摘要： Various technologies and techniques are disclosed that relate to providing interactive television by synchronizing content to live and/or recorded television shows. Content is synchronized without the use of in-band triggers. A broadcast stream is received, and search/action pairs are received from a transmission path, such as from the Internet or user. When the search criteria are found in the broadcast stream, the associated action is performed and the content is synchronized with the show. An application programming interface is used to facilitate synchronization, and includes a set search method, a search function template method, and a clear search method. The set search method initiates searching of the broadcast stream and registers one or more callback methods for performing the associated action when the match is found. The search function template serves as the template for registering the callback methods. The clear search method clears the system resources from the search.

摘要： Innovative techniques for identifying and distinguishing content, such as commercials, can be used with means for marking key frames within the commercials to facilitate replacement of commercials and other programming segments in such a way as to provide improved focus and relevance for targeted advertising based on known and/or dynamic conditions. The identification of commercial features can also be used to provide improved trick play functionality while the commercial or other programming is rendered.

摘要： A transport stream is encrypted in such a manner that the stream may be processed without requiring encrypted portions of the stream to be decrypted. Thus, an analysis is performed on the stream to determine at least one portion of the stream that is to pass unencrypted, thus enabling the stream to be processed in a manner that bypasses encrypted portions of the stream.
摘要翻译： 传输流被加密，使得流可以被处理而不需要对流的加密部分进行解密。 因此，对该流执行分析，以确定流未经加密的流的至少一部分，从而能够以绕过该流的加密部分的方式处理该流。

摘要： The present invention enforces digital rights within the confines of a content license by validating an entity certificate. Cryptographic information within a entity certificate is utilized to unlock protected content and authenticate the entity certificate. The entity certificate includes personal credentials, which have information that the entity is unwilling or uncomfortable to share publicly. For example, the personal credentials may include private information, or information associated with a personal object that cannot consume the protected content, or both.
摘要翻译： 本发明通过验证实体证书来执行内容许可的范围内的数字权限。 利用实体证书中的密码信息来解锁受保护的内容并认证实体证书。 实体证书包括个人凭证，其具有实体不愿意或不舒服地公开分享的信息。 例如，个人凭证可以包括私人信息或与不能消费受保护内容的个人对象相关联的信息，或两者。
