A plane publication product supports transmit-receive of a multimedia information signal of an interactive interconnected system comprising an electronic reading device and an electronic transmitter-receiver. A sheet surface of the plane publication product may be attached with an information content. The multimedia information signal is synthesized by media information data and associated data; 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; and the electronic transmitter-receiver is configured to control transmit-receive of the associated data of the decomposed multimedia information signal, receive the associated data decomposed by the transmission circuit of the electronic reading device, transmit the associated data to external via a remote wireless technology, and quickly call out an associated electronic file.
