Tiering and addressability are not new concepts to the cable television industry. However, the application of these concepts to full field teletext presents an exciting new service which can be offered. The ability to subscribe to specific categories out of a large, instantly available, data base is both technically feasible and affordable. The capability of full field tiered, addressable, and scrambled teletext to offer a profitable service today is further enhanced by future expansion possibilities into the areas of two-way interactive services, home games and computers.
