SDM-T1 is a composite video input standard definition
DVB-T modulator which provides
COFDM RF signal in range of 45-860MHz.
It is designed to achieve 576i/480i (PAL/NTSC) by using MPEG2 low latency encoding
engine and state-of-the-art DVB-T modulation technologies.
It 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.
It can be used in series with other SDM-T1 so the number of channels in the
coaxial cable on the SMATV system can be increased as desired.
• Single input modulator that converts analogue A/V source to a DVB-T channel
• Programmable channel name and logical channel number insertion (LCN)
• Multiple video format compatibility including 576i(PAL) and 480i(NTSC)
• Multiple audio format compatibility including MPEG-1 Layer II
• Frequency range : 45~860MHz
• High output level up to 90 dBuV
• Carriers 2K and 8K
• Programmable video/audio/PCR PID
• User friendly setup and control
• Compact and wall mountable
