Abstract

The present disclosure relates to systems and methods for selective implementation of progressive display techniques based on a number of frames displayed in a window. A first hooking component identifies for a window displaying first application data on a local computing device a number of frames to be displayed in the window. A display manager generates, based on the identified number of frames to be displayed, an instruction to compress an identification of an update to the application data. The data is compressed and sent and transmitted to the local device in order to be displayed on the window. A display manager may determine for another window displaying a different application data on the local device whether or not to compress a second identification of an update to the second application data. The second application data may be transmitted to the local device compressed or not compressed based on the determination.

5. The method of claim 1, further comprising determining, by the display manager, that a frame rate of the first application output data has changed.

6. The method of claim 5, further comprising generating, by the display manager, an instruction for the remote agent to compress the identification of the update to the first application output data in response to determining that the frame rate has changed.

7. The method of claim 1, wherein the first hooking component, the second hooking component and the display manager are functions within a driver executing in connection with a non-desktop composited system.

8. The method of claim 1, further comprising:

determining, by a display manager, based on the information identifying the number of frames that a frame rate of the first application output data has changed;

24. The system of claim 4 wherein the display manager further comprises means for determining, responsive to the identified number of frames displayed in the first window in the period of time, for a composited desktop displaying output data on the local computing device, to direct the compression of an update to the output data generated by a remote desktop window manager executing on the remote computing device.

9. A method for selective implementation of progressive display techniques, based on a number of frames displayed in a window, the method comprising:

identifying, by a first hooking component, for a first window displaying first application output data on a local computing device, a number of frames to be displayed in the first window in a period of time, the first application output data generated by a first application executing on a remote computing device;

compressing, by a remote agent, an identification of an update to the first application output data generated by the first application;

transmitting, by the remote agent, from the remote computing device to the local computing device, the compressed identification;

determining, by a display manager, for a second window displaying second application output data on the local computing device, whether to compress or not to compress a second identification of an update to the second application output data generated by a second application executing on the remote computing device; and

transmitting, by the remote agent, from the remote computing device to the local computing device, the second identification of the update to the second application output data generated by the second application, the second identification of the update to the second application output data compressed or not compressed based on the determination by the display manager.

10. The method of claim 9, further comprising determining, by the display manager, to compress or not to compress the second identification of the update to the second application output data in response to identifying the number of frames displayed in the first window in the period of time.
