The first to third bit rate controllers 202, 204, and 206 are illustrated. ), Multiplexer 208, interface block 210, and the like.

Referring to FIG. 2, the first bit rate controller 202 uses a predetermined bit rate (eg, 80%, 60%, or 40% of the original data) to set a bit rate (bit rate) of the security image acquired and transmitted from the camera 1 (not shown). %, Etc.), and the second bit rate controller 204 adjusts the bit rate of the security image acquired and transmitted from the camera 2, not shown, to the same preset bit rate, and the third bit rate controller 206. ) Adjusts the bit rate of the security image acquired from the camera 3 (not shown) to the same preset bit rate. As such, it may be desirable to reduce the bit rate of the image data in consideration of the transmission bandwidth in the network, the degree of motion detection in the image, and the visual recognition degree of the motion occurrence.

Next, the multiplexer 208 multiplexes each of the bit rate controlled crime prevention images provided from the first to third bit rate controllers 202, 204, and 206, respectively, and converts them into mixed images.

The interface block 210 modulates the security video data (mixed video data) into a signal that can be transmitted through a network and transmits the same to the Internet broadcast service server 106.

Accordingly, the Internet broadcast service server 106 receives a mixed image of three crime prevention images mixed as a crime prevention image.

Referring back to FIG. 1, the Internet broadcast service server 106 demultiplexes a mixed image (the security image) received from the Internet TV 104 through a network, and separates the image into individual security images, and separates the individual images. Motion detection is performed on each of the crime prevention images, and when the motion is detected in a particular crime prevention image, an event (eg, a violent intrusion, etc.) is regarded as occurring, and the corresponding crime prevention image data is stored in the information DB 108 ( It is stored together with the identifier information of the Internet TV subscriber) and transmits to the mobile communication service server 110 through the network. At this time, when the Internet broadcast service server 106 transmits the security video data to the mobile communication service server 110, the number information of the mobile terminal to which the corresponding security video is to be sent (number information of the mobile terminal previously designated by the user). Also sent with.

To this end, the information DB 108 stores the identifier information of the security service subscriber, the portable terminal number information, the security image data for which the movement is detected, and the like.

Next, the mobile communication service server 110 is a server that provides, for example, a communication service related to mobile communication, various additional services, and the like to the mobile terminal users, and has received security from the Internet broadcast service server 106 through a network. The video data is transformed into mobile video content applicable to the mobile terminal, and the mobile video content is transmitted to the mobile terminal through the mobile communication network 112.

Here, the mobile communication network 112 is a communication network for a mobile terminal that provides a mobile communication service, including, for example, a plurality of base stations, a base station controller, a mobile communication switch, a WAP gateway, and the like. It provides a function of transmitting the mobile video content received from the communication service server 110 to the corresponding mobile terminal by wirelessly transmitting the base station.

Finally, each of the mobile terminals 114/1-114 / n in the mobile terminal group 114 uses mobile communication services (e.g., voice communication service, video communication service, data) using, for example, a communication method such as CDMA or GSM. Communication terminal, etc.), each of which is automatically received at the same time as the mobile image content (security video image) is received from the base station (not shown) in the mobile communication network 112 according to the present invention. Display or store in the memory of the portable terminal.

Therefore, the user of the portable terminal can see the security image automatically displayed on the monitor of the portable terminal or load the security image stored in the memory to detect the exact situation (eg, invasion, etc.) in the home. Whether or not, etc., in real time, and can quickly take the necessary response (e.g., prompt contact to police district, fire department, etc.).

In this case, the mobile video content received by the mobile terminal may include a phone number click item for emergency call, and may be set to automatically call the corresponding phone number when the user clicks the item. The telephone number for the emergency call may be, for example, a police zone around the house, a fire station, or the like.

A series of processes for providing a security service in connection with an Internet TV and a portable terminal using the security service system of the present invention having the above-described configuration will be described.

3 is a flowchart illustrating a process of providing a security service using Internet TV according to a preferred embodiment of the present invention.

Referring to FIG. 3, when a user sets a security mode by operating a remote controller or the like, which is not shown in order to go out (step 302), the Internet TV 104 sets a security standby mode (a standby mode in which the power of the Internet TV is turned off). Elapsed time is counted (step 304).

If it is determined in the step 304 that the elapsed time count value reaches the preset security execution reference time n (step 306), the Internet TV 104 automatically turns on the power, and then A power-on control signal for operating the cameras 102/1-102n is generated and transmitted to each camera. Here, the preset security mode execution reference time is a time that can be arbitrarily changed by user selection, and may be, for example, 1 minute, 3 minutes, 5 minutes, or 10 minutes.

As a result, the power of the Internet TV 104 is turned on, and the security video captured by each of the cameras 102/1-102n is collected through the Internet TV 104 to be transmitted to the Internet broadcast service server 106. The security execution mode is performed (step 308).

Next, a detailed process (detailed process of step 308) in which the security service system performs the security execution mode according to the present invention will be described in detail with reference to FIG.

4 is a flowchart illustrating a detailed process of performing a security execution mode according to a preferred embodiment of the present invention.

Referring to FIG. 4, in accordance with the execution of the security mode, the individual security images acquired through the imaging with each camera 102/1-102n are assigned to respective respective bit rate controllers (e.g., FIG. (202, 204, 206, etc.) of 2 (step 402), and the security image data whose bit rate is adjusted through each bit rate controller is converted into a mixed image through multiplexing in the multiplexer 208 (steps 404, 406). ).

Next, the security image data of the mixed image is transmitted to the Internet broadcasting service server 106 through the network together with the identifier information of the Internet TV 104 (step 408), and in response, the Internet broadcasting service server 106 In step 410, the received crime prevention image (mixed image) is demultiplexed into individual crime prevention images, and motion detection is performed on each of the separated crime prevention images (step 412). The motion detection here may use a general motion detection technique and the like that are well known in the art.

As a result of the motion detection in step 412, if it is determined that there is motion in a particular crime prevention image (step 414), it is recognized as an occurrence of an event and the corresponding crime prevention image is transmitted to the information DB 108 together with subscriber identifier information. It stores (step 416), and transmits the corresponding security video data to the mobile communication service server 110 through the network with the number information of the mobile terminal to be sent (step 418). Here, storing the crime prevention image data in which the motion is detected in the information DB 108 is for the purpose of checking the situation when the follow-up action is necessary.

Subsequently, the mobile communication service server 110 transforms the security video data received from the Internet broadcasting service server 106 into mobile video content applicable to the mobile terminal (step 420), and converts the modified mobile video content into a mobile communication network. The mobile station transmits the information to the corresponding mobile terminal via step 112 (step 422).

As a result, the mobile terminal automatically displays the security image received through the mobile communication network 112 at the same time as it is received or stores it in the memory of the mobile terminal (step 424).

Therefore, the user of the portable terminal can see the security image automatically displayed on the monitor of the portable terminal or load the security image stored in the memory to detect the exact situation (eg, invasion, etc.) in the home. Whether or not) in real time.

Here, the mobile video content received by the mobile terminal may include a phone number click item for an emergency call, and when the user clicks the item, the mobile video content may be set to automatically call the phone number. The telephone number may be, for example, a police station around the house, a fire station, or the like.

Referring back to FIG. 3, the Internet TV 104 counts the elapsed time while performing the security execution mode in the security mode (step 310), and also sets the security waiting time based on the security execution mode time count value (m). ) Is checked (step 312).

As a result of the check in the step 312, if it is determined that the security execution mode time count value has reached the preset crime prevention waiting time (m), the Internet TV 104 generates a camera power off control signal to generate each camera ( 102/1-102 / n), and the TV is turned off. That is, the security execution mode is switched to the security standby mode in which the powers of the Internet TV and the camera are turned off (step 314).

Next, the Internet TV 104 counts the elapsed time while performing the security standby mode in the security mode (step 316), and also checks whether the security standby mode time count value reaches the preset crime prevention execution reference time k. Is checked (step 318).

As a result of the check in the step 318, if it is determined that the security standby mode time count value has reached the preset crime prevention execution reference time k, the Internet TV 104 generates a camera power-on control signal to generate each camera ( 102/1-102 / n), and turn on the TV. That is, the security standby mode is switched to the security execution mode in which the powers of the Internet TV and the camera are turned on (step 320). Processing then proceeds to step 308 described above to repeat the subsequent procedure.

Again, the Internet TV 104 checks whether or not a user operation signal for releasing the security mode is input from a remote control or the like (not shown) (step 322). The Internet TV 104 ends all the security modes (step 324).

In other words, in the security mode according to the present invention, the security standby mode (the mode in which the Internet TV and the camera are turned off) and the security execution mode (the mode in which the Internet TV and the camera are powered on to acquire the security image) are set at intervals. (For example, 1 minute, 3 minutes, 5 minutes, 10 minutes, etc.) repeatedly, and this time interval can be changed by user selection.

Meanwhile, in the preferred embodiment of the present invention, when the security mode is executed, the security image is acquired at a predetermined period (repetitive execution cycle of the security standby mode and the security execution mode) and described as being transmitted to the Internet broadcasting service server. The present invention is not necessarily limited thereto, and the security image may be continuously acquired without transmitting the security mode temporarily and transmitted to the Internet broadcasting service server (only the security execution mode is performed).

In addition, in the preferred embodiment of the present invention has been described by acquiring individual security images through n cameras, multiplexing them, converting them to mixed images, and transmitting them to an Internet broadcasting service server, but the present invention is limited thereto. Of course, it can be set to acquire a security video using only one camera, and to transmit the obtained security video as it is to the Internet broadcast service server.
