Abstract
PURPOSE: To perform multi-address still picture services during an individual still- picture service by a superimposing circuit provided to each circuit, by additionally providing frame memories for services of a multi-address still picture to a center.
CONSTITUTION: After passing through switching unit 2, a control signal from terminal equipment 13 is received by receiver 3 and converted into a digital signal, which is sent to control unit 4. In controller 4, the signal is analyzed and a still picture presented to terminal equipment 13 is extracted by still-picture information file 6 and character generator 5 and stored temporarily in one of frame memories 8 to 9 by way of video distributing coupler 7 before being sent out. On the other hand, center 1 needs to transmit the same information to all terminals simultaneously, control unit 4 stores the information temporarily from character generator 5 into memory 10, whose read outputs are applied to superimposing circuits 11 and 12 for superimposition.
