The Vislink ViewBack is a lightweight, low power, low latency, dual channel diversity receiver-decoder, intended primarily to provide reception of return studio video transmission back to the camera operator.
Operating in the 2GHz licenced band, the receiver supports Vislink proprietary robust LMS-T demodulation in addition to low latency H.264 decoding.
Outputs include HDMI and HDSDI, the latter being switchable, in wireless camera applications, between the local camera video and the return received video. A lens interface is provided to utilise the ‘return’ button of the camera lens for switching the HDSDI output.
On switching, picture interruption is avoided by use of local ‘frame lock’ information extracted from the camera source.
The Vislink ViewBack is supplied with flexible quarter-wave antennas, and various mounting options for camera and Steadicam rigs.
Other applications include reception of camera/studio output to a ‘production’ monitor on set, or as a wireless ‘autocue’ receiver.
User control is via Bluetooth™ using the Vislink App, currently available for Android devices.
