Txheej txheem cej luam
DIGICAST Encoder mdolator series uas hloov cov yees duab digital thiab suab (HDMI) teeb liab / IP / ASI rau hauv lub teeb liab FullHD (MPEG{0}}/H.264) rau hauv DVB-T/C/ATSC/ISDB/DTMB channel . Cov tswv yim digital teeb liab los ntawm lwm qhov chaw SD / HD: satellite txais, DVR / NVR, DVD, CCTV, thiab lwm yam.
Cov channel tsim los ntawm HDMI qhov chaw tuaj yeem sib xyaw nrog DTT teeb liab thiab tom qab ntawd muab faib rau ib qho coaxial cable. Nws cov ntsiab lus tuaj yeem tso tawm rau txhua qhov tau txais cov khoom siv ntawm qhov system.it yog lub tswv yim daws teeb meem rau kev ntxig ntau cov kev pab cuam los ntawm loca / internet mus rau coaxial sytem uas twb muaj lawm, dav siv hauv tsev so / tsev kho mob / khw khw ... lossis CATV cov neeg ua haujlwm.
