LIVE SERVER TECHNOLOGY
platforms, intelligent media browsing
based on descriptive metadata
and logging to automated media
digitization and robust processes for
instant transcoding for greatly simplified
promotion and distribution
of content.
Record, edit and play out -
simultaneously
Other developments, including
nonstop "loop" recording, of some
advanced live servers represent significant
advancements to the production
process. Guaranteeing uninterrupted
multichannel recording and access to
recorded content at any time, loop recording
ensures that all recorded media
is instantly available throughout
the production network.
Recording starts as soon as the server
is booted and remains on until the
server is shut down. Recording capacity
can be configured separately for
each recording channel, and selected
sequences can be protected and kept
for as long as required without interrupting
the recording process. Thus,
content is available for simultaneous
preview, rough editing, archiving,
playback or post production.
Editors can browse and retrieve
media while the server is
still recording them, a significant
productivity improvement compared
to the old VTR workflow. It also
allows operators to simultaneously
cultivate content via clips and edited
playlists, while producing rough -cut
edits and transferring content to
post production.
Playout automation
Reliability is perhaps the most important
feature of any production
process, and nowhere is this more
significant than playout. But any automated
playout system must also be
dynamic, flexible and redundant. And
playout is affected by the processes
earlier in the chain, such as intelligent
metadata during ingest. Playout
automation for long -form content
requires flexibility as well as highly
efficient file transmission. The beauty
of the best systems is their ability to
remain controlled by automation
while also enabling last- minute edits
to be performed - only seconds
before broadcast.
On the horizon
We surely haven't seen the end of
media server innovation. Tools will
continue to get better and faster. But
server technology won't just reduce
production time; it will redefine it.
With the rise of applications for, and
integration with, second screens, it
will be more about transformation
than optimization.
Next -generation servers will also
be able to support multiple codec
types in parallel. When recording
video feeds, the encoding process will
start simultaneously, making content
immediately available for exchange.
Providing people in remote locations
with full workflow access and
participation capability is another
sure byproduct of our times. Access,
speed and innovation will continue to
transform how we work and what we
see on screens of all types. BE
