According to an embodiment of the present invention, the controller 110 can manage the plurality of registered accounts together in an on-line state, and the plurality of the logged-in accounts are managed by the main user and the sub- As shown in FIG.

FIG. 3 is a flowchart illustrating a video call account management method according to an embodiment of the present invention. Referring to FIG. 2, a video call account management method will be described with reference to FIG.

Referring to FIG. 3, the controller 110 divides a plurality of accounts for video communication into a main user and a minor user, and logs in (step 200).

For example, the control unit 110 may manage the registered accounts stored in the storage unit 150 together with an on-line state in which they can receive a video call or a message.

That is, under the control of the controller 110, the communication unit 100 can confirm a video call or a message received for each of the plurality of accounts in the on-line state.

Meanwhile, the plurality of accounts may be classified into a main user account and a minor user account. For example, one of the plurality of accounts may be set as a main user account and the remaining accounts may be set as a minor user account.

In addition, the storage unit 130 may store a main user account or a minor user account for each of the plurality of accounts, and the controller 110 may use the account information to store a plurality of registered user accounts Can be managed by distinguishing between the main user and the sub user and having different priorities or usage constraints.

According to an embodiment of the present invention, it is possible to respond to a video call received with a user account logged in as a main user, but a video call received with a user account logged in as a sub-user can be acknowledged but not answered .

That is, the reception of the video call and the reception notification thereof are all possible for each of the plurality of logged-in accounts, irrespective of the main user or the sub-user, but the actual video call is made with the other party in response to the received video call It may be possible only for the main user account.

In addition, other functions other than the above-mentioned response to the received video call, for example, confirmation of the received message, etc., can be performed only for the main user account, and limited for the remaining sub user accounts.

When the communication unit 100 receives the video call, the control unit 110 determines whether the received video call is to be called with the primary user account or the secondary user account (step 210).

If a video call is received in the secondary user account, the control unit 110 receives from the user whether to change the primary user account through the user input unit 145 in operation 220.

That is, in the case of a video call that is called with the secondary user account as described above, reception through the communication unit 100 is possible, but it may be restricted to proceed with a video call with the other user in response to the received video call.

Accordingly, when a video call is received in the secondary user account, the control unit 110 informs the user of the reception of the video call, changes the secondary user account, in which the video call is received, to the primary user account in response to a user request, The display unit 143 or the user input unit 145 so that the user can respond to the user interface unit 140,

When the user changes the sub-user account in which the video call is received through the user input unit 145 to the main user account, the user can respond to the received video call. In this manner, The video call received in the account may be proceedable.

Hereinafter, a video call account management method according to an embodiment of the present invention will be described in detail with reference to FIG. 4 to FIG.

FIG. 4 is a flowchart illustrating a video call account management method according to another embodiment of the present invention. A description of the same method as that described with reference to FIGS. 1 to 3 of the method shown in FIG. 4 will be omitted below .

Referring to FIG. 4, the controller 110 logs in a plurality of registered accounts for a video call (step 300).

As described above, a plurality of accounts managed by the control unit 110 in the on-line state of being logged in may be composed of one main user account and the remaining minor user accounts, and the method of setting the main user account It can be as follows.

For example, if there is one account registered for the video call, the account is set as the main user account and logged in.

In addition, if the number of accounts registered for the video call is two or more, the account that has been set as the last main user account in the previous operation of the video communication apparatus 10 among the above accounts can be continuously maintained as the main user account .

Meanwhile, the control unit 110 may select an account to be set as a main user among the plurality of registered accounts from a user through a menu for setting a main user account.

Referring to FIG. 5, the control unit 110 may display a screen 400 for setting a main user account through the display unit 143.

That is, on the screen 400, information on a plurality of registered user accounts, more specifically name or ID of each account can be displayed, and an account (for example, User 1) may be displayed.

The user may select one of the plurality of accounts displayed on the screen 400 and then select the change button 410 to change the main user account to a desired account.

Referring to FIG. 6, if the user wants to change the main user account to the user 3, the user selects the user 3 among the plurality of accounts displayed on the screen 400 and then clicks the change button 410 to change the main user account .

Accordingly, the user 3 is set as the main user account among the plurality of accounts, and the remaining accounts, that is, the user 1, user 2, user 4 and user 5 accounts are set as the sub user account, .

Whether each of the plurality of accounts is a primary user account or a secondary user account can be stored in the storage unit 130. [

In order to login and manage a plurality of accounts as described above, the controller 110 includes a 'main user account task' for managing the main user account and a 'minor user account task' for managing the minor user accounts 'So that each task can process the logins of each account and manage its affairs.

For example, the 'main user account task' may first check the status information of the main user account after performing the login of the main user account. Next, after the 'secondary user account task' performs login of the secondary user accounts, the current status of the secondary user accounts can be confirmed.

The status of the account may be information related to the corresponding revision stored in the storage unit 130, and may include, for example, a revised call history, a missed call and message, a friend list, and the like.

When all the plurality of accounts are logged in, the control unit 110 confirms whether the video call is received through the communication unit 100 in operation 310.

For example, the control unit 110 may periodically check whether a video call or a message is received for each of the logged-in main user account and the non-authorized user account, May be checked and processed in preference to the receipt for < RTI ID = 0.0 >

More specifically, the control unit 110 confirms receipt of a video call or message for the main user account using the 'main user account task', and the processing for the video call or message for the main user account is the highest priority So that when the above-mentioned event occurs, it can be performed first.

If the video call or message reception event for the main user account does not occur, the 'main user account task' checks whether the status information for the main user account is changed and updates the changed status information )can do.

If the event for the main user account does not occur, the controller 110 can confirm the reception of the video call or message for the secondary user account using the 'secondary user account task'.

The control unit 110 may periodically and repeatedly confirm whether a video call is received for each of the main user account and the secondary user account according to the priority order as described above.

If a video call is received, the control unit 110 determines whether the received video call is a primary user account or a secondary user account (step 320).

If the account receiving the video call is the main user account, the controller 110 responds to the received video call (operation 350).

For example, the control unit 110 receives from the user whether or not a response to the received video call is received through the user input unit 145. When the user requests a video call response, the control unit 110 transmits, via the communication unit 100, And AV data according to image communication can be transmitted and received.

More specifically, the control unit 110 acquires AV data corresponding to a user's video and audio using the camera 141 and the microphone 142 of the user interface unit 140, After receiving the AV data transmitted from the video communication apparatus of the other user through the communication unit 100, the display unit 143 and the audio output unit 144 are connected to the video communication apparatus of the user, So that the received video call is performed between users.

7, when a video call is received in the main user account, the display unit 143 displays a main user account on the screen 400, for example, a video call for calling user 1 set as the current main user is received Can be displayed.

Also, the display unit 143 can confirm to the user whether or not to respond to the video call received on the main user account on the screen 400, so that the user can access the video call through the user input unit 145 Can be selected.

For example, when the user selects the YES button 420 through the user input unit 145, the user's image 430 and the user's image 440 may be displayed together on the screen 400, And a video call can be performed between the users using this.

On the other hand, when the user selects the No button 425, a response to the received video call may be rejected, the rejected incoming call is processed as a 'missed call' and the corresponding information, for example, Time, sender information, and the like may be stored in the storage unit 130.

If the account receiving the video call is a secondary user account, the controller 110 notifies the user of the reception of the video call of the secondary user account (operation 330).

For example, the control unit 110 may notify the user that a video call for calling a secondary user account is being received through the display unit 143 or the like.

More specifically, when a video call calling a secondary user account is received, the 'secondary user account task' transmits a message informing the reception of the video call of the secondary user account to the 'primary user account task' The user account task may cause the display unit 143 to display a popup window or the like informing reception of the video call of the secondary user account.

In step 350, the control unit 110 determines whether the main user account is changed or not. If the main user account is changed to the main user account, the controller 110 responds to the received video call in step 350.

As described above, since the response to the video call received in the secondary user account is limited, in order to respond to the received video call, the called secondary user account must be changed to the primary user account.

Accordingly, the control unit 110 may request the user to change the main user account through the user input unit 145 to respond to the received video call.

9, when a video call is received in the sub-user account, the display unit 143 receives the sub-user account, for example, the user 3, on the screen 400 under the control of the controller 110 It can indicate that the call is being received.

Also, the display unit 143 can confirm to the user whether or not to change the main user to the user 3 in order to respond to the received video call on the screen 400, thereby allowing the user to input the user input unit 145 It is possible to select whether to change the main user.

For example, when the user selects the Yes button 450 through the user input unit 145, the control unit 110 may change the user 3 to the main user account, and the user 1, which is the previous main user account, You can change it to a user account. The information on the main user account changed as described above may be stored in the storage unit 130.

Meanwhile, according to an embodiment of the present invention, when a user requests a change of the main user, the controller 110 may perform authentication for changing the main user account.

For example, if the user enters a password corresponding to the primary user account to be changed and the input password matches the password stored in the storage unit 130, the change of the requested primary user account may be performed .

Referring to FIG. 10, when the user changes the user 3 to the main user account and wants to respond to the received video call, a password corresponding to the user 3 is input on the screen 400 May be displayed.

When the user correctly inputs the password of the user 3 through the user input unit 145, a video call with the other user can be started in response to the received video call.

On the other hand, if the main user account is not changed, the controller 110 processes the received video call as a missed call (operation 360).

For example, if the user does not want to change the called secondary user account to the primary user account to respond to the incoming video call, or if the password entered for the primary user change is incorrect, The rejected incoming call is processed as a 'missed call' and the corresponding information, for example, the date, time, and sender information, may be stored in the storage unit 130.

Meanwhile, the received call history processed as 'missed call' can be provided to the user after the corresponding sub-user account is changed to the main user account.

For example, when the user selects the NO button 455 on the screen 400 shown in FIG. 9, the received video call is processed as a 'missed call' and information on the received video call is stored in the storage unit 130 If the user 3 is changed to the main user account thereafter, 'Missed Call' information for the user 3 may be displayed on the screen 400 as shown in FIG.

11, when the user 3 is changed to the main user account, the control unit 110 reads the account information stored in the storage unit 130 with respect to the user 3, For example, the received date, time, sender information, etc., on the screen 400 and informs the user of the 'absence call' information previously received through the display unit 143 using the information.

Meanwhile, when the user selects the OK button 457 on the screen 400 showing the missed call list, the 'missed call' information for the user 3 stored in the storage unit 130 may be deleted.

According to another embodiment of the present invention, the video call account management method described with reference to FIGS. 4 to 11 can be performed not only for a video call but also for a received message.

That is, the communication unit 100 can receive a message for each of a plurality of logged-in accounts, but the received message can be confirmed only for a main user account.

12, when a message is received in the main user account, for example, the user 1, the control unit 110 displays the message in the main user account (user 1) on the screen 400 through the display unit 143, And notifies the user of the received message, and receives the confirmation of the received message from the user.

When the user selects the yes button 460, the message received on the main user account (user 1) on the screen 400 can be displayed immediately.

On the other hand, when the user selects the No button 465, a message received by the primary user account (user 1) is processed as a 'missed message', and information about the received message, for example, The sender, and the message contents may be stored in the storage unit 130. [

13, when a message is received in the secondary user account, for example, the user 3, the controller 110 displays the message on the screen 400 through the display unit 143 as the secondary user account (user 3) Is notified to the user.

Also, the display unit 143 can confirm to the user whether or not to change the main user to the user 3 in order to confirm the received message on the screen 400, You can choose whether to change the primary user.

For example, when the user selects the YES button 470 through the user input unit 145, the control unit 110 may change the user 3 to the main user account, and the user 1, which is the previous main user account, You can change it to a user account. The information on the main user account changed as described above may be stored in the storage unit 130.

Meanwhile, according to an embodiment of the present invention, when the user requests the change of the main user, the controller 110 may perform authentication for changing the main user account, as described with reference to FIG.

If the user 3 is changed to the primary user account, the message received by the user 3 may be displayed on the screen 400.

On the other hand, when the main user account is not changed, the control unit 110 may process the received message as an 'absent message'.

For example, if the user does not change the received negative user account to the primary user account, or if the password entered for changing the primary user is incorrect, the received message is treated as a "missed message" The information, for example, the date of receipt, time, originator, message content, etc., may be stored in the storage unit 130.

Meanwhile, the received message details processed as 'absent message' may be provided to the user after the corresponding sub-user account is changed to the main user account.

For example, when the user selects the No button 475 on the screen 400 shown in FIG. 13, the received message is processed as a 'missed message', and information on the received message is stored in the storage unit 130 , And thereafter the user 3 is changed to the main user account, a 'Missed Message' list for the user 3 may be displayed on the screen 400 as shown in FIG.

14, when the user 3 is changed to the main user account, the control unit 110 reads the account information stored in the storage unit 130 with respect to the user 3, Absence message 'information such as the date, time, sender, and message contents previously received through the display unit 143 on the screen 400 and informs the user of the information.
