ABSTRACT:
A television upgrade system allows a consumer to upgrade applications or features in a television (TV) simply by inserting an external device containing an upgrade file into the TV. The TV then executes a boot loader code which automatically replaces an executable code for applications or features currently in the TV with the new or upgraded executable code from the upgrade file. A consumer can also upgrade the boot loader code that maps out where the executable code for the different applications or features are located in memory. This allows the TV to be completely reconfigured for a wider variety of new applications and features. A verification operation can be performed to prevent the TV from being reconfigured with incorrect versions of the boot image and to avoid unauthorized files from being loaded into the TV.
