Title: BROADCASTING OF SOFTWARE PACKAGES
Abstract:
A broadcast receiver includes a communication interface 210 for receiving data from a broadcast communication system. A storage 260 stores software components executable by processor 250 and stores configuration information identifying the executable software components. The receiver receives through the communication interface a software package description indicating software components that must have been installed in the broadcast receiver before accepting a software package associated with the software package description; and the associated software package including at least one executable software component. The receiver determines whether the software package can be installed by comparing the software package description with the configuration information stored in the storage of the receiver; and upon a positive determination: stores the at least one software component of the software package in the storage and updates the receiver's configuration information accordingly.
