4. The GED100 Card
Introduction
The GED100 is an embedded domain Dolby E to Dolby Digital or Dolby Digital (Plus) transcoder. It
enables simultaneous encoding of 5.1+2.0 or 4 individual stereo channels (languages) to 4 Dolby Digital
(Plus) 2.0 streams.
The new Quad Speed audio bus allows for implementation of ‘in between’ audio processing. This means
that we can stream the decoded Dolby E audio to a Quad Speed Audio ADD-ON card such as the DLA44
or DLA42, process this audio and send it back to the GED100 for encoding into Dolby Digital or Dolby
Digital plus.
The ADD-ON card theoretically does not need a connector panel (besides the metadata input) and all
audio routing is performed inside the Synapse frame by just placing these cards in adjacent slots.
