A method and system for an embedded software update system, which helps manufactures or vendors avoid costly product recall activities in the event their digital products have field software errors ("bugs") or hardware problems. One aspect of the invention is directed to an error correction system, which remotely corrects these software errors and minimizes influences of hardware problems. Another aspect of the invention is to a software updating system, which is capable of updating software modules in the digital products by use of software patches. The software patch system of the present invention facilitates manufactures' transmitting software patches to the "on-the-fly" digital products to fix software errors and minimize influences of hardware problems. The software patch may also contain new parameters for updating some data area in NVM (Non Volatile Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory) memory of a digital product, which is quite useful when service providers or manufactures want to modify some service features or product features.
