Description

MULTI FUNCTION DISITAL VIDEO RECORDER FOR VEHICLE}

The present invention relates to a digital video recorder, and more particularly to a multi-function vehicle digital video recorder that can provide vehicle security, driving safety and passenger comfort.

Recently, due to the rapid development of electronic technology, navigation, digital video recorders (DVR), DVD players, etc. have been miniaturized and installed in vehicles. In addition, commercial transportation means such as buses, subways, taxis are provided with a means for measuring the driving record for the safety of driving, and can analyze the driving record measured in this way to monitor the driving habits and driving records of the driver, etc. .

In general, a DVR installed in a vehicle has a limited function of receiving and storing video signals from a plurality of cameras installed inside or outside the vehicle. Therefore, in the case of installing various devices for the convenience of the driver or passengers, each should be installed separately in the vehicle. In the case of separately installing these devices in a vehicle, the number of devices that can be installed is limited due to space limitations, and there is a problem in that an economic burden is placed on purchasing expensive devices.

The technical problem to be achieved by the present invention is to provide a digital video recorder for a vehicle having a variety of functions for security of the vehicle, passenger safety and convenience.

Another technical task of the present invention is to provide a method for efficiently operating a multi-function vehicle digital video recorder.

Additional information such as advertisements and local information corresponding to the output unit are output through the output means 40. In this case, the advertisement and the additional information are displayed as text at the bottom of the monitor on which multimedia information such as a movie is displayed, only the advertisement and the additional information are displayed by switching the screen, or the multimedia information and the advertisement and the additional information are displayed by splitting the screen. It can also be displayed at the same time.

The digital video recorder includes driving record processing means 50 for recording, processing and storing the driving record of the vehicle on the hard disk. Also in this case, the processed driving record is stored in the hard disk 10.

2 is a view for explaining a vehicle digital video recorder and its operating method according to an embodiment of the present invention.

Referring to FIG. 2, the hard disk 10 of a vehicle digital video recorder according to the present invention may be divided into a plurality of data storage areas. Specifically, the hard disk includes a video signal storage area 11 for storing video signals, a multimedia storage area 12 for storing multimedia data such as movies and music, and a driving record storage area 13 for storing driving records of a vehicle. And an additional information storage area 14 for storing advertisements and additional information including location information.

The image processing means 20 divides the video signals photographed by the plurality of surveillance cameras 21 for each channel and divides the inputs into the encoder 23 or outputs the output means 40 directly, and for each channel. And an encoder 23 for compressing the distributed video signal and a decoder 24 for restoring the compressed video signal.

The advertisement processing means 30 includes a GPS receiver 31 for receiving location information from a satellite, and a comparator 32 for comparing the received location information with a local location stored in the additional information storage area 13. .
