Information communication system.

摘要

In this information transmission system, a PCM encoder (42) is provided for time-division multiplexing multichannel audio signals (S2, S3) and a digital character information signal (S4) to generate a time-division multiplexed, or TDM, information signal (S5). The TDM information signal is angle-modulated by the modulator (44) to generate an angle-modulated information signal (S6). This signal (S6) is supplied to a frequency-division multiplexer (40), which multiplexes the angle-modulated information signal (S6) and an image signal (S1) so as to generate a frequency-division multiplexed, or FDM, information signal (S7) wich is adapted to be supplied to a certain subscriber.
