Motorsport

Link systems are used extensively for motorsport coverage where compact design, lightweight/rugged construction and reliability are key. Only the best equipment survives in this harsh environment – which is why Vislink supply on-board equipment to the two most demanding events in motorsport - DTM and the ultimate challenge, the Le Mans 24 Hour Race.

Key features include:

  • LMS-T
    • Gives vastly superior performance to DVB-T based systems. At high speeds, reflections from catch fencing, crash barriers etc cause received signal amplitudes to vary extremely rapidly. LMS-T receivers can track signals 4 times faster, significantly reducing picture break-up. This greatly reduces the number of receive points required, cutting down rigging times and expenditure on equipment.
    • Allows the transmitters to run at lower power settings, giving cleaner signals and enabling channels to be tightly packed together, saving valuable spectrum
    • Higher bit-rate capacities of 9MB (QPSK) and 19MB (16QAM) mean multiple cameras can be multiplexed together and transmitted on a single RF channel. This eliminates the need for on-board cameras to be pre-switched and gives the director full view of all cameras at all times. This also frees up personnel and valuable channel space.
    • 7GHz on-boards a reality - Recent tests carried out by Link Research confirmed our 7GHz LMS-T On-boards out perform 2GHz DVB-T systems!
  • Deep Interleaving
    • The next leap forward in RF technology, deep interleaving can fill in gaps in transmission caused by cars/bikes passing bridges, gantries etc and compensate for flat fades and bursts of interference commonplace in the motorsport environment
    • Working in tandem with LMS-T, deep interleaving can help reduce receive infrastructure even further, freeing it up to cover other events
  • Active antennas
    • Our motorsport systems are available with active antennas. These are powered via the RF cable and have a built-in AGC allowing extremely thin (RG316 2.8mm diameter) cables to be used instead of large, inflexible low-loss cables required with passive systems. This minimises rigging time and weight
