Digital Video Over Analog (DVA) Encoder and Decoder
AMP’s DVE1 Encoder / DVD1 Decoder Digital Video over Analog (DVA) system enhances existing analog FM video systems by providing payload encryption, increasing link range, reducing occupied bandwidth, improving picture quality, and extending the flexibility of traditional analog video systems.
The DVE1 Encoder, installed between the camera and FM transmitter, digitizes and compresses the video and audio inputs, folds in optional auxiliary data, and then encrypts, error-corrects, maps, filters, amplitude-scales, and de-emphasizes the digital stream to counteract the transmitter’s pre-emphasis. The DVD1 Decoder, installed between the FM receiver and monitor, reverses this process and provides composite analog video, up to stereo audio channels, and auxiliary data outputs. No modifications to the NTSC or PAL analog FM video system are required.
Video, audio, and data port settings and rates are user-configurable. A 10-position rotary switch accessible through the chassis lid provides real-time remote control and programming (position 0) and utilization of 9 programmable pre-set configurations (positions 1-9).
AMP’s DVA system may be ordered with rugged aluminum chassis and connectors for addition to existing FM systems, as stand-alone PCBs allowing custom installations, and as integrated assemblies in our new 2011 E-series analog FM radios for the ultimate in analog performance.
