摘要

A Set-Top Box configured with a modem and a Main Circuit Board consistent with certain embodiments learns the modem's IP address by establishing a predetermined relationship between a hardware address of the modem and a hardware address of the Main Circuit Board; at the Main Circuit Board: ascertaining the hardware address of the modem from the predetermined relationship; sending a query from the Main Circuit Board to the hardware address of the modem requesting the modem's IP address; and receiving a reply from the modem providing the modem's IP address to the Main Circuit Board. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
