Direct Stream Transfer™

Philips’ proprietary technology for lossless 2:1 data reduction in digital recordings on SACD. DST is optimized for audio-type signals, allowing sufficient storage capacity for double the old CD standard of 74 stereo minutes. By incorporating DST into the SACD standard, it is possible to store two complete 74-minute versions of audio material so as to combine a stereo DSD track, and a 6-channel surround mix, plus other data, text, graphics, and video, all on the single, high-density DASD layer.
