Abstract
A computer-implemented method and apparatus for restoring operating systems within a set-top box system. The restoration provides for operating a first operating system in a first memory. An application program is operated in a second memory. The first operating system is stored in a second memory so that a second operating system is loaded into the first memory. When a predetermined condition which is associated with the second operating system is detected, the first operating system is loaded into the first memory in response to the detected predetermined condition. Such a system provides such non-limiting advantages to the set-top box as the ability to robustly recover from errors or anomalies associated with downloading an operating system.
