Abstract

Methods for providing remote access to an application executing on a remote server. A client computer includes a client remote access program that is used to connect to a server remote access program. At the client computer, a client difference program having encoded data indicative of changes to the application since changes were last received from the server computer is generated and transmitted to the server remote access program. At the server computer, the client difference program is executed to update the application and a server difference program is generated having encoded changes to the application since the changes were last received from the client computer. The server difference program is transmitted to the client computer to update the application.

First claim

What is claimed:

1. A method of synchronizing a view of an application between a server computer and a client computer, comprising:
executing a server remote access program on the server computer;
executing a client remote access program on the client computer;
determining, by the server remote access program, changes to the application made by execution of the application;
determining, by the client remote access program, changes to the application made by user inputs received at the client computer;
communicating view data representing the changes to the application over a communication connection between the server remote access program and the client remote access program; and
updating, in accordance with the view data, a display of the application in a user interface presented at the client computer.

2. The method of claim 1 , further comprising establishing the communication connection over a computer network to which the server computer and the client computer are communicatively connected.

3. The method of claim 1 , further comprising encoding the view data in a predetermined format indicative of changes made since a last communication of data representing the changes was received at the server remote access program or the client remote access program.

4. The method of claim 1 , wherein encoded changes are indicative of at least one of a path to the change in the state of the application program, a type of the change, and a value of the change.

5. The method of claim 1 , further comprising:
executing a second client remote access program on a second client computer;
determining changes to the application made by either execution of the application, by user inputs received at the client computer or by user inputs received at the second client computer;
communicating view data representing the changes over respective communication connections between the server remote access program and each of the client remote access program and the second client remote access program; and
updating, in accordance with the data, the display of the application in a user interface presented at the client computer and the second client computer.

6. The method of claim 5 , further comprising encoding the view data in a predetermined format indicative of changes made since a last communication of data representing the changes was received at the server remote access program, the client remote access program or the second client remote access program.

7. The method of claim 1 , further comprising generating the view data in accordance with hardware capabilities of the client computing device.

8. The method of claim 1 , further comprising generating the view data in accordance with access restrictions associated with a user of the client computer.

9. The method of claim 1 , further comprising generating the view data to prevent the transmission of sensitive information to the client computer.

10. A method of synchronizing a view of an application between a server computer and a client computer, comprising:
executing a server remote access program on the server computer;
executing a plural client remote access programs wherein each client remote access program is on a respective one of plural client computers;
determining, by the server remote access program, changes to the application made by execution of the application;
determining, by at least one of the plural client remote access programs, changes to the application made by user inputs received by at least one of the plural the client computers;
communicating view data representing the changes over a respective one of plural communication connections between the server remote access program and each of the plural client remote access programs; and
updating, in accordance with the view data, a display of the application in a user interface presented by at least one of the plural client computers.

11. The method of claim 10 , further comprising establishing the plural communications connection over a computer network to which the server computer and each of the plural client computers are communicatively connected.

12. The method of claim 10 , further comprising encoding the changes as view data having a predetermined format indicative of changes made since a last communication of data representing the changes was received at the server remote access program or at least one of the plural client remote access programs.

13. The method of claim 12 , wherein encoded changes are indicative of at least one of a path to the change in the state of the application program, a type of the change, and a value of the change.

14. The method of claim 10 , further comprising generating the view data in accordance with hardware capabilities of the client computing device.

15. The method of claim 10 , further comprising generating the view data in accordance with access restrictions associated with a user of the client computer.

16. The method of claim 10 , further comprising generating the view data to prevent the transmission of sensitive information to the client computer.
