I-HDMI2.1 iteknoloji yokutolika iteknoloji

I-HDMI 2.1 ikhonkco ibone ukuhlaziywa okuninzi kwiiparamitha zokusebenza zombane kunye nomzimba xa kuthelekiswa ne-HDMI 1.4 version. Makhe sijonge kuhlaziyo ngalunye:

1, Ukonyuka koVavanyo oluPhakamileyo lwe-HDMI iziqhagamshelo:

Njengoko imfuno yokudluliselwa kwedatha ephezulu, ngakumbi i-4K kunye ne-8K Ultra HD (UHD) yeTV, iphakama, i-HDMI iba yinto ebalulekileyo yokudluliselwa kwedatha ethembekileyo phakathi komthombo (umdlali wevidiyo) kunye nommkeli (i-TV). Ngamazinga aphezulu edatha, uqhagamshelwano phakathi kwezi zixhobo luba ngumqobo wokuhanjiswa kwedatha ethembekileyo. Olu nxibelelwano lunokukhokelela kwimiba yeSimo soMphawu (SI) esifana ne-Electromagnetic Interference (EMI), i-crosstalk, i-Inter-Symbol Interference (ISI), kunye ne-signal jitter. Ngenxa yoko, ngokunyuka kwamazinga edatha, i-HDMI 2.1 idizayini yokudibanisa iqalile ukuqwalasela i-SI. Ngenxa yoko, uvavanyo lombutho longeze iimfuno zovavanyo lwe-high-frequency test. Ukuphucula ukusebenza kwe-SI ye-HDMI izixhumi, abavelisi bezonxibelelwano baye baguqula iimilo zezikhonkwane zetsimbi kunye nezixhobo ze-dielectric ngokwemigaqo yoyilo kunye nokuthembeka koomatshini ukuhlangabezana neemfuno zovavanyo oluphezulu.

2 、 IiMfuno eziNyusekileyo zobubanzi be-HDMI 2.1 Iziqhagamshelo:

I-HDMI yangaphambili ye-2.0 yayine-throughput ye-18Gbps kodwa ayizange ichaze iintambo ze-HDMI ezintsha okanye izixhumi. I-HDMI 2.1, ngakolunye uhlangothi, iqhayisa ngokuphindwe kabini i-throughput, ivumela i-bandwidths ukuya kwi-48 Gbps. Ngelixa iintambo ezintsha ze-HDMI ze-2.1 ziya kubuyela ngasemva zihambelana ne-HDMI 1.4 kunye ne-HDMI izixhobo ze-2.0, iintambo ezindala aziyi kuhambela phambili-zihambelana neenkcukacha ezintsha. I-HDMI 2.1 izixhumi zibonakalisa iziteshi ezine zedatha: i-D2, i-D1, i-D0, kunye ne-CK, apho idatha ihanjiswa ngokwahlukileyo. Njengoko umjelo ngamnye wabelana ngeempawu zombane ezifanayo, i-HDMI 2.1 idizayini yokudibanisa kufuneka ibonise ukusebenza okuphezulu kwe-SI ukuhlangabezana ne-48Gbps bandwidth yesizukulwana esilandelayo se-HDMI isixhumi.

3, IiMfuno ezongezelelweyo eziMahluko:

Uvavanyo lwe-HDMI 2.1 lokudibanisa luwela phantsi kweCandelo 3, ngelixa uvavanyo lwe-HDMI 1.4 luwela phantsi kweCandelo 1 kunye neCandelo 2. Emva kwe-HDMI 2.1, iimilo zokudibanisa zikhawulelwe kwi-Type A, C, kunye ne-D, kunye ne-interface ye-E esetyenziswa ngaphambili ngokuyinhloko kwi-automotive. ibala liyapheliswa. Ukuphucula iimpawu zombane ukuhlangabezana nemigangatho ye-HDMI 2.1, idizayini yokudibanisa ifuna ukuguqulwa ukuyila iiparitha ezifana nobubanzi, ubukhulu, kunye nobude bezikhonkwane zetsimbi. Abanye abavelisi banokusebenzisa ezinye iindlela, ezinjengokungenisa izikhewu kwisixhobo sombane sesokethi, ukunciphisa ukudityaniswa kwecapacitance. Ekugqibeleni, iiparamitha zoyilo eziqinisekisiweyo kufuneka zihlangabezane noluhlu lwe-impedance. I-HDMI izixhumi ze-2.1 zibonelela ngokusebenza okungcono kwe-SI kuneenguqulelo zangaphambili ezisezantsi, kunye nabavelisi abanxibelelanayo abahambelanayo baya kusebenzisa izixhobo ezahlukeneyo kunye nolawulo lwenkqubo.
