Video Content Management Using Logical Content

摘要

A common video file format is generally used in video content management system composed of modules for archiving, retrieving, and video streaming on a network. However, the file format may not be suitable for these functions. This paper presents a new video content management that uses logical content. Logical content makes it possible to manage a system that may use files of differing formats to store the same content to be used by different modules. Using logical content makes it possible to access physical video files regardless of their formats, and to easily manage video content consisting of multiple physical files. Other modules are able to request the retrieval of a physical file by specifying a logical content ID and its range. Consequently, this system can be designed to be both modularized and extended. We also present an experimental video content management system that verifies the effectiveness of our video content management system.
