DDP84 - Dolby Digital and Dolby Digital Plus encoder with Dolby E decoder
Description
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 DDP84 includes a Dolby E decoder. This enables the decoding of Dolby E and encoding that into Dolby Digital (plus) with only one Synapse card.
The calculation power of the DDP14/84 make a simultaneous encoding of 4 individual stereo channels (languages) to 4 Dolby Digital (Plus) 2.0 streams possible.
