Application Example 4 - Broadcasting of Golf Tournament
Click image to enlarge.
  • Each LWB-16M is placed under a tree or TV camera tower near the tee (T) or green (G) and each LWB-64 is placed in the temporary booth and the OB van (relay broadcast center). In total, four LWB-16Ms and six LWB-64s are used.
  • In each temporary booth, the audio signals of each hole are mixed and sent to the relay center. PGM mix audio and monitor video (2-channel SDI in this example) signals are sent from the relay center to the booths for the mixing engineers, announcers and commentators. Intercom signals are transmitted between each point. As shown in the illustration above, the 2-wire and 4-wire intercom types can be connected to the LWB at the same time without any converters.
  • To power the LWB-16M when it is hard to get power from nearby, the LWB-64 powered from the generator vehicle or generator sends AC power via the fiber-optic camera cable.
  • In this example, communication between the units is doubled by making a loop connection with fiber-optic camera cables. If this doubling (redundancy) is not necessary, you can start dismantling from the finished holes. If you plan to dismantle the units and cables beforehand, you will not have to wait until the end of the tournament. This will be helpful for TV crews.
