Who needs an X75?
X75
customer profiles and categories are listed below:
Video Engineers — looking for frame synchronizers for input processing, timing and lip sync
corrections.

Audio Engineers — looking for multi-channel processing for multi-language and surround sound
applications, and Dolby

(AC-3) decompression.
Editors —looking for a “box” to convert and time-base correct all of the analog, digital and high
definition signals required — specifically in edit suites supporting high definition and legacy tape
machines.
Operations Staff — needing to “tweak” signals for processing purposes.
Systems Designers — looking to fit more processing in a smaller space, a device that can handle all
analog, digital and high definition signals with full audio processing, plus field upgradeability to
HDTV.
DPS-575 Users — wishing to add-on more processing devices to their system, and who may need high
definition in the future.
Users of first generation competitive high definition products — needing to replace that equipment.
HD started in 1998, and most first generation equipment has been (or will be) replaced.
Applications
There is still a requirement for SDTV processing. The X75SD fills the need for a 1RU device with future proofing
for HDTV. There are more and more processing applications for HDTV worldwide, with requirements in Asia
(Japan, Taiwan, Korea, China), Australia, North America and Europe.
Primarily, the
X75
will be used for:
HDTV Mobile Production
Live Broadcasts for Sports and Music
Satellite ingest for genlocking and timing purposes.
Other applications exist in news and production.
The X75 is designed for many applications, as described below:
Mobile
X75 is built for use in mobile environments with fast operator controls, automatic input selection of
composite, SDI or HD-SDI inputs to the proper HD output format. These factors combine to make
X75 the easy choice for “live event” input processing. Mobile applications may require a mix of
X75SD and X75HD s. The X75SD is future proofed with field upgradeability to HDTV as required.
Satellite
X75 provides frame synchronization with audio processing and delay for any input signal type to many
output signal types. In satellite gathering and uplink facilities, the X75 ’s noise reduction plus audio
limiting is ideal — ahead of the compression encoders.
