The DP571 Dolby® E Encoder eases the transition from two-channel to multichannel audio for DTV broadcasters and program producers. It enables the distribution of up to eight channels of high-quality audio plus Dolby Digital metadata via a single AES3 pair on two audio tracks of a digital videotape, digital audiotape, video server, or two-channel distribution systems.
The DP571 performs Dolby E audio coding, developed specifically for the production, contribution, and distribution of multichannel audio. This is distinct from audio encoded with Dolby Digital, which is used for final transmission of multichannel programs directly to the home viewer.
