HD / SD SDI Frame Synchronizer
Video frame synchronizer for all standard and high-denition SDI signals.
The SFS-8221 is a HD / SD SDI frame synchronizer
designed for re-timing applications in both standard and
high-denition environments.
The SFS-8221 supports all popular standard and high-denition
video formats including 480i, 576i, 720p, 1080i. The format of
incoming video is automatically detected, simplifying system setup.
The SFS-8221 accepts an SDI signal of either standard (270Mb/s)
or high-denition (1.485Gb/s), automatically equalizing for cable
loss and providing a reclocked SDI output. The video is then
synchronized to either a frame-wide reference or a local reference.
A delay mode is also available for adding xed delay to the
incoming video.
openGear
®
frames support a distributed frame reference, allowing
a single incoming reference sync signal to feed timing information
to all modules in a frame. Thus, a single composite or tri-level sync
signal can be used for multiple frame synchronizers. Alternatively,
each frame synchronizer accepts an additional local reference
signal to provide additional system timing exibility.
Ancillary data (VANC) is protected, and is passed from input to
output, ensuring data is not lost during the frame sync operation.
Video proc amp and full timing controls are provided.
