Abstract

Disclosed is an index data stream structure for digital contents metadata containing an encoded multi-key for digital contents metadata defined in the TV-Anytime forum (that is, TVA metadata), thereby allowing a receiver receiving the digital contents metadata to locate the metadata meeting a plurality of conditions, that is, composite conditions, in a prompt and efficient manner, by providing an encoded multi-key of the digital contents metadata. The present invention provides a method of accessing an encoded multi-key indexing in order to provide functions for an efficient location and an access relative to the TVA metadata fragment, thereby allowing the receiver receiving the TVA metadata to search for composite conditions for the TVA metadata in an efficient manner.
