<p>A moving picture coding apparatus is disclosed in which when an input image and the image of the preceding image are correlated to each other, the inter-frame coding is effected, while when no correlation exists, the intra-frame coding is carried out for packet switched networks. The moving picture coding apparatus is comprised of a device (36) for refreshing blocks in a frame at regular intervals of time, and when the number of cells generated by coding during a predetermined past time is larger than a threshold level set in advance, the number of blocks refreshed is reduced, thereby preventing the image information more than a maximum transmission capacity of the packet switched networks from being generated. <IMAGE></p> |
