UNIDIRECTIONAL TPEG SERVICE'S MAP INFORMATION ACQUISITIONS AND CONDITION/METHODS/PROCEDURE FOR CABLE AND WIRELESS BIDIRECTIONAL TELECOMMUNICATIONS

摘要

A method for obtaining geometrical information of unidirectional TPEG service is provided to broadcast various information by providing large picture information through wire and wireless internet networks. A TPEG(Transport Protocol Expert Group) service provider(100) provides a TPEG service to user terminals(120) using DMB(Digital Multimedia Broadcasting) networks. Geometry, image, and motion image information, which are stored in a database of a first TPEG service provider through a domain server for managing geometry/image information, are provided through wire and wireless internet networks when the user terminals request image information of a specific service message while performing the TPEG service.
