System for creating contents information and for avoiding download errors of the contents information

Abstract

A method of and apparatus for creating contents in which contents information of source may be created within an authoring processing thereby to avoid a mistake from occurring when contents information is downloaded onto a server. An apparatus for creating contents information includes an A/D converting device () for input sources such as audio or video source, a data compression device () supplied with an A/D-converted or digitally-converted input source, a data adding device () supplied with a data-compressed or compressed input source and an information creation device () of contents information for input source. Since a table of contents information concerning input sources may be simultaneously saved for the authoring processing in which an input source is compressed, it is possible to remove a contents information creation work required when contents information may be downloaded onto an AV server which is restricted from a time and place standpoint.
