Video Processing Frame Sync Modules Overview
The 7555 HD/SD, 9550 3G/HD/SD, and 9550-XA 3G/HD/SD video processing frame sync modules are
used for processing, synchronizing and timing 3 Gb/s or 1.5 Gb/s high definition video or standard
definition video signals. They share the same essential functions, with a couple of key differences.
These differences have to do with the type of video signal accepted (HD versus 3G), the number
of BNC ports available for digital audio, and the number of BNC ports available for SDI video signal
output.
Shared Functionality
All three modules can do video processing. All three have frame synchronizing functionality. Both the
7555 and 9550 have one SDI input, one reference input, four SDI outputs, and four AES I/O ports.
Shared Options
All three modules share the following set of options that extend their capabilities with software keys:
•
7615 Dolby™ E, Dolby D/AC-3 Decoder sub module and software key option
•
7630 Dolby E Encoder sub module and software key option
•
7635 Dolby D/AC-3 Encoder sub module and software key option
•
9615 AES, analog audio, and data I/O software key option
•
9670 LevelTrack™ Audio Loudness Control AGC software key option
•
9690 Audio Compliance and Monitoring software key option
Key Differences
The 7555 accepts a 1.5 Gb/s high definition or standard definition video signal. The 9550 has the
additional capability of accepting a 3 Gb/s high definition video signal.
The 9550-XA option adds two AES I/O ports (for a total of six rather than four), and removes two SDI
outputs (for a total of two rather than four).
Flexible Synchronization
An adjustable timing system genlocks to house reference. The modules genlock to either composite
video (PAL or NTSC) or to HD Tri-Level Sync. The modules can lock to the frame’s master reference or
reference can be connected directly to the modules’ external reference BNC. The serial output timing
can be set anywhere within a frame of the selected input reference.
Upon loss of signal, the modules provide freeze frame or black until the signal is recovered. In freeze
mode, audio can be muted or passed.
Uncompressed Bandwidth
The 3G, HD or SD SDI input is carried at full, uncompressed bandwidth throughout the entire module.
