EVS
demonstrates slow motion servers A day at
the races
To demonstrate its newest
range of slow motion servers and software in a live set, EVS, the Belgian
slow motion server company, recently invited its German broadcast customers
to a racing centre near Frankfurt, with hands-on opportunities for operators
and engineers. In conjunction with
Philips, who delivered the camera system, and AVS, who supported DVB
transmission of video signals from racing carts, they showed new features and
hardware options that are launching at NAB 2001. The new generation of
servers comes with two different configuration settings: four recorder
channels plus two players or three-by-three channels. Different
configurations can be recalled during the boot-up procedure so the system can
be pre-configured for different applications and set up easily. Although the interface
layout has not been changed, the operation is slightly enhanced. On top of
the 'slomo' replay and editing facilities, the EVS six-channel live slow
motion system supports the analysis and illustration options such as
Telestrator, Target Track & Split Screen. Both access times and reboot
times are reduced (less than one minute) as well. With the effects/mix
board the six-channel version can create wipes and dissolves of internal
signals directly from the disk. Loop recording mode and non-destructive clip
length come together with new keyboard short cuts, which enable easy renaming
of clips with standard names and titles. The disk controller has a total
sustaining bandwidth of more than 240Mbps, allowing at least six simultaneous
channels at 40Mbps. Embedded audio is used in conjunction with M-JPEG As EVS' Marcel Groos
said: "At IBC 2001, file export in MPEG-2 compression format will be
available. So stay tuned when you are looking for an LSM system." File transfer over SDTI
interfaces will be shown on a prototype machine at NAB. With this networking
capability, several server mainframes can be interconnected over standard
digital coax cable, available on every OB truck. This will allow access to
other users on remote control stations to a connected storage device. Philips' LDK 23HS Mk II
offers some new features. It is now possible to reduce the flicker of
artificial lighting. Besides the solution for sport events, the LDK 23HS Mk II
is also applicable in studio applications. A factory upgrade will be
available for the installed base. At the German demo,
signals from the Philips cameras were transmitted via MPEG-2 encoders from
Tandberg and transmitters/receivers from AVS to the server system from EVS. New
DCL transmission technology from AVS cancels ghost pictures and colour
deviation. With the new DCL series generation 3, to be shown for the first
time at NAB (on the Tandberg booth), transmitter and receiver housings are
less spacious and picture quality is increased. Finally, EVS announced
CineStore, the digital cinema server that will be available in September. CineStore
is compatible with the 24p signal for Barco, Christie and Digital Projection
equipment based on DLP Cinema Technology from Texas Instruments. It can
deliver high-quality images achieved through an advanced optimisation of MPEG
parameters. |
