Abstract: A disk scheduling system with bounded request reordering. Disk access requests may be performed during traversals of a disk head across a disk. Each traversal may have a specified direction of motion. A plurality of disk accesses may be performed during a disk head traversal. The overall number of disk access requests for a given disk head traversal may be limited to a maximum number N. By limiting the number of disk requests for each traversal, a bound may effectively be placed on the amount of time it takes to satisfy any single disk request.

Abstract: A plurality of movies are distributively stored in digital form on a mass storage unit such as a Redundant Array of Inexpensive Drives (RAID) disk drive system (32). A master controller (36) receives movie requests from users, and generates designation commands through a Small Computer System Interface (SCSI) bus (38) that designates a retrieval controller (40) at the requesting user's facility, and locations of the requested movie data in the RAID system (32). Successive designation commands are generated for successive blocks of the movie data. A designated retrieval controller (40) reads a designated block of data from the RAID system (32) through the SCSI bus (38), and converts the retrieved data into video picture and audio format at the requesting user's facility. The movie data is preferably compressed on the RAID system (32) in Motion Picture Experts Group (MPEG) format, and decompressed by the retrieval controllers (40).

Abstract: Provided is a method and system for splitting a video stream into X minute video segments and further dividing those video segments into M multiplex files. Each multiplex file can have a Time to Live (TTL). This allows for part of the video to be deleted from disk by just removing a single multiplex file. The remaining multiplex files can be combined to play back the video at a reduced sample rate.

Abstract: A system (20), method (60) and apparatus (28) for distributing Video-On-Demand (VOD) content to one or more client devices (28). The system (20) has a more distributed network architecture compared to conventional VOD system architectures, which allows VOD content to be delivered to the client devices (28) more efficiently. The system (20) includes a resource management controller (24) coupled to one or more content servers (22) and coupled to a plurality of client devices (28) via a distributed network link (32). The resource management controller (24) controls the delivery of VOD content to a requesting client device (28) from the one or more servers (22) and/or one or more client devices (28) configured as host client devices. Client devices (28) configured as host client devices can not only request video content from servers and other client devices, but also can transmit video content stored therein to other client devices.

Abstract: A system and method is described for stream caching content that is being provided to one or more users over a network. The streaming content may be split into a plurality of file sections (F1, F30), which may then be further split into a number of subfiles (S1, S4). These subfiles may then be streamed to a plurality of users over a network. In one embodiment, file sections may be cached on a common caching server and accessed by subsequent users without having to wait until the entire requested file has been streamed to a preceding user.

Abstract translation: 描述了用于通过网络提供给一个或多个用户的流缓存内容的系统和方法。 流式传输内容可以被分割成多个文件部分（F1，F30），然后可以进一步将其分割成多个子文件（S1，S4）。 然后可以通过网络将这些子文件流传输到多个用户。 在一个实施例中，文件部分可以被缓存在公共高速缓存服务器上并由后续用户访问，而不必等到整个所请求的文件已经被流传输到前一个用户。
