摘要： A dynamic repository (either storing digital data content or pointers to stored digital data content) works in conjunction with a plurality of interfaces to manage digital content and digital rights policies associated with one or more users. Digital rights policies are unique to each user and such policies define access to digital content in the repository. The user's digital rights policy indicates the level of access a user has to digital content in the repository (e.g., the policy could indicate that the user has authorized access to a particular file for a period of seven days). The interfaces linked with the content repository are used to access and manipulate the digital data content (based upon each user's digital rights policy) and the digital rights policies stored in the content repository. The interfaces include: (a) one or more authentication interfaces for authenticating users, (b) one or more digital rights management (DRM) interfaces allowing users to add, delete, or edit the digital rights policies, (c) one or more data access interfaces allowing users to selectively access digital data content as defined by their individual digital rights policy, (d) one or more browsing interfaces allowing users to selectively browse said digital data content, or a (e) one or more content manipulation interfaces allowing said users to add, delete, or edit said digital data content.
摘要翻译：动态存储库（存储数字数据内容或指向存储的数字数据内容的指针）与多个接口一起工作以管理与一个或多个用户相关联的数字内容和数字权限策略。数字权限策略对于每个用户是唯一的，并且这样的策略定义对存储库中的数字内容的访问。用户的数字权限策略指示用户对存储库中的数字内容的访问级别（例如，策略可以指示用户已经授权访问特定文件七天）。与内容存储库链接的接口用于访问和操纵数字数据内容（基于每个用户的数字权限策略）以及存储在内容存储库中的数字权限策略。接口包括：（a）用于认证用户的一个或多个认证接口，（b）允许用户添加，删除或编辑数字权利策略的一个或多个数字版权管理（DRM）接口，（c）一个或多个数据访问接口，允许用户选择性地访问由其个人数字版权保护策略定义的数字数据内容，（d）允许用户选择性地浏览所述数字数据内容的一个或多个浏览界面，或（e）一个或多个内容操纵界面，用户添加，删除或编辑所述数字数据内容。

摘要： A satellite transponder switch (STS) maintains a table that maps set-top boxes (STBs) to carrier frequencies. The STS receives a first request from a first STB for a first transponder band and a second request from a second STB for a second transponder band. The STS accesses a first satellite feed and polarity based on the first request, and a second satellite feed and polarity based on the second request. The STS band-pass filters the first and second transponder bands from the first and second satellite feed and polarity, respectively. The STS frequency shifts the first transponder band to a first carrier frequency assigned to the first STB and the second transponder band to a second carrier frequency assigned to the second STB. The STS outputs a signal that comprises the frequency-shifted first and second transponder bands to the first STB and the second STB.
摘要翻译：卫星转发器交换机（STS）维护一个将机顶盒（STB）映射到载波频率的表格。 STS从第一STB接收第一应答器频带的第一请求和来自第二STB的用于第二应答器频带的第二请求。 STS基于第一请求访问第一卫星馈送和极性，并且基于第二请求访问第二卫星馈送和极性。 STS带通分别从第一和第二卫星馈送和极性滤波第一和第二应答器频带。 STS频率将第一应答器频带移动到分配给第一STB和第二应答器频带的第一载波频率到分配给第二STB的第二载波频率。 STS将包括频移的第一和第二应答器频带的信号输出到第一STB和第二STB。

摘要： A system and method of processing a satellite signal is disclosed. In a particular embodiment, the method includes receiving a satellite signal at a receiver, where the satellite signal includes a Moving Picture Experts Group (MPEG) portion and a radio frequency (RF) portion. The method also includes decoding the satellite signal to produce a digital MPEG transport stream signal that includes the MPEG portion, by removing the RF portion from the satellite signal without substantially altering the MPEG portion. The method also includes transmitting the digital MPEG transport stream signal to a vestigial sideband (VSB) modulator, where the VSB modulator transmodulates the digital MPEG transport stream signal to a VSB signal.
