Abstract

PURPOSE: To enable the still picture service both for the terminal specific type and a plurality of terminal polling type, by providing the bus switch controllable with the program control from the processing unit between the frame memory unit and the exchanger.
CONSTITUTION: The input signal from the terminal input unit 2 is inputted to the processing unit 8 via the exchanger 3, and terminal input fetch unit 7, the processing unit 8 analyzes the input signal and determines the picture to be transmitted next with the program control, issues the search instruction, to the still picture file 6 and writes in the still picture for the still picture frame memory 5 corresponding to the said terminal. Further, the still picture is delivered to the terminal reception unit 1 via the bus switch 4 and the exchanger 3. In the bus switch 4, the cross point between the input video line 11 and the output video line 12 is program- controlled with the processing unit and the still picture service different in format can be made.
