Abstract:
A system and method for updating a remote display unit that communicates with a computing system are described. The method includes accessing display update information from an update queue that stores drawing commands issued by an application executing on the computing system, caching the display update information, applying a lossy compression algorithm to the display update information to create a lossy display update, and transmitting the lossy update to the remote display. The method also includes applying a lossless compression algorithm to the display update information in the cache to create a lossless display update and transmitting the lossless display update a predetermined of time after transmitting the lossy update.
