Description

TECHNICAL FIELD [0001] The present invention relates to a video recorder capable of locally controlling a remote video recorder, and a control method thereof. [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video recorder capable of locally controlling a remote video recorder and a control method thereof and, more particularly, to a video recorder and a control method thereof, in which a plurality of video recorders are connected on a network, So that the remotely located video recorder can be controlled as if it is locally located, so that the user can conveniently use the video recorder locally without having to go remotely. ≪ / RTI >

In recent years, a network video recorder (NVR, Network Video Recorder) which connects a DVR to a network and stores an image transmitted from the camera has been mainly used in the past, in which a video camera is connected to a digital video recorder ) Are the mainstream. In this case, the NVR / DVR generally connects an analog or IP camera or registers it on the network so that the live view, live recording, or recorded video of the camera is played back A video recorder that can be set up.

On the other hand, due to the widening of the wired / wireless network environment and the development of the multimedia compression technology, various kinds and uses of video surveillance systems, surveillance cameras or video recorders are connected to the wired and wireless Internet, To store it. For reference, the live view means that the video is monitored in real time, the video recording (recording) means that the video is recorded on the storage medium, and the playback means that the recorded video is played (played) But a video surveillance system or video recorder substantially includes live view, recording, playback, or a combination thereof and has an equivalent meaning.

Depending on the network environment, video surveillance is generally divided into multiple video recorders or cameras (IP cameras) by using central management software (CMS) or video management software (VMS, Video Management Software) Register and operate integrated operation.

At this time, the VMS / CMS generally connects some functions of the video recorder and the IP camera (live view, playback, etc.) and register the IP camera to operate the plurality of video recorders and cameras centrally Support. When a video recorder and an IP camera are connected to each other in a VMS / CMS, it is not necessary to support all the functions of the video recorder and the IP camera, but it is generally required to support essential functions due to the complexity of the system.

However, when remotely operating a video recorder with a VMS / CMS, it is ideally the ultimate goal of the user to operate exactly as it is directly in front of the video recorder.

If the ability to manage and control the video recorder can be performed remotely without having to change any of the functions of the actual video recorder, that is, without operating the actual video recorder, If possible, the video recorder will be even more usable. It is a core technical idea of the present invention to achieve this object.

For example, if there is a video recorder that monitors and manages each of a plurality of security guard stations, each video recorder generally registers at least one camera installed in an area where the guard station (surveillance site) is located and is used for security surveillance . The central control center manages each video recorder and camera using VMS / CMS. For example, if there is no security guard who manages the security guard at a specific time due to cost, manpower, etc. for some security guard, it should manage using VMS / CMS. At this time, if the guarded video recorder can operate other video recorders like a local video recorder, it is obvious that the cost and cost reduction effect is great. In addition, most VMS / CMS functions operate and manage multiple video recorders. If a particular video recorder can interoperate with another video recorder as if it were operated by the operator (user), this would also reduce costs and save money. It is expected.

Therefore, according to the related art, there is a problem in that when a problem occurs in a video recorder installed in a remote place, or when an operator is not present at a place, the user directly visits the relevant place and operates the video recorder to process the work.

Accordingly, in the present invention, when a plurality of video recorders are connected to a network, each video recorder can control another video recorder in the same manner as a local video recorder, So that the user can conveniently use the video recorder locally without having to go remotely.

In addition, each video recorder 100 receives video data from a plurality of IP cameras and performs live view, playback, recording, streaming, or a combination thereof.

For example, the specific video recorder 100 (b) can not only live view, record, or reproduce a video of a local camera, but also can be used as a live view, For example. The configuration information of the remote video recorder 100 (a) must be set in order to stream the video stream from the remote video recorder 100 (a). That is, the remote configuration information is transmitted to the local video recorder 100 (b) from the remote video recorder 100 (a) to the local video recorder 100 (b) So that the recorder 100 (b) can record the video stream or display it in live view. The local video recorder 100 (b) records the video data received from its locally connected camera in the remote video recorder 100 (a) in the manner of recording in the local video recorder 100 (b) But it may be preferable to transmit and record via the streaming module of the remote video recorder 100 (a).

The local and remote video recorders can record, live view or play back a video stream that has been transmitted remotely, respectively, and can be streamed to another video recorder depending on needs or settings. Therefore, in each video recorder, the video stream can be transmitted from a specific video recorder to another video recorder via another video recorder simply by setting a transmission / reception port or IP address for input / output data of each functional block.

Assuming here that one particular video recorder is local, the other video recorder except the local video recorder is a remote video recorder.

Among the above function blocks, the live view, playback, streaming, and recording function blocks (modules) are accessed using the IP address of the remote video recorder and the registered ID in the specific local video recorder 100 (b) By taking the configuration information of the video recorder, changing it, and then providing it to the corresponding function module of the corresponding video recorder, a particular video recorder can operate as if the remote video recorder were controlled locally.

At this time, video information (stream) as well as configuration information is transmitted between video recorders including live view, playback, res streaming, recording, or a combination thereof.

Hereinafter, how the video recorder 100 according to the present invention is configured to perform the functions described above will be described in detail.

3 is a diagram illustrating a detailed configuration of the video recorder 100 according to an embodiment of the present invention.

3, a video recorder 100 capable of locally controlling a remote video recorder according to the present invention includes a video receiving module 110, a recording module 120, a re-streaming module 130, a live view module 140, a configuration module 150, a reproduction module 160, and an Ethernet module 170. Of course, additional modules (not shown) related to the user interface, storage interface, security, management and operation may be provided. However, since these techniques use known techniques, they will not be described.

In the present invention, each of the functional modules 110 to 160 is connected to an IP camera and an adjacent video recorder through an Ethernet module 170 with an address including an independent IP address, software, or hardware ID. Here, the Ethernet module 170 is an interface for directly connecting to the Internet network.

Accordingly, a video recorder according to an embodiment of the present invention includes a recording module for recording video data in a video recorder, a live view for displaying the video data live, a playback module for playing back the recorded video data, And a function module.

The functional module may further include a video receiving module for receiving video data from at least one camera, and a streaming module for streaming the recorded video data back to the address set in the configuration module and retransmitting the video data.

In addition, the video recorder according to an embodiment of the present invention includes setting an address to receive and transmit the video data to each of the function modules.

The detailed configuration module of the video recorder 100 according to the present invention will now be described in detail.

The video receiving module 110 receives the video shot by the IP camera and outputs the video data to a required destination. For example, when the video data received from the IP camera is transmitted to the video receiving module 110 through the Ethernet module 170, the video receiving module 110 outputs the received video data to a preset destination. For example, the video receiving module 110 may transmit the video data (stream) received by the video receiving module 110 to the recording module 120, the streaming module 130, or the live view module 140 provided in the local video recorder, Lt; / RTI > The video data (stream) transmitted to the streaming module 130 is transmitted to the streaming module 130 as well as the video receiving module 110, the recording module 120, the live view module 140, (130). The video data transmitted through the remote re-streaming module may be used for live view, recording, retransmission, or a combination thereof, in the same manner as the input specification of the IP camera image received by the local video receiving module 110 . Where the streaming module 130 of the other video recorder can be set to the streaming module 130 of another video recorder so that the cascading connection between the video recorders is enabled.

Each functional module according to the present invention can set a source and a destination by designating a separate ID to an address of an independent address or a video recorder, and the setting can be performed according to a designation specified by the configuration module 150 , Independently processes the information input from the origin and outputs the result to the destination again. The present invention is not limited to the IP address but includes a device ID, a process ID, a URI (Universal Resource Identifier), a URL (Universal Resource Locator), or a combination thereof.

Accordingly, the setting of an address in each of the function modules is for controlling the flow of the video data, and the interlocking between the plurality of video recorders is performed by controlling the flow, Since the flow of video data is controlled according to the address set in each functional module of the recorder, it is possible to control the remote video recorder in the local video recorder.

The recording module 120 records (stores) the video data received from the video receiving module 110 in the storage. That is, in the recording module 120, the video stream compressed by the IP camera is received from the video receiving module 110 and stored in the storage. Accordingly, the recording module 120 includes a function of classifying and storing each video according to channel, location, time, and compression method in order to store the received video in the storage. Also, the recording module 120 includes a function of receiving the video stream (data) transmitted from the re-streaming module 130 provided in the other video recorder and storing the received video stream in a predetermined storage.

The storage includes a storage medium on the cloud or a storage device (HDD, virtual space, external hard disk, etc.) installed in a local video recorder. If the storage device is a hardware device having its own storage device, a destination can be designated by a device ID, When using media or virtual memory, specify the address of the storage.

Of course, in the present invention, storing video data by including audio data, voice data, or sensor data in addition to video data is a concept including storing the audio data, voice data, and sensor data.

The streaming module 130 reads a video stream recorded in the storage through the recording module 120 and retransmits (streams) the video stream to the video receiving module 110 of the other video recorder 100 .

If the configuration module 150 is set to reproduce the video recorded in the other video recorder locally, the video data (recording data) transmitted through the re-streaming module 140 in the other video recorder, The reproduction module 160 can reproduce the video data locally. In addition. The playback module 160 of the local video recorder can directly receive and play the video data from the recording module 120 of the other video recorder.

The live view module 140 outputs video data received from the IP camera directly in real time. Actually, the IP camera or the like compresses video in advance and transmits it as an IP packet, so that the Ethernet module receives the IP packet A packet is decoded and then the video is decoded to output the corresponding video to the display screen. However, a typical analog or digital camera without compression will display the original image directly on the monitor screen.

Meanwhile, the playback module 160 plays a role of calling a video recorded in a local storage or a storage on the cloud and playing back the stored video. Also, the video stream recorded by another video recorder can receive the video stream (data) from the streaming module 130 of the other video recorder and reproduce the corresponding video data. It is also possible to receive the video stream (data) from the recording module of the other video recorder and reproduce the corresponding video data directly from the local video recorder. In order to reproduce the video data, an encoded video stream must be reconstructed and reproduced. In addition, if text, sound information, and sensor data added to the video are also present, it should be processed together.

That is, the playback module 160 may transmit the video data recorded in the remote storage or the cloud storage received through the re-streaming module 130 provided in the other video recorder to the playback module 160 provided in the local video recorder And plays a role of receiving and reproducing. As mentioned above, a video stream (data) may be received from a recording module of another video recorder and the corresponding video data may be reproduced by a local video recorder.

Here, the video data player used for the reproduction of the video data in the live view module 140 and the reproduction module 160 can be used commonly or separately.

Hereinafter, a method in which two or more video recorders interlock with each other will be described.

4 is a diagram for explaining a concept of interlocking between video recorders according to an embodiment of the present invention.

As shown in FIG. 4, a process in which the local video recorder 100 and the remote video recorder 100, which are two different video recorders, operate in cooperation with each other is presented.

First, the remote video recorder and the local video recorder are composed of the same module (they may be configured differently, but it is necessary to customize them according to the functional necessity so as to form a combination of the respective configuration modules) It is possible to use the function module as if it is a functional module.

In order to control the operation of the remote video recorder in the local video recorder, the configuration information must be shared with each other.

It is possible to receive the input video data of the IP camera from the video receiving module 110 of the remote video recorder through the sharing of the configuration information and monitor the live video in the local video recorder. That is, the input video data of another video recorder can be displayed live via the live view module 110 of the local video recorder via Ethernet. In this case, the video data of the video receiving module of the remote video recorder is transmitted to the live view module of the local video recorder, and a configuration in which the remote video recorder receives the camera video and transmits it to the listening module of the remote video recorder, Video transmitting module through the network. This is the same as when a camera image is received by a video receiving module and transmitted to a live view module for display.

So, in order to record the camera input image of a remote video recorder in a local video recorder, a remote re-streaming module can be configured to transmit the image to a local video receiving module and record it as if it were a local video data input have. This allows the recording on the local video recorder to be set up so that only the data coming in via the video receiving module is recorded by the recording module. That is, the recording module can be configured to record only the data transmitted through the local video receiving module without directly communicating with the module of the other video recorder. However, since this is an embodiment, it is preferable to configure the video recorder only by setting the source and destination addresses.

In addition, when it is desired to reproduce the video data recorded remotely in the local video recorder, the data recorded (stored) in the remote video recorder is read through the re-streaming module 130 and is reproduced in the replaying module 160 of the local video recorder . Also, as described above, the data recorded (recorded) in the recording module 120 of the remote video recorder may be transmitted to the playback module 160 of the local video recorder and played back.

Hereinafter, a procedure of setting, sharing, and interlocking between video recorders based on the configuration information in the video recorder according to the present invention will be described in detail.

5 is a flowchart illustrating configuration of configuration information of a video recorder according to an exemplary embodiment of the present invention and operation of each configuration module according to the configuration information.

5, each video recorder 100 has an address to which each function module of the video recorder transmits and receives (where the address is an IP address, a device ID, a local host, or a group ID, URL, URI, specific IP address, and IP address of the group including the specific IP). The configuration module 150 sets transmission and reception addresses for the video receiving module 110, the recording module 120, the re-streaming module 130, and the live view module 140 of the corresponding video recorder. Next, the video receiving module 110 receives the video data from the IP camera, and then receives the video data according to whether the destination address is the recording module 120 or the live view module 140, and then displays the live view, It is determined which combination to perform. Here, recording and live view are functions that can be performed individually or simultaneously. The recording module 120 receives the video data from the video receiving module 110 and stores (records) the video data in a storage designated as a destination. In addition, the live view module 140 plays video data received by the video receiving module 110 on a live display screen. The streaming module 130 includes a function of streaming the data of the video receiving module 100 and a function of reading the recorded video data and streaming the data to another destination. That is, the streaming module 130 of the specific video recorder 100 includes a function of retransmitting the data of the video receiving module 110 of the video recorder to the streaming module of another video recorder.

A method of specifying a source and a destination address of each functional module in the configuration module according to an embodiment of the present invention will be described by way of example.

FIG. 6 illustrates an example of a source address and a destination address for each functional module of the video recorder according to the present invention.

As shown in FIG. 6, the source of the video receiving module will be the destination IP address (190.40.52.3) for the specific IP camera. The video receiving module receives the video data at the address, and then transmits the video data to the destination 190.40.52.10 / 01. Then, since the module having the source address of 190.40.52.10 / 01 is the recording module, the video data is transferred to the recording module, and the video data is stored (recorded) in the storage device at the address specified by 190.40.52.10 / 02.

On the other hand, the video data output from the video receiving module is directed to the live view module. The live view module outputs the received video data to a display device at an address specified by 196.40.52.10 / 03.

In this way, the video data received by the video receiving module is recorded on the designated storage through the recording module or outputted on the display screen designated through the live view module.

Also, the video data stored in the storage (e.g., 196.2.60.01/02) may be accessed by the re-streaming module and then transferred to other video recorder's recording module (e.g. 196.2.60.01/01), streaming module (e.g. 196.2.60.01 / 02), a playback module (e.g., 196.2.60.01/02), and the recording module receives the video data and stores it in another storage (e.g., 196.2.60.01/02) Data can be received and transmitted to the res streaming module or the playback module of another video recorder. The playback module also receives the video data and displays it on a display (e.g., 196.2.60.01/03) screen.

A table for such setting information is shown in Fig. 6, which enables interworking between video recorders by sharing the setting information with other adjacent video recorders.

Next, the interlocking operation between the video recorders 100 according to an embodiment of the present invention will be described.

7 is a flowchart illustrating a flow of interworking between video recorders according to an embodiment of the present invention.

As shown in FIG. 7, the configuration module 150 of the local video recorder needs to share configuration information with the configuration module 150 of the remote video recorder so that the configuration module 150 can be interlocked. After both video recorders share configuration information, each of the configuration modules 150 should set an IP address for a source and a destination for each function module of the video recorder to which the configuration module 150 belongs.

The local video recorder and the original video recorder are automatically linked according to the set address.

If the local video recorder wishes to live view video data of the remote video recorder, the destination IP address of the video receiving module 110 of the remote video recorder may be set to the IP address of the live view module of the local video recorder. To do this, the incoming IP address for the live view module 140 of the local video recorder must match the destination IP address of the video receiving module 110 of the remote video recorder.

In addition, when the local video recorder wishes to reproduce the video data of the remote video recorder, the video data recorded through the re-streaming module of the remote video recorder is received and reproduced by the reproduction module of the local video recorder. In addition, the recording module of the remote video recorder may receive the recorded video data (without going through the re-streaming module) and reproduce it on the playback module of the local video recorder.

Next, in order to record the video data of the remote video recorder in the local video recorder, the video data received from the IP camera is received through the video receiving module of the remote video recorder, and the recording (recording) .

Particularly, in the present invention, the video recording may be recorded only on the video data received through the video receiving module 110. This allows the video data of the video receiving module of the remote video recorder to be transmitted to the remote streaming module of the remote video recorder, which is then received by the video receiving module of the local video recorder and then transmitted back to the recording module for recording to be.

Meanwhile, the video recorder according to the present invention may be converted into a video storage server 1100 or a video surveillance terminal 1200, if necessary.

8, the video storage server 1100 includes a video receiver module 110, a recording module 120, a streaming module 130, a configuration module 150, and an Ethernet TCP / IP) module. That is, except for the live view module and the playback module in the video recorder, the configuration for the video storage server 1100 is derived.

The video receiving module serves to receive video data from a plurality of cameras, and the recording module classifies and stores the received video recorders by camera, by time, by user, and by monitoring site. The streaming module also allows cascading from the video storage server to another video storage server to be stored on the appropriate video storage server. In addition, the configuration module sets the source and destination addresses of each functional module.

9 is a diagram showing a monitoring terminal configured with a video recorder according to an embodiment of the present invention.

9, the monitoring terminal 1200 includes a video receiving module 110, a live view module 140, a configuration module 150, and an Ethernet (TCP / IP) module in the video recorder 100 do. That is, the configuration for the surveillance terminal 1200 is derived by excluding the recording module, the res streaming module, and the playback module in the video recorder.

The video receiving module receives video data from a plurality of cameras, and the live view module outputs live video data received through the video receiving module to a display screen. In addition, the configuration module sets the source and destination addresses of each functional module.

Therefore, the video recorder according to the present invention is advantageous in that various types of terminals or servers can be configured by changing the ubiquitous characteristic of each functional module, and changing or newly configuring the channel of the corresponding module.

That is, by setting a network address for transmitting and receiving video data to and from each of the functional blocks in the configuration block, the video recorder can be used as a video storage server, a video surveillance terminal for video surveillance, a video client, At least one can be constructed.

Hereinafter, a process of interworking between a plurality of video recorders according to an embodiment of the present invention will be described.

10 is a flowchart of a method for controlling a plurality of video recorders to interoperate according to an embodiment of the present invention.

As shown in FIG. 10, configuration information is shared among a plurality of video recorders, but the configuration information is continuously shared until there is no remote video recorder to be interlocked. Also, configuration information according to the interworking function between video recorders is prepared. As the number of video recorders to be interlocked increases, the number of nodes to which each video recorder provides the result of processing video data increases. Since the processing results of such video data must be exchanged with each other, the configuration information becomes more complicated as the number of video recorders to be linked increases. However, it is only necessary to process the information received in each function block of each video recorder and manage only the IP address of the node to which the result is to be provided (S100).

This process is repeated until there is no remote video recorder to be interlocked (S200). After all video recorders to be linked are registered, the source and destination addresses for each functional block are set in the configuration module of each video recorder (S300).

Next, each functional block of each of the local and remote video recorders receives video data to the set address (S400), processes the own function (S500), and transmits the processed video data to the set destination address (S600 ). The inherent functions include recording, live view, streaming, playback, and the like.

In the case of streaming among the inherent functions, the destination address of the streaming module in one video recorder specifies the address of the playback module of another adjacent video recorder, and the streaming module of the adjacent other video recorder specifies another adjacent video If the address of the playback module of the recorder is specified, each video recorder provides its recording information to another video recorder for playback.

As such, the video recorder capable of locally controlling the remote video recorder of the present invention enables each video recorder to control other video recorders in the same manner as a local video recorder when a plurality of video recorders are connected on a network, Can be controlled as if it is located locally.

Therefore, the video recorder capable of locally controlling the remote video recorder according to the present invention has an advantage that it can conveniently use the video recorder locally without the user having to go remotely, thereby reducing the operation cost and expense.
