Moving picture coding apparatus and TV phone using the same

A TV phone which comprises:

• a voice input for receiving voice data;
• a voice coder for coding said voice data;
• a moving picture input for receiving moving picture data;
• a pen input for receiving handwritten image data;
• a moving picture coding apparatus which comprises:
• a combining circuit for combining said moving picture data and said handwritten image data and for outputting a combined image;
• and
• a motion compensative moving picture coding circuit for coding said moving picture data and a newly added part of said handwritten image data;
• and
• a multiplexer for multiplexing said coding voice data output from said voice coder and an output from said moving picture coding apparatus, wherein
• said combining circuit outputs, toward said motion compensative moving picture coding circuit, coding region information which indicates that a region coded before a latest frame of said handwritten image is a non-coding region and that said moving picture is a coding region;
• and
• said motion compensative moving picture coding circuit codes said combined image on the basis of said coding region information.
