EVS, Broadcast Industry supplier of live video production systems, trialled its XT3-LSM system for the first ever live 4K replays during the recent Champions League semi-final between Bayern Munich and FC Barcelona.
This trial follows on from the success of an initial live 4K trial for outside broadcast production company Kyodo Television in Japan, as well as private 4K demos which were held at NAB2013. Outside Broadcast (OB) company TopVision turned to EVS to run a live 4K test for replays to run alongside their live HD live broadcast. A Sony F55 camera was tied electronically to an EVS XT3 server and an AJA Corvid that allowed operators to zoom into the picture and replay segments in slow motion. As the XT3 was designed to be future proof and was built with flexible configuration in mind, it allows bandwidth and storage capacity to be tailored to suit the application and the user.
For the recent Champions League match in Munich the XT3 4K solution was configured as a one-in, one-out system. This enabled continuous recording while providing random access replays to of any 4K content on the server simultaneously. However, EVS
are also working on a solution to utilise and harness the data of up to three 4K channels on one XT3, either two would be recording and one replaying or one recording and two for replays.
Luc Doneux, head of EVS’s SVP Sports division, ad this to say “Replays from alternative camera angles, slow motion and close ups that capture every detail are now something that sports fans expect their broadcaster to provide and this will remain a vital requirement for 4K and beyond.”
