System for running applications in a resource-constrained set-top box environment

A set-top box system having a limited amount of resources, comprising:

• a hardware layer representing hardware functionality provided by the set-top box system;
• and
• an interpreter-based processing module configured for use in a set-top box environment,
• wherein the hardware functionality includes a line control register (LCR) which provides memory locations which correspond to respective lines on a display device, and
• wherein the set-top box system further comprises graphics functionality configured to provide a graphics effect by manipulating the LCR.

A method for executing an application in a resource-constrained set-top box environment, comprising:

• loading and initializing a current application;
• executing the current application using an interpreter-based processing module configured for use in a set-top box environment;
• pausing the current application when another application is activated that interferes with the current application's user graphics presentation;
• resuming the current application when the other application is deactivated;
• and
• exiting the current application upon the occurrence of an exit event.
