摘要： A live streaming system/method provides cross platform live streaming capabilities to mobile devices. A file format compatible with legacy HTTP infrastructure is used to deliver media over a persistent connection. Legacy client media players can dynamically change the encoded rate of the media delivered over a persistent connection. Standard HTTP servers may be used without modification, leveraging standard media players embedded in mobile devices for seamless media delivery over wireless networks with high bandwidth fluctuations.

摘要： A system for media delivery includes a server-side proxy for aggregating and encrypting stream data for efficient HTTP-based distribution over an unsecured network. A client-side proxy decrypts and distributes the encapsulated stream data to client devices. A multicast-based infrastructure may be used for increased scalability. The encoded rate of the media delivered over the persistent HTTP proxy connections may be dynamically adapted. The client-side proxy may be integrated within a mobile device for maximum network security and reliability.

摘要： A method and system is provided for controlling bandwidth rate limiting and client rendering rate limiting in a video delivery network. The method provides network service providers with a means for overriding video delivery data rates selected through dynamic client bitrate adaptation, as well as video data rendering rates of the clients, to limit the impact of network congestion. A system is also specified for implementing a client and a proxy computer in accordance with the method. The system works transparently with standard HTTP-based video delivery systems and includes an HTTP proxy cache infrastructure to support bandwidth rate limiting and client rending rate limiting. The system further provides for administrative overrides of client bitrate selection and client bandwidth usage.

摘要： Media content is delivered to a variety of mobile devices in a protected manner based on client-server architecture with a symmetric (private-key) encryption scheme. A media preparation server (MPS) encrypts media content and publishes and stores it on a content delivery server (CDS), such as a server in a content distribution network (CDN). Client devices can freely obtain the media content from the CDS and can also freely distribute the media content further. They cannot, however, play the content without first obtaining a decryption key and license. Access to decryption keys is via a centralized rights manager, providing a desired level of DRM control.
摘要翻译：基于具有对称（私钥）加密方案的客户机 - 服务器架构，媒体内容以受保护的方式传送到各种移动设备。媒体准备服务器（MPS）加密媒体内容并将其发布并存储在诸如内容分发网络（CDN）中的服务器的内容递送服务器（CDS）上。客户端设备可以从CDS自由获取媒体内容，还可以进一步自由地分发媒体内容。然而，他们不能在没有首先获得解密密钥和许可证的情况下播放内容。访问解密密钥是通过集中权限管理器提供所需级别的DRM控制。

摘要： A media navigation system provides a user interface for navigating and interacting with streamed media objects, including video. The system may employ media markers representing time locations within a media file in addition to images or other representations derived from the media object. The system displays a tile layout representing a sequence of the media at an interval comprising a set of sub intervals corresponding to the tiles, and enables a user to click on the tiles to navigate to a next set of tiles which correspond to a different interval, and which replace the currently displayed tiles on the display. Navigation can include zooming in (smaller interval), zooming out (larger interval) and 'panning' (preceding or succeeding interval) at arbitrary intervals. Individual tiles may also include visual indicators of relative importance or activity such as the number of comments associated with a sub interval.
摘要翻译：媒体导航系统提供用于导航和与流媒体对象（包括视频）交互的用户界面。除了从媒体对象导出的图像或其他表示之外，系统还可以使用表示媒体文件内的时间位置的媒体标记。系统以包括与瓦片对应的一组子间隔的间隔显示表示介质序列的瓦片布局，并且使得用户能够点击瓦片以导航到对应于不同间隔的下一组瓦片，并且替换显示器上当前显示的瓦片。导航可以包括以任意间隔放大（较小间隔），缩小（较大间隔）和“平移”（前一个或后续间隔）。单个瓦片还可以包括相对重要性或活动的视觉指示符，例如与子间隔相关联的评论的数量。

摘要： A client device for media playback includes a user-installable media client application which implements the client-side of a digital rights management (DRM) system. The client device employs secure boot and verifies the user-installed application. The application is hardened against reverse engineering, and it utilizes a special API provided by the client device to tie into the secure boot, bridging the gap between the secure boot and the client-side of the DRM system contained within the application.
