Abstract
Methods and apparatus for efficient network information acquisition over a DVB network. In an aspect, a method includes identifying an IP/MAC platform, acquiring network information table (NIT) information in a transport stream being transmitted on a forward link frequency, acquiring IP/MAC network table (INT) information associated with the IP/MAC platform based on the NIT information, creating a network list that identifies all networks referred to by all stream location descriptors associated with the selected IP/MAC platform based on the INT information, and acquiring network information for all the networks in the network list. In an aspect, an apparatus includes means for identifying an IP/MAC platform, means for acquiring NIT information, and means for acquiring INT information, means for creating a network list that identifies networks associated with the selected IP/MAC platform, and means for acquiring network information for all the networks in the network list.
