GENERAL DESCRIPTION
- This is a composite video input standard definition DVB-T HD modulator that provides COFDM RF signal in VHF and UHF ranges.
- It is designed to achieve HD input, and it only supports standard H.264 encoding.
- It is an excellent choice to transport HD signals from TV satellite receivers, surveillance cameras or video/media players to an LCD TV or set-top-box. It can be used in series with another modulator so the number of channels in the coaxial cable no the SMATV system can be increased as desired.
