HED100 - HD, SD embedded domain Dolby E to Dolby Digital (plus) transcoder with audio shuffler (3Gb/s upgradeable)

Description

The HED100 is a embedded domain Dolby E to Dolby Digital or Dolby Digital Plus transcoder . Simultaneous encoding of 5.1+2.0 or 4 individual stereo channels (languages) to 4 Dolby Digital (Plus) 2.0 streams is possible.  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 like the DLA44 or DLA42, process this audio and send it back to the HED100 for encoding into Dolby Digital or Dolby Digital plus.

The ADD-ON card does not need a connector panel and all audio routing is performed inside the Synapse frame by just placing these cards in adjacent slots. The HED100 can be future upgraded to GED100. This allows for staged implementation of HD infrastructures and spread the cost over multiple budget years.
