GTC250 iTerestrial TV isiguquli seFrequency
Ingcaciso yeMveliso
I-GTC250 yoMguquli weTV yeTerestrial sisixhobo esilungelelanisiweyo seTV esisemhlabeni, isihluzi, isihlanganisi, isiguquli setshaneli, isilinganisi, kunye neamplifier.Ilungele ukusetyenziswa kwe-eriya edibeneyo apho imiqondiso ye-TV esemhlabeni inokukhethwa, iqhutywe, ihluzwe, idityaniswe, ilingane, kwaye ikhuliswe kanye.NgeLCD efakelweyo kunye nephedi yesitshixo, i-GTC250 ikulungele ukukhetha amajelo aphumayo kunye nokulungelelanisa imveliso yeRF.
I-GTC250 inegalelo elinye le-FM, igalelo le-VHF/UHF emine, imveliso yeRF enye kunye ne-20dB RF yovavanyo lwezibuko.Kwimiqondiso ye-DVB-T kwi-PAL-B/G, itshaneli ye-VHF ine-7MHz bandwidth kunye nejelo le-UHF line-bandwidth ye-8MHz, kungcono ukuguqulela itshaneli ye-VHF kwitshaneli ye-VHF kunye ne-UHF ukuya kwijelo le-UHF kuphela, apho i-8MHz DVB-T UHF itshaneli ukuya kwi-7MHz Ijelo le-DVB-T VHF linokuba nengxaki yokulahleka kwemixholo.
Imixholo ephambili yayo nayiphi na i-mini headend ivela kwi-satellites, i-intanethi, i-TV yomhlaba kunye neekhamera zendawo.Intloko encinci kufuneka ikhethe ividiyo efunwayo kwisathelayithi kunye ne-intanethi, mux ividiyo ekhethiweyo kwi-TS entsha.Ekubeni ii-TV ezininzi ezihlakaniphile zinokufumana izibonakaliso zedijithali ze-QAM RF ngokuthe ngqo, yenza ingqiqo ngakumbi kubaqhubi beTV yorhwebo ukuguqula i-DVB-S / S2 kwi-QAM, iguqule i-IP kwi-QAM kwaye iguqule iikhamera zendawo kwi-QAM.Ngapha koko, iTV yalapha emhlabeni isoloko ithandwa yimixholo yayo ecaleni kwababhalisi.I-QAM RF edibeneyo inokusasazwa ngokulula kwi-coaxial (okanye i-fiber) intambo kuzo naziphi na izakhiwo zokuhlala ngendlela yezoqoqosho, ukusasaza i-SD kunye ne-HD iividiyo ngaphandle kwe-STB eyongezelelweyo phambi kwe-smart TV.
