<p>PURPOSE:To make it possible to use an audio service equipment in common by using two buffer memories and by shortening the holding time of either one. CONSTITUTION:To transfer sound information between master magnetic tape 1, and buffer memories 2 and 3, it is transferred to both buffer memories 2 and 3 firstly and after information for one service is transferred partially, it is transferred to only buffer memory 3. When the transfer to buffer memory 2 is completed, the sound information recorded in buffer memory 2 is regenerated at a normal speed to output circuit 5 by switch 4, thereby performing the service. After the transfer to buffer memory 3 is done, a service to a following new request is performed from buffer memory 3. At this time, since switch 4 makes a connection between beffer memory 3 and circuit 5, buffer memory 2 is made free and used for a request from any other circuit.</p> |
