Recording data reproducing device and method on digital video recorder

Abstract

A device and method for reproducing video data on a digital video recorder, which records captured images into data files, and additionally records identification information indicating that it is during the implementation of daylight saving time or during the cancellation of daylight saving time on the above data files, and then When performing the reproduction action, referring to the above identification information, a certain time (for example: 1 hour) is automatically added or subtracted from the recording time of the data file, and at the same time, additional information showing whether daylight saving time is implemented is displayed on the reproduced image, so as to This is to clearly distinguish whether the currently reproduced data file is an image captured during the implementation of daylight saving time, or an image captured during the period after the cancellation of daylight saving time, so that the user does not have to check the shooting date and time of the actual video one by one. distinguish. It has the effect that when submitting the image as public evidence, it is not necessary to prepare evidence such as a data file recorded during the implementation of daylight saving time or the cancellation of daylight saving time.

Description

technical field [0001] The present invention relates to a recording data reproducing device and method on a digital video recorder, and more specifically, it relates to recording the video data of images captured for monitoring as a data file (Data File) on a recording medium such as a hard disk (HDD). A device and method for reproducing recorded data on a digital video recorder (DVR: Digital Video Recorder) for reproduction. Background technique [0002] Usually, surveillance cameras are installed in specific places in order to take pictures of relevant areas, such as figure 1 As shown, the monitoring camera 100 is responsible for taking pictures of the subjects in the relevant area, and then outputting them through the digital video recorder 200 installed at a distance. [0003] And, on the above-mentioned digital video recorder 200, the image of the subject captured by the above-mentioned monitoring camera is recorded and stored in a hard disk (HDD) etc. installed inside...

AI Technical Summary

Problems solved by technology

[0010] However, when the recording time of a data file is automatically increased or decreased by 1 hour for reproduction according to whether the daylight saving time is implemented, it is impossible to determine whether the data file currently to be reproduced is an image taken during the implementation of the daylight saving time or an image taken during the daylight saving time The images captured after cancellation are clearly distinguished, so there is a problem that the user must distinguish one by one for the actual recording date and time
