Abstract: The present disclosure relates to a duplicate image evidence management system for verifying authentication and integrity, the duplicate image evidence management system being capable of verifying that a duplicate image has authentication and integrity when an original image generated by an image storage device is copied by an image collecting device. The duplicate image evidence management system according to the present disclosure includes: an image generating unit for generating an original image; a hash generating unit for generating an original hash value for the original image; a hash checking unit for checking whether the original hash value is changed; and a duplicate image generating unit for copying the original image so as to generate a first duplicate image and generating a first hash value for the first duplicate image, when it is checked by the hash checking unit that the original hash value is not changed.

Abstract: A method of stabilizing a video is provided. The method includes detecting a feature point from a first frame; predicting a location of the feature point in a second frame based on a location of the feature point in the first frame and a predetermined parameter; detecting the feature point from the second frame; determining a distance between the predicted location and a location of the feature point detected from the second frame; and updating the parameter based on a location difference between the feature point detected in the first frame and the feature point detected in the second frame, in response to determining that the distance is within a predetermined threshold.

Abstract: A media playback apparatus and a method including a system for preventing a playback delay are provided. The media playback apparatus may include a delay detecting module to detect a playback delay. The playback delay detection may determine a delay caused by a network, decoding and rendering through a single measurement. When the playback delay occurs, it may be possible to eliminate the playback delay by requesting that a server provide media data having a changed profile. Since the playback delay can be determined through a single measurement of a plurality of playback delay factors, it may be possible to simply and stably perform media playback in a manner suitable for a non-plug-in environment.
