1.Support 1 channel ASI input (optional)
2.Support 1 channel TS over IP(UDP) input/output
3.Support 2 channels ASI output
Overview
YDN-IRD2208 SD IRD could receive RF signal from DVB-C LNB input (TS stream met MPEG2 regulations), and Decode for A/V signal output. Configured CAM interface, could crack the encryption program. Also could bundled up all the TS stream signal to IP package (UDP), transport by network. User can choose the system for 1 or 2 channels ASI output interface. Mainly for bureau of radio and television head-end DTV signal monitor, applies to TV wall surveillance, replace DTV STB, save space greatly
