According to the present invention, a standalone type DV board is mounted at a position where a motherboard of a computer case is installed, and the image data received by being connected to an external camera is transmitted to a video processor through a decoding operation to be processed and transmitted to the video processor. The data is output to the LCD monitor or the CRT monitor after encoding. The video processor is connected to the MCU so that the data can be transmitted over the Internet, stored in a USB memory, or recorded on a CD-RW. The MCU uses MUX. By outputting data transmitted from a plurality of input lines to a single output line to be compressed and stored in the hard disk drive (HDD).

The existing PC-based DVR device is a product that is implemented as a general PC card type, and it is cheaper than other products, and it is an advantage that it is easy to build a DVR system by using a personal PC, but the stability of the PC depends on the stability of the entire DVR system. Increasingly, the use of standalone DVR devices that can be easily operated by the remote control is increasing due to users who may affect and feel difficulty in using the mouse.

The standalone DVR is a form of an independent DVR system based on a separate main board capable of performing purely a DVR function. It is a product designed to perform necessary functions with only necessary parts, excluding unnecessary parts used in general PC-based DVR, and is much more stable than the PC-based DVR.

However, since stand-alone DVRs also have their own system, they use dedicated parts, and many of them are costly and time-consuming to develop.

In addition to the above problems, PC-based DVR devices and stand-alone DVR devices were not compatible with each other, and the stand-alone DVR board could not be mounted on a computer case, and the board was interlocked with a power supply and an external device of the computer case. There was also a problem of lack of compatibility and extensibility.

An object of the present invention devised to solve the above problems is to make the same size and shape as the motherboard so that the stand-alone type TV board can be mounted at the position where the motherboard of the computer case is installed and interworked with external devices It can be connected to the power supply of the computer case and to the hard disk drive and CD-RW, and to the board by connecting an external camera to record video, adjust the screen to enlarge, edit, play, and connect to the Internet. It is possible to transfer the data of the image and to recover the data in the self-diagnosis system when the error of the data occurs, the data can be stored in the USB memory or recorded on the CD-RW and stored on the hard disk drive, Can use mouse and remote control at the same time The advantage of having a PC-based DVR devices and stand-alone device such as DVR increasing the convenience to provide a DVR board mountable stand-alone device in the computer case.

Referring to the configuration of the stand-alone DVR board device that can be mounted to the computer case according to the present invention for achieving the above object, the board is formed in the size and shape of the motherboard of the computer position where the motherboard of the computer case is installed A video processor (12) mounted on the board and connected to an external camera (10) to a board mounted on the computer case to receive and decode the image data of the external camera, and receive and process the decoded data; The video processor unit encodes the data to a DVI (Digital Video Interactive: technology for compressing and restoring a moving image) unit 16 for outputting the processed data to the LCD monitor 17 and outputs the encoded data to the CRT monitor 15. A CVBS (Composite Video Baseband Signal) section 14 for making a signal; Receives the data processed by the video processor unit 12 and connects to the Internet to transfer the data and control the data to be recorded on the USB memory 23, CD-RW 26 and the hard disk drive 30. MCU (Micro Controller Unit) unit 18; A RTC (Radio Text Channel) unit 19 connected to the MCU unit to display a date, time, and event of data processing; and using an external camera 10 connected to the board. The operations of processing and controlling data such as generating video / audio data, editing, reproducing, and searching the data can be operated by a mouse or a remote controller of a computer.

Hereinafter will be described in detail with reference to FIGS.

1 is a block diagram showing a connection with other devices when the present invention is mounted on a computer case.

Referring to FIG. 1, the standalone type DV board is made into the size and shape of the computer's motherboard and mounted at a position where the computer case's motherboard is installed and can be interlocked with an external device. By connecting the board to the power supply of the computer case and connecting to a hard disk drive and CD-RW to overcome the problems of system stability and performance limitations caused by the computer's built-in operating system and connecting an external camera to the board. Record video, adjust video screen to enlarge and edit, play back to monitor, and connect to the Internet to transfer the video data, save the data to USB memory or record to CD-RW and hard disk drive (HDD) Stored.
