PROBLEM TO BE SOLVED: To share the same memory by storing digital picture data in a first storage means, storing graphic processing picture data in a second storage means, time-divisionally selecting either the first storage means or the second storage means and storing it in the memory. SOLUTION: An image input is digitized by an A/D converter 23 and it is encoded in a dynamic image encoder 25 by using an image memory 24. BCH data for error correction are added by a BCH 26 and it is sent to multimedia multiplex separator. When a BCH 29 receives video data from multimedia multiplex separator, the BCH 29 corrects the error and data are decoded in a dynamic image decoder 28. Decoded data are written into an image memory 30 through an MUSX 31 and a CRT controller 32 generates a graphic and writes graphic data into the image memory 30 through the MUX 31. Writing and reading control is executed in time division. |
