Live Production with EVS

Outside/Remote Broadcasting

With their unique loop recording technology and Multicam LSM software, EVS’ XT series servers have continually set the pace in terms of speed, precision andreliability. Outside broadcast producers and facility companies have come torely on EVS technology for the production of live events requiring ahigh performance level for the acquisition of multiple camera feeds,instant production operations such as: Live Slow Motion, Super Motion, Ultra Motion replays, the insertion of analytical graphics on live programs as well as on-the-fly highlights creations.

Outside Broadcast crews covering live sports want to operate at the cutting edge oftechnology. It’s a pressurized, adrenaline-fuelled environment in which teams must create polished, incisive programming to meet ultra-tight deadlines.

EVS technology is designed to be in the middle of the action, maximizing the numberof key actions and sequences that are instantly available. EVS’ XT series servers and related software applications have set a benchmark forquality and reliability. They have been tested and selected to be used for international regular as well as premium outside broadcast events.

To ensure the production of replays and edits during a live sports event, multiple-cameraSDI feeds are immediately recorded on EVS video production servers' ingest channels installed in Outside Broadcast facilities (OB Vans) at the venue.

These advanced digital video recorders are based on a loop recording process, guaranteeing that no single shot isever missed. Their live-oriented architecture (high level of redundancy andfault-tolerance ensuring that no failure can interrupt the workflow) guaranteea maximum level of control for instant replays, highlights editing, clips compilation, and live graphic overlays managed by OB production teams during an event. Each server can simultaneously ingest and control multiple feeds.

During the production of a match or game, all XT serversinstalled in OBs are linked together allowing operators and production teams toshare content as well as control media which is recorded on differentnetwork servers. Servers are grouped together through a dual media sharing network (XNET[2] network based on highbandwidth SDTI & standard Gigabit Ethernet network). Any feed recorded onone server can be reviewed, clipped and played out from any other server. Thisallows operators to exchange clips and highlights with others, gathering all the best sequences and actions that will then be transferred to the booth.

During the production of matches in OB trucks, all In & Out XT channels of the server can be controlled by multiple software and hardware tools

• Multicam LSM remote controller for all live slow, super (2 or 3 phases camera), ultra motion replays, as well as multi-camera actions for clipping, highlight creations and closers. In addition, EVS LSM controllers can be operated to generate analytical graphics immediately on the live program.

• IPDirector for multi-camera ingest and network control, browsing and logging operations. In addition, a timeline editing module of IPDirector, IPEdit allows the creation of highlights and clip compilations within seconds. With IPEdit, editors benefit from effective timeline performances with no need for media transfer, encoding and decoding processes. Finally, IPDirector acts as a media manager system offering the transfer of clips and sequences onto storage or third-party NLE systems.
