Extremely Flexible Wireless Video Receiver and Decoding Platform

OVERVIEW

The VidOlink COFDM II Reciever is a feature rich multi-way diversity COFDM receiver designed to work with the next generation of H.264 wireless camera systems.

Designed specifically for the demanding broadcast market, it is supplied in a 1/2 19" 2U high rack receiver chassis, where two units can be mounted together to occupy a 19" slot and uses standard broadcast connectors for signal interfaces. It is available with 2-way, 4-way, 6-way maximum ratio combining RF inputs, ensuring video is free from the distortions typically associated with multipath.

All DVB-T 6/7/SMHz modes are supported, enabling broadcast quality SD signals to be transmitted in only 2.SMHz bandwidth. Designed to work with external Wave Central down-converters, the receiver can be located up to lOOm from the antennas using standard 7SQ co-axial cables. 

The VidOlink COFDM II Reciever incorporates an extremely flexible decoding platform, with low-delay SD and HD H.264 decoding capability plus an SD MPEG2 decoder for compatibility with existing systems. Multiple video output formats are offered with composite and SDI outputs in SD mode and HDSDI and in HD mode. SDI/HD-SDI both feature embedded audio and a HDMI output is provided for use with domestic TV's. A full Genlock facility is
available in both SDand HD modes. When in HD mode, an optional downconverted SO composite video monitoring output is also offered.

The VidOlink COFDM II Reciever can be controlled through its OLED front panel display, as well as on its RS232 or IP Ethernet browser control interfaces. For customers wanting to distribute received video to remote locations, it is supplied with ASI and optional IP streaming outputs. A comprehensive On Screen Graphical display is available for monitoring and diagnostics, which can be enabled or disabled separately on the composite and SDI outputs.
