An EV(Event Verifier) confirms an ID and a password of the connected DVR, and analyzes attached information. An IDM(Image Display Module) displays a transmitted image on a screen. A UOM(User Operation Module) inputs a user input signal, and performs a function of reproducing and inverse-reproducing the signal. A DIR(Database) stores information of many DVRs.

Description

EMERGENCY IMAGE TRANSMISSION APPARATUS AND METHOD FOR DIGITAL VIDEO RECORDER}

The present invention relates to an apparatus and method for transmitting an emergency video in a digital video recorder. In particular, the video input from the digital video recorder (DVR) transmits the video to a remote place when a specific event occurs so that the remote manager can perform pop-ups while performing other tasks. The present invention relates to an apparatus and a method for transmitting an emergency image in a digital video recorder that can be known through a pop-up window.

Conventionally, there is a method of monitoring at a near and far distance. First, a near-field monitoring method monitors an image displayed on a screen by a DVR at a location where a DVR is located. In response, they have taken action.

In the remote monitoring method, as shown in FIG. 1, a DVR is connected to a communication network capable of remote access, such as a local area network (LAN), a public switched telephone network (PSTN), and a dedicated line, and the DVR is connected to a remote PC through a DVR-specific software. It was connected to control, setting and video surveillance.

However, in the prior art, it is necessary to maintain the connection whenever necessary or continuously for 24 hours, and to check the video or event input, which causes excessive communication cost, and the administrator always monitors the video, which causes waste of manpower. In addition, there is a problem such as causing a waste of resources, because a PC that only monitors independently must be designated.

Therefore, the present invention was devised to solve the above-mentioned conventional problem, and when a specific event occurs, the remote manager can transmit the image to a remote site so that the remote manager can know it through a pop-up window while performing another task. The goal is to provide a way to make it work.

1 is an exemplary view schematically showing a configuration for remote monitoring of a conventional digital video recorder.

Figure 2 is an exemplary view showing a brief configuration of the video transmission device in the emergency in the digital video recorder of the present invention.

3 is an exemplary view showing an operation flow according to the present invention.

********** Explanation of symbols for the main parts of the drawing **********

EL: Event Waiter EV: Event Verifier

IDM: Video Display Device UOM: User Operation Module

DIR: database

In the digital video recorder of the present invention for achieving the above object, the configuration of the emergency video transmission apparatus is a socket communication. EL); An Event Verifier (EV) that checks the ID and password of the connected DVR and analyzes the attached information; An image display module (IDM) for displaying the transmitted image on the screen; A user operation module (UOM) for receiving a user's input and performing functions such as play and reverse play; It is characterized by consisting of a database (DIR) for storing information (ID, password, etc.) of several DVRs.

In addition, the method includes a first step of determining whether a registered DVR is verified by verifying previously stored information upon receiving connection information of a DVR from among connection waits of a digital video recorder (DVR);

A second step of determining whether the connection is terminated or less than a predetermined maximum number of connections according to the determination result of the first step;

A third step of receiving and displaying an image according to the determination result of the second step and determining whether the image is the last image;

According to the determination result of the third step, the third step may be repeated, or the fourth step of ending the connection and returning to the user input waiting state.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is an exemplary view briefly illustrating a configuration for applying the present invention. As shown in FIG. 2, an event waiter that informs a response to an event when an event occurs while waiting for a connection from a DVR is provided. , EL); An Event Verifier (EV) that checks the ID and password of the connected DVR and analyzes the attached information; An image display module (IDM) for displaying the transmitted image on the screen; A user operation module (UOM) for receiving a user's input and performing functions such as play and reverse play; It consists of a database (DIR) that stores information (ID, password, etc.) of various DVRs.

Referring to the accompanying drawings, the operation of an embodiment according to the present invention configured as described above will be described.

3 is an exemplary view showing an operation flow according to the present invention. As shown in FIG. 3, when the event waiter (EL) receives the access information of the DVR during the connection wait of the digital video recorder (DVR), the event waiter (EL) receives the event information of the DVR. Notify (S10 ~ S11), EV reads the information already stored in the database (DIR) of the ID and password of the DVR sent by the EL to determine whether it is a registered DVR (S12 ~ S14). .

As a result of the determination, in the case of illegal access, the message is displayed on the user's screen and the connection is terminated. In order to reduce the network load caused by the network, the invitation value that can be accessed simultaneously is limited in advance.

If the determination result is 10 or more, transmit the standby command and repeat the step S15 again (S16). If the determination result is 10 or less, the EV transmits information to the image display device IDM, and the IDM transmits the EV. After receiving permission from the DVR, it receives the video from the DVR, decompresses it, displays it on the screen, and also displays the attached information (for example, DVR ID, pickling type, time, etc.), usually in the form of a tray icon. When the EA exists but the IDM event occurs, after generating the pop-up window and waits for the user's shutdown command (S17 ~ S18).

Subsequently, it is determined whether the last image is the same or the above step S17 is repeated or the connection is terminated and the user returns to the user input standby state (S19 to S21).

In addition, the user operation module (UOM) performs operations such as play, back play, fast forward, rewind, and stop in the form of a button.

As described above, the method of emergency video transmission in the digital video recorder of the present invention enables to perform the surveillance function of the DVR while using it for other purposes by minimizing the load of the independent dedicated PC necessary for remotely monitoring the DVR. It supports simultaneous connection as many as the number of events of multiple DVRs can be recognized at the same time. Also, by connecting only when an event occurs, it reduces excessive communication expenses due to continuous network connection and the administrator does not always monitor the video. It is effective in preventing waste.
