摘要： A peer-to-peer (P2P) video-on-demand (VoD) system or method use a plurality of LP-enabled VoD set-top box (STB) peers in a pool for providing video content data to a requesting client peer in the pool. One other peer in the pool can be designated as a parent peer for downloading high priority playback content that is substantially immediately needed for playback display. Low priority pre-fetch content can be downloaded to the requesting client peer from another peer in the pool other than the parent peer. Bandwidth at the requesting client peer that is not used by the playback module for downloading the high priority playback video content data can be allocated for downloading the pre-fetch content. Using the requesting client peer, video content data can be served, for the playback display on a video monitor, wherein such served video data content can comprise the playback content and the prefetch content.

摘要： This patent document describes, among other things, distributed computer platforms for online delivery of multimedia, including HD video, at broadcast audience scale to a variety of runtime environments and client devices in both fixed line and mobile environments. The teachings hereof can be applied to deliver live and on-demand content streams via computer networks. The teachings also relate to the ingestion of content streams in a given source format and the serving of the stream in a given target format. For example, a system might have machines in a content delivery network that ingest live streams in a source format, use an intermediate format to transport the stream within the system, and output the stream in a target format to clients that have requested (e.g., with an HTTP request) the stream. The streams may be archived for later playback.
摘要翻译：该专利文献尤其描述了用于在广播受众范围内在固定线路和移动环境中的各种运行时环境和客户端设备的在线传送多媒体（包括高清视频）的分布式计算机平台。其教导可应用于通过计算机网络提供实况和点播内容流。该教导还涉及以给定的源格式摄取内容流和以给定目标格式提供的流。例如，系统可以在内容传送网络中具有以源格式摄取直播流的机器，使用中间格式来传输系统内的流，并将目标格式的流输出到已请求的客户端（例如，具有HTTP请求）流。流可以归档以供稍后播放。
