Abstract
A picture information transmission system enciphers and transmits picture information after interframe coding so that a receiving apparatus which does not have a cipher decoding device can decode and display the picture at an arbitrary time to allow potential customers to view the image for advertising purposes. The system is constructed so that coding is stopped for a predetermined period of time, and for one of a plurality of regions of each frame within the period, data are successively coded by intraframe coding before the data are outputted.
