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： 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.
摘要翻译：一种方法和装置使用诸如HTTP之类的非流传送机制以及递送的服务器端起搏来提供诸如媒体数据（视频，音频）之类的数据流传送。将媒体数据的初始部分以突发方式预加载到客户机缓冲器以最小化等待时间。该方法可以包括客户端请求验证，对客户端自定进度的支持，以及对追赶起搏降低的支持。还可以使用代理服务器装置，其采用服务器端和客户端起搏，并且可以包括缓存以及缓存和客户端预加载以最小化等待时间。可以使用类似的代理服务器装置来提供使用流更新的来自轮询数据服务（例如股票报价等）的数据的客户端轮询的有效替代。该方法可以包括通过持久客户端请求支持流修改。

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。

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 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.
