Experience an Integrated Content Environment
Leitch Technology is uniquely capable of meeting the needs of customers with a full range of products that provide
the experience of an Integrated Content Environment — a streamlined workflow for the production, processing,
transmission and management of content.
The area of content production has seen increases in source and output formats, effects, layers and volume of
material to be edited. As a result, editors need tools that enable increased productivity to offset these additional
time demands, while increasing performance and enhancing creativity.
VelocityQ™running on Quattrus™hardware, including a new interface style featuring the unique EyeCon View, has
received glowing reviews for its “real-time full-quality” playback speed of four video streams, up to six graphic
layers and four 3D DVEs.
Leitch’s new NEXIO™server system, a modular, scalable and highly cost-effective storage infrastructure for news
and transmission environments, includes gigabit Ethernet for easy integration with IP networks for movement of
content. NEXIO features industry-leading productivity — with the introduction of Ingest Control Manager™
,
NewsFlash™server-based NLE, and BrowseCutter™II low-resolution editing system — to provide the fastest and
most effective workflow today.
The advent of fully Integrated Content Environments has led to significant efficiency improvements in workflow,
with processing and monitoring now integrated and transparent.
NEO™
, Leitch’s advanced processing platform, not only hosts single-function modules, but also consolidates multiple
functions on a single “Simplicity” card. New award-winning modules have been added with the NEO VR™digital
video recorder, LogoMotion™II branding tool and the NEO SuiteView multi-source display processor. More
functionality can be achieved by customers’ infrastructure environments with the high-density 6800+™
.
Leitch’s industry-leading routing offerings allow customers to connect high-quality signals of all formats from
analog to HD. Panacea™provides affordable, compact, modular routing in sizes up to 32x32. The new wideband
Integrator®Gold provides scalable routing of almost any digital signal up to 128x128 in a single frame. All
processing and routing platforms are fully integrated with Leitch’s advanced Command Control System (CCS™).
Advancements in digital technologies have enabled more channels, in different content formats, over multiple
distribution systems. Customers now seek to achieve their vision of a fully Integrated Content Environment to supply
multiple distribution channels with high-quality content and branding.
Leitch’s NEXIO transmission server, which supports multiple compression formats in both standard and
high-definition resolution, will also support ASI interface and has the ability to record, process and playback
MPEG transport streams.
Leitch’s Opus™master control switcher offers an array of effects and has the ability to control up to
16 on-air channels. Opus meets multi-channel digital integration challenges for both high-definition and
standard-definition formats.
Integrated Content Environments offer the greatest opportunity for productivity and performance gains when
employing content management and control applications that place content, operations or remote locations under
common software controls.
A major workflow enhancement is Leitch’s Ingest Control Manager™
, which places control of up to 16 server
channels with associated proc amps (DPS-575), eight VTRs and eight separate routers under one control station.
Leitch’s CCS Navigator™
, winner of NAB 2003’s highest awards for control and monitoring of content quality,
and the CCS™soft real-time system provide open access through standard protocols to components
of a networked system.
