  • (a) receiving, by an agent executing on a server, display update information generated by an application executing on the server;

    (b) creating, by the agent, a first encoded display update by applying a first encoding to the display update information;

    (c) transmitting the first encoded display update to a client communicating with the server over a network having an amount of bandwidth;

    (d) detecting, by the agent, a change in the amount of bandwidth;

    (e) creating, by the agent responsive to detecting, a second encoded display update by applying a second encoding to the display update information, the second encoding using data redundancies of the display update information to reduce the amount of graphical data; and
