摘要： A content delivery system stores large content as frames of video that can be served by content servers already optimized for streaming video. Instead of storing image tiles in separate files, the system treats each tile as a frame of a video and stores the tiles in a video format. This allows transfer of large data from a publisher to a content server by transferring a single file or a small handful of files (rather than thousands or millions of files). Web servers such as MICROSOFT Internet Information Server (IIS) include smooth streaming support that can return individual images as video frames as though the images were stored in separate files. Thus, the content delivery system provides easier management of large data for publishers while continuing to provide a smooth experience consuming the data for clients.

摘要： A smooth streaming system provides a stateless protocol between a client and server in which the server embeds incremental control information in media fragments. The server provides uniform media fragment responses to media fragment requests that are cacheable by existing Internet cache infrastructure. The smooth streaming system receives media data in fragments from one or more encoders, creates an index of each fragment, and stores the fragments. The server provides fragments to clients that contain metadata information describing the encodings available on the server and the encoding of the fragment. The server may also provide information within each fragment that allows the client to determine whether the client is requesting data too fast or too slow, so that the client can adapt its request rate to a cadence in tune with the rate at which the server is receiving encoder data.

摘要： A reliable streaming system increases reliability of live and on-demand streaming media events through a robust server architecture that allows fast failover and recovery in the event of network, hardware, or other failures. The system provides for failover of encoders, ingest servers, which receive encoded media data from encoders, and origin servers, which serve as the retrieval point of last resort for connecting clients. The system also provides a push proxy mechanism that allows one copy of data to feed redundant servers and pre-warm caches, saving on provisioned bandwidth. In addition, the system provides a distribution server role that allows content to be automatically syndicated to a region when needed. Thus, the reliable streaming system provides a streaming solution with no single point of failure and redundancy and fast failover built into the content network architecture.
摘要翻译：可靠的流媒体系统通过强大的服务器架构提高实时和点播流媒体事件的可靠性，可在网络，硬件或其他故障情况下实现快速故障转移和恢复。该系统提供编码器，摄像服务器，从编码器接收编码的媒体数据和原始服务器的故障转移，作为连接客户端的最后手段的检索点。该系统还提供了一种推送代理机制，允许一个数据副本提供冗余服务器和预热缓存，从而节省提供的带宽。此外，系统还提供了分发服务器角色，允许内容在需要时自动聚合到某个区域。因此，可靠的流系统提供了一种流式解决方案，没有单点故障和冗余，并且快速故障切换内置于内容网络架构中。

摘要： Media fragmentation may be provided. First, a request for a manifest may be received from a client. Then, in response to the received request for the manifest, the manifest may be sent to the client. Next, a request may be received from the client for a file fragment. The request may indicate a start time and an end time corresponding to the file fragment. The request may be in a format defined by the manifest. Then a lookup table may be queried for a first byte location in a media file corresponding to the start time and a second byte location in the media file corresponding to the end time. Next, a portion of the media file between the first byte location and the second byte location may be extracted from the media file. The portion may comprise the file fragment. The file fragment may be sent to the client.

摘要： An adaptive streaming system is described herein that provides a stateless connection between the client and server for streaming media playback in which the data is formatted in a manner that allows the client to make decisions and react more quickly to changing network conditions. The client requests uniform chunks of media from the server that include a portion of the media. The adaptive streaming system requests portions of a media file or of a live streaming event in small-sized chunks each having a distinguished URL. This allows streaming media data to be cached by existing Internet cache infrastructure. Each chunk contains metadata information that describes the encoding of the chunk and media content for playback by the client. The server may provide chunks in multiple encodings so that the client can switch quickly to chunks of a different bit rate or playback speed.
摘要翻译：本文描述了一种自适应流系统，其在客户端和服务器之间提供用于流媒体回放的无状态连接，其中以允许客户端做出决定并且更快地响应于变化的网络条件作出反应的方式对数据进行格式化。客户端从包含媒体的一部分的服务器请求均匀的媒体块。自适应流系统以各自具有区别URL的小尺寸块中的媒体文件或实时流传输事件的部分进行请求。这允许流媒体数据由现有的因特网缓存基础设施缓存。每个块包含描述用于由客户端回放的块和媒体内容的编码的元数据信息。服务器可以以多个编码提供块，以便客户端可以快速切换到不同比特率或播放速度的块。

摘要： A streaming abstraction system is described herein that provides application developers a client software development kit (SDK) on top of which to build smooth streaming solutions. The system reduces development time considerably and abstracts platform specific intricacies and protocol handling on the client. In addition, the streaming abstraction system makes it possible to monetize streaming content with advanced features like advertising and analytics and provides advanced capabilities like multiple camera angles, diagnostics, and error handling. In some embodiments, the streaming abstraction system provides an intermediate layer that operates between an application and an underlying client media platform. The intermediate layer manages smooth streaming protocol handling as well as interactions with the platform-specific runtime.

摘要： A live caching system is described herein that reduces the burden on origin servers for serving live content. In response to receiving a first request that results in a cache miss, the system forwards the first request to the next tier while “holding” other requests for the same content. If the system receives a second request while the first request is pending, the system will recognize that a similar request is outstanding and hold the second request by not forwarding the request to the origin server. After the response to the first request arrives from the next tier, the system shares the response with other held requests. Thus, the live caching system allows a content provider to prepare for very large events by adding more cache hardware and building out a cache server network rather than by increasing the capacity of the origin server.
摘要翻译：这里描述了实时缓存系统，其减少了用于服务实况内容的原始服务器的负担。响应于接收到导致高速缓存未命中的第一请求，系统将第一请求转发到下一层，同时“保持”其他对相同内容的请求。如果系统在第一个请求未决时接收到第二个请求，则系统将识别出类似的请求未完成，并且通过不将请求转发给原始服务器来保持第二个请求。在第一个请求的响应从下一个层次到达之后，系统与其他持有的请求共享响应。因此，实时缓存系统允许内容提供商通过添加更多的高速缓存硬件和构建缓存服务器网络来准备非常大的事件，而不是增加源服务器的容量。

摘要： A low latency streaming system provides a stateless protocol between a client and server with reduced latency. The server embeds incremental information in media fragments that eliminates the usage of a typical control channel. In addition, the server provides uniform media fragment responses to media fragment requests, thereby allowing existing Internet cache infrastructure to cache streaming media data. Each fragment has a distinguished Uniform Resource Locator (URL) that allows the fragment to be identified and cached by both Internet cache servers and the client's browser cache. The system reduces latency using various techniques, such as sending fragments that contain less than a full group of pictures (GOP), encoding media without dependencies on subsequent frames, and by allowing clients to request subsequent frames with only information about previous frames.
