Abstract: The present invention is to provide a method applicable to a player of a network video recorder for accelerating history playback and event locking, wherein the player decompresses a compressed file of recorded images when performing history playback of the recorded images, flags the resulting frames with “changed” or “unchanged”, depending on whether variation in image data traffic between the successive frames reaches a certain degree, and then sequentially plays the images of the successive frames on a monitor at different playing speeds which are set in the player and correspond to the successive “changed” and “unchanged” frames respectively. Thus, not only is the time required for history playback significantly shortened, but also a monitoring person is enabled to rapidly see, from among large amount of played back image data, the small number of images that demand attention and to greatly reduce the time, energy and effort required while monitoring.
