DTC Video Receivers

DTCs Vortex Diversity series of video receivers offer superior video performance in mobile environments by incorporating DTCs VideoVoter technology. A pair of receivers are housed together, each with its own antenna. The VideoVoter board looks at the output of each receiver simultaneously, selecting and switching to the best signal at over 15,000 times per second. Up to ten user preprogrammed video frequencies may be selected via a rotary switch. Each video frequency has two user programmable audio subcarriers as well. The audio subcarriers are phase locked, and will not drift over time or temperature. User programming software and a programming cable are provided with each unit. Two video outputs are provided, one composite and one video only. The composite video output is ideal for retransmission, as the audio subcarriers are embedded in the signal. The video only output is typically connected to either a local monitor and/or recording device. Two audio outputs connectors are provided. Received Signal Strength Indication (RSSI) is available in three ways: First, through a local bar graph display. The display may be disabled after set up to conserve battery life. Second, as an analog voltage on one pin of the multipin connector. Third, through the serial communications protocol supported via the multipin connector. This is an ideal way to retrieve RSSI when the receiver is embedded in other devices. Internal encryption using the Ovation Micro- Viewlock II module is supported as an option. Encryption On/Off is selected from the front panel.
