Mafotokozedwe Akatundu
GWD800 ndi digito IP to QAM modulator mu 19” 1RU chassis, yopangidwa kuti ikwaniritse kufunikira kwa kachulukidwe kakang'ono, kachulukidwe kakang'ono komanso kotsika mtengo kakachitidwe ka TV kamalonda. GWD800 imakhala ndi ma module apamwamba a 3pcs SKD180X modulator, gawo lililonse la SKD180X limatulutsa zonyamula 4 za RF, zoyendetsedwa ndi gulu lakutsogolo la LCD ndi mabatani kapena doko loyang'anira maukonde. Kulowetsa kwa IP kumathandizira UPD, IGMP V2/V3 ndi TS re-muxing. GWD800 imodzi imatha kusintha zomwe zili mu IP kukhala ma siginali 12ch QAM RF. Kutulutsa kwa QAM RF kumathandizira DVB-C (J.83A/B/C), DVBT, ATSC.
Zomwe zili mumutu uliwonse wa mini zimachokera ku ma satelayiti, intaneti, TV yapadziko lapansi ndi makamera am'deralo. Mini-head iyenera kusankha kanema wofunidwa kuchokera pa satellite ndi intaneti, mux kanema wosankhidwa mu TS yatsopano. Popeza kuti ma TV ochulukirachulukira amatha kulandira ma siginecha a digito a QAM RF mwachindunji, zimapangitsa kuti ochita malonda a TV azitha kusintha DVB-S/S2 kukhala QAM, kusintha IP kukhala QAM ndikusintha makamera am'deralo kukhala QAM. QAM RF yophatikizidwa imatha kugawidwa mosavuta pa chingwe cha coaxial (kapena fiber) m'nyumba zilizonse zogona, kuwulutsa SD ndi HD makanema opanda STB yowonjezera pamaso pa TV yanzeru.
Ndi kapangidwe kake kophatikizana komanso ntchito yamphamvu, GWD800 imagwiritsidwa ntchito kwambiri pamsika wamalonda monga mahotela, zipatala, madera, makalabu ndi masukulu komanso makina apakompyuta a digito.
