Abstract
For distributing a user image corresponding to the user position in a virtual space, the invention provides a method of fetching the user image taken with a video camera into the main body of a computer (S), judging the user position in the virtual space (S), setting a large quantization coefficient in case of an office view (S) but setting a small quantization coefficient and an even smaller quantization coefficients for a face area in other cases (S), then compression encoding the image data with the designated quantization coefficient ((S) and transferring the image data to a host server apparatusthrough a network (S). The user terminal receives images of other users from the host server apparatus (S), expands the image data (S) and displays the image data on a display apparatus(S).
