摘要： A cache server includes a media serving engine that is capable of distributing media content. A cache engine is coupled to the media serving engine and capable of caching media content. A set of cache policies is accessible by the cache engine to define the operation of the cache engine. The cache server can be configured to operate as either a cache server or an origin server. The cache server also includes a data communication interface coupled to the cache engine and the media serving engine to allow the cache engine to receive media content across a network and to allow the media serving engine to distribute media content across the network. The cache policies include policies for distributing media content from the media server, policies for handling cache misses, and policies for prefetching media content.

摘要： An entertainment access system is provided that enables a user to request and receive status reports that present current information concerning a wide variety of items pertaining to the user's devices, entertainment content and usage rights in a standard, predictable and consistent manner that enhances rather than hinders the user experience. In some illustrative examples, the user can request the status report from one of his devices that is registered with the entertainment access system. The entertainment access system responds by collecting and formatting the status information so that is can be conveniently displayed or otherwise rendered on the registered device. For instance, if the request is received from a cell phone device, which generally has a relatively small screen, the information may be presented in a relatively abbreviated format. On the other hand, if the request is received from the user's personal computer, the information may be presented by the entertainment access system to the personal computer in a more detailed or entirely different format than when the information is to be presented to a cell phone device.

摘要： This document describes tools capable of managing advertising in the field of digital entertainment content. The tools may enable advertisers to know which advertisements are more effective or are more likely to be effective with all users, users having similar demographic profiles, or a particular user. The tools may do so by building and maintaining profiles for users. These profiles may include many users' interactions with various advertisements, demographic information for the users usable to compare users, explicitly selected preferences of users, users' implicit preferences based on what entertainment content they watch, and other information.

摘要： An active stream format is defined and adopted for a logical structure that encapsulates multiple data streams. The data streams may be of different media. The data of the data streams is partitioned into packets that are suitable for transmission over a transport medium. The packets may include error correcting information. The packets may also include clock licenses for dictating the advancement of a clock when the data streams are rendered. The format of ASF facilitates flexibility and choice of packet size and in specifying maximum bit rate at which data may be rendered. Error concealment strategies may be employed in the packetization of data to distribute portions of samples to multiple packets. Property information may be replicated and stored in separate packets to enhance its error tolerance. The format facilitates dynamic definition of media types and the packetization of data in such dynamically defined data types within the format.

摘要： The present invention provides for a digital rights management system with a centralized domain service capable of creating and managing membership criteria for joining a domain in accordance with business rules defined by a content owner. A domain identification is created that allows a content provider to uniquely bind content licenses to a domain. The content licenses include usage rights that define how content associated with the licenses may be consumed by one or more members of the domain. The centralized domain service can enforce digital rights by validating membership criteria including at least one of a domain proximity check for validating that a requestor is in close proximity to the domain, a total number of requestors, or the frequency that the requests have been made by various requestors to join the domain and unjoin from the domain.

摘要： This document describes tools capable of managing digital content from multiple content providers based on a user's identity. By so doing, the tools may free people from the limitations of their storage media and devices. The tools may perform these and other actions through an indirect relationship with users, such as when third-party content providers use the tools but provide their own direct interface with users.
