A program execution device is provided which, even when a currently executed application (program) abnormally terminates, can prevent the application from becoming unusable, and thereby improve user convenience. An MA management unit includes: an MA management unit main for receiving an instruction from an initialization subprogram and controlling the other constituent elements in the MA management unit; an XAIT obtainment analysis unit for analyzing an XAIT sent from the head end; an MA selection unit A for selecting a program to be activated, according to the XAIT analysis result; an MA activation unit for activating of the specified program; an MA monitoring unit for monitoring the operational state of the specified program and notifying when an abnormal termination has occurred; and an MA selection unit B for selecting an alternative program.
