ABSTRACT:
A system and method for downloading software updates for receivers of broadcast content data distribution has multiple memories for storing the updated version of code as well as a backup copy of the prior version of code. Code is replaced with an updated version when the updated version passes a series of checks. Thereafter the updated version is designated the current version. Thereafter the backup version is changed. The method updates operational code without interrupting the execution of regular receiver functionality, such as the playing of audio and/or video. The system provides for updating operational code in option cards.
