Ua hoʻolaha ʻo Vectis IP ʻoihana hoʻokele waiwai noʻonoʻo i ka hoʻokumu ʻana i kahi wai patent no ka laikini ʻenehana i hoʻohana ʻia i ka codec audio free Opus. 10 makahiki i hala aku nei, ua hoʻohālikelike ʻia ʻo Opus (RFC 6716) e ka Internet Engineering Task Force (IETF) ma ke ʻano he codec leo no nā noi pūnaewele ʻaʻole koi i nā uku laikini a ʻaʻole keakea i nā ʻenehana proprietary. Manaʻo ʻo Vectis IP e hoʻololi i ke kūlana laikini patent o kēia codec a ua hoʻomaka ʻo ia e ʻae i nā noi mai nā ʻoihana e paʻa ana i nā patent e pili ana me nā ʻenehana Opus.
Ma hope o ka hoʻokumu ʻia ʻana o ka wai patent, hoʻolālā lākou e kālele i ka hōʻiliʻili aliʻi ma luna o nā mea hana o nā lako lako e kākoʻo ana iā Opus. ʻAʻole pili ka laikini i nā hoʻokō codec wehe, nā noi, nā lawelawe a me ka hāʻawi ʻana i nā ʻike. ʻO Fraunhofer lāua ʻo Dolby ka poʻe patent mua i hui pū me ia. Manaʻo ʻia i loko o nā mahina e hiki mai ana e hoʻokumu ʻia kahi wai ʻoi aku ma mua o hoʻokahi haneli mau patent a e kono ʻia nā mea hana e laikini i ka hoʻohana ʻana i ka codec Opus i kā lākou mau polokalamu. ʻO ka nui o ke aliʻi he 15-12 eurocents mai kēlā me kēia hāmeʻa.
Hoʻomaopopo ʻia ʻo ka hoʻohui ʻana i ka format Opus, Vectis IP e hana like ana i ka hoʻokumu ʻana i nā loko patent e uhi ana i nā ʻenehana ʻē aʻe e pili ana i ke kiʻi a me ka wikiō coding, kamaʻilio, e-commerce a me nā pūnaewele kamepiula.
Hoʻokumu ʻia ka codec Opus ma ka hoʻohui ʻana i nā ʻenehana maikaʻi loa mai ka codec CELT i hoʻomohala ʻia e Xiph.org a me ka codec SILK i wehe ʻia e Skype. Ma waho aʻe o Skype a me Xiph.Org, ua komo pū nā hui e like me Mozilla, Octasic, Broadcom a me Google i ka hoʻomohala ʻana o Opus. Hōʻike ʻo Opus i ka maikaʻi hoʻopāpā kiʻekiʻe a me ka latency haʻahaʻa no nā leo hoʻoheheʻe kiʻekiʻe-bitrate a me ka hoʻoemi leo i nā noi kelepona VoIP i kāohi ʻia i ka bandwidth. Ma mua, ua ʻike ʻia ʻo Opus ʻo ia ka codec maikaʻi loa i ka wā e hoʻohana ai i kahi bitrate 64Kbit (ua lanakila ʻo Opus i nā mea hoʻokūkū e like me Apple HE-AAC, Nero HE-AAC, Vorbis a me AAC LC). Ua laikini ʻia nā hoʻokō kuhikuhi o ka Opus encoder a me ka decoder ma lalo o ka laikini BSD. Loaʻa i ka lehulehu nā kikoʻī piha piha, manuahi, a ʻae ʻia ma ke ʻano he maʻamau pūnaewele.
Hāʻawi ʻia nā patent a pau i hoʻohana ʻia ma Opus e nā hui i komo no ka hoʻohana ʻole ʻia me ka uku ʻole ʻia o nā aliʻi - hāʻawi ʻia nā patent i nā noi a me nā huahana e hoʻohana ana iā Opus, me ka ʻole o ka ʻae ʻia. ʻAʻohe palena i ka laulā o ka noi a me ka hana ʻana i nā hoʻokō ʻokoʻa ʻē aʻe. Eia naʻe, ua hoʻopau ʻia nā kuleana āpau i hāʻawi ʻia i ka wā o ka hoʻopiʻi patent e pili ana i ka ʻenehana Opus e kūʻē i kekahi mea hoʻohana iā Opus. Hana ʻia ka hana a Vectis IP i ka loaʻa ʻana o nā patent e pili pū ana me Opus, akā ʻaʻole nona nā ʻoihana i komo mua i kāna hoʻomohala ʻana, hoʻohālikelike a hoʻolaha.
