Patent US 9,947,367

A state of an application program can be stored and transferred to a remote system. The remote system attempts to recreate the original state of the application program. If the remote system is unable to do so, an image of the state of the application program is obtained, instead. Assignment of control to various functions of an application program is achieved by associating a function (i.e., modifying a parameter) with a user control at a remote location.
