana, e-commerce uye komputa network.
Iyo Opus codec inogadzirwa nekubatanidza matekinoroji akanakisa kubva kuECLT codec yakagadziriswa neXiph.org uye iyo SILK codec yakavhurwa neSkype. Mukuwedzera kune Skype uye Xiph.Org, makambani akadai seMozilla, Octasic, Broadcom neGoogle akatorawo chikamu mukugadzirwa kweOpus. Opus inoratidzira yakakwira encoding mhando uye yakaderera latency kune ese ari maviri akakwira-bitrate kutenderera odhiyo uye nezwi compression mubandwidth-inomanikidzirwa VoIP telephony application. Pakutanga, Opus yaizivikanwa seyakanakisa codec kana uchishandisa 64Kbit bitrate (Opus yakarova kunze vakwikwidzi vakaita seApple HE-AAC, Nero HE-AAC, Vorbis uye AAC LC). Iwo mareferenzi ekuita eOpus encoder uye decoder ane rezinesi pasi peiyo BSD rezinesi. Iwo akazara mafomati anotsanangurwa anowanikwa pachena, emahara, uye anotenderwa seyero yeInternet.
Ese patents anoshandiswa muOpus anopihwa nemakambani ari kutora chikamu chekushandisa zvisina kurambidzwa pasina kubhadharwa kwemari - patent anopihwa otomatiki kune zvikumbiro uye zvigadzirwa zvinoshandisa Opus, pasina kudiwa kwekuwedzera kubvumidzwa. Iko hakuna zvirambidzo pahukuru hwekushandisa uye kugadzirwa kweimwe nzira yechitatu-bato kuita. Zvakadaro, kodzero dzese dzakapihwa dzinokanzurwa kana pakaitika nyaya dzepatent dzinosanganisira tekinoroji yeOpus kune chero mushandisi weOpus. Chiitiko cheVectis IP chakanangana nekutsvaga patents anopindirana neOpus, asi asiri emakambani akatanga kubatanidzwa mukusimudzira, kumisikidza uye kusimudzira.
