Features Dolby Laboratories, with Dolby Digital Plus, is targeting at the next generation of digital transmission and optical formats. The advantage of Dolby Digital Plus is a channel count of up to 7.1 (13.1 in the future) and bit rates of about 50 percent of normal Dolby Digital.

An important application is the transcoding of normal Dolby Digital to Dolby Digital plus for cable head-ends. This gives a data rate reduction of 50% for the audio path.

The calculation power of the DDP14 make a simultaneous encoding of 4 individual stereo channels (languages) to 4 Dolby Digital (Plus) 2.0 streams possible.

The DDP14 is a stand alone or Synapse ADD-ON Dolby Digital (Plus) encoder. They will support the following encoding algorithms:

        

Up to 4 times 2.0 Dolby Digital (Plus) outputs.

5.1 Dolby Digital (Plus) and + 2.0 Dolby Digital (Plus) Individual offset delay per input Individual gain control per input (except bitstream input) Able to handle all AES/EBU input formats Full audio channel shuffling Ability to use the Synapse ADD-ON bus for in- and output purposes.

Locks to Black & Burst, AES input or Mastercard Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18 frame and the Ethernet port (ACP)

Complementary cards:



All cards with embedding and de-embedding functions with the original ADD-ON audio bus

Applications   

Multi channel encoding of Dolby Digital (plus) Transcoding of Dolby Digital to Dolby Digital Plus Multi language encoding, 4 x stereo Dolby Digital (Plus)
