Ulwazi lweSigaba sesi-2 seMboni yezintambo ---Kungani ubukhulu (ububanzi) bezintambo ze-HDMI buthinta ukuzinza kwesignali？

Okokuqala, ukuphazamiseka kwe-electromagnetic kungenye yezinto ezibalulekile ezithinta ukuzinza kwesignali. Izintambo ezincane zisengozini enkulu yokuphazamiseka kwe-electromagnetic yangaphandle ngenxa yokuntuleka kwazo ikhono lokuvikela elanele, okuholela ekwehleni kwekhwalithi yesignali, ukushaqeka kwesithombe, ukuphambuka kombala, nezinye izinkinga. Izintambo ezijiyile zivame ukusebenzisa izinto zokuvikela ezingcono, ezinganciphisa ngempumelelo umthelela wokuphazamiseka kwangaphandle esignalini futhi zithuthukise ukuzinza kwesignali.

Okwesibili, ukuncishiswa kwesignali nakho kungenye yezinto ezibalulekile ezithinta ukuzinza kwesignali. Njengoba ubude bekhebula bukhula, isignali izobola kancane kancane ngesikhathi sokudlulisa, okuholela ekwehleni kwekhwalithi yesignali. Izintambo ezijiyile ngokuvamile zinokumelana okuphansi kanye nokusebenza okungcono kokudlulisa isignali, okunganciphisa ukuncishiswa kwesignali, kugcine ukucaca nokuqina kwesignali, futhi kusebenza kahle kakhulu ekudluliseni ibanga elide.

Ngaphezu kwalokho, izinga lokudluliswa kwedatha lingaba nomthelela ekuzinzeni kwesignali. Ngokuthandwa kwevidiyo enencazelo ephezulu, izithombe ze-3D, umsindo wekhwalithi ephezulu nokunye okuqukethwe, isidingo sesivinini sokudluliswa kwedatha naso siyakhula. Izintambo ezijiyile zinganikeza ukusebenza okungcono kokudluliswa kwesignali, zivumelane nezidingo zokudluliswa kwedatha ngesivinini esikhulu, ziqinisekise ukudluliswa kwevidiyo nomsindo kwekhwalithi ephezulu, futhi zigweme izinkinga zokulahleka kwesignali noma ukubambezeleka.

Ngakho-ke, ukukhetha ubukhulu obufanele Ikhebula le-Hdmi Kubalulekile ukuqinisekisa ukuzinza kwesignali nokuthembeka. Lapho ukhetha izintambo, ngaphezu kokucabangela ukujiya, izici ezifana nezinto zekhebula, ukusebenza kokuvikela, ubude, njll. kufanele futhi kucatshangelwe ukuhlangabezana nezidingo ezingokoqobo nokuqinisekisa ikhwalithi yokudlulisa isignali. Uma kucatshangelwa izici ezahlukahlukene, ukukhetha ikhebula le-HDMI elifanele kungathuthukisa ngempumelelo ukusebenza kwamadivayisi alalelwayo nokubukwayo futhi kulethe ulwazi olungcono lwe-audiovisual.
