Abstract

Examples of systems and methods are provided for handling remote drawing commands. A system may comprise a buffer module configured to receive, at the system from a remote server system over a remote access connection between the system and the remote server system during a remote connection session, remote drawing commands, according to a drawing command rate, of a remote application running on the remote server system. The buffer module may be configured to store the remote drawing commands. The system may comprise a timer module configured to facilitate sending at least some of the remote drawing commands in the buffer module to a graphics module according to a refresh rate that is less than the drawing command rate. The timer module may be application agnostic.

Claims

1-50. -50. (canceled)

51. A method for handling drawing commands on a client device, the method comprising:

receiving drawing commands at the client device over a network connection;

storing the drawing commands in a buffer in the client device;

monitoring the buffer for a change to the buffer, according to a monitor rate;

detecting the change to the buffer; and

sending at least one of the drawing commands in the buffer to a graphics system in the client device, the at least one of the drawing commands corresponding to the change to the buffer.

52. The method of claim 51, wherein receiving drawing commands at the client device comprises:

establishing a remote access connection with a remote server system; and

receiving remote drawing commands from the remote server system.

53. The method of claim 51, wherein the graphics system is configured to display the at least one of the drawing commands on a local display according to a refresh rate.

54. The method of claim 53, wherein the refresh rate is less than or equal to the monitor rate.

55. The method of claim 53, wherein the refresh rate is less than or equal to approximately 60 hertz.

56. The method of claim 51, further comprising detecting a relationship between two related drawing commands, wherein the at least one of the drawing commands in the buffer sent to the graphics system comprises both of the two related drawing commands.

57. The method of claim 51, wherein the drawing commands comprise at least one of a raster operation, a multimedia frame, and a texture.

58. A client device for handling remote drawing commands, the device comprising:

a processor;

a buffer communicatively coupled to the processor;

a graphics system communicatively coupled to the buffer; and

a memory communicatively coupled to the processor;

instructions encoded in the memory, wherein the instructions, when executed by the processor, are operable to;

receive drawing commands over a network connection;

store the drawing commands in the buffer;

monitor the buffer for a change to the buffer, according to a monitor rate;

detect the change to the buffer; and

send at least one of the drawing commands in the buffer to the graphics system, the at least one of the drawing commands corresponding to the change to the buffer.

59. The device of claim 58, wherein receiving drawing commands comprises:

establishing a remote access connection with a remote server system; and

receiving remote drawing commands from the remote server system.

60. The device of claim 58, the system further comprising a local display, wherein the graphics system is configured to display the at least one of the drawing commands in the buffer sent to the graphics system on the local display, according to a refresh rate.

61. The device of claim 60, wherein the refresh rate is less than or equal to the monitor rate.

62. The device of claim 60, wherein the monitor rate is less than or equal to about 60 hertz.

63. The device of claim 58,

wherein the instructions are further operable to detect a relationship between two related drawing commands,

wherein the at least one of the drawing commands in the buffer sent to the graphics system comprises both of the two related drawing commands.

64. The device of claim 58, wherein the drawing commands comprise at least one of a raster operation, a multimedia frame, and a texture.

65. A non-transitory machine-readable medium encoded with instructions executable by a processing system on a client device, the instructions operable to:

receive drawing commands at the client device over a network connection;

store the drawing commands in a buffer in the client device;

monitor the buffer for a change to the buffer, according to a monitor rate;

detect the change to the buffer; and

send at least one of the drawing commands in the buffer to a graphics system in the client device, the at least one of the drawing commands corresponding to the change to the buffer.

66. The non-transitory machine-readable medium of claim 65, wherein receiving drawing commands comprises:

establishing a remote access connection with a remote server system; and

receiving remote drawing commands from the remote server system.

67. The non-transitory machine-readable medium of claim 65, wherein the graphics system is configured to display the at least one of the drawing commands in the buffer sent to the graphics system on a local display, according to a refresh rate.

68. The non-transitory machine-readable medium of claim 67, wherein the refresh rate is less than or equal to the monitor rate.

69. The non-transitory machine-readable medium of claim 67, wherein the refresh rate is less than or equal to about 60 hertz.

70. The non-transitory machine-readable medium of claim 65, wherein the instructions are further operable to detect a relationship between two related drawing commands, wherein the at least one of the drawing commands in the buffer sent to the graphics system comprises both of the two related drawing commands.
