Emhlabeni wethelevishini yekhebula (CATV), ukuqinisekisa ukusebenza kahle nekhwalithi yesiginali kubalulekile ekunikezeni amakhasimende ithuba lokubuka elingenazihibe.Izandiso zolayini be-CATV zidlala indima ebalulekile ekwandiseni ukusebenza kwesistimu kamabonakude wekhebula ngokwandisa ububanzi besiginali nokuthuthukisa ikhwalithi yesiginali iyonke.Kulesi sihloko, sizohlola izinzuzo zezandiso zomugqa we-CATV nokuthi zingasiza kanjani ukukhulisa ukusebenza kwe-CATV.
Izandiso zomugqa we-CATVziyizingxenye ezibalulekile ezinhlelweni zekhebula le-TV, ikakhulukazi uma amasignali kudingeka adluliselwe amabanga amade noma ezindaweni ezinokulahlekelwa okukhulu kwesignali.Lawa madivayisi asebenza ngokukhulisa isignali nokunxephezela nganoma yikuphi ukulahlekelwa okungenzeka ngenkathi isignali isakazwa ngenethiwekhi enezintambo.Ngokuthuthukisa amandla esignali, izandisi zolayini ziqinisekisa ukuthi isignali ifinyelela lapho iya khona ngokuncishiswa okuncane, ihlinzeka ngesithombe esingcono nekhwalithi yomsindo kumsebenzisi wokugcina.
Enye yezinzuzo eziyinhloko zokusebenzisa i-CATV line extender yikhono lokunweba ukumbozwa kwesiginali ye-TV yakho yekhebula.Lokhu kunenzuzo ikakhulukazi kumanethiwekhi amakhulu anezintambo adinga ukusabalalisa amasignali endaweni ebanzi yejografi.Ngokubeka ngobuchule izandisi zemigqa ezindaweni zamasu eduze kwenethiwekhi, abaqhubi bezintambo banganweba ngempumelelo ukumbozwa kwamasignali abo, baqinisekise ukuthi ngisho nabasebenzisi abakude kakhulu bathola isignali eqinile necacile.
Ukwengeza, izandiso zolayini be-CATV zidlala indima ebalulekile ekunqobeni ukulahlekelwa kwesignali kanye nokuhlanekezelwa okubangelwa izici ezifana nokuncishiswa kwekhebula, ukungahambi kahle kokuphazamiseka, kanye nokuphazamiseka kwemvelo.Lezi zinkinga zinganciphisa kakhulu ikhwalithi yesignali, okuholela kukhwalithi yesithombe ephansi nokulahlekelwa kwesignali.Izandiso zolayini zisiza ekudambiseni lezi zinkinga ngokukhulisa isignali nokunxephezela noma yikuphi ukulahlekelwa, okuholela ekudlulisweni kwesignali okuqinile nokuthembekile.
Enye inzuzo yokusebenzisa izandisi zomugqa we-CATV amandla azo okusekela ukudluliswa kwencazelo ephezulu (HD) nokuqukethwe kwencazelo ephezulu kakhulu (UHD).Njengoba isidingo sokuqukethwe kwevidiyo yekhwalithi ephezulu siqhubeka sikhula, abaqhubi bezintambo bangaphansi kwengcindezi yokuletha ikhwalithi yesithombe ephezulu kwababhalisile.Izandisi zolayini zidlala indima ebalulekile ekuqinisekiseni ukuthi amasiginali we-HD ne-UHD adluliselwa ngokwethembeka okuphezulu, okuvumela abasebenzisi ukuthi bajabulele ukubuka okugxilile ngempela.
Ukwengeza, izandiso zolayini zifaka isandla ekuthembekeni kukonke nasekuzinzeni kohlelo lwakho lwekhebula le-TV.Ngokugcina ubuqotho besignali nokunxephezela ukulahlekelwa kwesignali, izandiso zolayini zisiza ukunciphisa ukuphazamiseka kwesevisi futhi ziqinisekise ukusebenza okungaguquki kuyo yonke inethiwekhi.Lokhu kubaluleke kakhulu ezindaweni ezivamise ukucekelwa phansi kwezimpawu, njengezindawo ezikude noma zasemakhaya, lapho ukusebenzisa izandiso zolayini kungathuthukisa kakhulu ukwethembeka kukonke kwesevisi yakho yekhebula le-TV.
Sekukonke,Izandiso zomugqa we-CATVayithuluzi elibalulekile lokukhulisa ukusebenza kwesistimu yakho yekhebula le-TV.Izandisi zomugqa zidlala indima ebalulekile ekuqinisekiseni ukuthi ababhalisile bathola ukuzizwisa kokubukwa okuphezulu ngokunweba ukumbozwa kwesignali, ukunxephezela ukulahleka kwamasignali, nokusekela ukulethwa kokuqukethwe kwekhwalithi ephezulu.Njengoba isidingo sokuqukethwe kwevidiyo yekhwalithi ephezulu siqhubeka sikhula, ukubaluleka kwezandiso zomugqa ekugcineni ukusebenza kahle kwe-CATV akunakugcizelelwa.Abaqhubi bekhebula abafuna ukuthuthukisa ikhwalithi nokuthembeka kwesevisi yabo yekhebula kufanele bacabangele ukuphakelwa kwamasu okunwetshwa kolayini njengotshalomali olubalulekile ekwandiseni ukusebenza kwekhebula.
