Abstract: A method of processing EPG metadata in a network according to one embodiment of the present invention includes the steps of performing a services discovery procedure utilizing multiple service discovery metadata components supplied by a service provider and processing an EPG metadata. Moreover, the performing step includes the steps of receiving a master SI table which locates in a master SI table location in provisioning information, the provisioning information including multiple elements, an EPG provider information element in the multiple elements having both a first delivery layer element and an EPG data locator element, the first delivery layer element giving a type of delivery layer that is delivered by at least one of an EPG metadata provider's EPG data sources, receiving a virtual channel map table which locates in virtual channel map locations in the received master SI table, receiving a virtual channel description table which locates in virtual channel description table locations in the received virtual channel map table, and receiving a source table which locates in source table locations in the received virtual channel description table.
