The SKD201X Encoding & Modulation
Modulator is the most cost-effective and factory-solution of digital
modulator in the overseas market. With
the second HDMI output port and a RF loop port, the user can easily install the
system with different requirements. Extremely compact and wall mountable, the
SKD201X encoder modulator fits into any space virtually.
The HD signal can be modulated into
various formats, such as, ATSC, DVB-C (J.83A/J.83B), DVB-T, ISDB-T and DTMB
after being encoded by MPEG2 standard.
Application:
The HD loop output
can be widely used in the home entertainments, security monitoring, Hotel TVs and
Shopping Mall advertisements and so on.
1. Extremely compact with less than 3CM height
2. Support MPEG 2 encoding
3. MER greater than 35dB
4. Integrated HDMI output for HD content quick display
5. One HD (RF loop) input and one HD loop (RF) output
6. PC network management and digital tube display panel can allow for easy
set-up and control via the web browser.
