7.4.1.1 Overview
The CE-a Video Compression Module (VCM) is a single card that can encode a
single video input. By default the basic card supports encoding SD MPEG-2 video
and MPEG-1 Layer II Audio. Video and audio encoding functionality is extended by
the purchase of feature licenses.

Notes: Up to 6 CE-a modules can be fitted in the unit, but limitations due to
operational temperature may apply.
If the appropriate licenses are available, up to 16 channel pairs of audio can
be encoded using the MPEG-1 Layer II algorithm, 6 audio channel pairs can
be encoded in Dolby Digital or 6 channel pairs in (HE-)AAC.
There is also an option to configure the unit to pass-thru pre-encoded Dolby Digital,
