摘要

An arrangement and method is disclosed for transmitting data items to a receiver for selective display on said receiver. The data items may collectively constitute an electronic television program guide or a database of products and services for electronic shopping purposes. By transmitting auxiliary presentation and navigation information, the information provider may determine how a receiver displays the data items and how the receiver needs to respond to user actions. Sometimes, however, it is desirable for a receiver to respond in a setmaker-defined manner, even if navigation and presentation data are provided by the setmaker. In order to solve possible conflicts between the information provider's interests and the setmaker industries' interests, the transmission includes a copyright bit which allows an information provider to indicate explicitly whether or not a receiver is allowed to ignore the transmitted presentation and/or navigation data.
