Abstract
A system and method for accurately rendering an interactive TV application is accomplished by adjusting the contents of an on-screen buffer (OSD) to match the native physical characteristics of a target display device, preferably using fonts specific to the display device. Typically the character data is merged with graphics data and still or moving video background information and passed to the display using an analog or digital interface. Since the native resolution of the display is ideally identical to the resolution of the OSD buffer, the display device will not need to enlarge or reduce the rendering of the application. As a result, the character and graphics data will not be distorted by the display rasterizing process.
