A receiver ( 50 ) having software contained within a non-volatile memory ( 52 ) that can be upgraded via a communication interface ( 62 ). The receiver ( 50 ) provides a standby mode that works in conjunction with an operational mode to search ( 16 ) for and load ( 28 ) software updates. If an available update is found, the receiver records an indication ( 44 ) that a software update is available to allow for loading ( 28 ) and installing ( 22 ) of the update. The receiver can locate updates in the standby mode generate an indication for the receiver that upon entering the operational mode, the indication that a software update is available is identified and the system software then loads the new software update. The receiver is capable of searching for software updates during the operational mode and if available update is found, the receiver loads it the update into memory and upon re-entering of the standby mode, the update stored in memory is placed into a predetermined non-volatile memory so that the update is available the next time the operating mode is entered.
