The invention relates to an information association technology supporting a cross-media product, in particular to an audio information signal supporting an interactive interconnected system. The signal is formed by audio data and associated data synthesis. The interactive interconnected system comprises an electronic reading device and an electronic transmitter-receiver. The associated data is a preset Uniform Resource Identifier. The electronic transmitter-receiver is provided with an associated data reception circuit, an associated data transmission circuit and a central processing unit (with memory). The associated data reception circuit is equipped with a short-distance signal transmission-reception circuit. The electronic transmitter-receiver is mainly configured to control transmit-receive of the associated data of a decomposed multimedia information signal, receive the associated data decomposed by a transmission circuit of the electronic reading device, transmit the associated data to an external information data storage center via a remote wireless technology, and quickly call out an associated electronic file.
