System and method of two way audiovisual transmission of advertising messages in places of massive transportation and gathering

Through the system and method of the two way audiovisual transmission of messages, the audiovisual transmission of messages in means of massive transportation, waiting halls and places of gathering is accomplished, through the use of electronic-audiovisual equipment of up-to-date technology resulting in a superior output of audiovisual messages. Through this way the viewer ― interested party is given the ability to handle the equipment in order to receive information through a printout as well as the ability of direct transaction with the advertised party and communication with the centre of operating and processing data through a telephone line. The advantage of this invention is the direct transmission of messages from the centre of operating and processing data to the places of projection and the ability given to the interested party to communicate for whatever interests him/her from the messages displayed, through the previously mentioned system, either directly with the source (the instructor being advertised) or with the centre of operation and processing data which provides and coordinates the messages, as the equipment used makes the transmission of messages a two way transmission.
