Description

DVB troubleshooter {Troubleshooting apparatus for digital video recorder}

The present invention relates to a digital video recorder (DVR) failure processing apparatus, and more particularly, when an error occurs in a surveillance camera or a television that transmits a captured video signal, an error state data is transmitted through a public data network, and remotely. The monitoring and control center relates to a TV failure processing apparatus that transmits an initialization control command with reference to the failure information data so that the TV device is restored and operates normally.

For various purposes, such as monitoring the abnormal operation of a hazardous materials handling device in an industrial site or crime prevention in an exhibition or a public building, a surveillance camera is used to capture a main surveillance area and display the captured video signal of each channel in sequence or all channels. The surveillance system which divides and displays the image on one monitor screen can be monitored in real time by the administrator, and also records and stores the video signal to select the required recording time point and quickly check it.

A conventional surveillance system records a tape using a video tape recorder (VTR) to record an analog video signal captured and output from a camera installed at a place to be monitored, and a user searches for a recorded tape as needed.

Since the entire section of the tape has to be checked continuously for retrieval of such recorded images, a long retrieval time was required, and the deterioration of image quality and the hassle of replacing the tape by repeatedly recording and replaying analog image signals on the tape. In recent years, the digital video signal of the surveillance camera is compressed and stored semi-permanently on the HDD so that the user can quickly search the recorded digital video data. A PC-based TV device is used by attaching a capture board to a conventional PC board having a multiplexer function capable of dividing and monitoring, and having a video retrieval function capable of monitoring recording and real-time screen.

However, in the past, when a DVR connected to a surveillance camera is operated when the manager of the site is inexperienced, or when the administrator of the site's surveillance system leaves the office when operating in the continuous recording mode for 24 hours, an immediate failure occurs when a failure occurs. There was a problem that it could not record the video channel of the surveillance camera for a long time until the failure was checked because the recovery could not be performed, so that the function as a surveillance system could not be performed smoothly.

The technical problem of the present invention is to transmit the error status data to the remote monitoring center when the abnormality of the surveillance camera and the DVR is checked, and the initialization control command according to the symptom of the failure in the remote monitoring center to the subscriber's TV failure processing unit. The present invention provides a device for preventing disturbance of a TV that normally recovers the operation of a corresponding connected device.
