The HFS-975 provides Up, down, cross and aspect ratio conversion with synchronization. Audio processing
of the AES audio delay may require increased audio delay for proper lip sync. There are four channels of AES
audio to accommodate the requirements for surround sound applications is one of the many features of the
HFS-975. The ability to take legacy analog video signals into the digital domain using the highest quality
conversions before up converting and compressing video signals is a natural for this professional frame sync.
The HFS-975 will compensate for long cable runs up to 300ft, depending on signal output.

HD & SDI FRAME SYNCHRONIZER

MODEL HFS-975

900 SERIES

MADE IN THE USA

The HFS-975 provides conversion for almost any signal type for HDTV video. For the analog environment,
it can time base correct any tape format, analog, SDI or HDTV to house master black. The HFS-975 can
perform up-conversion for HD output, down-conversion for monitoring, and cross-conversion for programs that
are recorded in other than the native format. The video-to-audio timing are adjustable to maintain lip sync. This
makes the HFS-975 first choice the most demanding requirements. The integrity of Closed Captions are
maintained.

The HFS-975 Multi-Format Converter and Frame
Synchronizer is a standard and high-definition
synchronizer and converter. It combines video and
audio processing capabilities with the ability to up­convert, down-convert, and cross-convert from
most input video formats to almost any output
video format.

The HFS-975 is equally suited for analog, digital or
hybrid facilities, and represents the ideal choice for
the professional user, making the transition to
digital television affordable. This single unit comes
standard with composite analog, component video;
Y/C, HD and SDI, as well as AES embed and de­embed. The HFS-975 multi converter synchronizer
provides an ideal bridge between analog, digital
and high definition systems with analog, digital and
embedded audio.

Closed Captions are passed transparently from
input to out, through all down, cross and aspect
ratio conversion. The entire vertical interval is
passed to the output without degradation.

A complement of SDI test signals are provided on
the analog and digital outputs of the HFS-975.
Audio test tones are selectable for embedding of
AES on the SDI outputs.

Controlling and monitoring of the signals that are
passing through the HFS-975 are displayed on a
front panel VFD. Providing instant operator control
from the local control panel which allows for easy
manipulation of video and audio signals.

Operational modes for numerous applications are
user-selected: The user has the choice of
processing any input to any output, A to D, D to A,
up, down or cross-conversion, and processing.
Any input can be switched to all standard and high
definition outputs.

Since analog video will be a requirement for
awhile, the HFS-975 fulfills those requirements for
all applications. Analog video CAV and Y/C are
also supported. Firmware is easily updated as the
requirements occurs. Ethernet is a future addition
to the HFS-975.
