A scalable server includes a plurality of stream pumping engines each accessing a particular storage device of a storage subsystem, and a server processor which receives retrieval requests from subscribers and directs the stream pumping engines to retrieve the requested data streams. Each of the stream pumping engines may include a storage controller coupled to its corresponding storage device for directing retrieval of the requested stream therefrom, a network controller for supplying the retrieved stream to a client network, and a processor for directing the operation of the storage and network controllers. Each of the stream pumping engines may also include a shared memory accessible by the corresponding stream pumping engine processor and the server processor. The shared memory facilitates communication with other stream pumping engines via the server processor and server system bus.

摘要： A method and apparatus for storage and retrieval of multiple data streams in a multimedia distribution system. A given data stream is separated into a plurality of portions, and the portions are stored in a multi-disk storage system with Y disks each having X zones such that the ith portion of the given stream is stored in zone (i mod X) of disk (i mod Y). The number X of zones per disk and the number Y of disks are selected as relatively prime numbers. The stored data are retrieved using Y independent retrieval schedulers which are circulated among the Y disks over a number of scheduling intervals. Each retrieval scheduler processes multiple requests separated into X groups, with the requests of each group accessing the same disk zone during a given scheduling interval. The retrieval schedulers are also configured such that the retrieval requests of a given retrieval scheduler access the same disk during a given scheduling interval. The data stream placement technique in conjunction with the retrieval schedulers provide sequential-like parallel retrieval suitable for supporting real-time multimedia data distribution for large numbers of clients.

摘要： A code tracking system and method especially for use in direct sequence code division multiple access (DS-CDMA) communication systems employs multiple timing references within a chip by tracking the multiple timing references relative to the exact midpoint of the chip, then adjusting the timing references to the exact midpoint of the chip, and outputting an error tracking signal in accordance with the minimum error associated with the multiple timing references. The system performs effective code tracking with low lock-loss rate even when the noise of a receiving path interferes with detection of some of the timing references. The system uses multiple delay-locked loops for the different timing references.
