The Dolby E Decoder DP572 decodes Dolby E–encoded program material for use in broadcast and postproduction facilities prior to final DTV and HDTV transmission.
Front of the Dolby E Decoder DP572
The Dolby® E Decoder DP572 was designed to ease the transition from two-channel to multichannel audio for DTV broadcasters and program producers. It decodes up to eight channels of high-quality audio, plus Dolby Digital metadata, from a Dolby E signal encoded on a single AES3 pair, external fiber, satellite link, digital videotape, digital audiotape, or from a video server.
It's easily integrated into your postproduction and broadcast facilities. The DP572 can accept both PCM and Dolby E signals, and it can switch automatically to provide seamless integration of multichannel and archived stereo programming.
Multichannel programming typically uses a "5.1 + 2" Dolby E configuration, with six of the eight channels carrying a 5.1 program and the other two an Lt/Rt (matrix surround-encoded) or stereo two-channel program. Alternate channel configurations are available for multilingual or other specialized applications.
The Dolby DP572 requires a standard video black reference signal. It can also be used in 24-frame applications when accompanied with the Dolby E Tri-Level Sync Interface DP579.
Dolby E provides the ability to carry up to eight channels of audio with metadata over existing stereo infrastructures.
Ensures that audio-follow-video edits are free of mutes, glitches, or other aberrations, so you can switch, route, and perform edits directly on the digital bitstream without decoding and reencoding
Provides up to eight channels and carries Dolby Digital metadata generated by the program’s producers for final delivery to the home viewer's Dolby Digital decoder
Lets you insert a voiceover into the decoded Dolby E program or insert local stereo audio without the need for additional equipment; automates switching between stereo and multichannel programming within a transmission chain
