METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING ELECTRONIC SERVICE GUIDE IN DIGITAL BROADCASTING SYSTEM

摘要

A method and an apparatus for transceiving an ESG(Electronic Service Guide) in a digital broadcasting system are provided to deliver ESG delivery information through an ESG bootstrap session for both of a broadcasting ESG and a PTP ESG. By parsing a delivery mode of an ESG, it is determined whether the ESG can be delivered through a broadcasting network(402,404). If so, first information indicating that a broadcasting ESG is transported is set(406). If the ESG can be delivered in PTP(Point-To-Point) through an interactive network, second information indicating that PTP ESG is transported is set(410,412). ESG delivery information including at least one of the first and second information is loaded on at least one of an ESG provider discovery descriptor, an ESG access descriptor and a unique ESG transport descriptor of an ESG bootstrap session so as to be transmitted to a terminal through the ESG bootstrap session(416).
