    摘要： The present invention provides loosely-coupled cluster systems comprising a plurality of servers based on storage attached to the plurality of servers. Videos, or other assets, are automatically replicated within the server system to increase the number of concurrent play requests serviceable. The server systems can detect spikes in demand that may exceed the guaranteed number of concurrent play requests serviceable and dynamically transfer the high-in-demand or ‘hot’ asset to servers in the cluster that do not have the video. Alternatively, instead of transferring the entire asset, varying length prefixes of the asset may be transferred depending on the availability of resources. The remainder of the asset is transferred in some embodiments on demand with sufficient buffering or other storage to guarantee playback to the user or subscriber according to the required quality of service (QOS).

    摘要翻译： 本发明提供了松散耦合的集群系统，其包括基于连接到多个服务器的存储器的多个服务器。 视频或其他资产在服务器系统内自动复制，以增加并发播放请求的数量。 服务器系统可以检测到可能超过可保护的并发播放请求数量的尖峰，并将高需求或“热”资产动态地传输到没有视频的集群中的服务器。 或者，代替传输整个资产，可以根据资源的可用性来转移资产的不同长度的前缀。 在一些实施例中，资源的剩余部分在需要时通过足够的缓冲或其他存储来传送，以保证根据所需的服务质量（QOS）向用户或用户播放。

    摘要： System, method, and computer program products for implementing techniques for efficient delivery of variable bit rate streaming media assets having a variety of data formats. An embodiment provides delivery system for use in client server computer architecture in which server provides streaming media assets to at least one client over computer network, wherein media assets can have plurality of data formats, including a packet producer that acquires a streaming media asset in packetized form and places time stamps on packets that specify delivery time for each packet, a time stamp packet queue containing the packets with time stamps in a first in, first out order; and a feeder module that removes packets from the time stamp packet queue and transmits the removed packets to a client via the computer network, transmission for each packet concluded at least by the specified delivery time in each packet.

    摘要： A method, system, and computer readable medium for delivering media object to a user over a computer network. Media object is divided into first portions and remaining portions, and the first portions are stored on edge server computers in communication with client computers. Upon receiving a request for delivery from a user, the edge server computer transmits the first portion of the media object to the client computer. The edge server computer then requests delivery of the remaining portion of the media object from the origin server computer. Upon receipt of the remaining portion of the media object from the origin server computer, the edge server computer transmits the remaining portion of the media object to the user such that delivery of both portions of the media object to the client computer is continuous and uninterrupted.

    摘要： A media server system and process are disclosed that have device independent near-online storage support. A plurality of media assets are stored in online storage, and a plurality of media assets are stored on tertiary storage devices in tertiary storage to provide near-online storage. A media server, having access to the online storage and the tertiary storage, receives a user request for a media asset. The media server then determines whether the requested media asset needs to be loaded from the tertiary storage. If so, the media server allocates space in the online storage for the requested media asset. A transfer process specific to the tertiary storage devices is then used to transfer content of the requested media asset to the online storage.
