HPD130 - HD, SD embedded domain PCM + AD to Dolby Digital (Plus) encoder with audio shuffler and audio description processor (3Gb/s upgradeab

Description

The HPD130 is an embedded domain PCM to Dolby Digital or Dolby Digital Plus encoders with fully routable Audio Description processor. This processor uses a stereo track as main program (input 1-2 of the AD processor) and mixes the AD track triggered by the mix enable track (input 3-4 of the AD processor).

The output of the AD processor can be routed to any of the Dolby digital encoder inputs or any of the normal PCM channels of the 16 channel embedder.

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 G/HPD100 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 HPD130 can be future upgraded to GPD130. This allows for staged implementation of HD infrastructures and spread the cost over multiple budget years.
