Emhlabeni we-cable TV,Izandiso zomugqa we-CATVidlala indima ebalulekile ekwandiseni ukukhava kanye nokuthuthukisa ukwethembeka. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo sekhwalithi ephezulu, izinsizakalo zethelevishini ezingaphazamiseki ziyaqhubeka nokwanda. Lokhu kuye kwaholela ekuthuthukisweni kwezixazululo ezintsha, njengezandiso zolayini we-cable TV, osekuphenduke ingxenye ebalulekile yokusabalalisa amasignali e-cable TV.
I-CATV line extender iyithuluzi eliklanyelwe ukukhulisa nokwelula ukumbozwa kwamasignali wekhebula le-TV, ukuqinisekisa ukuthi abasebenzisi bathola ukwamukelwa okucacile nokungaguquguquki endaweni ebanzi. Lokhu kubaluleke kakhulu ezindaweni ezinesimo sezwe esinzima noma amabanga amade phakathi kwesihloko sekhebula nomsebenzisi wokugcina. Ngokuthuthukisa amandla esignali, izandisi zolayini zinqoba ngempumelelo isignali, ukuqinisekisa ukuthi abasebenzisi bathola uhla olugcwele lweziteshi namasevisi ngaphandle kokuphazamiseka.
Enye yezinzuzo eziyinhloko zezandiso zolayini be-CATV yikhono lokwelula ukutholakala ezindaweni ebezinganakekelwa kahle ngaphambilini noma ezinekhwalithi yesignali ephansi. Lokhu kubaluleke kakhulu ezindaweni zasemaphandleni noma ezikude lapho ingqalasizinda yokusabalalisa ithelevishini yezintambo ingase ibe nomkhawulo. Ngokubeka ngobuchule izandisi zolayini kumanethiwekhi anezintambo, abahlinzeki besevisi banganweba ukufinyelela kwabo futhi bafinyelele isisekelo samakhasimende esikhulu, ngaleyo ndlela bakhulise ukungena kwemakethe namandla abo emali engenayo.
Ngokungeziwe ekwandiseni ukusabalala, izandiso zolayini wekhebula le-TV zidlala indima ebalulekile ekuthuthukiseni ukwethembeka kwesevisi yakho ye-TV yekhebula. Ukuncishiswa kwesignali nokuphazamiseka kungenzeka ngenxa yezinto ezihlukahlukene ezihlanganisa ibanga, ukungafani kokuphazamiseka, nezimo zemvelo. Izandisi zolayini zixazulula lezi zinkinga ngokukhulisa isignali nokunxephezela noma yikuphi ukulahlekelwa, okuholela ekudluliselweni kwesignali okuqinile nokuzinza. Lokhu kuthuthukisa ikhwalithi yesevisi nokwaneliseka kwamakhasimende njengoba ababhalisile bengajabulela okuhlangenwe nakho kokubuka ngaphandle kokuphazamiseka kwesignali.
Ngaphezu kwalokho, ukuthunyelwa kwezandiso zolayini be-CATV kusiza futhi ukuthuthukisa ukusebenza kahle okuphelele kwenethiwekhi ye-cable TV. Ngokuthuthukisa amandla esignali nekhwalithi, abahlinzeki besevisi banganciphisa isidingo sokuthuthukiswa kwengqalasizinda ebizayo noma ukufakwa kwamanodi okusabalalisa engeziwe. Lokhu akunciphisi kuphela izindleko zokusebenza, kodwa futhi kwenza ukunakekelwa nokuphathwa kwenethiwekhi kube lula, okuholela engqalasizinda yamakhebula engabizi kakhulu futhi esimeme.
Njengoba isidingo sokuchazwa okuphezulu (HD) kanye nokuqukethwe kwe-ultra-high definition (UHD) siqhubeka sikhula, indima yezandiso zomugqa we-CATV iba ebaluleke nakakhulu. Lawa madivayisi abalulekile ekuqinisekiseni ukuthi amasiginali adinga umkhawulokudonsa odinga ukuletha i-HD nokuqukethwe kwe-Ultra HD alethwa ngempumelelo nangokuthembekile ezindlini zabasebenzisi. Ngaphandle kwezandiso zolayini ukuze kuhlinzekwe ukukhulisa kahle nesimo samasignali, ukulethwa kwalokhu okuqukethwe kwekhwalithi ephezulu kuba sengozini, okuholela ekubukeni okubi kwababhalisile.
Ngamafuphi,Izandiso zomugqa we-CATVziyingxenye ebalulekile yokusabalalisa isignali ye-TV yekhebula futhi zidlala indima ebalulekile ekwandiseni ukusabalala kanye nokwenza ngcono ukwethembeka. Ngokukhulisa nokubeka amasignali, izandiso zolayini zinika amandla abahlinzeki besevisi ukuthi bafinyelele izethameli ezibanzi, bathuthukise ikhwalithi yesevisi futhi bathuthukise ukusebenza kahle kwamanethiwekhi kamabonakude ekhebula. Njengoba ubuchwepheshe buqhubeka nokuvela, ukubaluleka kwezandiso zolayini be-CATV ekunikezeni isevisi ye-TV yekhebula yekhwalithi ephezulu, engaphazanyiswa kuzoqhubeka nokukhula.
