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 (35) for input sources such as audio or video source, a data compression device (34) supplied with an A/D-converted or digitally-converted input source, a data adding device (37) supplied with a data-compressed or compressed input source and an information creation device (36) 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.
