The included accessories

SIGNAL-752 R86752 is a multifunctional device that encodes two input HDMI signals to IP stream and modulates RF signal (a set of carrier frequencies) in accordance with DVB-T standard (COFDM). The signals provided to the HDMI inputs can vary from SD to Full HD.
The device has 2x HDMI (plus 2x spare HDMI) inputs, RF input, and RF (DVB-T) plus IP outputs.

The device is a two-channel modulator, which means that the output DVB-T multiplex can contain two channels modulated by the source signals. 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 signals may come from media players, DVRs, Blu-rays, PCs, STB decoders 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).

Another advantage of the device is the ability to provide parallel UDP/IP stream (IP multicast technology).

Basic configuration settings such as output frequency, stream bitrate, the type of the modulation are performed using the buttons and display located on the front of the modulator. More advanced configuration options are available through http protocol (NMS - Network Management System).

The device is intended for mounting in a rack cabinet.
