The DP572 Dolby^® E Decoder is designed to ease the transition by DTV broadcasters and program producers from two-channel to multichannel audio. The DP572 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 is easily integrated into postproduction and broadcast facilities. The DP572 can accept both PCM and Dolby E signals and can switch automatically to provide seamless integration of multichannel and archived stereo programming.
