I-HDMI2.1 yokutolika kobuchwepheshe besixhumi

Isixhumi se-HDMI 2.1 sibone izibuyekezo eziningi kumapharamitha wokusebenza kagesi nokomzimba uma kuqhathaniswa nenguqulo ye-HDMI 1.4. Ake sihlole ngayinye yalezi zibuyekezo:

1, Ukuhlola Okuphakeme Okuphakeme Kwezixhumi ze-HDMI:

Njengoba isidingo sokudluliswa kwedatha ephezulu, ikakhulukazi i-4K kanye ne-8K Ultra HD (UHD) TV, sikhuphuka, i-HDMI iba yinto ebalulekile ekudluliselweni kwedatha okuthembekile phakathi komthombo (isidlali sevidiyo) nomamukeli (i-TV). Ngamazinga edatha aphezulu, ukuxhumana phakathi kwalawa madivaysi kuba ibhodlela lokudluliswa kwedatha okuthembekile. Lokhu kuxhumana kungaholela ezindabeni Zobuqotho Besiginali (SI) njenge-Electromagnetic Interference (EMI), crosstalk, Inter-Symbol Interference (ISI), kanye ne-signal jitter. Ngenxa yalokho, ngokukhuphuka kwamazinga edatha, idizayini yesixhumi se-HDMI 2.1 isiqalile ukucabangela i-SI. Ngenxa yalokho, ukuhlolwa kwenhlangano kungeze izidingo zokuhlola imvamisa ephezulu. Ukuze kuthuthukiswe ukusebenza kwe-SI kwezixhumi ze-HDMI, abakhiqizi bezixhumi balungise ukwakheka kwezikhonkwane zensimbi nezinto ze-dielectric ngokuya ngemithetho yokuklama nokwethembeka kwemishini ukuze kuhlangatshezwane nezidingo zokuhlola imvamisa ephezulu.

2、Izimfuneko Ezengeziwe Zomkhawulokudonsa wezixhumi ze-HDMI 2.1:

I-HDMI 2.0 yangaphambilini ibe nokuphuma kwe-18Gbps kodwa ayizange ichaze izintambo ezintsha ze-HDMI noma izixhumi. I-HDMI 2.1, ngakolunye uhlangothi, izidla ngaphezu kokuphindwe kabili kokuphumayo, okuvumela umkhawulokudonsa ofinyelela ku-48 Gbps. Nakuba izintambo ezintsha ze-HDMI 2.1 zizobuyela emuva zihambisane ne-HDMI 1.4 kanye namadivayisi we-HDMI 2.0, amakhebuli amadala ngeke ahambisane nokuya phambili nokucaciswa okusha. Izixhumi ze-HDMI 2.1 zifaka iziteshi ezine zedatha: i-D2, i-D1, i-D0, ne-CK, lapho idatha idluliselwa ngokuhlukile. Njengoba isiteshi ngasinye sabelana ngezici zikagesi ezifanayo, imiklamo yesixhumi se-HDMI 2.1 idinga ukukhombisa ukusebenza okuphezulu kwe-SI ukuze kuhlangatshezwane nomkhawulokudonsa ongu-48Gbps wesixhumi se-HDMI sesizukulwane esilandelayo.

3, Izidingo Ezengeziwe Ezihlukile:

Ukuhlolwa kwesixhumi se-HDMI 2.1 kungena ngaphansi kweSigaba 3, kuyilapho ukuhlola kwe-HDMI 1.4 kungena ngaphansi kweSigaba 1 neSigaba 2. Ngemva kwe-HDMI 2.1, umumo wokuxhuma ukhawulelwe ohlotsheni A, C, no-D, ngesixhumi esibonakalayo sohlobo E olwasetshenziswa ngokuyinhloko kwezezimoto. insimu iyaqedwa. Ukuze kuthuthukiswe izici zikagesi ukuze zihlangabezane namazinga we-HDMI 2.1, imiklamo yesixhumi idinga ukuguqulwa ukuze idizayine imingcele efana nobubanzi, ukujiya, nobude bezikhonkwane zensimbi. Abanye abakhiqizi bangase futhi basebenzise ezinye izindlela, njengokwethula izikhala kumpahla ye-dielectric yesokhethi, ukunciphisa ukuhlanganisa amandla. Ekugcineni, imingcele yedizayini eqinisekisiwe idinga ukuhlangabezana nobubanzi be-impedance. Izixhumi ze-HDMI 2.1 zinikeza ukusebenza okungcono kwe-SI kunezinguqulo zesigaba esiphansi sangaphambilini, futhi abakhiqizi bezixhumi abahambisanayo bazosebenzisa izilawuli ezihlukahlukene zedivayisi nezinqubo.
