Title:
【発明の名称】コンピュータネットワーク上の多様なビデオデータを選択し復元するためのシステムと方法
Document Type and Number:
Japanese Patent JP2001527668
Kind Code:
A
Abstract:
A system and method for the selection and retrieval of various types of video data from distributed delivery sites calls for the deployment of "Smart Mirror" sites throughout a network, each of which maintains a copy of certain data managed by the system. Each "Smart Mirror" site maintains copies of the data in several alternative file formats. Every user is assigned to a specific delivery site based on an analysis of network performance with respect to each of the available delivery sites. Generalized network performance data is collected and stored to facilitate the selection of additional delivery sites and to ensure the preservation of improved performance in comparison to traditional networks. The appropriate file format is automatically selected based on the capabilities of a user terminal making a request for data.
