Digital Video Return System

The Digital Video Receiver Terminal (DVRT) avoids the need to dedicate fiber & optical transmitters/receivers to backhaul PEG channels or other local content (surveillance cameras, CGs, etc.) by utilizing unused spectrum. It is ideal for inserting locally generated content (information channels, etc.) to communities serviced by multiple nodes such as gated, retirement & large resort communities. The DVISm unit is used for local baseband encoding into MPEG2 format and modulation into 16QAM-A format while the optional pluggable down-converter card (DV1DN) allows DVISm to output QAM in 5-65 MHz range. The DVRT features variable QAM-A bandwidth (3-8 MHz) for easy insertion into available return band spectrum. It's low order QAM mode provides for resilience in return band deployment, withstanding inherent noise & other impairments. It is used at the destination to demodulate & convert QAM stream to ASI, IP, SDI or baseband (CVBS) outputs to be fed back to desired nodes. The DVRT is also available with integrated up converter (DVRT-UP) for use in applications utilizing the DVISm down converter. It can accommodate return via direct insertion to return transmitter (in nodes & networks supporting this architecture) above return band frequencies to preserve all return band spectrum.
