In addition, Dolby staff will show six previously-released pro audio units and will host two discussions on multichannel audio in digital television broadcasting.Dolby is debuting the following products at the show:24P Dolby E Coding TechnologyPost-production is migrating towards 24-frame acquisition and storage to maintain high quality across multiple delivery formats. To generate 23.98 or 24 fps Dolby E streams, the new DP579 Dolby E Tri-Level Sync Interface converts standard tri-level video sync into a Dolby Black reference (similar to standard black burst reference) for use with the DP571 and DP572 Dolby E encoder and decoder. A required software upgrade for the DP571 and DP572 will be available for all registered units at no charge. The DP579 will be available this fall.DP583 Dolby E And Dolby Digital Frame SynchronizerBroadcast, cable, and satellite industries need to synchronize externally generated Dolby E or Dolby Digital bit streams to match the internal plant timing. The DP583 accepts all Dolby E and Dolby Digital frame and data rates, as well as PCM inputs, and provides an output that has been reframed to match local plant reference. The DP583 also allows post-production facilities to record Dolby E streams to non-video formats, such as DAT. The DP583 will be available this fall.DP569 Dolby Digital Encoder With Version 2.0 SoftwareNew features include an improved menu system, a Dolby Digital Surround EXô flag, additional down-mixing settings, new compression profiles and presets, automatic data rate selection, a delay word for multiplexers, and improvements in audio coding quality.
