PURPOSE:To reduce the equipment of a center device, and to shorten a processing time until the transmission of picture data by compressing the picture data to be stored in the center device. CONSTITUTION:The center station is equipped with a means 2 which stores CG(computer graphics) data including a CG model such as a polygon or a function, and the array of the set of view point and noticed view point coordinates. And also, this center station is equipped with data processing means 3-8 which prepare corresponding display data by each block by reading the CG data from the picture data storage means according to a request from an arbitrary terminal equipment, and processing the CG model included in the CG data by each block based on the set of the view point and noticed view point coordinates. operate an encoding for the data compression, and repeat the operation of transmitting the data to the terminal equipment in the order of the array of the sets of the plural view points and noticed view points. |
