- La MicroMega - Technologies for Telecommunications

The LMRD-T receiver is a professional equipment designed for DVB-T signals in UHF/VHF band, with ASI output.
Basic configuration provides one DVB-T input, but a second DVB-T, DVB-S/S2 or ASI module with integrated  software multiplexer can be installed.

A common interface module to decode encrypted transport streams can be activated on the main input.
Two hardware options are available to extend the optional DVB-S/S2 module receiving bandwith, one to extend the bandwidth up to 2450 MHz and one to set the input frequency to 70 MHz (standard IF in radio bridges).
Further, other software options for advanced signal elaborations, input remultiplexing or SFN adapter can be activated.

The equipment is managed with a bundle software through an USB or LAN port.
An HTTP server is available on the LAN interface, to allow a local or remote management by means of a browser interface through an IP connection.

The receiver comes with 8 on/off type telecontrol signals (4 opto-coupled inputs and 4 relay outputs), fully software programmable.
