A system (101) and method are provided for extracting semantic events from a digitised audio-visual sequence (504) depicting sporting events. The system (101) comprises digitised audio-visual sequence input means (206,207,211,212), memory means (209), data processing means (208), and data outputting means (206,207,211,212). Said memory means (209) stores instructions (503), which configure said processing means (208) to filter (304) said digitised audio-visual sequence (504) according to first image data processing criteria (403) to generate first output audio-visual data (506,507). Said instructions (503) also configure said processing means (208) to process (701,702,703) said first output audio-visual data (506,507) to generate second audio-visual data processing criteria (809,914,1016,1207) and filter (704) said first output audio-visual data (506,507) according to said second audio-visual data processing criteria to generate second output audio-visual data (513). Said instructions (503) also configure said processing means (208) to output (306) said second output audio-visual data (513) with said data outputting means. |
