    Abstract: 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.

    Abstract translation: 提供了一种用于控制视频传送网络中的带宽速率限制和客户端渲染速率限制的方法和系统。 该方法为网络服务提供商提供了覆盖通过动态客户端比特率适配选择的视频传送数据速率以及客户端的视频数据呈现速率的手段，以限制网络拥塞的影响。 还指定了根据该方法实现客户机和代理计算机的系统。 该系统使用标准的基于HTTP的视频传送系统透明地工作，并且包括一个HTTP代理缓存架构，以支持带宽速率限制和客户端渲染速率限制。 该系统进一步提供客户端比特率选择和客户端带宽使用的管理覆盖。

    Abstract: A streaming media system employs dynamic rate adaptation. The method includes a file format compatible with legacy HTTP infrastructure to deliver media over a persistent connection. The method further includes the ability for legacy client media players to dynamically change the encoded delivery rate of the media over a persistent connection. The method provided works transparently with standard HTTP servers, requiring no modification and leverages standard media players embedded in mobile devices for seamless media delivery over wireless networks with high bandwidth fluctuations. A system is also specified for implementing a client and server in accordance with the method.

    Abstract translation: 流媒体系统采用动态速率适配。 该方法包括与传统HTTP基础设施兼容的文件格式，以通过持久连接传递媒体。 该方法还包括传统客户端媒体播放器通过持久连接来动态地改变媒体的编码传送速率的能力。 所提供的方法与标准HTTP服务器透明地工作，不需要修改，并利用嵌入在移动设备中的标准媒体播放器，通过具有高带宽波动的无线网络进行无缝媒体传输。 还指定了根据该方法实现客户端和服务器的系统。

    Abstract: 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.
