Link Research launches new digital wireless camera system

Link Research is adding a second digital wireless camera system to its range - the LinkXP2 with reverse camera control for sports applications.
Link is also launching a new digital Triax solution to carry the signals from the LinkXP systems back to the OB vehicle. A reverse control Upgrade package is also being launched for LinkXP1, enabling camera control as with LinkXP2. The LinkXP1 upgraded system can be used on a camera back, but is also ideal as a modular system for vehicle use. Both LinkXP systems deliver clear, reliable pictures for live broadcast with almost no signal delay - just 40mSecs, equal to one frame.
Link offers professional broadcast-quality DVB4:2:2 video with standard MPEG encoding and diversity antennas that give a robust signal as the cameraman moves around. If the signal should drop, it has instant recovery. The power requirement for the system is below 20 watts.
The new LinkXP2 system is supplied as a complete camera back with a Sony BVV-5 interface, which makes it compatible with all broadcast cameras. The system now incorporates an LCD control panel to configure the system for different manufacturers' cameras and new, improved down-converters to reduce interference from other RF signals in close situations.
There are now optional power amplifiers, which can extend the range of the systems.
With digital wireless camera systems rapidly replacing analogue equipment, Link Research has already anticipated the final step needed for end-to-end digital broadcasting - digital transfer over Triax cables.
The new digital Triax solution from Link Research will allow broadcasters to deliver output from their cameras in digital format over existing Triax cables, with no degradation to the quality of the pictures. In trials, Link Research sent camera pictures over distances as long as two kilometres with no loss of signal. This system has been on trial for many months and has operated faultlessly with none of the signal degradation experienced with analogue Triax systems. The Digital Triax solution is supplied as two components: the L1271 Triax base unit, supplying power and receiving the modulated ASI signal and the L1272 Triax remote unit accepting the modulated ASI input and providing power to the local receivers.
Link Research was launched by David and Len Mann, in order to produce equipment for the field of professional TV. As well as reselling other companies products, Link manufactures its own encoders, encoder/modulators and the LinkXP wireless camera system, which won the IABM's Peter Wayne Award for Design and Innovation 2002.
