Abstract: A user playing a media file having ads on a playback device is able to automatically skip the ads during playback depending on the user's subscription level, as indicated in a user license or user account information. Whether an ad is automatically skipped may depend not only on the user license but also on attributes of the ad. An ad may have a skip-level which indicates the “importance” of the ad. If the advertiser wants to ensure that the ad will be seen and not be automatically skipped by a media playback unit, it can pay a higher price for the ad and the ad will be assigned a higher skip-level value. On the user subscription side, a user who wants to avoid ads may pay a higher subscription fee and have a user license that determines, via an auto-skip level value (“user level”), how many ads the user can automatically skip during playback of the media file. With a higher the auto-skip level value, the user is able to automatically skip more ads on the playback device.

Abstract translation: 在播放设备上播放具有广告的媒体文件的用户能够根据用户的订阅级别在用户许可证或用户帐户信息中指示的情况下自动跳过播放期间的广告。 广告是否自动跳过可能不仅取决于用户许可，还可能取决于广告的属性。 广告可能有一个跳过级别，表示广告的“重要性”。 如果广告客户希望确保广告被看到，并且不会被媒体播放单元自动跳过，则可以为广告支付更高的价格，并且广告将被分配更高的跳过级别值。 在用户订阅方面，希望避免广告的用户可能会支付更高的订阅费用，并具有通过自动跳过级别值（“用户级别”）确定用户可以自动跳过的广告数量的用户许可证 播放媒体文件。 自动跳过级别值越高，用户就可以自动跳过播放设备上的更多广告。

Abstract: A method and apparatus for a digital broadcasting service may allow direct and real-time control of a digital broadcasting receiver. A service providing server inserts a content control access criteria descriptor into a transport stream and transmits content and the content control access criteria descriptor to the receiver through the transport stream. The receiver receives the transport stream and processes the content according to the content control access criteria descriptor, which can contain lock control information and coupon provision information. The lock control information indicates whether a control function of the receiver is locked or unlocked for specific content. The coupon provision information indicates whether a coupon available for the purchase of pay content is granted depending on execution of specific content.
