A multimedium terminal apparatus which can simultaneously communicate with maximum N (N: integer of 2 or larger) terminals through a plurality of lines comprises: a plurality of separating circuits, connected to the lines, for respectively extracting the image data of 1/N-reduction picture plane which has been coded by using L/N unit regions among L (L: value which is integer times as large as the value of N) unit regions forming one picture plane of a predetermined full size; and a display position control circuit for changing position designation information of the unit regions included in the image data in a manner such that up to N 1/N-reduction picture planes can be enclosed in one picture plane of a predetermined full size. When images are simultaneously mutually communicated among multipoints, such a communication can be realized by merely preparing one image decoding unit although the decoding units of the number which is equal to only the number of terminals which simultaneously communicate must have been prepared in the conventional case.

[ What is claimed is:] [1.] A data processing apparatus comprising:a) input means for inputting image data from a maximum N (N is an integer of 2 or larger) terminals through a plurality of lines, wherein said input means inputs an image plane of a predetermined size which is block-coded by using L/

[ What is claimed is:] [1.] A data processing apparatus comprising:a) input means for inputting image data from a maximum N (N is an integer of 2 or larger) terminals through a plurality of lines, wherein said input means inputs an image plane of a predetermined size which is block-coded by using L/N blocks (L is a value which is an integral number of times as large as the value of N, L.noteq.N), from each terminal, wherein an image plane of the predetermined size comprises data of L blocks, and wherein one block comprises a plurality of pixel data; andb) control means for controlling a display position when the block-coded data input by said input means is displayed in the image plane of the predetermined sizes, wherein head data which corresponds to the display position controlled when the coded data is displayed is added to the coded data from each terminal and said control means controls the display position of the coded data from each terminal by changing the head data.
