PURPOSE:To store each control memory with an address in a voice memory and a destination address and to broadcast different documents simultaneously by forming a terminal block consisting of an ADPCM composite circuit and a CPU with plural control memories for every terminal broadcasting device. CONSTITUTION:Plural terminal blocks 20a-20d are connected to the voice memory 44 of a sound document multiplex broadcasting system and a microcomputer 40 and a timing pulse generating circuit 50 are connected to the blocks 20a-20d. Further, the respective blocks 20a-20d are provided with ADPCM composite circuits 22a-22d, CPUs 26a-26d provided with terminal control memories 34a-1-34a-32 and 34d-1-34d-32, timing circuits 24a-24d, terminal broadcasting devices 32a-1-32a-32 and 32d-1-36d-32, etc. The CPUs 24a-24d of the respective blocks 20a-20d read addresses and destination address of broadcasting out of their own memories 44 in order at specific intervals of specific time difference to broadcast different documents simultaneously. |
