ST-6510 R86804 modulator is a multipurpose device that encodes and modulates up to four HDMI signals into one DVB-T multiplex. Aside from four HDMI inputs and RF OUT output, the device has RJ-45 port for configuration purposes.
The device has four audio/video channels (four HDMI inputs with HDCP support). The output DVB-T RF channel (one digital multiplex) carrying all the signals can be combined with any DVB-T signals distributed in an existing MATV/SMATV system in a multi-dwelling unit, hotel, hospital, shopping mall etc. High quality of the output signals is guaranteed by H.264 video compression with automatic bit rate for each of the four streams. Instead, the bit rate for each channel can be set with MANUAL function within 2..6 Mbps range.
The source signals may come from multimedia players, DVRs, Blu-ray players, PCs, STBs etc. The modulator can distribute high quality content in the form of DVB-T multiplex via typical RF coaxial cables used in antenna and CCTV systems.
RF modulators are not used only in antenna systems (MATV/SMATV). Sometimes, the distribution of signal A/V signals via coaxial cable (after conversion to RF signal) is much simpler and less expensive than other solutions - especially in situations where the signal has to reach multiple points (receivers). An example is an electronics store, where an HDMI -> DVB-T modulator eliminates the problems with splitters and tens of HDMI cables that could be used for the distribution of the demonstration content to tens of televisions.
Increasingly, larger antenna devices are designed for placing in RACK cabinets to ensure highest installation standards and protection against accidental damages. The housing of the modulator is compliant with RACK standard.
All parameters can be set via RJ-45 port with the use of a web browser (the default IP address: 192.168.15, password: 1234) or with buttons (and shown by the display located on the front panel of the modulator).
