Digital switching signal sequence for switching purposes, apparatus for including said digital switching signal sequence in a digital audio information signal, and apparatus for receiving the information signal provided with the switching signal sequence

摘要

A digital switching signal sequence is realized as a previously digitized, high-pass filtered white noise signal of a predetermined length T, with a high-pass cut-off frequency which lies above the frequency where the loudness threshold characteristic in silence of the human hearing has its highest sensitivity, if possible. The switching signal sequence is employed for switching purposes (206), e.g., for switching between two information signals (201, 207).
