Ukuchazwa kobuchwepheshe besixhumi se-HDMI2.1

I I-Hdmi 2.1 I-connector ibone izibuyekezo eziningi kumapharamitha okusebenza kagesi nawomzimba uma kuqhathaniswa nenguqulo ye-HDMI 1.4. Ake sihlole ngayinye yalezi zibuyekezo:

1. Ukuhlolwa Okukhulu Kwemvamisa Ephakeme kwe- Isixhumi se-Hdmis:

Njengoba isidingo sokudluliselwa kwesilinganiso sedatha ephezulu, ikakhulukazi kuma-TV e-4K kanye ne-8K Ultra HD (UHD), sikhuphuka, i-HDMI iba yinto ebalulekile ekudlulisweni kwedatha okuthembekile phakathi komthombo (isidlali sevidiyo) kanye nesamukeli (i-TV). Ngamazinga aphezulu edatha, ukuxhumana phakathi kwala madivayisi kuba yisithiyo sokudluliselwa kwedatha okuthembekile. Lokhu kuxhumana kungaholela ezinkingeni ze-Signal Integrity (SI) ezifana ne-Electromagnetic Interference (EMI), i-crosstalk, i-Inter-Symbol Interference (ISI), kanye ne-signal jitter. Ngenxa yalokho, ngokukhuphuka kwamazinga edatha, ukwakheka kwesixhumi se-HDMI 2.1 sekuqalile ukucabangela i-SI. Ngenxa yalokho, ukuhlolwa kokuhlangana kungeze izidingo zokuhlolwa kwemvamisa ephezulu. Ukuze kuthuthukiswe ukusebenza kwe-SI kwezixhumi ze-HDMI, abakhiqizi bezixhumi bashintshe izimo zezikhonkwane zensimbi nezinto zokwakha i-dielectric ngokwemithetho yokuklama kanye nokuthembeka kwemishini ukuze kuhlangatshezwane nezidingo zokuhlolwa kwemvamisa ephezulu.

2. Izidingo Ezikhulisiwe Ze-Bandwidth Zezixhumi ze-HDMI 2.1:

I-HDMI 2.0 yangaphambilini yayine-output engu-18Gbps kodwa ayizange ichaze entsha Ikhebula le-Hdmis noma izixhumi. I-HDMI 2.1, ngakolunye uhlangothi, izigqaja ngokuphindwe kabili komthamo, okuvumela ama-bandwidth afinyelela ku-48 Gbps. Ngenkathi izintambo ezintsha ze-HDMI 2.1 zizohambisana emuva namadivayisi e-HDMI 1.4 kanye ne-HDMI 2.0, izintambo ezindala ngeke zihambisane nezincazelo ezintsha. Izixhumi ze-HDMI 2.1 zineziteshi ezine zedatha: i-D2, i-D1, i-D0, kanye ne-CK, lapho idatha idluliselwa khona ngokuhlukile. Njengoba isiteshi ngasinye sabelana ngezici ezifanayo zikagesi, imiklamo yezixhumi ze-HDMI 2.1 idinga ukubonisa ukusebenza okuphezulu kwe-SI ukuze ihlangabezane ne-bandwidth engu-48Gbps yesixhumi se-HDMI sesizukulwane esilandelayo.

3, Izidingo Ezengeziwe Zokwehluka:

Ukuhlolwa kwesixhumi se-HDMI 2.1 kuwela ngaphansi kweSigaba 3, kanti ukuhlolwa kwe-HDMI 1.4 kuwela ngaphansi kweSigaba 1 kanye neSigaba 2. Ngemuva kwe-HDMI 2.1, izimo zesixhumi zikhawulelwe ku-Type A, C, kanye no-D, kanti isixhumi esibonakalayo sohlobo E esisetshenziswe ngaphambilini ikakhulukazi emkhakheni wezimoto siyasuswa. Ukuze kuthuthukiswe izici zikagesi ukuze kuhlangatshezwane nezindinganiso ze-HDMI 2.1, imiklamo yesixhumi idinga ukuguqulwa kokuklama amapharamitha afana nobubanzi, ukujiya, kanye nobude bezikhonkwane zensimbi. Abanye abakhiqizi bangasebenzisa nezinye izindlela, njengokufaka izikhala ezintweni ze-dielectric zesokhethi, ukunciphisa ukuhlanganiswa kwe-capacitance. Ekugcineni, amapharamitha okuklama aqinisekisiwe adinga ukuhlangabezana nobubanzi be-impedance. Izixhumi ze-HDMI 2.1 zinikeza ukusebenza okungcono kwe-SI kunezinguqulo zangaphambilini ze-lower-tier, futhi abakhiqizi besixhumi abahambisanayo bazosebenzisa izilawuli ezahlukene zamadivayisi nezinqubo.
