Digital Stereo Sound with Terrestrial Television
The BBC is developing a digital system that will carry two high-quality sound signals with existing System IUHF television transmissions. The system uses a second sound carrier that is spaced at about 6.5 MHz above the vision carrier and four-phase differential phase-shift keying (DPSK) modulated at a bit rate of about 700 kbit/sec. Over-air and laboratory tests proved the ruggedness and compatibility of the system and led to a detailed specification which is now under discussion. Experiments in stereo program production have been conducted in anticipation of a full broadcast stereo service.
