Efficient capture of computer screens

Efficient capture of computer screens

A method for capture of computer screens in a sequence of frames. A first set of windows appearing in a first frame in the sequence is identified, each window having respective first-frame window characteristics and contents. A description of the first set of windows is encoded, indicative of the ap...

description A method for capture of computer screens in a sequence of frames. A first set of windows appearing in a first frame in the sequence is identified, each window having respective first-frame window characteristics and contents. A description of the first set of windows is encoded, indicative of the appearance of the computer screen in the first frame. In a second frame in the sequence, a second set of windows is identified, having respective second-frame window characteristics and contents, the second set including one or more windows corresponding respectively to one or more of the first set windows. Transformations are determined and applied to first-frame window characteristics of the windows in the first set to generate second-frame window characteristics of corresponding second set windows. A description of the second set of windows is encoded, including the determined transformations, for use in reconstructing the computer screen as it appeared in the second frame.
