7710XUC-HD HD Format Up/Down/Cross Converter
All the modules accept two groups of embedded audio on the input and re-embed them into the serial
video outputs. The "-AES4" versions also accept four external discrete unbalanced AES inputs and
provide four AES outputs with the same audio that is being embedded. In the case of the 7710XUDC-
AES4-HD, the four AES outputs with the same audio are embedded on the output SD video signals, since
they share one common audio processor. The 7710XUC-AES4-HD has a separate audio processor for
the four AES outputs.
The re-embedded audio normally has the appropriate delay added to compensate for video delay incurred
by the conversion process, thus avoiding the need for external de-embedding and re-embedding of audio.
An additional audio delay adjustment can also be made for lip sync correction.
The units also transfer the closed caption and time code information from input to output performing all
necessary HD-to-SD and SD-to-HD translation and time code recalculations.
The 7710XUC-HD and 7710XUC-AES4-HD occupies two card slots in the 3RU frame (7700FR-C), which
will hold up to fifteen 1-slot modules, or one slot in the 1RU frame (7701FR), which will hold up to three
modules.
The 7710XUDC-AES4-HD occupies three card slots in a 3RU frame (7700FR-C), which will hold up to
fifteen 1-slot modules.
The units also provide card edge LEDs to indicate signal present, Genlock present, and audio groups
present.
