The UNITY 4000 IRD is an integrated receiver/decoder designed to receive SCPC or MCPC DVB-compliant digital video signals transmitted by satellite. The input to the IRD is an L-band (950-2150 MHz) RF signal which is processed to produce composite video, audio, e-mail output, auxiliary data, and relay cueing signals. The IRD is fully network-controlled via the WCI COMPEL control system.

The optional decryption feature for the IRD allows for use of WCI conditional access. Authorization of each IRD is under network control. In addition to network control, the IRD features a front-panel LCD interface for gathering local status information. In addition, limited control of the IRD (if allowed by the COMPEL network) may be implemented via serial port, connecting either to a local terminal (or via phone modem) to a remote terminal.

The IRD has expansion ports for up to two add-in modules. The UNITY 4000 IRD features several separate hardware components: The DC switching power supply, the main motherboard, an L-band DVB receiver, front-panel keypad controller card, a front-panel LCD assembly, and the L-band RF switch. The DC switching power supply provides all internal regulated DC power. The L-band RF switch is installed in the Module 2 expansion slot, and provides network or (if allowed by the network) local user selection of up to four separate RF feeds. The selected RF feed output is connected to the DVB-compliant L-band receiver card.

This card tunes and demodulates the input QPSK carrier, and then applies two layers of error correction decoding. Its output is the original (possibly encrypted) multiplex MPEG transport stream which was input to the uplink IF modulator. This stream then feeds the main motherboard, which decrypts (if necessary) the stream and then demultiplexes out the selected video and audio elemental streams. These are, in turn, de-compressed and converted back to the original analog source material for output.

Meanwhile, the user may query the IRD using the front-panel keypad for input and the LCD to read the returned status information.
