Abstract:
1. A system to display a user interface for a telematics client incorporated in a vehicle, comprising: a display panel configured to display image data of the user interface, wherein the user interface defined to display a data that is being received from an application executing in a telematics server, the data being received from the application executing in the telematics server via a carlet application running in the telematics client and the telematics client incorporated in the vehicle is in communication with the application through a wireless network and the display panel displays the image data of the user interface associated with only one carlet application at a time; a graphics processor in communication with the display panel; a draw manager in communication with the graphics processor to manage updating of the display panel and to relieve the carlet application from managing the updating of the display panel; and an application buffer, located at the telematics client, in communication with the draw manager, the application buffer configured to receive the image data from the carlet application and the carlet application configured to receive the data from the application executing in the telematics server, the application buffer further configured to transmit the image data to the draw manager at a first rate, wherein the draw manager is configured to determine a rate of updating an object of the display image through an interpolation between values associated with most recent image data received from the application buffer and values associated with previous image data in the draw manager.
