摘要： Live media streams are delineated for distributed encoding and fragmentation in a dynamically scalable distributed resource system. In some examples, live MPEG-2 media streams are separated into groups of pictures (GOPs) and converted into jobs for encoding and fragmentation systems. Multiple jobs may be created for the same live media stream to provide for different quality levels for each fragment of each channel. Shared resources such as a pool of dynamically scalable virtual machines can be used to process the individual jobs. Encoded fragments may be H.264 fragments maintained on shared storage. A particular live stream corresponding to a particular quality level can be reconstructed using the encoded fragments.

摘要： A media stream is delineated into multiple fragments. Different watermark variants of individual fragments are generated. Particular sequences of watermark variants are selected for particular clients and maintained in a user access database. Analyzing media streams allows determination of the sequences of watermark variants and identification of particular clients intended to receive the media streams. Fragments can continue to be cached efficiently and unique watermarks need not be generated for each individual client.

摘要： A media stream delivery system encodes and fragments media streams into numerous media stream fragments maintained on fragment servers. Playlist information, media data, and bandwidth adaption data is provided as box information with media stream fragments to reduce the number of client requests required to begin playback or perform a channel change. A client no longer needs to make separate requests for bandwidth adaptation data, media data, or playlist information. Playback can begin as soon as sufficient media stream fragments are received.
摘要翻译：媒体流传送系统将媒体流编码并分割成片段服务器上维护的许多媒体流片段。播放列表信息，媒体数据和带宽适配数据作为具有媒体流片段的盒信息提供，以减少开始播放或执行频道改变所需的客户端请求的数量。客户端不再需要对带宽适配数据，媒体数据或播放列表信息进行单独请求。收到足够的媒体流片段后，即可开始播放。

摘要： A live media stream encoding system encodes live media streams into numerous variants of the live media streams each including multiple fragments. Live media streams are delineated, dispatched as jobs, and converted using distributed and dynamically scalable encoder and fragmenter resources without using any centralized encoding management system. Encoded fragments are maintained in shared storage and accessed as needed by devices during playback. Localized redundancy and/or geographic redundancy is provided throughout the system to prevent disruption upon failure of a particular node.

摘要： Live media streams are encoded and fragmented to generate encoded fragments appropriate for different devices and networks. Different encoded fragments may correspond to different resolutions, audio bit rates, quality levels, and even codecs, etc. Devices request encoded fragments as needed to reconstitute a live media stream for playback. In many instances, encoding and fragmentation jobs are provided to numerous distributed and scalable encoder and fragmenter systems. Encoding and fragmentation jobs are intelligently weighted and scheduled to prevent any disruption or delay in playback of any particular live stream.

摘要： Mechanisms are provided for performing real-time synchronization of key frames across multiple streams. A streaming server samples frames from variant media streams corresponding to different quality levels of encoding for a piece of media content. The streaming server identifiers key frames in the media streams and points in time to sample for key frames that increase the chances of detecting key frames from the same group of pictures (GOPs). In some examples, the sampling point is substantially in the middle between two GOPs. When a connection request is received from a client device for an alternative stream, a measured delay is used to calculate an improved start time.
摘要翻译：提供了用于在多个流之间执行关键帧的实时同步的机制。流服务器从对于一片媒体内容的不同质量等级编码的不同媒体流中采样帧。流媒体服务器识别媒体流中的关键帧和时间点对于增加从同一组图像（GOP）检测关键帧的机会的关键帧进行采样的时间点。在一些示例中，采样点基本上在两个GOP之间的中间。当从替代流的客户端设备接收到连接请求时，使用测量的延迟来计算改进的开始时间。

摘要： Described herein are techniques for facilitating combined broadcast and unicast delivery of content. According to various embodiments, a media stream from a content provider may be received at a unicast server and at a broadcast server. The media stream may comprise a plurality of media stream fragments. A relative delay may be introduced into the media stream at the broadcast server such that media stream fragments transmitted from the broadcast server are delayed relative to media stream fragments transmitted from the unicast server. The media stream fragments may be transmitted to a user device. The user device may be operable to switch between receiving the media stream fragments from the unicast server and the broadcast server.
