To transmit information of contents directing the presence of both a sound and an image by a simple method.

(1) 'Control parameters of the image' or 'operation control parameters of a recipient side of information' and 'parameters of components of the presence of the sound' are interlocked. (2) 'Sound data of components of presence' are extracted from 'original sound data' in advance and 'the signal processing burden on the information recipient side is reduced' by the simple method for 'numeral composition by the combination of the intensity values of two kinds of sound data files' to reproduce the presence.
