INTERACTIVE BROADBAND SERVER SYSTEM.

摘要

An interactive broadband server system 109 including multiple processors 205, a backbone switch 203, multiple storage devices 207 and multiple user processes 503. The backbone switch enables high speed communication between the processors. The storage devices are distributed across the processors to store titles, where each title is divided into data chunks 513 that are distributed across the storage devices. The user processes are configured for execution on the processors for interfacing multiple subscriber locations 105. Each user process is operative to retrieve a requested title from two or more of the processors via the backbone switch and to assemble a requested title for delivery to a requesting subscriber location. The storage devices may be organized into RAID groups 401. Distributed media readers 219 and a library storage system 201 may be included. Multiple isochronous titles may be simultaneously delivered to downstream subscribers. Titles may be preprocessed and stored in a predetermined format to reduce loading and processing overhead.
