The included accessories
SIGNAL-400 R86700 is a multipurpose digital modulator (DVB-T - COFDM) with HDMI input and USB interface, capable of processing SD, HD and Full HD signals. The output RF signal can be combined with any other TV signals.
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).
The source signal may come from a multimedia player, DVR, Blu-ray player, PC, STB etc. The modulator can distribute high quality content in the form of DVB-T multiplex via typical RF coaxial cables used in antenna systems. The maximum bit rate is limited by the DVB-T standard (31.68 Mbps), whereas the maximum bit rate of the video stream cannot exceed 18.0 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.
