    Abstract: A method and system for media consumption are described. The method including tagging each one of a plurality of content items with at least one metadata tag, the metadata tag including a descriptor of at least one topical attribute describing the content item, the plurality of content items being adapted for consumption on a plurality of user devices, wherein the plurality of content items are provided in multiple file formats; acquiring a history of user consumption of the plurality of content items on a plurality of user devices associated with a single user; storing a user record including the acquired user history, a plurality of metadata tags associated with user consumed content, and including a list of devices comprising the plurality of user devices associated with a single user; building a playlist based, at least in part, on the following criteria, wherein each content item which is listed on the playlist has at least one tag which is also one of a plurality of tags already stored in the user record: a) including a content item which has been started but not completely consumed, b) not including content items marked in the acquired history as being completely consumed, unless the content items have changed with respect to the version consumed, and c) including content items which have not been consumed; selecting at least one content item from the playlist; and pushing the selected at least one content item to at least one of the plurality of user devices associated with a single user, wherein if the selected at least one content item is not suitable for consumption on the at least one of the plurality of user devices, then a next item in the playlist is pushed to the least one of the plurality of user devices.

    Abstract translation: 描述了用于媒体消费的方法和系统。 所述方法包括使用至少一个元数据标签来标记多个内容项中的每一个，所述元数据标签包括描述所述内容项的至少一个主题属性的描述符，所述多个内容项适于在多个用户上消费 设备，其中所述多个内容项目以多种文件格式提供; 在与单个用户相关联的多个用户设备上获取所述多个内容项目的用户消费历史; 存储包括所获取的用户历史的用户记录，与用户消费内容相关联的多个元数据标签，并且包括与单个用户相关联的包括所述多个用户设备的设备列表; 至少部分地基于以下标准构建播放列表，其中在播放列表中列出的每个内容项目具有至少一个标签，其也已经存储在用户记录中的多个标签之一：a）包括 已经开始但未完全消费的内容项目，b）不包括所获取的历史中标记为被完全消费的内容项目，除非内容项目相对于所消费的版本已经改变，以及c）包括尚未被使用的内容项目 消耗 从所述播放列表中选择至少一个内容项; 以及将所选择的至少一个内容项目推送到与单个用户相关联的所述多个用户设备中的至少一个，其中如果所选择的至少一个内容项目不适于在所述多个用户设备中的所述至少一个用户设备 ，则播放列表中的下一个项目被推送到多个用户设备中的至少一个。

    Abstract: In one embodiment a method, apparatus and system for is described for receiving a first input including a first decryption key and a second input including an encrypted second decryption key at a cryptographic decryption apparatus, the encrypted second decryption key to be decrypted by the cryptographic apparatus according to the first decryption key, storing a value of a key ladder length in a first register by a cryptographic processor, and using the stored value as a loop index by the cryptographic processor for a number of iterations of the cryptographic decryption apparatus executed as a loop, wherein at one stage in the loop execution of the cryptographic decryption apparatus, the second input includes the key ladder length, wherein the loop operation of the cryptographic decryption apparatus operates for a number of iterations equal to an initial value of the loop index. Related methods, apparatuses and systems are also described.
