4 is a flowchart illustrating a method of operating a portable terminal according to a first embodiment of the present invention.

As shown in FIG. 4, the control unit 180 reproduces contents to be used simultaneously with a plurality of counterparts (S400). That is, in addition to the portable terminal of the present invention, a plurality of other portable terminals reproduce the contents at the same time, and contents reproduced in the portable terminal of the present invention and a plurality of other portable terminals are reproduced by the same sync. Accordingly, it is also possible to coordinate or change the syncs between the portable terminal of the present invention and the portable terminals of a plurality of other parties. The content may be an on-line lecture provided through broadcasting contents provided through a broadcasting service, a web site, or the like, and may include a moving picture to be reproduced with the same synchronizing. Accordingly, the content may be the content transmitted through the broadcast receiving module 111 or the wireless Internet module 115 in general.

The user of the portable terminal of the present invention and a plurality of other parties can exchange opinions with each other by using a text message or a chat message while watching the contents reproduced by the same sync.

Next, when there is a reason that the content to be reproduced can be stopped, the control unit 180 temporarily stops the content to be reproduced (S405). Examples of the reason that the content may be stopped include a failure in the transmission network status of the broadcast receiving module 111 or the wireless Internet module 115, a disturbance due to the occurrence of a communication event, and a playback stop due to a user command.

Next, the control unit 180 stores the temporarily stopped position of the content, and transmits a stop message notifying the temporary stop of the content to the plurality of the opponents through the mobile communication module 113 (S410).

Next, the controller 180 determines whether the paused content is reproducible in step S410 (S415). That is, it is judged whether or not the transmission network status defect is solved or the reproduction start is selected by the user command. As a result of the determination in S415, if the content is not reproducible, the content is temporarily stopped.

On the other hand, if it is determined in step S415 that the content can be reproduced again, the control unit 180 transmits a start message indicating the reproduction of the content to the plurality of counterparts (S420). Next, the control unit 180 determines whether the plurality of counterparts are waiting at the position where the contents are temporarily stopped in step S405 (S425). By transmitting / receiving a predetermined signal to / from the plurality of counterparts, it is possible to check whether all of the counterparts are in a pause state.

If it is determined in step S425 that the plurality of parties are waiting, the control unit 180 reproduces the content from the temporarily stopped position and displays the content on the display unit 151 in step S430.

On the other hand, if it is determined in step S425 that the plurality of counterparts are not on standby, the controller 180 displays a first menu on the display unit 151, (S435). Here, the term " stop period " means from the time point when the content is temporarily stopped in step S405 to the time when the content is immediately reproduced. Next, the control unit 180 determines whether to receive the contents of the content based on the user command (S440). As a result of the determination in step S440, if it is determined that the content of the content is not received, the controller 180 plays the content from the stop period after the stop period regardless of the content during the stop period (S465).

If it is determined in step S440 that the content of the content is to be transmitted, the controller 180 receives the content of the content and stores the content in the memory 160 in step S445. Some contents of the contents can be received from the plurality of counterparts, and can be received from a web server or a broadcasting service server. Next, the controller 180 determines whether to reproduce a part of the transmitted content at present (S450). If it is determined that the current playback is not selected as a result of the determination in step S450, the controller 180 plays the content from the stop period onward (S465) regardless of the content during the stop period. On the other hand, if it is determined at step S450 that the current playback is selected, the controller 180 plays back some content of the stored content, displays the content on the display unit 151, and displays a playback message informing that some content of the stored content is being played back To the plurality of other parties (S455). When all the contents of the stored contents are reproduced, the controller 180 terminates the reproduction of some contents of the contents and transmits a reproduction end message to the plurality of counterparts indicating that the reproduction is terminated (S460). Next, the control unit 180 reproduces the content from the stop period on, regardless of the content during the stop period (S465).

5 is a flowchart illustrating a method of operating a portable terminal according to a second embodiment of the present invention.

As shown in FIG. 5, the control unit 180 reproduces the content to be used simultaneously with a plurality of counterparts and displays the content on the display unit 151 (S500). The contents reproduced in the portable terminal of the present invention and the portable terminals of the plurality of the counterparts are reproduced as the same synchronous.

Next, when the content is temporarily stopped in the mobile terminal of a predetermined one of the plurality of the other parties, the control unit 180 transmits a stop message informing the temporary stop of the content from the predetermined counterpart to the mobile communication module 113 (S505). Next, the controller 180 pauses the content according to the transmitted stop message (S510). The location where the content is temporarily stopped in step S510 is the same as the location of the content temporarily stopped in the portable terminal that transmitted the stop message in step S505.

Next, the control unit 180 determines whether to wait in a pause state based on a user command (S515). For example, the control unit 180 may display a menu on the display unit 151 to select whether to wait or not.

As a result of the determination in step S515, if it is determined to wait in the pause state, the control unit 180 stores the temporarily stopped position in step S510 (step S520). Next, the control unit 180 determines whether the start message informing the reproduction of the content is transmitted from the predetermined counterpart in which the stop message is transmitted in step S505 (S525). As a result of the determination in S525, if the start message is not transmitted, the content is temporarily held in a halted state. On the other hand, if it is determined in operation S525 that the start message has been transmitted, the control unit 180 reproduces the content from the paused position and displays the content on the display unit 151 in operation S530.

On the other hand, if it is determined in step S515 that the standby mode is not selected, the controller 180 displays a menu for storing the contents of the content during the pause period (step S535). For example, the menu for storing the content of the content during the pause period may be a menu for storing the entire content of the content during the pause period, the menu for capturing and storing only the main scene among the contents of the pause during the pause period, Or may be a menu for transmitting the content of the content to the other party through a text message or a chat message during the pause period. Here, the term " stop period " refers to a time period from when a content is temporarily stopped in a predetermined other mobile terminal to a time when a predetermined other terminal plays back the content again. A message immediately before a content is replayed in a predetermined other mobile terminal can be known through a start message transmitted from a predetermined other party. That is, the content is stored from the stopped position until the start message is transmitted from the counterpart.

Next, the control unit 180 stores the content of the content in the memory 160 during the pause period according to the menu displayed in step S535 based on the user command (S540). For example, it may store the entire content of the content during the pause period, or may only store the captured main scene. Next, the control unit 180 reproduces the content temporarily stopped in step S510 and displays it on the display unit 151 (S545). Next, the control unit 180 determines whether the start message is transmitted from a predetermined counterpart that has transmitted the stop message in step S505 (S550). As a result of the determination in step S550, if the start message is not received, the control unit 180 continuously plays the content without executing any other function.

On the other hand, if it is determined in step S550 that the start message has been received, the control unit 180 transmits a content of the content stored in step S540 to a predetermined recipient of the stop message in step S505 (step S555). Next, the control unit 180 determines whether a predetermined message is transmitted from the predetermined counterpart (S560). As a result of the determination in step S560, if no playback message is received, the control unit 180 continuously plays the content without executing any other function. On the other hand, if it is determined in operation S560 that the playback message has been received, the controller 180 temporarily stops the content played in operation S545 (S565). Since the steps S550 to S560 generally occur at substantially the same time, if the content is paused in step S565, the location where the content is temporarily stopped is determined in step S510. In step S540, Lt; / RTI > Next, the control unit 180 determines whether a playback end message indicating that some contents of the content reproduced in the predetermined counterpart mobile terminal has been transmitted is transmitted from the predetermined counterpart (S570). As a result of the determination in S570, if the playback end message is not transmitted, the content remains in the pause state. On the other hand, if it is determined in step S570 that the playback end message has not been transmitted, the controller 180 plays the paused content in step S565 (S575). That is, the content is played back from a position where the content has been temporarily stopped at a step S510, after the stop period in which a part of the content is stored in the step S540.

As shown in FIG. 6, the controller of the first portable terminal and the controller of the second portable terminal reproduce the same contents as the same synchronous and display them on the respective display units (S600). The content may be content transmitted from a broadcast server or a web server, and the first portable terminal and the second portable terminal may access a broadcast server or a web server to play the content.

Next, when the content to be played back on the first portable terminal is temporarily stopped (S605), the first portable terminal transmits a stop message informing the second portable terminal of the pause of the content (S610). The second portable terminal that receives the stop message temporarily stops the reproduction of the content (S615), and selects the content on the basis of the user command (S620). In the case of waiting in the pause state, the second portable terminal stores the temporarily stopped position (S621). If the paused contents can be reproduced again in step S625, the first portable terminal transmits a start message to the second portable terminal to notify that the contents are to be replayed in step S630. The second portable terminal having received the start message transmits a message to the first portable terminal indicating that the portable terminal is waiting in a pause state (S635), and reproduces the content from the paused position simultaneously with the first portable terminal (S640 ).

As shown in FIG. 7, the controller of the first portable terminal and the controller of the second portable terminal reproduce the same contents as the same synchronous and display them on the respective display units (S600).

Next, when the content played back in the first portable terminal is paused (S605), the first portable terminal transmits a stop message to the second portable terminal (S610).
