Digital data of a plurality of video/audio softs is stored in a plurality of random-accessible large capacity storage device (9) and a control device (8) designates the reading of the video/audio softs and a vacant channel number to decoder devices of a multi-channel output, so that the designated video/audio softs are intermittently read out by time division from the large capacity storage devices every predetermined blocks by the decoder devices to be temporarily stored and thereafter decoded and outputted from the designated number channels, and thus, any soft can be supplied to the terminal devices at any supply starting time, irrespective of whether the requested softs are the same or different, so long as the number of the output channels of the data processing device is within the permissible range. The softs can be supplied to a number of terminal devices of which the number is beyond the number of the prepared softs, and even when the requests are concentrated to a specific soft, the access of the soft can be performed in a short time without increasing the waiting time, and it may be sufficient to merely prepare a small capacity memory in the decoder devices, so that the cost of the decoder devices can be reduced.
