and extracting the display data from the specific computing resource, the extracting comprising initiating read-out of the display data from the specific computing resource according to the selected display capturing mode. ### Claim 2 (depends on 1) The method for extracting display data according to claim 1, wherein the dynamic selection of the display capturing mode comprises a step A of preparing a display capturing mode capability table. ### Claim 3 (depends on 2) The method for extracting display data according to claim 2, wherein the dynamic selection of a display capturing mode includes: a step B of determining the one or more characteristics of the display data; a step C of selecting, in the display capturing mode capability table, the display capturing mode most adapted to the one or more characteristics of the display data; and a step D of switching to the selected display capturing mode, if it is different from the current display capturing mode. ### Claim 4 (depends on 3) The method for extracting display data according to claim 3, wherein the steps B, C and D are repeated iteratively. ### Claim 5 (depends on 3) The method for extracting display data according to claim 3, wherein the steps A, B, C and D are repeated iteratively. ### Claim 6 (depends on 3) The method for extracting display data according to claim 3, wherein the step B comprises determining the “acceleration characteristic” of whether at least some display data have been generated by 2D/3D acceleration. ### Claim 7 (depends on 6) The method for extracting display data according to claim 6, wherein the acceleration characteristic is obtained by monitoring a 2D/3D acceleration solicitation of a graphics processing unit. ### Claim 8 (depends on 6) The method for extracting display data according to claim 6, wherein the acceleration characteristic is obtained by identifying a predetermined pattern in the display data. ### Claim 9 (depends on 8) The method for extracting display data according to claim 8, wherein the display data comprises a plurality of frames, and the acceleration characteristic is obtained by identifying the predetermined pattern in a sequence of frames. ### Claim 10 (depends on 8) The method for extracting display data according to claim 8, further comprising extracting display data by an alternate display capturing mode compatible with 2D/3D generation to confirm the acceleration characteristic. ### Claim 11 (depends on 3) The method for extracting display data according to claim 3, wherein the step B comprises determining the “protection characteristic” of whether at least some display data are protected from reading. ### Claim 12 (depends on 2) The method for extracting display data according to claim 2, wherein the display capturing mode capability table comprises, for each display capturing mode, at least one of the following features: availability; 2D/3D acceleration support; protected display data support; latency; image quality; and computing resources use.
