摘要： A method and system for detecting and replacing spurious motion vectors in video signal compression includes determining whether a motion vector of a current macroblock is spurious by comparing the motion vector with motion vectors of motion vectors of neighbouring macroblocks; and replacing the motion vector as spurious if the difference exceeds a predetermined threshold. In particular, the method and system seeks to determine (72, 73) whether at least one cluster of motion vectors of neighbouring macroblocks can be formed; and if not, leaves (80) the motion vector of the current macroblock unchanged but if so determining (74) whether the motion vector falls within a cluster. The motion vector may be replaced (81) under certain criteria if the motion vector does not fall within a cluster of motion vectors of neighbouring macroblocks.

摘要： An apparatus for automatically detecting and selecting between progressively scanned and interlaced signals has an input video signal 11 applied to a progressive frame detector 12, a de-interlacer 14 and a compensating delay 13 which has the same latency as the de-interlacer 14. The progressive frame detector determines if the input video signal is an interlaced signal or a progressively scanned signal. If it is determined that the applied signal is interlaced, then output from the de-interlacer 14 is selected. If, on the other hand, it is determined that the applied signal is progressively scanned, then the input video signal is selected after passing through the compensating delay. In both instances, the selected output is a progressive video signal 19 which may be transmitted if the device is used in an encoder or applied to a display device if the apparatus is used in a decoder.
