I-CATV yikota elifutshane leenkonzo zethelevishini yekhebula. Isiseko esisisiseko sekhabhi esisekela i-TV ye-cable nayo isekela intanethi ye-intanethi. Abanikezeli benkonzo ye-intanethi (ISPs) banikezela abathengi babo ngentambo ye-intanethi kunye kunye nomabonwakude kwii-CATV ezifanayo.
Izibonelelo zeCATV
Abanikezeli beekhefri baqhuba ngokuthe ngqo okanye baqeshise amandla okuxhunywa kwenethiwekhi ukuxhasa abo bathengi. I-Traffic CATV isebenza ngokugqithiseleyo kwiimbambo ze-fiber optic ekupheleni komnikezeli kunye nangaphezulu kwezixhobo ze-coaxial ekupheleni komthengi.
DOCSIS
Uninzi lweenethiwekhi zentambo zixhasa iinkcukacha zeNgcaciso yeNkonzo yeCandelo leNkcukacha zeCandelo (iDOCSIS) . I-DOCSIS ichaza indlela idijithali yokubonakalisa ngayo imigca yeCATV isebenza. I-original DOCSIS 1,0 yamkelwe ngo-1997 kwaye iqhutywe ngokuphuculwa kwimizuzu:
- I-DOCSIS 1.1 (1999) - yongezwa ngeNqanaba leNkonzo (QoS) oluyimfuneko ukuxhasa izwi nge-IP (VoIP)
- I-DOCSIS 2.0 (2001) - ukunyuka kweedata zedatha ehamba phambili
- I-DOCSIS 3.0 (2006) - ukunyuka kwamaxabiso e-data kunye ne- IPv6 inkxaso
- I-DOCSIS 3.1 (2013+) - inyuke kakhulu inani leedatha
Ukufumana isicwangciso esipheleleyo somsebenzi kunye nokusebenza okuphezulu kwiinkcukacha zekhompyutha kwi-intanethi, abathengi kufuneka basebenzise i-modem exhasa i-version efanayo okanye ephakamileyo ye-DOCSIS inethiwekhi yomncedisi wabo wesevisi.
Iinkonzo zeeNtanethi zeNtambo
Abathengi be-intanethi ye-Intanethi kufuneka bafake imodem yekhebula (ngokuqhelekileyo, i modem ye-DOCSIS) ukukhawulela i- router yabo yasekhaya okanye ezinye izixhobo kwiinkonzo ze-Intanethi. Amanethiwekhi asekhaya angasebenzisa kwakhona iifowuni zendlela yokusebenzisa ikhefu ezidibanisa ukusebenza kweemodem yekhebula kunye nomzila wendlela ebanzi kwiqhobo enye.
Abaxhasi kufuneka babhalisele kwisicwangciso senkonzo ukuze bafumane i-intanethi ye-intanethi. Abanikezeli abaninzi banikela ngokukhetha ezininzi izicwangciso ukusuka ekupheleni okude ukuya ekupheleni. Imiba ephambili ibandakanya:
- Izicwangciso ezidibanisa i-intanethi ye-Intanethi, ithelevishini ye-cable kunye nesezinye iinkonzo iinkonzo zeefowuni zibizwa ngokuba yiipakethe. Okuthiwa "ukudlala kathathu" iipakethi ziquka zonke ezintathu. Nangona iindleko zamaphakheji ezithandwayo zidlula inkonzo ye-Intanethi yedwa, abanye abathengi bagcina imali ngokugcina imirhumo yabo kunye nomboneleli omnye.
- Ezinye iinkonzo ze-intanethi zendawo zibeka imida emininzi kwimali enokuthi yenziwe ngexesha lokuhlawula (ngokuqhelekileyo, ngenyanga) ngelixa abanye banikela ngemininingwane engenamkhawulo.
- Iimodem zeekhamera ziqhele ukuba ziqeshwe ngemali eyongezelelweyo kunokuthengwa ngokwahlukileyo
Abaxhasi beCATV
Ukubambisa ithelevishini kwisevisi yekhebula, intambo ye coaxial kufuneka ifakwe kwi-TV. Uhlobo olufanayo lwekhebula lusetyenziselwa ukudibanisa imodem yekhebula kwinkonzo yekhebula. Ezi zixhobo zisebenzisa i-standard standard "F" yesikhombisi esivame ukubizwa ngokuba ngumxhamli weCATV, nangona ezi zixhunywa ezifanayo eziqhelekileyo ezisetyenziselwa iisetups ze-analog kumashumi ambalwa eminyaka edlulileyo ngaphambi kokuba i-TV yekhebula ikhona.
CATV kunye neCAT5
Ngaphandle kwegama elifanayo, i-CATV ayinxulumene neCandelo 5 (CAT5) okanye ezinye iintlobo zetambo zenethiwekhi zendabuko. I-CATV ibuye ibhekisele kwintlobo eyahlukeneyo yeenkonzo zikamabonwakude kune- IPTV .
