摘要： An apparatus, system, method and computer program product for providing broadcast services. A terminal controller is configured to use data forming the whole of or part of an electronic service guide, and store information concerning the accessibility of services. That information is then used to generate a list of selectable services available to the user. A user interface presents at least part of the list in a selectable manner. Service accessibility display options are included either as a setting in the terminal or as a user input. Subscribed services are presented to the user differently than non-subscribed services. If a non-subscribed service is selected, payment data is retrieved from the terminal and a suitable subscription is purchased without significant user involvement. The purchase of a subscription results in the terminal receiving subscription data, which is then stored for future use.

摘要： Content items or portions of content items are made available for previewing according to various techniques. In some techniques, designated portions of content items are transmitted in plaintext, while the remaining portions are transmitted in encrypted form. In other techniques, an entire content item is transmitted in encrypted form. However, content keys for decrypting the content item may be transmitted in plaintext form for certain portions designated for previewing and in encrypted form for the remaining portions. Also, an entire content item may be transmitted in encrypted form. Similarly the content keys for decrypting the content item is transmitted in encrypted form. However, preview rights keys for decrypting the content keys may be transmitted. These rights keys have associated usage rules that limit their use.
