I-GWD800 IPQAM Modulator
Incazelo Yomkhiqizo
I-GWD800 iyi-IP yedijithali eya kumoduli ye-QAM ku-chassis engu-19” 1RU, eklanyelwe ukubhekana nesidingo esikhulayo se-compact, high density kanye ne-mini headend ebizayo yezinhlelo ze-TV zentengiso. I-GWD800 iqukethe amamojula angu-3pcs SKD180X aphezulu, imojula ngayinye ye-SKD180X ikhipha izithwali ze-RF ezi-4, ezilawulwa yiphaneli yangaphambili i-LCD nezinkinobho noma imbobo yokuphatha inethiwekhi. Okokufaka kwe-IP kusekela i-UPD, IGMP V2/V3 kanye ne-TS re-muxing. I-GWD800 eyodwa ingaguqula okuqukethwe kwe-IP kube amasiginali aphezulu we-12ch QAM RF. Okukhiphayo kwe-QAM RF kusekela i-DVB-C (J.83A/B/C), i-DVBT, i-ATSC.
Okuqukethwe okuyinhloko kwanoma iyiphi i-headend encane kuvela kumasathelayithi, i-inthanethi, i-terrestrial TV namakhamera endawo. I-Mini-head kufanele ikhethe ividiyo efunwayo kwisathelayithi ne-inthanethi, ihlanganise ividiyo ekhethiwe ku-TS entsha. Njengoba ama-TV amaningi ahlakaniphile angathola amasignali edijithali e-QAM RF ngokuqondile, kwenza izinzwa ezengeziwe kubaqhubi be-TV abathengisa ukuguqula i-DVB-S/S2 ibe yi-QAM, baguqule i-IP ibe yi-QAM futhi baguqule amakhamera endawo abe yi-QAM. I-QAM RF ehlanganisiwe ingasatshalaliswa kalula ngekhebula le-coaxial (noma i-fiber) kunoma yiziphi izakhiwo zokuhlala ngendlela eyongayo, isakaza i-SD kanye HD amavidiyo ngaphandle kwe-STB eyengeziwe ngaphambi kwe-smart TV.
Ngokuklama kwayo okuhlangene nokusebenza okunamandla, i-GWD800 isetshenziswa kabanzi ezimakethe zezentengiselwano njengamahhotela, izibhedlela, imiphakathi, amakilabhu nekhampasi kanye nezinhlelo ze-TV zedijithali.
Izici:

•Isekela amamojula we-IPQAM aphezulu angu-3 axhumekeka kalula.
•Imojula ye-IPQAM inokufaka okungu-1 kwegigabhithi ye-IP kanye nokukhishwa kwe-RF okungu-1 nabathwali be-frequency agile aba-4.
•Okokufaka kwe-IP okusekela i-UDP, IGMP V2/V3.
•Ukusekela i-TS re-muxing.
•Okukhiphayo kwe-RF kusekela i-DVB-C (J.83A/B/C), i-DVBT, i-ATSC.
•Imvamisa Yokukhipha Iyalungiseka phakathi kuka-50MHz no-1000MHz.
•Ukulungiselelwa kwe-LCD yendawo noma ukuphathwa kwenethiwekhi okukude.
