Method of processing epg metadata in network device and the network device for controlling the same

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. Preferably, the performing step includes the steps of receiving a master SI table which locates in a master SI table location in provisioning information, wherein the provisioning information includes multiple elements, an EPG provider information element in the multiple elements having both a first target virtual channel map identifier element and an EPG data locator element, the first target virtual channel map identifier element indicating that services are covered by each of the 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.
