    • 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.
    • 根据本发明的一个实施例的在网络中处理EPG元数据的方法包括以下步骤:利用由服务提供商提供的多个服务发现元数据组件和处理EPG元数据来执行服务发现过程。 优选地,执行步骤包括以下步骤:接收位于供应信息中的主SI表位置的主SI表,其中所述供应信息包括多个元件,所述多个元件中的EPG提供商信息元素具有第一目标虚拟通道 映射标识符元素和EPG数据定位符元素,第一目标虚拟频道映射标识符元素,指示服务被每个EPG元数据提供者的EPG数据源覆盖,接收位于所接收的虚拟频道映射位置的虚拟频道映射表 主SI表,接收位于接收到的虚拟频道映射表中的虚拟频道描述表位置的虚拟频道描述表,以及接收位于所接收的虚拟频道描述表中的源表位置的源表。
