1. DESCRIPTION
The V6334/D Digital Audio De-Multiplexer is a full broadcast specification de-multiplexer of audio data from
HD (High Definition) and SD (Standard Definition) SDI data streams. Two versions of the V6334 are
available, one with 4 AES outputs (V6334Q/D), and another with 8 AES outputs (V6334E/D). Although the
V6334 processes High Definition (HD) video signals, it is fully compatible with all other products in the
range in terms of form factor, power supply requirements and control interface. The V6334 is a 3U high
card that can be fitted into a V1606 rack or a V6011 '1-Box', from which it obtains its power and control.
There is also an audio multiplexer module, the V6333, which is fully compatible with the V6334.
A passive rear module is required for all signal interconnections. There are 3 types of rear module; a 4
unbalanced output (Single module width), an 8 unbalanced output (Double module width), and one offering
8 balanced outputs (Single module width).
The unit automatically detects the standard and format of the SD or HD input video and operates
accordingly.
The unit de-multiplexes audio from SDI video data stream according to SMPTE 272M (SD) and SMPTE
299M (HD). Audio channels from all of the available audio groups may be de-multiplexed and output from
the module. Unlike de-multiplexers from some other manufacturers the audio does not need to be
synchronous with the video into which it is to be embedded.
There are up to two SDI outputs, and one re-clocked versions of the SDI input. All ancillary data may be
optionally stripped off the SDI input signal before being outputted. The EDH is optionally regenerated on the
card for SD.
The unit is fully controllable over the DART remote control system.
