A synchronising system for use with a plurality of digital signal reproducers (111 to 114) such as compact disc players, in which each signal reproducer includes a digital I/O modulator (1112), a digital I/O demodulator (1111) and a decoder (1110). The system includes a digital signal multiplexer (19) supplied with output signals (PBMD) from the digital signal reproducers (111 to 114) and which produces a frame synchronising signal and plural channels of digital signals. The digital signal multiplexer (19) includes a clock pulse (CLK) and word synchronising signal (SYN) generator (1900), a digital I/O modulator (1901) and a digital I/O demodulator (1910). The corresponding digital I/O modulator and digital I/O demodulator of each of the signal reproducers (111 to 114) and of the digital signal multiplexer (19) are coupled to each other so as to synchronise the digital reproducers (111 to 114). |
