Rigimar HDMI 2.1 DP 2.0 darussan da aka koya: Ana buƙatar takaddun igiyoyi.

Ka tuna da jayayyar kwanan nan game da ma'aunin HDMI 2.1?HDMI 2.1 ko dai gaskiya ne ko ƙarya saboda rashin fahimtar aikin jami'an HDMI, rikitar da fahimtar mabukaci.An yi sa'a, VESA ta koyi darasi a wannan karon kuma dole ne ta ba da takaddun shaida tare da yiwa lakabin igiyoyin DP 2.0, ta yadda za a sami nau'ikan nau'ikan igiyoyi daban-daban.An sanar da ma'auni na DP 2.0 a baya a cikin 2019. Sabon ma'aunin yana haɓaka bandwidth na ka'idar zuwa 80Gbps kuma yana amfani da sabon tsarin ɓoyewa, 128/132b, wanda ke ƙaruwa da inganci zuwa 97%.

Ainihin samuwa har zuwa 77.4Gbps, daidai da cikakken sau uku DP 1.3 / 1.4, fiye da bandwidth na ka'idar HDMI 2.1 48Gbps.

Duk da haka, dangane da layin bayanai, DP 2.0 yana da hanyoyi daban-daban guda uku.An saita bandwidth na kowane tashar a 10Gbps, 13.5Gbps da 20Gbps, wanda VESA ke kira "UHBR/Ultra High Bit Rate".Ana kiran su UHBR 10, UHBR 13.5 da UHBR 20 bisa ga bandwidth.

Asalin bandwidth na UHBR 10 shine 40Gbps, kuma ingantaccen bandwidth shine 38.69Gbps.Wayar jan ƙarfe mai wucewa ta isa.Aikin ba da takardar shedar waya ta DP 8K da ya gabata a zahiri ya haɗa da shi, wato DP data waya da ta wuce satifiket ɗin 8K ya cika buƙatun amincin siginar UHBR 10.

UHBR 13.5, UHBR 20 ya bambanta, asalin bandwidth 54Gbps, 80Gbps, ingantaccen bandwidth 52.22Gbps, 77.37Gbps, waya mai wucewa kawai za'a iya amfani dashi don watsawa ta ɗan gajeren nisa, kamar tashar fadada kwamfutar tafi-da-gidanka, yana buƙatar waya mai aiki, wato, dasa. tare da madaidaicin iko da guntu ƙarawa.

Saboda wannan ma'auni, DP 2.0 igiyoyi sun bambanta a zahiri, kuma VESA a ƙarshe ta yanke shawarar ba da takaddun igiyoyi daban-daban don a iya bambanta su.
