Claim Text:
1. A method for adaptive bandwidth management to handle graphics for a virtual desktop infrastructure (VDI), the method comprising: determining, at a server, that graphics data transmitted to a remote user device has reached a threshold bandwidth; upon determining that the graphics data has reached the threshold bandwidth, detecting video data among the graphics data by using a table to track a number of bitmap blits at window display areas of an application, wherein a bitmap blit is a computer graphics operation in which multiple bitmaps are combined into one bitmap using a raster operator, and wherein the graphics data includes at least some non-video graphics data, wherein detecting the video data by using the table to track the number of bitmap blits comprises recording, in the table, a number of bitmap blits detected in a given window display area during a period, and determining that video data is present in the window display area during the period when the number of bitmap blits recorded in the table exceeds a threshold; and upon detecting the video data among the graphics data, compressing the video data at a higher compression rate than the non-video graphics data before transmitting the video data with the non-video graphics data to the remote user device.
