Abstract
A system and method for downloading update data to a targeted peripheral device connected to a broadcast receiver such as an integrated receiver decoder (IRD). The update data is received via a broadcast transmission. The system features one or more peripheral devices interconnected to the IRD. The IRD receives a broadcast digital bit stream and processes contents of its header information if it is targeted for the IRD. Next, the IRD determines whether the digital bit stream includes update data to be downloaded and which peripheral device is targeted to receive the update data. Thereafter, the IRD causes the update data to be loaded into the targeted peripheral device.
