20100319025 | METHOD OF PROCESSING DATA ON EPG IN RECEIVER CONNECTED TO NETWORK AND THE RECEIVER - A digital broadcast receiver is disclosed. The receiver includes a network interface configured to receive provisioning information from a service provider during SP (Service Provider) attachment, wherein the provisioning information has both first metadata on EPG provider information giving locations where EPG data from an EPG data provider can be accessed and second metadata on EPG data locator giving a location where EPG data can be accessed in a pull mode or a push mode, the first metadata having both a target service ID element giving the identifier of a service, which is covered by each of the EPG data provider's EPG data sources, and a type of target services element giving a type of service, which is covered by each of the EPG data provider's EPG data sources, and a controller configured to perform a services discovery procedure using service discovery metadata including at least two components supplied by the service provider. | 12-16-2010 |
20110072465 | METHOD OF PROCESSING EPG METADATA IN NETWORK DEVICE AND THE NETWORK DEVICE FOR CONTROLLING THE SAME - 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. | 03-24-2011 |
20110138421 | METHOD OF PROCESSING EPG METADATA IN NETWORK DEVICE AND THE NETWORK DEVICE FOR CONTROLLING THE SAME - 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. | 06-09-2011 |
