Description:
The SDM-2 is 2 composite video inputs standard definition DVB-T, DVB-C and J.83B COFDM modulator which provide COFDM RF signal in range of 50 to 860MHz. The SDM-2 is designed to achieve 576i/480i by using MPEG-2 low latency encoding engine and state-of-the-art COFDM modulation technologies. The SDM-2 is an excellent choice to transport video/audio signals from TV satellite receivers, surveillance camera or video/media players to a LCD TV or set-top box.

Product Features:
 Integration of Encoder, TS Mux and DVB-T, DVB-C or J.83B COFDM Modulator in one box. 
 Multi-channel video interface, 2 composite video (CVBS) 
 Multiple audio format compatibility including MPEG-1 Layer ll
 RF output, DVB-T, DVB-C and J.83B COFDM compatible.
 Frequency Range: 50 to 860MHz
 Programmable PMT/Video/Audio/PCR PID
 Programmable Network ID, Network Name, Service Name, Private Data Specifier and Logical Channel Number
 User friendly configuration of RF frequency via Knob and remote Web server control by LAN
