Nā haʻawina HDMI 2.1 hoʻopaʻapaʻa DP 2.0: Pono e hōʻoia ʻia nā kelepona.

E hoʻomanaʻo i ka hoʻopaʻapaʻa hou e pili ana i ka maʻamau HDMI 2.1?He ʻoiaʻiʻo a he wahaheʻe paha ʻo HDMI 2.1 ma muli o ka hana hiki ʻole ke hoʻomaopopo ʻia e nā luna HDMI, huikau i ka manaʻo o nā mea kūʻai aku.ʻO ka mea pōmaikaʻi, ua aʻo ʻo VESA i kāna haʻawina i kēia manawa a pono e hōʻoia a hoʻopaʻa inoa i nā kaula DP 2.0, i hiki ke loaʻa maʻalahi nā kumukūʻai o nā kaula.Ua hoʻolaha hou ʻia ka maʻamau DP 2.0 ma 2019. Hoʻonui ka maʻamau hou i ka bandwidth theoretical i 80Gbps a hoʻohana i kahi mīkini hoʻopili hou, 128/132b, e hoʻonui ai i ka pono i 97%.

ʻO ka loaʻa maoli a hiki i 77.4Gbps, e like me ka piha ʻekolu manawa DP 1.3/1.4, ʻoi aku ka nui ma mua o ka bandwidth theoretical o HDMI 2.1 48Gbps.

Eia nō naʻe, ma ke ʻano o nā laina ʻikepili, ʻekolu mau ʻano hana like ʻole ka DP 2.0.Hoʻonohonoho ʻia ka bandwidth o kēlā me kēia kahawai ma 10Gbps, 13.5Gbps a me 20Gbps, ka mea i kapa ʻia e VESA "UHBR/Ultra High Bit Rate".Kapa ʻia lākou ʻo UHBR 10, UHBR 13.5 a me UHBR 20 e like me ka bandwidth.

ʻO ka bandwidth kumu o UHBR 10 he 40Gbps, a ʻo ka bandwidth kūpono ʻo 38.69Gbps.Ua lawa ka uwea keleawe pasif.ʻO ka papahana hōʻoia uea DP 8K ma mua, ʻo ia hoʻi, ʻo ka uea data DP i hala i ka palapala hōʻoia 8K e hoʻokō i nā koi pono hōʻailona o UHBR 10.

ʻOkoʻa ka UHBR 13.5, UHBR 20, ʻo ka bandwidth kumu 54Gbps, 80Gbps, bandwidth kūpono 52.22Gbps, 77.37Gbps, hiki ke hoʻohana ʻia ka uea passive no ka hoʻouna ʻana i kahi mamao loa, e like me ka hoʻonui ʻia ʻana o ka pona, pono ka uea ikaika, ʻo ia hoʻi, hoʻokomo ʻia. me ka mana like a me ka chip amplification.

Ma muli o kēia maʻamau, ʻokoʻa maoli nā kaula DP 2.0, a ua hoʻoholo hope ʻo VESA e hōʻoia i nā kaula like ʻole i hiki ke hoʻokaʻawale ʻia.

ʻO ke kikoʻī, hele mai nā kaula DP 2.0 i ʻelua mau kūlana ma muli o ka wikiwiki.Kākoʻo nā kaula DP40 i ka maʻamau UHBR10 o 10Gbps i kēlā me kēia kanal i kēlā me kēia o nā kaha kūloko ʻehā, no ka holo holoʻokoʻa o 40Gbps.

ʻO nā uwea i kapa ʻia ʻo DP80 he UHR20 20Gbps no kēlā me kēia kahawai me ka wikiwiki a hiki i 80Gbps.

DP40, DP80 kelepona no laila aia kahi ʻokoʻa ʻokoʻa, ʻaʻole maʻalahi e huikau, makemake nā mea hana e lawaiʻa i nā wai pilikia ʻaʻole hiki, he mea maikaʻi loa kēia.

Ua hōʻike ʻo VESA ua hoʻomaka nā laina DP maʻamau DP40 a me DP80 a me nā laina MINI DP i ka hana ʻana, a ʻo ka pūʻulu mua o nā hōʻike a me nā mea hana ʻē aʻe i hala i ka palapala hōʻoia.
