COFDM DVB-T Compliant Receivers with Built-in Remote Antenna Controller

Network Managed UDP Video Streaming Diversity Receiver with Remote Site Controller

two to eight input diversity receiver

Troll’s DMR series of products combines a multichannel DVB-T microwave receiver with a remote site diversity antenna controller. The combination provides a two (2) to eight (8) channel diversity receiver for remote Electronic News Gathering (ENG) or law enforcement antenna sites. The DMR processor performs video decryption, encryption, video and audio decoding for local monitoring and secure IP transport to remote control centers.

The DMR’s front panel touchscreen enables live video and audio preview, control and monitoring of antennas, transmission, test and signal diagnostics. In addition, video can be viewed locally via HDMI, Ethernet or composite. DMR6000 receivers can be daisy chained together to receive multiple RF signal sources on different channels simultaneously. This passive “loop through” feature makes it possible to support multiple aircraft and ground vehicles with a single diversity antenna. DMR receivers incorporate Maximum-Ratio Combining and packet switching to “knit together” signals from different antenna panels to provide cohesive 360° coverage.

Like all Troll equipment, the central receiver is designed to be rugged and reliable for years of service in adverse environments. Careful attention to design and manufacture assures performance and reliability, especially in highly saturated RF environments that are common to remote ENG and XNG facilities.

The DMR system provides remote control of the entire receive site. The modern design incorporates the latest networking technology, with extensive packet-level advances in diagnostic and test capability. A Linux operating system delivers remarkable performance while providing an Ethernet compatible platform for delivering encrypted HD video and data over IP.
