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： Analytics information is collected in a content delivery network when content requests are received by a content router. Analytics information may be gleaned from uniform resource identifiers, and additional augmented analytics information may be specified by either the client that issued the request or an intermediate network node that proxied the request. The augmented analytics information may be specified in proprietary HTTP header fields. Information collection includes intercepting content requests; correlating URIs with known content assets; associating content requests with session state; extracting downstream node augmented information from the content requests; updating session information in persistent storage; selecting target locations from which to retrieve the content assets; and redirecting the content requests to the target locations.
摘要翻译：当内容路由器接收到内容请求时，分析信息被收集在内容传送网络中。可以从统一资源标识符收集分析信息，并且可以由发出请求的客户端或代理请求的中间网络节点指定附加的增强分析信息。增强的分析信息可以在专有HTTP头域中指定。信息收集包括拦截内容请求; 将URI与已知内容资产相关联; 将内容请求与会话状态相关联; 从内容请求中提取下游节点增强信息; 在持久存储中更新会话信息; 选择要从中检索内容资产的目标位置; 并将内容请求重定向到目标位置。

摘要： A method and apparatus provide streaming delivery of data such as media data (video, audio) using a non-streaming delivery mechanism such as HTTP along with server-side pacing of the delivery. An initial portion of the media data is preloaded to a client buffer in a bursting manner to minimize latency. The method may include client request verification, support for client self-pacing, and support for catch-up pacing reductions. A proxy server apparatus may also be used which employs both server-side and client-side pacing and may include caching and both cache and client preloading for minimized latency. A similar proxy server apparatus may be used to provide an efficient alternative to client polling for data from a polled data service, such as stock quotes etc., using streaming updates. The method may include support for stream modification through persistent client requests.

摘要： A method is provided for managing key rotation (use of series of keys) and secure key distribution in over-the-top content delivery. The method provided supports supplying a first content encryption key to a content packaging engine for encryption of a first portion of a video stream. Once the first content encryption key has expired, a second content encryption key is provided to the content packaging engine for encryption of a second portion of a video stream. The method further provides for notification of client devices of imminent key changes, as well as support for secure retrieval of new keys by client devices. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.

摘要： In a system for streaming data over a network, the type and rate of streaming are automatically varied based on available network bandwidth. Video media is transcoded into different bit rate encodings that are divided into segment files. Segments are sent from a network-aware adaptive streaming (NAAS) server and reassembled and presented to a media player at a client device. The system may download additional segment files ahead of time from multiple NAAS servers to increase throughput. A playback status (“bookmark”) may be maintained to keep track of what the user has viewed and to allow the user to continue playing from where the user left off. The user may continue watching from the bookmark point on the same device or on a different device.
摘要翻译：在用于通过网络流式传输数据的系统中，流的类型和速率根据可用的网络带宽而自动变化。视频媒体被转码成不同的比特率编码，分为段文件。分段从网络感知自适应流（NAAS）服务器发送，并重新组合并呈现给客户端设备上的媒体播放器。系统可以提前从多个NAAS服务器下载附加段文件，以提高吞吐量。可以维持播放状态（“书签”）以跟踪用户已经观看的内容，并允许用户从用户离开的地方继续播放。用户可以继续从同一设备上或不同设备上的书签点观看。
