(Bangalore, India).The following quote was obtained by the news editors from the background information supplied bythe inventors: “BACKGROUND ART“A digital video recorder (DVR) is an electronic device used to record videos and store it in a localstorage device, such as an in-built memory, a disk drive, USB drive, SD memory card, and the like. Thestorage capability of the local storage device is generally limited and therefore a limited amount of videodata can be retained. The DVR may correspond to a dashboard camera (dashcam), a security camerasystem, a surveillance camera system, a drone camera and the like that records the scene through differentangles and stores it in the local storage device. In some applications, the DVR systems are employed torecord everyday occurring events for purpose of monitoring situations such as monitoring everyday drivingbehavior of a driver of a vehicle, everyday monitoring of people entering in a facility, monitoring of traffic ina particular area, monitoring operations in a particular area, monitoring operations of a particular machineryand the like. As the data is captured 24*7 everyday, previous data needs to be deleted or moved to differentstorage devices for creating storage space for recording new video data. These DVRs can be of a greatuse as evidence in an event of an accident, a collision or any other incident that could be of interest.Understanding the incident scene, for example knowing how the vehicle was driven by a human behindthe wheels is of utmost priority considering that most of the accidents are caused by human errors All thedrivers involved in the collision are under suspicion and this causes a lot of ambiguity, loss of money, lossof reputation, loss of time, etc., and many times it might not serve justice to the drivers. In this light, thevideo from these DVRs can provide a means for the drivers and the concerned people to find out who wasat fault during the collision.
