Described is a system and method whereby a person(s) viewing or experiencing a multimedia program displayed on a device such as a computer screen or television screen can interact with the program in viewing environments including but not limited to: Internet type connections, telecommunication (telephone, ISDN, ADSL), VSAT satellite, and other wire and wireless transmission including as well as video conferencing. The goal of the interaction is to provide a useful and minimally interruptive form of advertising, enacting the sale of a product or service or communicating information in a synchronized manner that may or may not relate to the media being played. The interaction can take the form of a follow up email containing a special offer or information, or the interaction can even prompt the person(s) to initiate a purchase process for a good or service being promoted in conjunction with the media program. In other embodiments, viewers may interact with a given program by means of a plurality of options that include but are not limited to selecting an icon or banner or pressing a button on a remote control. The resulting action sequence will then be initiated, be it a request for information, a purchase activity and so on. If it is a purchase action that is initiated, we have enhanced the method of existing protected media delivery systems to include special security features that are designed to reduce and eliminate copying of protected multimedia programs.
