HDMI/USB - COFDM (DVB-T) Modulator: Signal-450
SIGNAL-450 R86740 is a multifunctional device that encodes input HDMI signal to transport stream and modulates RF signal (a set of carrier frequencies) in accordance with DVB-T standard (COFDM). The input signal can vary from SD to Full HD. The device has HDMI, USB and RF inputs and RF (DVB-T) output.
The device is a single-channel modulator, which means that the output DVB-T multiplex contains one channel modulated by the source signal. Wide configuration options allow for combining the output DVB-T multiplex with existing DVB-T broadcasts distributed in the system, in a manner chosen by the administrator or investor (adjustable parameters include LCN, SID, PID, NIT).

When the user needs to distribute two channels from two different signal sources, we recommend to employ two-channel model Signal-752 R86752.
The source signal may come from a media player, DVR, Blu-ray, PC, STB decoder etc. So, the modulator can distribute highest quality content in DVB-T standard, via cable television installations (shared/MATV antenna systems), including professional applications in industrial/campus/hospital/commercial TV and CCTV systems.The maximum output bit rate is determined by DVB-T standard (31.68 Mbps, with a maximum bit rate of the video stream of 19.5 Mbps).
The device offers an attractive alternative to installations based on HDMI splitters and cables.
All parameters are set with buttons and shown by the display located on the front panel of the modulator.
Signal-450 has been equipped with USB port allowing for recording the source material in .ts format and playing back the same or other material prepared in .ts format. The manufacturer provides the suitable software for converting various content such as pictures, music, videos etc. into .ts files. It means that the device can work independently, generating the output DVB-T signal based on the .ts files played back from a USB drive.
