EVS Broadcast Equipment Americas: Live Slow Motion
While traditional sports controllers work fine when commanding linear VTRs, they do not always meet the needs of multi-access video servers. The EVS LSM (Live Slow Motion) server is a prime example of the extended functions that require a specifically designed remote controller.
The LSM multi-access video server allows operators to highlight playlists and continuously record multiple camera angles while playing previously created clips. The LSM can be configured as a basic 2-channel system with one record and one play channel, or up to a complex 6-channel system with a multiple number of configurations for record and play. In addition to basic record and playback, the LSM also allows operators to perform extended playback functions; such as multi-colored telestration over highlights, spot shadow effects with keyframes, split-screen playback with positioning, and control of each side of the effect. It is for these reasons that EVS designed the LSM remote to control this flexible video server and its many features.
The LSM remote uses a built-in LCD screen for viewing menus, functions, and server channel status. Operators can generate time code cue points similar to other sports controllers, but with the ability to mark cues on the recording video while playing back a separate replay. The primary function of the LSM remote is to facilitate the creation of clips into the systemâs database. This allows an operator to make video and audio accessible instantly and organize it with metadata that includes names, time code, keywords, and other information. Once clips are created, the operator uses the remote to quickly build non-destructive playlists with effects. These playlists can even be edited during playback to allow highlights to be added, deleted, trimmed, and manipulated moments before playback.
The third generation LSM, named LSM-XT, can now be networked to form a large integrated production system. This networking is called Sportnet, and it allows operators to share recorded video between systems instantly, eliminating the need to transfer video through the router.
The LSM-XT also allows linear editors and standard sports controllers to control independent channels of the LSM-XT with such standard protocols as Odetics, Louth, Sony, and DD35. In addition to the LSM-XT, Sportnet has other devices that make the network complete. The maXS is a 4-channel server intended to replace two VTRs, and also features the ability to be controlled by standard controllers, editors, and switchers. The entire Sportnet system is intended to begin replacing the VTR limitations of current day productions.
