This invention enables Scanable Icons, which may be predetermined graphical images, and similar encoded information to be applied to video systems in a manner that is user-friendly and brings many of the advantages of easy information access and management to the video environment. The optical path normally required when using such encoded information is avoided. Supplementary information, including more details for advertisements, is provided in a non-invasive manner, allowing the user to access the supplementary information at convenient times and locations. The Scanable Icon adds a symbol to the existing advertisement without increasing its duration. Advertising is made substantially more effective for the advertiser and more useful for the consumer.
