Next, a method of preventing the storage of video call contents during a video call in a mobile terminal according to an embodiment of the present invention will be described.

According to an embodiment of the present invention, the mobile terminal 100 may receive and process a storage protection code, or may generate and transmit a storage protection code to a counterpart. Of course, according to an embodiment of the present invention, the mobile terminal 100 may perform both of the two signal processing methods (a method of receiving and processing a storage protection code and a method of generating and transmitting a storage protection code to a counterpart). have. First, a method of receiving and processing a storage protection code will be described, and a method of generating and transmitting a storage protection code to a counterpart will be described.

4 is a flowchart illustrating a signal processing method in a mobile terminal according to an embodiment of the present invention.

Video content storage described herein may include at least one of recording or capturing and storing a video call.

First, the video call may be connected according to the origination of the video call or the reception of the video call signal (S10). The video call may include a one-to-one video call as well as a multiparty video call. An example of a multi-party video call is multi-party video conferencing.

Meanwhile, the storage protection code may be received through the wireless communication unit 110 while the video call is connected (S20). The storage protection code described herein refers to a control signal that can control the video call content storing function to be deactivated or control the video call content not to be leaked to the outside. In addition, the storage protection code may control to delete the storage file for the content of the video call previously stored.

The storage protection code may be received from the counterpart terminal or may be received from a specific server. In this case, the specific server may generate and transmit the storage protection code that has a request for transmission of the storage protection code from the counterpart terminal.

Upon receiving the above-described storage protection code, the mobile terminal 100 may transmit a response message (Ack) for receiving the storage protection code to the counterpart terminal through the wireless communication unit 110 (S30). The response message may be transmitted through a key operation of the manipulation unit 130 or may be automatically performed at the same time as receiving the storage protection code.

In addition, the mobile terminal 100 deactivates a video call content storage function according to the reception of the storage protection code. Of course, the file storing the contents of the video call of the same counterpart may be deleted (S40). That is, the received storage protection code may deactivate the recording and / or capture function of the video call or the external leakage function of the video call. In some cases, a file that stores contents of a video call with the same counterpart may be deleted. The step S40 may be automatically performed simultaneously with the reception of the storage protection code or by a user confirming the reception of the storage protection code.

In addition, when the video call content storage function is deactivated in response to the reception of the storage protection code, the mobile terminal 100 may notify the user of this in various ways (S50). For example, the information indicating that the video call content storing function is deactivated may be notified by a method of outputting a video signal, an output of an audio signal, or a vibration output. In particular, when the user is notified of the information indicating that the content saving function of the video call is deactivated through the output of the video signal, the controller 180 may display a message including information indicating that the content saving function of the video call is deactivated. The information may be displayed on the display module or may indicate that the information storing function of the video call is deactivated. In addition, the information indicating that the content storage function of the video call is deactivated may be notified through the blinking of the LED, or may be notified through the flash image or video.

Next, a method of deactivating a video call content storage function among the signal processing methods in the mobile terminal 100 will be described with a specific example.

5 is a diagram illustrating a state in which a content storage function of a video call is deactivated in a mobile terminal according to an embodiment of the present invention.

As shown, upon receiving the storage protection code, the display module 151 automatically displays the phrase related to the storage protection function setting (FIG. 5A). In addition, a function of preventing storing of video call contents is performed. In addition, an indicator 501 is displayed at the top of the screen indicating that the video call content saving function is being executed (FIG. 5B).

6 is a state diagram illustrating a case where a storage related key signal is input in a video call content storage function deactivation state in a portable terminal according to an embodiment of the present invention.

As shown, when the recording key signal is input while the video call content storing function is inactivated, a phrase indicating that the recording function is disabled is displayed. Therefore, the user can recognize that the displayed text cannot record a video call. Of course, when the capture key signal is input, the phrase that the capture function is impossible may be displayed. The phrase may be displayed to overlap on the displayed image (not shown).

In this case, the recording key signal input and the capture key signal input may be performed by using the same component of the operation unit 130. For example, the recording key signal input may be input by long pressing the camera key, and the capture key signal input may be input by shortly pressing the camera key.

Next, a method of generating a storage protection code in the mobile terminal 100 and transmitting it to the counterpart will be described.

7 is a flowchart illustrating a signal transmission method including a video call content storage prevention code in a mobile terminal according to an embodiment of the present invention.

First, a video call call signal may be transmitted or a video call call signal may be received from a counterpart for video call connection (S110). The video call may include a one-to-one video call as well as a multiparty video call. An example of a multi-party video call is multi-party video conferencing.

In addition, the storage protection code may be transmitted through the wireless communication unit 110 (S120). The storage protection code transmission may be performed while a video call is being attempted to connect. When the video call connection attempt is made, the controller 180 can automatically transmit the storage protection code or receive and transmit a specific key signal.

In addition, a number for transmitting the storage protection code may be set in advance in the mobile terminal 100 to transmit the storage protection code. For example, a screen for automatically selecting an item regarding a video call prevention code transmission may be displayed during a video call connection attempt for a specific number or for a phone number not stored in the phonebook. The specific number may be selected by the user's selection. In addition, the controller 180 may automatically transmit a storage protection code during a call connection attempt for a specific number preset for transmission of the storage protection code or for a phone number not stored in the phonebook.

An example of displaying a screen in the above manner is illustrated in FIG. 8.

8 is a state diagram illustrating a screen for transmitting a storage protection code in a mobile terminal according to an embodiment of the present invention.

As shown, a pop-up window 801 is displayed to select an item related to a video call prevention code transmission during a video call connection attempt for a number not stored in the phonebook. If "yes" is selected in the pop-up window 801, the save protection code is transmitted to the counterpart. The popup window 801 may be displayed to overlap on the displayed image (not shown).

In addition, the mobile terminal 100 according to an embodiment of the present invention may transmit the storage protection code through a key operation of the operation unit 130 during a video call. Key operation of the operation unit 130 may include a specific key signal input (for example, a shortcut key signal input), a soft key signal input (for example, a menu selection displayed on a screen), and the display module 151 is configured as a touch screen. In this case, the method may include dragging an icon or indicator related to the prevention of storing the video call contents to the counterpart image. An example in which the screen is displayed in the above manner is illustrated in FIG. 9.

9 is a state diagram illustrating a screen for transmitting a storage protection code in a mobile terminal according to an embodiment of the present invention.

9A illustrates a state in which a video call connection is attempted. In this case, selecting "Menu" displays a popup window 901 for performing a specific function (FIG. 9B). In the pop-up window 901, a menu (3. Execution of a storage prevention function) for transmitting a storage protection code is displayed. If the pop-up window 901 is displayed and the "3. Execution of storage protection function" is selected, the storage protection code is transmitted to the counterpart. When the transmission is completed, the video call is connected and the screen shown in FIG. 9C is displayed. In this case, when the video call is being connected, the video of the other party is not displayed (shown in FIGS. 9A and 9B), and when the video call is connected, the video of the other party is displayed (FIG. 9C).

In addition, the mobile terminal 100 may have a specific field in the phonebook, so that the specific number may be separately managed such as a spam number or spam mail.

FIG. 10 is a diagram illustrating a state of providing and managing fields related to storage protection in a phone book of a mobile terminal according to an embodiment of the present invention.

As shown, the phonebook is provided with various fields. The phonebook may be efficiently managed using the various fields. In the illustrated phonebook, a field 1001 related to storage prevention is provided. By using the field 1001 related to the storage protection, it is possible to more efficiently manage the storage protection code transmission. For example, by selecting and saving "On" in the field 1001 related to storage protection for a particular phone number, it is possible to always send a storage protection code when a video call connects to the specific phone number, If a number is selected and stored in the field 1001 related to the storage protection for the number, the storage protection code may not be transmitted when the video call is connected to the number.

Meanwhile, a method of transmitting a signal varies according to whether the counterpart terminal to which the storage protection code is transmitted is a storage protection function support terminal or an unsupported terminal. The storage protection function supporting terminal refers to a terminal in which a video call content storage function is deactivated according to the reception of a storage protection code, and the terminal that does not have a storage protection function refers to a terminal in which a video call content storage protection function is not activated even when a storage protection code is received. That is, a terminal that does not have a storage protection function refers to a terminal which does not execute a specific control command even when a storage protection code is received.

As described above, the deactivation of the video call content storing function may include deactivating the recording and / or capturing function of the video call or deactivating the external leakage function of the video call. In some cases, the method may include deleting a file that stores contents of a video call with the same counterpart. It may also include preventing the pre-stored file (including a video and still images) from being played back.

The setting of the telephone number to which the storage protection code is to be transmitted may be stopped only once, and may be maintained even after the video call ends. For example, a mobile terminal that has sent a storage protection code may have the storage protection code sent only when the video call connects to a specific phone number, but only for that video call. When the storage protection code is transmitted once, the "setting" is automatically stored in a field related to the storage protection of the phonebook, so that the storage protection code is transmitted every time a video call is performed.

Meanwhile, the terminal receiving the storage protection code may apply the storage protection code only to the video call, and may automatically delete the storage protection code received when the video call ends, or the storage protection code may be stored in a specific area to perform a video call. You can also have your save-protection code run every time.

First, when the counterpart terminal is a storage prevention function supporting terminal, the counterpart terminal may transmit an acknowledgment message (Ack) to receive the storage prevention code. The mobile terminal 100 receives the response message (S130, S140). The video call may be connected at the same time as the response message is received. When the response message is received, the controller 180 can notify the user of the response message received in various ways. For example, the information on the fact that the response message is received may be notified by a method of outputting a video signal, an output of an audio signal, or a vibration output. In particular, when the user is notified of the information on the response message received through the output of the video signal, the controller 180 displays a message including the information on the response message received on the display module 151 or the Information on the fact that the response message has been received may be displayed as an indicator. In addition, the information on the response message received may be informed through the blinking of the LED, it may also be notified through the flash image or video.

11 is a diagram illustrating a case where the response message is received by the mobile terminal according to one embodiment of the present invention. As illustrated, when the mobile terminal 100 receives a response message for receiving the storage protection code from the counterpart, a popup window 1101 indicating that the response message has been received is displayed. The user may recognize that the counterpart terminal is a storage prevention function supporting terminal through the pop-up window 1101. The popup window 1101 may be displayed to overlap on the displayed image (not shown). In this case, the video call may be connected at the same time as the response message is received.

On the other hand, if the counterpart terminal is a terminal that does not support the storage prevention function, the above-described response message is not transmitted. If the response message for receiving the storage protection code from the counterpart terminal is not received within a predetermined time, the controller 180 can inform the user that the counterpart terminal is the terminal that does not support the storage prohibition function (S150). There may be various ways of informing the fact. For example, the information about the fact that the counterpart terminal is a terminal that does not support the storage prevention function may be notified by a method of outputting a video signal, an output of an audio signal, or a vibration output. In particular, when the counterpart terminal informs the user of the fact that the counterpart terminal is not the storage prevention function through the output of the video signal, the controller 180 may include a message including information on the fact that the counterpart terminal is the non-store prevention function supporting terminal. May be displayed on the display module 151 or information about the fact that the counterpart terminal is a terminal that does not support the storage prevention function may be displayed as an indicator. In addition, the counterpart terminal may inform the fact that the terminal does not support the storage prevention function through the blinking of the LED, or may also be notified through the flash image or the moving picture.

In addition, if a response message for receiving the storage protection code from the counterpart terminal is not received within a predetermined time, the controller 180 may transmit a message for preventing the storage of the video call contents. Of course, the message may be transmitted by inputting a specific key signal (S160). Steps S150 and S160 may be performed both when the response message for receiving the storage protection code from the counterpart terminal is not received within a predetermined time, or only one of them may be performed.

12 is a diagram illustrating a case in which the mobile terminal according to one embodiment of the present invention does not receive a response message for receiving a storage protection code.

As shown, if a response message for receiving the storage protection code from the counterpart terminal is not received within a predetermined time, a popup window 1201 including a phrase including the fact that the counterpart terminal does not support the storage prohibition function is automatically displayed. . In the pop-up window 1201, an item for selecting another function is displayed along with the fact that the terminal device does not support the storage prevention function. In this case, if "1. Send warning message" is selected, a warning message for preventing the storage is transmitted to the counterpart terminal. The popup window 1101 may be displayed to overlap on the displayed image (not shown). In addition, the user may select "2. Alternate video" to transmit another video instead of his own video, or select "3. Voice call switching" to switch to a voice call without transmitting or receiving video. And even if the counterpart terminal is a terminal that does not support the storage protection function, if the video call counterpart is a reliable person, it is possible to continue the video call by selecting "4. Maintain video call".

Meanwhile, the anti-recording message, which is a kind of storage protection code related to an embodiment of the present invention, may be defined in various forms on a specific communication standard. For example, one field indicating recording prevention may be placed in the VendorID message (shown in FIG. 13) or independently defined using a NonStandarParameter (shown in FIG. 14).

As described above, a mobile terminal capable of receiving and processing a storage protection code or transmitting a storage protection code is not limited to the configuration and method of the embodiments described above, but the embodiments may be modified in various ways. All or part of each of the embodiments may be configured to be selectively combined to make it possible.
