Abstract

PURPOSE:To decrease the number of video recording and reproducing devices at an image center by previously transmitting all video-recorded columns from the image center to an exchange, and then selecting a column requested by a subscriber at the exchange. CONSTITUTION:When the reproduction period of a VTRRPj passes, connection with one of receivers, e.g. RECj is made and a new column is recorded on a VTR tape in the VTRRPj. Then, reproduction outputs of M' units of VTRRPj and those of M units of receivers RECi are all transmitted to an exchange by a transmitter TR. The TR outputs information, multiplexed corresponding to the capacity of a repeating transmission line TRL, by using an (M+M')-number of channels. In a subscribers house, on the other hand, a subscriber controller CNTa and a subscriber monitor device MONa are installed; a desired column is selectively reproduced by an input command from the CNTa and displayed on the MONa. In this constitution, the number of VTRs is proportional to that of programs and is independent of the number of subscribers, so the number of VTRs at an image center is reduced.
