Providing compressed video

Abstract

A computer may be remotely accessed. At a first location, display commands are generated. The display commands are covered into a compressed video data stream. Each display element ( 5 ) is checked if it is encoded ( 52 ). If object is encoded, it is transcribed into MPEG ( 54 ). The image is adjusted for display ( 56 ) and compression ( 58 ). Additional steps of motion determination ( 60 ), change detection ( 62 ), compression depth and frame determination ( 66, 68 ) are executed. Then the data is transmitted to a second location. The display commands are decompressed and displayed as an image at the second location.

1 . A method of generating a plurality of displays, comprising: 
 generating a first set of display commands, by a first program;    generating at least a second set of display commands, by at least a second program;    differentially affecting said first and said second programs, to generate said display commands; and    converting each of said first and said second sets of display commands into a compressed video stream,    wherein said differentially affecting comprises differentially affecting to meet an instantaneous resource limitation.    
   
   
       2 . A method according to  claim 1 , wherein said resource limitation comprises a transmission bandwidth limitation.  
   
   
       3 . A method according to  claim 1 , wherein said resource limitation comprises a limitation on CPU available to perform said conversion.  
   
   
       4 . A method of generating a plurality of displays, comprising: 
 generating a first set of display commands, by a first program;    generating at least a second set of display commands, by at least a second program;    differentially modifying said first and said sets of display commands; and    converting each of said first and said second sets of display commands into a compressed video stream,    wherein said differentially modifying comprises differentially modifying to meet an instantaneous resource limitation.    
   
   
       5 . A method according to  claim 4 , wherein said resource limitation comprises a transmission bandwidth limitation.  
   
   
       6 . A method according to  claim 4 , wherein said resource limitation comprises a limitation on CPU available to perform said conversion.
