The playback unit may be implemented by the multimedia module 181 of the mobile terminal of FIG. 1, and the controller may be implemented by the controller 180 of the mobile terminal of FIG. 1.

Preferably, the simultaneous viewing request may be in the form of a generation request for the simultaneous viewing room. Here, the simultaneous viewing room is a virtual space similar to a chat room (chat room) provided by an existing messenger service server such as MSN, and mobile terminals can log in, and multimedia content (especially, a video) is logged in the simultaneous viewing room. Provides the ability to simultaneously watch on the terminal.

It is preferable that one master mobile terminal and a plurality of slave terminals are logged in to one simultaneous viewing room.

In this case, the control unit of the master mobile terminal and the slave terminal may execute a messenger capable of playing the content, and the control unit of the master mobile terminal is a messenger room capable of simultaneously playing the specific content with other terminals. A simultaneous viewing room may be created at the broadcasting station, and the identification symbols of the content to be viewed simultaneously and the identification symbols of the terminals to be viewed simultaneously may be assigned to the simultaneous viewing room.

That is, the iptv broadcasting station serves as a server for a messenger service, and provides simultaneous viewing room service according to a simultaneous viewing room creation request of the master mobile terminal. In addition, the iptv broadcasting station appoints the user of the master mobile terminal that requests the simultaneous viewing room as the owner of the corresponding simultaneous viewing room. At this time, in order to be appointed as the owner user, a special contract (eg, premium service subscription) between the iptv broadcasting station and the owner user may be required. The iptv broadcasting station may assign the management and use authority for the simultaneous viewing room to the owner user who is a user of the master mobile terminal.

For example, when the master mobile terminal is connected to the broadcasting station, when the user of the master mobile terminal requests the creation of a chat room for simultaneous viewing, the broadcasting station creates the chat room, and the master has a management authority of the chat room. Appoint mobile terminal users.

The user appointed as a deputy may use the master mobile terminal to designate slave mobile terminals to simultaneously watch a predetermined content while connected to the simultaneous viewing room, or log in to the simultaneous viewing room of each slave mobile terminal. Allow / Disallow. In the state where the designated slave terminals log in to the chat room, the owner user may designate specific iptv contents and instruct the simultaneous viewing in the simultaneous viewing room logged-in slave terminals.

Looking at the process of creating a simultaneous viewing room in the system to perform simultaneous viewing from the user's point of view, first, the user of the master mobile terminal is connected to the broadcasting station to perform the simultaneous viewing room.

When performing the room creation, the owner user may set the title of the simultaneous viewing room, the number of viewers, whether public / private (password if private), category, tag item, and room interface skin.

According to the implementation, the owner user may have, as management authority, authority to determine broadcast captions for contents to be viewed simultaneously, viewer management (forced leave, pause chat, and block list management), and authority as chat room owner (save conversation contents, erase conversation contents). (Edit), chat banned words, chat prohibition settings), control of simultaneous viewing (simultaneous viewing, start of simultaneous viewing, pause, replay), other permissions (common menu icon registration, viewing screen window, viewer list window , Chat windows, etc.).

 It is preferable that the simultaneous viewing room also has the function of a general chat room. In the simultaneous viewing room, a file / emoticon / flashcon transfer function, a chat command (emoticon / flashcon hotkey, notification, whisper, etc.) setting function, a nickname change function, a chat window font Settings (font color, font type, font size, etc.) can be performed. In this case, the owner of the simultaneous viewing room may have rights similar to those of the owner of the general chat room.

As one of the methods for the users of the slave terminals to enter (log in) the simultaneous viewing room, the user may enter the simultaneous viewing room on a screen displaying a broadcast program item (existing in a broadcast list, etc.) while connected to the broadcasting station. . In this case, it is preferable to provide a means for notifying that the simultaneous viewing room for the broadcast program exists in the form of a link or the like and inducing entry to the item.

Alternatively, the users of the slave terminals may directly search for and enter a desired one of a plurality of simultaneous viewing rooms created in the broadcasting station. As a parameter for searching for the simultaneous viewing room, a telephone number, a name, a nickname, a broadcast title, a tag, and the like may be used.

It will be described with respect to the simultaneous viewing group control method that can be performed by the owner user in the broadcast system.

In order to match the sync when the content of the simultaneous viewing group is played (adjusting the duration of the program being watched between the simultaneous viewing groups), the owner can control the start of the batch collectively, and the master mobile terminal intermittently synchronizes during the play. You can check and readjust.

In the simultaneous viewing room created in the iptv broadcasting station, it is possible to transmit the content in the form of streaming difficult to store to the logged-in terminals. Simultaneous viewing can be achieved without a separate sync signal (signal for adjusting simultaneous viewing timing) when transmitting in streaming form. In this case, the timing of content streaming is preferably matched to the timing played in the master mobile terminal. In this case, the slave mobile terminal having a connection failure cannot watch the contents during the period of failure, but this should be taken for the convenience of copyright protection and simultaneous viewing.

There are several different approaches to pause / replay during simultaneous viewing.

The first solution is that the master mobile terminal has collective control over the suspend function of all the terminals. In this case, even if the stop button is pressed on the player of the specific slave terminal, it is ignored, or the play is performed by moving to the point being played on the master mobile terminal when playing after stopping.

The second approach is to get consent (or owner's consent) from all users of the simultaneous viewing group when performing the pause function. In this case, when a user presses the stop button on the player, a message is outputted to all the terminals (or the master mobile terminal) playing whether to agree to the stop, and the play is paused when all the users indicate consent. In this case, the consent preferably includes an implicit manner in which the consent is regarded as consent after a predetermined time elapses after receiving the consent request message.

The third solution is to freeze the content being watched simultaneously by all users of the simultaneous viewing group.

Even when playing the paused content again, there are some measures similar to the above importance.

Meanwhile, when the terminals are portable terminals or fixed terminals capable of performing voice and / or video calls, inter-group calls or voice calls between individual users may be performed.

In addition, since the simultaneous viewing room follows the general messenger program, group-to-group (or interpersonal) conversations using text (chat, announcement, whisper) and file transfer EPG information, photos, videos, VODs, items, emoticons, Flashcon, skin, etc.). In this case, the owner user can be given a right to transmit his or her message in the caption of the content to be viewed simultaneously.

Since various methods for copyright protection have been proposed, the proposed methods for copyright protection should be applicable to a broadcasting system according to the spirit of the present invention.

Owner users and other users must purchase copyrighted content through joint purchase, or the owner user must purchase the content with a certain range of redistribution rights. Even in this case, if there is a limit such as the period of play, the number of plays, and the like, the limits should be applicable to the master mobile terminal.

FIG. 5 illustrates a development process when a menu for generating a simultaneous viewing room is selected using the master mobile terminal of the present embodiment.

As shown in the drawing, simultaneous viewing room creation is performed through a predetermined menu setting process. For the simultaneous viewing room to be created, the title, broadcast category, description and tags of the simultaneous viewing room, broadcasting properties, number of people, simultaneous viewing room skins, etc. Can be set using the master mobile terminal.
