Abstract
PURPOSE: To obtain an accurate request picture by providing a means, which generates a completion signal and sends completion information to the center after recording video information sent from the center, in a terminal.
CONSTITUTION: An address signal defined for a terminal is superposed to the requst picture signal sent from the center according to the request from the terminal, and they are supplied to recording signal processing circuit 34 and address signal sampling circuit 35. When the address singal sampled by circuit 35 and the address signal of the terminal agree with each other, gate circuit 36 is operated to operate erase circuit 38, and data is recorded on magnetic sheet 40 by the magnetic head. After recording completion, switch 41 is switched to reproducing side PB, and reproducing signal processing circuit 43 is operated after amplification in 42. Circuit 43 operates reproducing discrimination circuit 44 to discriminate whether the reproduced picture is correct or not. In case of a correct reproduced picture, a request picture stop command signal is sent to the center through video signal switching circuit 44. Otherwise, address singnals are subjected to sampling to repeat the same operation and perform discrimination until a correct reproduced picture is obtained.
