Great Solution For Applications Requiring High Quality
Wireless Video Transmission

The VidOlink COFDM II Transmitter from VidOvation is an HD SDI digital video transmitter specifically designed for Sports, ENG & Mobile production applications. The unit docks neatly onto all types of ENG cameras via integrated V-mount or AB battery plates.

Standard broadcast connectors are used for video (BNC), audio (XLR3) and power (LEMO) inputs and are accessed via a horizontal connection panel. This eliminates clashes with the camera's own connectors, minimizes cable strain and enables the camera to be placed on the ground when not in use.

The increased compression and efficiency of the AVC MPEG4 H.264 encoder offers users additional range with the added benefit of small size, low delay & low power consumption. In particular, very robust data rates are possible using 40% lower bit-rates than conventional MPEG2 systems, enabling true HD transmission in a single 8MHz DVB-T channel while using a lower order of modulation. The unit can transmit images in a non-line of sight environment, over 1/2 mile depending on mode and frequency.

Designed to offer maximum flexibilitv in the limited or crowded spectrum in today's production environment, the VidOlink COFDM II has a variety of video input options including composite, SDI, HD-SDI and HDMI. which is particularly useful when accessing material in the field from pro-sumer and semiprofessional equipment.

Analog audio inputs feature MIC/Line level with variable gain and P12 microphone powering. AES and SDI/HD-SDI embedded audio inputs are also offered as standard. An optional ASI in/out interface is also available, enabling the unit to be used as a stand-alone encoder or modulator.

The VidOlink COFDM II transmitter has an integrated control panel with a very brightly lit OLED display covering all major tunctions and has 16 channels to choose from. A power on-off switch is also provided to minimize camera battery consumption when not in use.
