3A is a flowchart illustrating a method of moving a broadcast channel using a key button according to an exemplary embodiment of the present invention, and FIG. 3B is a diagram illustrating a multimedia data display screen according to an exemplary embodiment of the present invention.

In the channel type VOD service according to the present invention, a user does not need to select a desired channel in a complicated tree structure in order to move to a desired channel among a plurality of channels, and uses a key button provided in the user terminal 110 to correspond to the corresponding channel. By inputting a predetermined number or by using the left and right direction keys has a feature that can be easily moved to the desired channel.

Referring to FIG. 3A, when a user inputs a predetermined function button to receive multimedia data, in step 310, the user terminal 110 may designate an application (ie, a multi-vision application) that allows the user to use multimedia data. ) And displays an intro screen (see 380-FIG. 3B) on the display unit. In this case, when the user sets the channel setting function using the channel setting window (see 260-FIG. 2B) as described above, the multimedia automatically switched to the most recently used channel and provided through the corresponding channel. Data may be displayed on the display of the user terminal 110. In addition, the intro screen is such that only representative channels (eg, KMTV, SBS, KBS, MBC, etc.) are stored in the user terminal 110 storage unit, and the intro screen for a new channel or other channels is displayed in the multimedia server 120. 3), the intro screen 380 may include a data display area 383, a channel display area 385, a function button area 390, and the like. It may include.

The data display area 383 is an area for displaying multimedia data (for example, broadcast data, movie data, etc.), helper images, text data, and the like corresponding to the channel information displayed on the channel display area 385. Channel display The area 385 is an area for displaying channel information (eg, channel number, channel name, etc.) input or selected by the user, and the user can enter a key button (eg, numeric keys, etc.) of the user terminal 110. It is possible to input and select channel information by using a direction key.

The function button area 390 may include a menu button, an operation button, a stop button, and the like. The user may change the setting state of the multimedia data, determine the exposure of the helper, or determine the multimedia data using the function buttons. In operation 315, the user terminal 110 (that is, the currently operated multi-vision application) may perform a key button for changing a channel from the user. Check whether numeric information is input using.

As a result of the check in step 315, if the user inputs numeric information to change the channel, the flow proceeds to step 320 to check whether the predetermined time has elapsed while the number is input and no other number is input. .

Of course, the process of steps 315 to 320 relates to the case where the user inputs only a part of the channel number, and the process may be omitted if the user inputs the entire channel number. That is, it can be applied similarly to the case where the user changes the channel using the television remote control.

For example, the user terminal 110 inputs a channel based on the current input value if there is no input for a predetermined time (for example, 3 seconds) after the user inputs a specific channel number (for example, 6 inputs). Perform a move (e.g., move the channel to 006).

In addition, after the user inputs only a part of the channel number, the operation button (ie, the Play button) of the function button area 390 included in the intro screen 380 (or the multimedia data display screen 580-FIG. 6). ), Multimedia data (or broadcast data, etc.) provided corresponding to the channel number may be displayed on the display of the user terminal 110. On the contrary, if the user selects the operation button a predetermined number of times (for example, once or twice) while watching the multimedia data corresponding to the newly switched channel number, the user enters the intro screen 380. You can also make it return.

If the specified time has elapsed as a result of the check at step 320, the process proceeds to step 330, but if the specified time has not elapsed, the process waits until the time specified at step 320 has elapsed. In FIG. 3B, when the predetermined time has not elapsed as a result of the check of step 320, only the case where the user waits in step 320 until the time elapses is illustrated, but it is checked whether a new number or a direction key is input from the user. Obviously, the user terminal 110 checks whether the numeric information input through the step 315 is valid channel information. In the case of valid numeric information, the process proceeds to step 335 and transmits the channel information to the multimedia server 120 through the communication network. However, if the numerical information is not valid channel information as a result of the check in step 330, the flow proceeds to step 333 and displays an error message (for example, the inputted channel number is not valid) on the display of the user terminal 110. And terminate the step (of course, it may automatically switch to the previous channel).

Validation of the channel information performed in step 330 may be performed based on whether the channel information stored in the storage of the user terminal 110 and the channel information (eg, numeric information) input by the user match. (I.e. how to save the channel list locally). Of course, if the user terminal 110 unconditionally transmits the numeric information input from the user to the multimedia server 120 side, the multimedia server 120 performs the validity check of the corresponding channel information and then sends the appropriate multimedia data or an error message to the user terminal ( The method of transmitting to 110 may also be applied (that is, the user terminal 110 registers only the channels mainly used by the user (favorite function), and the entire channel list is managed by the multimedia server 120). In addition, the channel list is stored in the storage of the user terminal 110, but when a new channel is generated, the above-described two methods are performed in parallel, such as a method of resolving through synchronization of the user terminal 110 and the multimedia server 120. The method may also be applied.

Referring back to step 315, if the user has not entered numeric information for channel change, the process proceeds to step 325 to check whether the user has input a direction key.

As a result of the check in step 325, if the user inputs a direction key for channel change, the process proceeds to step 330 to check whether the newly changed channel information is valid channel information. Of course, when the user wants to change the channel information using the direction key, the channel can be changed only within the channel list stored in the user terminal 110. In this case, the newly changed channel information (for example, If the existing channel is 007, the process of checking whether the 006 or 008 channel changed by the input of the direction key) is valid channel information can be omitted.

Thereafter, the multimedia server 120 receives channel information input by the user from the user terminal 110 in step 340, and proceeds to step 345 to store multimedia data corresponding to the received channel information in the multimedia server 120. The search is performed by the unit 135 and transmitted to the user terminal 110 through the communication network (step 350). Of course, if the subject providing the multimedia data corresponding to the channel information is the external content server 150, the multimedia data received from the content server 150 after transmitting the data providing request to the content server 150 The user terminal 110 may receive the multimedia data corresponding to the channel information transmitted through the step 335 from the multimedia server 120 in step 355. In operation 360, the multimedia data received in operation 355 is displayed on the display of the user terminal 110.

In addition, while the multimedia data (or broadcast data, etc.) is being displayed, the user may proceed back to the previous step by using the cancel button provided in the user terminal 110.

For example, when the user selects a cancel button while the initial screen 210-FIG. 2A is displayed on the display unit of the user terminal 110, the multivision application may be terminated.

In addition, when the user selects the cancel button while the multimedia data is being displayed on the display unit of the user terminal 110 (that is, during VOD streaming), the user can switch to the intro screen (see 380-FIG. 3B). have.

In addition, when the user selects the cancel button while the intro screen 380-FIG. 3B is being displayed on the display of the user terminal 110, the initial screen 210-FIG. 2A may be displayed. .

4A is a flowchart illustrating a method of reproducing a multimedia data of a menu tree method according to another exemplary embodiment of the present invention, and FIG. 4B is an exemplary view of a screen display when reproducing multimedia data of a menu tree method according to another preferred embodiment of the present invention. to be.

In describing the menu tree type multimedia data reproduction method shown in FIG. 4A, an exemplary view of the screen display shown in FIG. 4B will be described together for convenience of understanding, and the same steps are the same for both drawings. An identification number will be used.

Referring to FIG. 4A, when a user inputs a predetermined function button to receive multimedia data, in step 410, the user terminal 110 may designate an application (ie, a multi-vision application) that allows the user to use multimedia data. ) And displays an intro screen 410-FIG. 4B on the display unit.

In operation 415, the user terminal 110 (ie, the multimedia application) may determine whether predetermined information (eg, channel 000 or a menu button) is input from the user using a key button provided in the user terminal 110. Check it. That is, the user terminal 110 checks whether or not predetermined information (for example, channel 000 or a menu button) is input by the user while the screen 410 of FIG. 4B is displayed on the display unit. As a result of the inspection, if predetermined information is input by the user, the flow proceeds to step 420 to transmit the information input by the user (or a request for transmitting menu information corresponding to the predetermined information) to the multimedia server 120 through the communication network. do. However, if the information specified in advance by the user is not input as a result of the check in step 415, the process waits in step 415 until the corresponding information is input (of course, other channel information is selected by the user and the corresponding channel information is inputted to the corresponding channel information. Other operations such as displaying corresponding multimedia data are also possible).

In operation 425, the multimedia server 120 receives input information (or a menu information transmission request previously designated to correspond to the input information) input by the user from the user terminal 110 through a communication network. In operation 430, menu information corresponding to the input information (or menu information transmission request) received in operation 425 is searched in the storage unit 135, and then the searched menu information is transmitted to the user terminal 110 through a communication network. The user terminal 110 receives menu information from the multimedia server 120 through the communication network in step 435, displays the received menu information on the display unit, and proceeds to step 440 to select information about specific multimedia data from the user. Get input.

An exemplary view of the screen display when the menu information is received from the multimedia server 120 and displayed on the display unit of the user terminal 110 is illustrated on the screen 435a of FIG. 4B.

Referring to screen 435a of FIG. 4B, menu information that allows a user to select a specific channel is configured in a tree format, and includes a main menu (eg, Movie Today, Music Star, etc.) and each main menu. It consists of a detailed menu according to the menu (for example, music star's detailed menu such as channel [v] live, tube music, m.net, etc.). For example, the screen when the detailed menu (for example, channel [v] live, tube music, m.net) corresponding to the main menu selected on the display of the user terminal 110 is displayed by selecting the music star). Indication is illustrated. The user may move to a desired main menu by using a key button (for example, an up and down arrow key) provided in the user terminal 110, and after selecting a main menu, a predetermined function button (for example, a menu button, etc.) is selected. By selecting), the detailed menu can be displayed on the display.

In addition, in the same manner, when the user selects a specific detailed menu and then selects a predetermined button, the detailed content list corresponding to the detailed menu (for example, thinning yo-how (0:45), etc.) is displayed in the user terminal 110. By being displayed on the display unit, the user can execute playback or storage of desired content (i.e., multimedia data) (see screen 435c in FIG. 4B).

In the process of displaying the detailed content list on the display of the user terminal 110, the MENU 'button of the function buttons is changed to the SAVE' button, and in this state, if the corresponding user plays the selected content (for example, the PLAY 'button), If the selection is selected, the content is reproduced in real time, but if the content is stored (for example, the 'SAVE' button is selected), the content data is stored in the storage of the user terminal 110.

Referring back to FIG. 4A, in step 445, the user terminal 110 checks whether the user has selected real time playback or storage (including storage and playback) for specific multimedia data.

If the real time playback or storage command for the specific multimedia data is input as a result of the check in step 445, the user terminal 110 proceeds to step 450 and transmits a multimedia data provision request to the multimedia server 120 through a communication network. However, if the real time playback or storage command for the specific multimedia data is not input as a result of the check in step 445, the user terminal 110 waits until the real time playback or storage command is input by the user in step 445.

The multimedia server 120 receives a data providing request from the user terminal 110 in step 455, proceeds to step 460 to search for multimedia data (or broadcast data, etc.) corresponding to the data providing request, and retrieves the retrieved multimedia data in a communication network. Through the transmission to the user terminal 110. Of course, when the multimedia data (or broadcast data, etc.) corresponding to the multimedia data provision request received from the user terminal 110 does not exist in the storage unit 135 of the multimedia server 120 as described above, the corresponding multimedia data Naturally, after transmitting a request for providing corresponding multimedia data to an external content server 150 that provides a, the multimedia data received from the content server 150 may be transmitted to the user terminal 110 through a communication network. The user terminal 110 receives the multimedia data (or broadcast data, etc.) from the multimedia server 120 in step 465 (see screens 465a and 465b-4b), and proceeds to step 470 to receive the multimedia received through step 465. Check whether to save the data.

While the multimedia data (or broadcast data, etc.) is received (ie, downloaded) by the user terminal 110 through step 465, a graph or number (eg, 50%, countdown) indicating the degree of reception of the multimedia data is counted. Instead of numbers, etc., the display unit of the user terminal 110 may display predetermined advertisement data (for example, a text advertisement, a video advertisement, a voice advertisement, etc.). That is, the advertisement data may be displayed on the display of the user terminal 110 during the time for downloading the content, during the time of streaming the multimedia data from the multimedia server 120, or for a predetermined time before the content is played. The predetermined advertisement data may be, for example, advertisement data already stored in the user terminal 110, advertisement data designated by a communication network operator (eg, KTF) or a content provider.

The following method may be applied to the method of storing the advertisement data on the display unit of the user terminal 110 and the method of reproducing the announcement data.

First, there may be a case in which a communication network operator transmits advertisement data (eg, video data, sound data, etc.) to a user terminal 110 applying for an advertisement compensation service using a large capacity multimedia service (MMS). In this case, the network operator may provide a free call service in exchange for the user of the user terminal 110 to receive and reproduce the advertisement data. The user terminal 110 stores the received advertisement data in a storage unit of the user terminal 110 and then displays the corresponding advertisement data on the display unit during the time when the user downloads the multimedia data from the multimedia server 120 or the like. . Of course, the corresponding advertisement data can be played for a time for which the content is buffered in memory (for example, about 5 seconds to 10 seconds) in the case of real-time broadcasting and streaming content, and stored when the user applies for the advertisement service. Any content may be automatically played just before playing. Next, the user may directly access the advertisement data storage area, select the desired advertisement data, and store the desired advertisement data in the storage unit of the user terminal 110. Even if the user does not select specific advertisement data, the communication network operator may automatically transmit the advertisement data to the user terminal 110 and store the advertisement data for the time when the user downloads the multimedia data. In this case, the corresponding advertisement data may be played in the same manner as described above.

As such, the user terminal 110 receives and stores advertisement data according to a user's selection, advertisement data designated and transmitted by a communication network operator or a content provider, and displays the stored advertisement data for a predetermined time. When a plurality of advertisement data are stored in the storage unit of the user terminal 110, it is necessary to determine which advertisement data to play, an advertisement time limit, the number of reproductions, and the like. For example, the following method may be applied to the advertisement data play order, advertisement time limit, and advertisement number setting method.

As a way of determining the playback order, for example, if you downloaded the Nike advertising data 3 days ago, downloaded the Samsung advertising data yesterday, and downloaded the KTF advertising data today, you can set the playback order to KTF, Samsung, and Nike. have. In addition, by sequentially storing the advertisement data information which is finally reproduced (for example, in case of normal reproduction, in case of random termination due to network cutting, user disconnection, battery discharge, etc.), the reproduction of the advertisement data can be made possible sequentially. . Of course, playing back ad data excludes ad data that has expired (e.g., only play that ad until a specific day) or play counts (e.g., play only the number of times requested by the advertiser). have. Naturally, the advertisement playing condition may be applied by combining various condition data (for example, advertisement time limit and playing count). The mobile terminal 110 reproduces the advertisement data through a communication network. When connected to a system, a content server, or the like, an apparatus for performing an advertisement compensation service receives advertisement reproduction information (for example, the number of advertisements played, advertisement information of which advertisements are finished) and user information from the user terminal 110. Save and notify the advertiser of the information.

Referring again to FIG. 4A, if it is necessary to store the multimedia data as a result of the check in step 470 (that is, when a storage command or a store-and-play command is input), the process proceeds to step 475 to store the multimedia data. However, if it is not necessary to store the corresponding multimedia data as a result of the check in step 470 (that is, if a real time playback command is input), the process proceeds to step 485 to play the corresponding multimedia data (see screen 485 to FIG. 4B).

As a method of checking whether to store the multimedia data through step 470, a method of checking whether a command is input from the user in steps 440 to 445 may be applied.                     

In operation 480, the user terminal 110 determines whether it is necessary to play the multimedia data stored in operation 475.

If it is necessary to play the multimedia data as a result of the check in step 480 (that is, when a store and play command is input), the process proceeds to step 485 to play the multimedia data and display it on the display unit of the user terminal 110 ( Screen 485-see FIG. 4b). However, if it is not necessary to reproduce the multimedia data (i.e., a storage command is input), the step ends. In this case, the user may perform a storage command or a store-and-play command in one step (for example, when each function button is provided). A method for determining whether to play after completion is also applicable. An example of screen display in the case of applying the latter method is shown on screen 480 of FIG. 4B.

5A is a flowchart illustrating a method of performing a helper function when playing multimedia data according to an exemplary embodiment of the present invention, and FIG. 5B is a process of performing a helper function when playing multimedia data according to an exemplary embodiment of the present invention. 5C is an exemplary diagram of a screen display showing a process of automatically executing a helper function according to another exemplary embodiment of the present invention.
