Systems for generating and transmitting a video stream that is encoded with program data such that when decoded can be executed to update non-volatile storage within a video based electronic device. Typically video based electronic devices are controlled by processors running software stored in writable, non-volatile storage. It is often desirable or necessary to update the software after the device has been shipped from a factory in order to correct a software failure discovered after shipment or to incorporate a new set of features. As many video based electronic devices have no common interface available to connect a computer, there is no ability to receive a software update. However, most video based electronic devices can be connected to a video source. Therefore, systems that allow a video based electronic device to receive, decode, and execute program data that is encoded within a video stream are presented. A method for encoding program code into a video stream is also presented.
