Ingcaciso yetekhnoloji yesixhumi se-HDMI2.1

I I-Hdmi 2.1 Isixhumi sibone uhlaziyo oluninzi kwiiparameter zokusebenza kombane kunye nokusebenza komzimba xa kuthelekiswa nohlobo lwe-HDMI 1.4. Makhe sijonge nganye kwezi hlaziyo:

1. Uvavanyo oluQhelekileyo oluQhelekileyo lwe- Isinxibelelanisi seHdmis:

Njengoko imfuno yokudluliselwa kwedatha ngesantya esiphezulu, ingakumbi kwiiTV ze-4K kunye ne-8K Ultra HD (UHD), iyanda, i-HDMI iba yinto ebalulekileyo ekudlulisweni kwedatha okuthembekileyo phakathi komthombo (isidlali sevidiyo) kunye nesamkeli (iTV). Ngamazinga aphezulu edatha, ukunxibelelana phakathi kwezi zixhobo kuba yingxaki yokudluliselwa kwedatha okuthembekileyo. Olu nxibelelwano lunokukhokelela kwimiba yeSignal Integrity (SI) efana ne-Electromagnetic Interference (EMI), i-crosstalk, i-Inter-Symbol Interference (ISI), kunye ne-signal jitter. Ngenxa yoko, ngokunyuka kwamazinga edatha, uyilo lwe-HDMI 2.1 connector luqalile ukuqwalasela i-SI. Ngenxa yoko, uvavanyo lomanyano longeze iimfuno zovavanyo oluphezulu. Ukuphucula ukusebenza kwe-SI kwezixhumi ze-HDMI, abavelisi bezixhumi batshintshe iimilo zeepini zesinyithi kunye nezixhobo ze-dielectric ngokwemigaqo yoyilo kunye nokuthembeka koomatshini ukuhlangabezana neemfuno zovavanyo oluphezulu.

2. Iimfuno zeBandwidth ezongeziweyo zeHDMI 2.1 Connectors:

I-HDMI 2.0 yangaphambili yayine-output ye-18Gbps kodwa ayizange ichaze entsha Intambo ye-Hdmis okanye izihlanganisi. I-HDMI 2.1, kwelinye icala, iqhayisa ngokuphindwe kabini komthamo, ivumela ii-bandwidths ezifikelela kwi-48 Gbps. Ngelixa iintambo ezintsha ze-HDMI 2.1 ziya kuhambelana ngasemva nezixhobo ze-HDMI 1.4 kunye ne-HDMI 2.0, iintambo ezindala aziyi kuhambelana phambili neenkcukacha ezintsha. Izihlanganisi ze-HDMI 2.1 zineendlela ezine zedatha: i-D2, i-D1, i-D0, kunye ne-CK, apho idatha idluliselwa khona ngokwahlukileyo. Njengoko itshaneli nganye ineempawu zombane ezifanayo, uyilo lwezihlanganisi ze-HDMI 2.1 kufuneka lubonise ukusebenza okuphezulu kwe-SI ukuze luhlangabezane ne-bandwidth ye-48Gbps yesihlanganisi se-HDMI sesizukulwana esilandelayo.

3, Iimfuno ezongezelelweyo zokwahluka:

Uvavanyo lwe-HDMI 2.1 connector luphantsi koDidi 3, ngelixa uvavanyo lwe-HDMI 1.4 luphantsi koDidi 1 kunye noDidi 2. Emva kwe-HDMI 2.1, iimilo ze-connector zikhawulelwe kuDidi A, C, kunye no-D, kunye ne-interface yohlobo E eyayisetyenziswa ngaphambili ikakhulu kwicandelo leemoto ikhutshwa kancinci. Ukuphucula iimpawu zombane ukuze kuhlangatyezwane nemigangatho ye-HDMI 2.1, uyilo lwe-connector lufuna utshintsho kuyilo lwee-parameter ezifana nobubanzi, ubukhulu, kunye nobude bee-pin zesinyithi. Abanye abavelisi banokusebenzisa ezinye iindlela, ezinje ngokufaka izithuba kwizinto ze-dielectric zesokethi, ukunciphisa i-capacitance coupling. Ekugqibeleni, ii-parameter zoyilo eziqinisekisiweyo kufuneka zihlangabezane nobubanzi be-impedance. Izihlanganisi ze-HDMI 2.1 zibonelela ngokusebenza okungcono kwe-SI kuneenguqulelo zangaphambili ezisezantsi, kwaye abavelisi be-connector abahambelanayo baya kusebenzisa ulawulo lwezixhobo kunye neenkqubo ezahlukeneyo.
