摘要： Disclosed is a method for securely presenting content in a mobile station. The mobile station may have a smart module, a security agent, and an air interface for communicating with a content provider and with a remote content rights manager. The smart module stores content presentation units and has a proxy content rights manager for when the mobile station is unable to receive secure content keys from the remote content rights manager using the air interface. In the method, content presentation units are transferred from the remote rights manager to the smart module for storage. Secure content keys are requested from the smart module for allowing presentation of content requested while the mobile station is unable to communicate with the remote rights manager. The secure content keys are transferred, based on a stored content presentation unit, from the proxy content rights manager to the security agent for allowing content presentation.

摘要： Disclosed are apparatus and methods operable to distribute targeted content. Additionally, disclosed are corresponding apparatus and methods operable to selectively choose and cache selected ones from among the distributed targeted content, and to further choose ones from among the cached content to present on a device. In some aspects, selective caching of content may be based upon a match between predetermined content attribute information and predetermined profile information. Further, in some aspects, an indicator is operable to trigger the selective inclusion of one or more of the cached content in a presentation of other content, which may be based on a match between a desired content attribute associated with the indicator and the respective predetermined content attribute information of the cached content.

摘要： Disclosed is a method for securely presenting content in a mobile station. The mobile station may have a smart module, a security agent, and an air interface for communicating with a content provider and with a remote content rights manager. The smart module stores content presentation units and has a proxy content rights manager for when the mobile station is unable to receive secure content keys from the remote content rights manager using the air interface. In the method, content presentation units are transferred from the remote rights manager to the smart module for storage. Secure content keys are requested from the smart module for allowing presentation of content requested while the mobile station is unable to communicate with the remote rights manager. The secure content keys are transferred, based on a stored content presentation unit, from the proxy content rights manager to the security agent for allowing content presentation.

摘要： A user-generated content (UGC) mobile distribution system supports creation of a personalized and virtual UGC broadcast channel that can be selectively clipped and cached by filtering based inter alia on content descriptors of popularity and freshness. A broadcast service provider can further provide meta data categorization for filtering that is more objective than what is supplied by a posting user of UGC content items. A broadcast program guide enables mobile devices to schedule clip downloads. Popularity, which can be sorted by applicable demographic, represents a criterion (e.g., rating scores, number of views, quantity of online discussion, etc.) whether associated content item should be downloaded for subsequent accessibility by a user, enhancing filtering based upon user profile and genre. Freshness represents how recent the associated content was made available for download by the broadcast service provider. Popularity can also be used as weighting to sort a display of cached content items.

摘要： In one example, a device includes one or more processing units configured to send, via a network, a request to retrieve at least a portion of media content, wherein the media content conforms to dynamic adaptive streaming over HTTP (DASH), and wherein the request comprises a request that the at least portion be delivered according to a file delivery service, and, in response to the request, to receive streaming data for the at least portion of the media content in accordance with the file delivery service over the network. The device may prepopulate a browser cache with the received data, such that a browser can, in effect, stream data using the file delivery service. The device may initially retrieve data of the media content using unicast, until a switch point of the data received via the file delivery service is reached.
摘要翻译：在一个示例中，设备包括被配置为经由网络发送用于检索媒体内容的至少一部分的请求的一个或多个处理单元，其中所述媒体内容符合通过HTTP（DASH）的动态自适应流传输，并且其中请求包括根据文件传送服务传递至少部分的请求，并且响应于该请求，根据网络上的文件传送服务接收媒体内容的至少部分的流数据。设备可以预先填充具有接收到的数据的浏览器缓存，使得浏览器实际上可以使用文件传递服务流式传输数据。设备可以首先使用单播来检索媒体内容的数据，直到达到通过文件传送服务接收的数据的切换点。

摘要： Parents can desire to limit content viewable upon a mobile device and a universal integrated circuit card can be programmed to limit viewing upon the mobile device. A user completes a service request form that includes an allowable view threshold for content upon the mobile device. The request can transfer to a service provider, sometimes via a base station. A subscription manager can forward the threshold back to the mobile device and the mobile device can program the threshold upon secure storage. When content is received, it can be compared against the threshold and a determination can be made on if the content is allowable to view in light of the threshold.

摘要： Techniques for sending and receiving broadcast information are described. In an aspect, broadcast metadata may be generated for broadcast information and may include location and time criteria used by terminals to filter the broadcast information. Each location and time criterion may include (i) a location criterion given by a target location and a presence or absence requirement and (ii) a time criterion given by a time period in which the location criterion applies. A terminal may receive the broadcast metadata prior to or with the broadcast information, obtain location and time criteria from the broadcast metadata, and filter the broadcast information based on the location and time criteria. The terminal may evaluate each location and time criterion by determining its location within a specified time period and determining whether its location is within or outside a specified target location, as indicated by the presence or absence requirement.

摘要： This application relates to systems and methods for recovering data in multimedia file segments. A communication device may receive a multimedia file segment that includes damaged data. The communication device may replace the damaged data with dummy data to reconstruct the multimedia file segment. The communication device may then play the reconstructed multimedia file segment. Thus, by replacing the damaged data with dummy data, the communication device may play a multimedia file segment even when part of the segment may be damaged.

摘要： Techniques are provided for smooth transition between broadcast/multicast transmission and unicast transmission. A method for managing unicast and multicast services switching in a multi-band/multi-frequency wireless communications system (WCS) capable of both unicast and multicast signaling includes determining whether an aggregate demand for a content provided via dedicated unicast transmissions exceeds a threshold. The method includes switching transmission of the content from the dedicated unicast transmissions on one frequency to a multicast transmission on a second or more frequencies in response to determining that the aggregate demand exceeds the threshold.
摘要翻译：提供了广播/组播传输和单播传输之间的平滑过渡的技术。一种用于管理能够同时进行单播和多播信令的多频/多频无线通信系统（WCS）中的单播和多播服务切换的方法，包括确定对经由专用单播传输提供的内容的总需求是否超过阈值。该方法包括响应于确定总需求超过阈值，将来自一个频率上的专用单播传输的内容的传输切换到第二或更多个频率上的多播传输。
