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 transmitting a plurality of similar compressed video channels, comprising: 
 transmitting a base compressed image stream on a first channel;    transmitting modifications to said base image stream on at least one second channel;    receiving, at a display location, said first and said second channel;    modifying said first channel utilizing said second channel; and    displaying said modified first channel at said display location.    
   
   
       2 . A method according to  claim 1 , wherein one channel of said at least one second channel is targeted for said display location.  
   
   
       3 . A method according to  claim 1 , wherein transmitting comprises transmitting over a satellite network.  
   
   
       4 . A method according to  claim 1 , wherein different display locations utilize different ones of said at least one second channel to modify said first channel.  
   
   
       5 . A method according to  claim 1 , wherein said first channel carries a TV program and wherein said at least one second channel carries advertisements.  
   
   
       6 . A method according to  claim 1 , wherein said first channel carries a WWW site and wherein said at least one second channel carries personalizations of said site.  
   
   
       7 . A method according to  claim 6 , wherein said personalization comprises a scrolling of an object in said site.  
   
   
       8 . A method according to  claim 6 , comprising assigning a third channel for use as a base image channel for said display unit, responsive to an interaction with said WWW site.  
   
   
       9 . A method according to  claim 6 , comprising modifying an interactivity level of said site responsive to an availability of channels.
