Abstract

System to mark audio visual signals using controlled identification data, and implemented by a coder and a decoder using a PC, able to perform an electronic processing of audio frequency signals to code and to decode text messages in the audio playing of speech and musical files. The system is based on a SW program specifically developed.
This system is a typical electronic product and properly an audiovisual electronic device utilised in the multimedia electronic devices.
