DIGITAL VIDEO RECORDER SYSTEM AND OPERATING METHOD THEREOF
First Claim
1. A digital video recorder system, comprising:
- an video recorder unit that records videos in monitoring areas;
a sound input unit that inputs sounds in the monitoring areas;
a DVR device that classifies the sounds for each type by recognizing the sounds in the monitoring areas, stores a recorded video or range information where specific sounds are generated, with the range information consisting of a time or frame information at a point where sound starts generating and a time or frame information at a point where sound stops generating, and accesses the corresponding videos and outputs them to an output device according to the search request of the videos for the specific sounds; and
an output device divided into a display and a speaker, thus outputting videos matching with a specific sound inputted into or transmitted to the DVR device.

Abstract
The present invention relates to a digital video recorder system and a method for operating the same that classifies sounds sensed by a microphone for each type and stores videos in a range where sounds are generated to search the videos for each sound type, thereby making it possible to more rapidly search the videos.
The present invention includes a camera inputting videos; a microphone inputting sounds; a sound video recorder unit that converts videos and sounds input from the camera and the microphone into digital signals; a sound recognizing unit that analyzes sound converted into the digital signals and classifies the sound type; an video managing unit that manages the video in a range where the specific sounds are generated; a sound video file storage unit that manages the range where the specific sounds are generated in an video file and stores it in a database; an video DB that stores the general video recording file; a sound video DB that stores an video file where the sounds are generated; a sound video information DB that stores the information on the video file for each sound type; a sound video searching unit that searches the video file stored in the video DB, the sound video DB, and the sound video information DB according to the search request of the video file; and a sound video display managing unit that is connected to a user interface to provide the search function of the video file and reproduce the searched video file.
