PURPOSE:To simplify the management of a video source and to reduce operational cost and material cost. CONSTITUTION:The video signal and voice signal of the video source reproduced by a reproducing machine 1 are sent to a multiplexing part 5 and an A/D converter part 2. The A/D converter part 2 digitizes the video signal and the voice signal from the reproducing machine 1 and sends them to a memory part 3-1. These video signal and voice signal are successively written in memory parts 3-1 to 3-m. The video signals voice signals read from the memory parts 3-1 to 3-m are respectively sent to D/A converter parts 4-1 to 4-m and converted to analog signals. The multiplexing part 5 multiplexes the video signals and the voice signals from the reproducing machine 1 and the D/A converter parts 4-1 to 4-m to respective channels and supplies them through home terminals 6-1 to 6-n to television receivers 7-1 to 7-n. |
