Dolby DP579

The DP579 Dolby® E Tri-Level Sync Interface allows high-quality Dolby E multichannel audio and metadata to be stored on 24-frame systems using existing DP571 and DP572 Dolby E encoders and decoders. Applications include postproduction for DTV, electronic cinema, telecine, and archiving.

The DP579 converts tri-level video sync into Dolby Black, a video reference signal specifically for use with existing Dolby E equipment. The DP579 enables a pair of Dolby E codecs (DP571 Dolby E Encoder/DP572 Dolby E Decoder) to operate at 23.98, 24, and 30 fps from a tri-level reference, in addition to 25 and 29.97 fps. The DP579 also accepts traditional NTSC and PAL reference signals and passes them through unchanged.
