The process of displaying the play type with respect to the screen is as follows.

First, a user may select an appropriate UI provided by the main controller 10 through an input / output unit (the display panel 5, the touch sensor 6a, the keypad 6b, etc.) provided in the wireless communication terminal 100 ( When the media manager 110 is activated through the user interface, the information processing unit 111 of the media manager 110 may display a designated server, for example, an initial screen of the media server 200 shown in the drawing. The data transmission / reception unit (eg, HTTP Request) is requested by a communication protocol for a URL for connecting, for example, a URL such as “http://m.airplug.com/vod/main.html”. Request to send to 112). Receiving this request, the data transmission / reception unit 112 generates a request for a communication socket destined for the host designated by the request to the operating system 100a for a currently available communication network, and accordingly a communication socket. When this is generated, the request according to the communication protocol, for example, the HTTP request is transmitted through the communication socket to the operating system 100a. The operating system 100a is a hardware resource for a communication network associated with the communication socket to which the request is delivered (i.e. assigned a current access IP address) (if the cellular network is connected the cellular codec 1b / cellular). If the modem 1a and the Wi-Fi network are connected, the Wi-Fi codec 2b / Wi-Fi modem 2a) transmits the request according to the received communication protocol.

When the media server 200 transmits the response data, for example, main.html document according to the request by the transmitted communication protocol, the data of the document is a hardware resource (cellular codec) of the wireless communication terminal 100. (1b) / cellular modem 1a, or via the Wi-Fi codec 2b / Wi-Fi modem 2a) and provided to the operating system 100a, the operating system 100a receiving Based on the TCP connection information of the data to be identified, the communication socket associated with it is confirmed, and through the communication socket, the data transmission and reception unit 112 requested information to the data transmission and reception unit 112. Then, the data transmitting and receiving unit 112, a temporary file in the temporary storage space, for example, the memory 7 for the data received through the communication socket (this file is a file system provided by the operating system (100a) ( File information, for example, a file name, or a file pointer, is transmitted to the information processing unit 111.

When the information processing unit 111 receives the file access information in which the response data is described, the information processing unit 111 analyzes the information stored in the file. In this case, an information identifier specifically designated as being recognized / processed (the information identifier is referred to herein as a “specific identifier”), for example, certain reserved words or specific tags If the information identifier is not described in the document, the content of the document or the name of the temporary file in which the content is written is immediately transmitted to the UI processing unit 113. In one embodiment according to the present invention, the information identifier designated by the information processing unit 111 is recognized / processed, source information for a remote content file, for example, a URL or a content file for a content file. Reserved word, tag or code indicating that the URL to be obtained is listed, information about the content file (e.g., content title, size of the content file, bit per second of content, etc.) Reserved words, tags, attributes, or codes may be included.

When the UI processing unit 113 receives the contents of the document prepared according to the communication protocol from the information processing unit 111, the UI processing unit 113 transmits the contents to the operating system 100a and requests an on-screen output. The contents of the document are interpreted by the operating system 100a in accordance with the communication protocol, and the information elements described in the document are displayed on the display panel 5 according to the arrangement, format, etc. specified in the document. If the content of the received document is a menu page for a category of media content provided by the media server 200, it may be displayed 21 as shown in FIG. 2A, for example.

If the data included in the response to the request by the communication protocol transmitted previously is not created according to a specific communication protocol, the server transmitting the response data, for example, the media server 200 and the media manager. If there is an information structure according to a predetermined method between 110, the UI processing unit 113 interprets the response data according to the structure, and the screen necessary for the information elements identified according to the interpreted content By individually calling the display API to the operating system 100a, the menu screen 21 as illustrated in FIG. 2A may be directly configured.

When the user selects one menu item (information element designated to be selected) on the menu page while the specific menu page as illustrated in FIG. 2A is displayed on the screen, the UI processing unit 111 selects the selection. Is detected by the operating system 100a through the input control unit 6, and identification information, for example, a URL, associated with the selected information element is transmitted from the operating system 100a to the UI processing unit 113. do. When the UI processing unit 113 directly configures a menu page as illustrated in FIG. 2A on the screen, identification information of an information element stored by the UI processor 113 in association with the selected menu item received from the operating system 100a is stored. To be specified.

The UI processing unit 113 transmits the identification information of the information element received from the operating system 100a or its own to the information processing unit 111 as described above, and the information processing unit 111 receives the received information. A request based on a communication protocol for element identification information is created and sent to the data transmission / reception unit 112. The data transmitting / receiving unit 112 operates the request according to the received communication protocol through the corresponding communication socket if there is a communication socket previously generated for the same destination (ie, the same IP: Port address). The transmission request is made while transmitting to the system 100a. If there is no communication socket created for the same destination, a new communication socket is generated by requesting the operating system 100a, and then a transmission request is made through the created communication socket. Of course, it is also possible to create and use a new communication socket regardless of the existence of a communication socket created for the same destination.

As described above, when the request by the communication protocol for the selected menu item is transmitted to the corresponding server, for example, the media server 200 in the manner described above, and the server transmits a response to the request, The response is transmitted to the information processor 111 via the data transceiver 112. If the response data thus transmitted does not include an additional identifier, it is immediately transmitted to the UI processing unit 113 as described above, and the UI processing unit 113 has previously displayed the information described in the transmitted response. The screen contents will be updated. For example, the submenu page of the menu page illustrated in FIG. 2A is displayed on the display panel 5.

In this manner, menu pages containing menu items that can be selected for the contents provided by the media server 200 directly or indirectly (if only providing access information for the contents) are top-down. While the information is being provided on the display panel 5 on the wireless communication terminal 100 in the above manner, the response data for the selected selection page is provided with the source information for the content file which is one of the above-mentioned identification identifiers. If there is a reserved word, tag, or code for notifying the description, the information processing unit 111 performs a process of displaying a play type for the content file of the corresponding source information according to the flowchart illustrated in FIG. 3. Hereinafter, a method of displaying a play type will be described in detail with reference to the flowchart illustrated in FIG. 3.

When a response including a reserved word, a tag, or a code of a separate identifier is received from the media server 200 according to selection of a menu item on the displayed menu page (S311) (S312), the information processing unit 111 returns the response. At the same time as the UI processing unit 113 to determine the type of identification identifier included in the response. In the case of a separate identification identifier (hereinafter referred to as "source identification identifier") of a kind indicating that there is information on the source of the content file (S320), the information processing unit 111 is first connected and currently used. The data service speed of the wireless communication network is measured (S321). 4A and 4B show specific examples of the source identification identifier. 4A and 4B are examples in which URLs for video content files such as mp4, mpg, wmv, avi, and the like are indicated by the source identification identifiers 41 and 43, respectively. The source information indicated by the source identification identifier may not directly indicate the image content file. As an example of this, Fig. 4C describes link information 46 that finally obtains the file rather than the URL directly indicating the image content file. In the case of FIG. 4C, the information processing unit 111 redirects to at least one additional request using the link information 46 indicated by the source identification identifier 45 described in the response (in the case of two or more times, the response is redirected to the response). (redirection) is the response.) Finally, you get a response with a URL that points directly to the content file. As illustrated in FIG. 4C, link information for finally obtaining a content file will be described in the present specification in the meaning of the term “information about content” or “information about a content file”. .

As one method for the information processing unit 111 to measure the data service rate for the current access communication network, the information processing unit 111 may determine the content file indicated by the source identification identifier as illustrated in FIG. 4E. By using the source information, for example, a URL, a part of the head of the content is designated (411), a document 410 is created and requested to be transmitted to the data transmitting / receiving unit 112 to receive data from the server. After that, the reception speed of the data is measured to determine the current speed of the data service. If a plurality of source identification identifiers are included, the service rate for the current access communication network is measured by using one of them, for example, a section of a remote content file indicated by the first source identification identifier.

In order to measure the speed of the wireless communication network, the information processing unit 111 instructs the data transmission / reception unit 112 to measure the reception speed together with the transmission request of the designated section request document. According to this command, the data transmission / reception unit 112 confirms the data size required by the document, and then, as illustrated in FIG. 5, an event indicating that data has been received through the communication socket that requested the document is transmitted. From the time point 501 generated by the operating system 100a (t51 _k , k = 1, 2, ...) accumulated in the corresponding communication socket (the operating system 100a is received through a wireless communication resource and the communication socket After reading the data stored in the data store, the data is stored in the temporary storage space, and the accumulated data amount is accumulated and compared with the size of the required data section. If the cumulative sum of the data amount from the comparison is larger than the size of the request section, the cumulative sum of the data amount (or the size of the request section) divided by the measurement time (E * Tint in the example of FIG. 5). To obtain it and report it to the information processing unit 111 as a data receiving rate. Of course, at this time, the data of the received section may also transmit access information (eg, a name of a file temporarily generated) of the temporarily stored space.

The measurement for grasping the data service speed illustrated in FIG. 5 is merely an example, and other methods may be measured through various functions that the operating system 100a may provide, or the measurement of the actual data service may be recalled. When the operating system 100a provides the information by measuring in real time, the information may be simply checked.

The data reception rate determined as described above is that if another application running in the background execution mode in the mobile communication terminal 100 is also performing the data reception operation during the measurement operation, the data reception by the other application is performed. And the communication bandwidth of the communication network used by the media manager 110 obtained as a result of contention. In this case, the identified data reception rate is not strictly seen as the data service rate for the current wireless communication network, and the actual data service rate will be higher than the measured data reception rate. However, even if the result obtained by competing with other applications, when the media manager 110 requests the reception of one remote content file according to the user's selection after a while, if the same contention condition as the measurement is maintained, data reception Speed is likely to use the speed that was measured. Accordingly, the measured data service rate may be a data service rate that can be used separately for the current wireless communication network from the viewpoint of the media manager 110. And if there were no competing applications, then naturally the measured data rate would be the available service rate of the current wireless network. In this sense, regardless of contention of other applications, the data reception rate measured as described above is used herein as a data service rate of a wireless communication network.

After determining the data service rate for the currently connected communication network, the information processor 111 checks whether another wireless communication network is available (S330). If the currently connected communication network is a locally distributed wireless service network, for example, a Wi-Fi network, it is determined that another wireless communication network, for example, a cellular network having a wide service area, is available. If the currently connected communication network is a cellular network, the information processing unit 111 checks whether the Wi-Fi network is accessible. In order to confirm whether the Wi-Fi network is accessible, the information processing unit 111 requests and receives information on the Wi-Fi network state from the operating system 100a. The operating system 100a controls the Wi-Fi modem 2a to physically search the Wi-Fi signal band for this request, after which the Wi-Fi modem 2a is the corresponding signal band. Reads identification information of each access point (AP) and a value of a received signal strength indicator (RSSI) (r11 in FIG. 1B) provided by the AP when the valid signal is detected, and returns it to the information processor 111. If there is no access point in the returned information, the information processing unit 111 determines that the current Wi-Fi network is not accessible, and if there is an access point, determines that the Wi-Fi network is accessible. Even if there is an access point, it may be determined that the connection is not possible even when there is no connection point for receiving a signal having a predetermined predetermined strength.

If it is determined that another wireless communication network is connectable, the information processing unit 111 performs a connection to another communication network. To this end, the information processing unit 111 designates a communication network and requests a connection to the operating system 100a. When a connection to a Wi-Fi network is available, if a plurality of connection points are available in the process of checking whether the connection is available, the operating system 100a is requested to select an access point having a high signal strength and connect to the corresponding connection point. The information returned from the operating system 100a in response to the inquiry of the network connection information to the operating system 100a includes a connection IP address and a connection type (for example, a 3G mobile phone) when the access network is connected to the communication network. Communication network, Wi-Fi network) and the like, and this connection type information may be specified to the operating system 100a to specify a communication network to be connected. When there is a connection request to the communication network, the operating system 100a is assigned an access IP address from the communication network. If the operating system 100a can maintain a connection with a plurality of communication networks, even if a new access IP address is allocated, the operating system 100a does not terminate the connection with the wireless communication network to which the existing access IP address is allocated. When the operating system 100a can maintain only a connection with a single communication network, the information processing unit 111 may communicate with a desired communication network by requesting the operating system 100a for activation / deactivation of a Wi-Fi network. May be connected. When there is an active request of the Wi-Fi network, the access IP address allocated from the cellular network is terminated by the operating system 100a, and the access IP address is newly assigned from the Wi-Fi network, When there is an inactivity request, the access IP address assigned from the Wi-Fi network is terminated, and the access IP address is newly assigned from the cellular network.

When the connection IP address is allocated from the communication network according to the connection request to the other communication network, the information processing unit 111 is notified from the operating system 100a, and the information processing unit 111 is performed previously. The data service rate for the wireless communication network is determined from the time at which the reception is completed by requesting data of a part of the content file in the same manner as described above (S331). When the operating system 100a maintains the connection state to the communication network only with a single communication network, when the grasp of the data service rate for the other wireless communication network is finished, the information processing unit 111 returns to the previously used wireless communication network. By requesting the connection of the operating system (100a) so that the connection can be made.

In another embodiment according to the present invention, when it is determined that another wireless communication network is accessible, instead of directly measuring the data service speed of the wireless communication network, the measured data service rate provided from the outside may be checked and used. . For example, when the communication information providing server for providing information on the data service rate for the current access point for the wireless communication terminals is provided, the information processing unit 111 through the current wireless communication network, Information for identifying its current service area in another wireless communication network, for example, an identifier (for example, a cell identifier or an access point identifier) or a longitude coordinate information of the service area. Requesting service speed information for other communication network while transmitting to information providing server. In response to the request, the communication information providing server checks the latest speed information measured at the communication network side or reported from other terminals for the service area or point identified from the received location information, and requests the information from the requesting terminal, That is, the information processing unit 111 is provided. The cell identifier or the access point identifier can obtain the information by requesting the operating system 100a, and the longitude and latitude coordinate information is the operating system when the GPS module is provided in the wireless communication terminal 100. Can be obtained by requesting 100a. At this time, the activation of the corresponding GPS module may be additionally requested to the operating system 100a. In another embodiment according to the present invention, the information processing unit 111 has previously measured in the corresponding service area of the other wireless communication network without measuring at the time when it is determined that the other wireless communication network is accessible (for example, In this case, it is possible to check whether there is the service speed information that the other wireless communication network has measured and used to determine the play type after the wireless communication network is used, and if so, the identified information may be used.

On the other hand, the information processing unit 111, on the response page received for the selected menu item previously provided to the UI processing unit 113, information about the content file (content title, size, etc.) in addition to the source identification identifier An identification identifier (hereinafter referred to as a "detailed identification identifier") that informs the description of (a) (42 in Fig. 4A, 44 in Fig. 4B, and 47 in Fig. 4C) is further confirmed. This detailed identification identifier may be described in the same form as the source identification identifier or as an attribute factor in the source identification identifier, as illustrated in FIGS. 4A-4C. If there is a detailed separate identifier, the information indicated by the information identifier or the respective information is grasped. The information thus obtained includes the size information of the corresponding content file, and may also include information on the playback speed (or transmission speed) required for the content of the file to be played. If the size information of the corresponding content file is not determined by the detailed identification identifier, the information processing unit 111 requests the content file indicated by the corresponding source identification identifier from the description information of the file included in the response obtained. You can figure out the size. If the information by the detailed identification identifier includes the reproduction speed information on the content of the file, the information processing unit 111 uses the information as described later. Otherwise, according to the following method You will get it. If the time required for playing the content of the file is included in the information indicated by the detailed identification identifier, that is, the information processing unit 111 determines the size of the content file as the playing time. If the playback speed of the content is not divided and the playing time is not included, the metadata of the content is extracted by analyzing the data of the first section of the previously received or newly requested content file, and the metadata is extracted from the extracted metadata. By grasping and using the playback time, the playback speed of the content is obtained.

If two or more source identification identifiers are included in the response received for the selected menu item, which is provided to the UI processing unit 113 above, in addition to the playback speed for the identified content file, Determine the playback speed of the content in the same way as described in When the information on the content file by the detailed identification identifier of the corresponding content does not include the play rate information and the play time information, the play rate may be calculated as described above by receiving and interpreting the head section of the corresponding content.

After the playback speed for each content file corresponding to the source information indicated by the at least one source identification identifier included in the received response is determined, the information processing unit 111 determines the play type for each content file. If there are N source identification identifiers included in the received response, each playback speed PS _k (k = 1,2) identified according to the above-described method for the N content files corresponding to the N pieces of source information, respectively. , ..., N) previously measured data service rate of the wireless network {DSS _Cur , DSS _Oth (DSS _Oth , measured for two or more networks, for example Information can be grasped from information.)} To determine the magnitude and play type of the corresponding content file according to the magnitude. In other words, if the playback speed of the content file being compared is greater than the current service speed of the wireless network (PS _k > DSS _Cur (or DSS _Oth )), the play type is “play after download” and smaller (PS _k <DSS). _Cur (or DSS _Oth )) Decide on “Streaming”. Of course, if the playback speed of the content file is smaller than a certain allowable width (S _mg ) (PS _k <DSS _Cur (or DSS _Oth )-S _ma ) to guarantee the variability of the wireless communication state, the streaming type is “streamed”. May be determined. As used herein, the term “play after download” is not limited to the type of play in which the play is performed immediately after the download is completed, and includes only the download being performed so that the play can be performed at any time when a play is requested at any time. Used as meaning.

In another embodiment according to the present invention, instead of comparing the playback speed with the service speed, the amount of data that can be received during the playback time (that is, play time) of each content file is calculated by using the current service speed of the wireless communication network. The play type may be determined by comparing with the size of the content file. That is, if the calculated data amount is smaller than the size of the corresponding content file, the play type is determined as "streaming" when the calculated data amount is larger than "play after downloading".

In another embodiment according to the present invention, a play type may be determined by comparing the reception time required by dividing the size of each content file by the current service speed of the wireless communication network with the reproduction time of the corresponding content file. That is, if the reception time for each content file is larger than the playback time of the corresponding file, the play type is determined as "streaming" if it is smaller than "play after download".

As such, when the play type for each content file is determined for a single communication network or for each of a plurality of communication networks, the information processing unit 111 is currently displayed on the display panel 5 by the UI processing unit 113, Request to the UI processing unit 113 to output the visual information for the user to identify the determined play type for each content file on the response page received for the selected menu item S311 (S312) (S332). do.

In one embodiment according to the present invention, in order to output visual information on the play type determined for each content file, the information processing unit 111 analyzes / analyzes the received response page according to a corresponding communication protocol, After grasping the format (location, font, color, etc.) for outputting the source information by the source identification identifier on the screen, the information necessary to change the format of the location or the text of the location according to the determined play type ( For example, the UI processing unit 113 may be instructed while providing a part of the corresponding response page, such as a document according to a communication protocol in which the contents are modified or added. FIG. 4D illustrates one example of necessary information that the information processing unit 111 transmits to the UI processing unit 113 at this time. The screen displayed by the response page illustrated in FIG. background) This is an example of a document according to a communication protocol in which information (48) specified to display a color in green is inserted / modified (49). FIG. 2B thus illustrates an example of a menu page where visual information is displayed for each content on the selection menu for the content so that the user knows the type of play, for the received and displayed menu page 22. In addition, the color in which the user knows the play type for each content (assuming that the user knows the color and the play type by the pre-provided or displayed guide information about the media manager 110). Is an example of a menu page 23 added to a corresponding content as a visual information element.

In the example of FIG. 2B, the playback speed required by each of the content to which the green box 23a is added is measured for a wireless communication network (previous wireless communication network) in which the data of the response page is received. The playback speed required by each of the content to which the red box 23b has been added is lower than the service speed, and the playback speed required is higher than the measured service speed. Example of menu screen. Of course, the color-coded box is a very simple example for notifying the user by distinguishing the play type, but is not limited to this. Can be distinguished from each other. In the example of FIG. 2B, the playback time is assumed to be 70 minutes, 150 minutes, 110 minutes, and 150 minutes in the order of the list of content files, and the service rate of the current wireless communication network measured above is about 500 kbps. As shown. According to the assumption of the play time, the required playback speed of each content file is calculated to be 733kbps, 564kbps, 473kbps, and 455kbps. The playback speed of the two upper content files is higher than the service speed of the wireless communication network. The play type is marked as "streaming" because the "playback after download" and the playback speed of the two lower content files are lower than the service speed of the wireless communication network.

On the other hand, in the above-described embodiment, if another wireless communication network is available and the data service rate currently provided by the wireless communication network is also measured, the information processing unit 111 plays the case of using the other wireless communication network. In the type, the UI processing unit 113 is also displayed on the previously displayed menu page 22. FIG. 2C illustrates an example in which the play type is displayed in a background color by dividing each wireless communication network, and the left back color 24a on the displayed menu page 24 is used for the wireless communication network. Play type, the right backside color 24b represents the play type for the other wireless communication network, and at the same value as previously assumed for the example of FIG. 2b, the measured data service rate for the other wireless communication network is about 600 kbps. It is an indication based on the assumption that

When the information processing unit 111 also displays other wireless communication networks with respect to the play type, the information processing unit 111 may request the UI processing unit 113 to further configure menu items for switching the use communication network. In response to this request, the UI processing unit 113 requests that the operating system 100a insert a communication network switching item on a menu provided upon inputting a specific key on the touch sensor 6a or the keypad 6b. do. The menu item configured according to this request is a menu presented by the operating system 100a on the display panel 5 when the user selects a specific key 241 as illustrated in FIG. 2C. The screen 243 may be inserted as one selection item 243a.

If the operating system 100a can simultaneously connect and use a plurality of wireless communication networks, and other wireless communication networks are currently available, the information processing unit 111 may, in addition to the play type when using the wireless communication networks, respectively. Play types when using the plurality of wireless communication networks together are also displayed to the user. FIG. 2D is an example of the menu page displayed accordingly, and the back color for each content on the menu page 25 displayed by the UI processing unit 113 is divided into upper and lower sides, and the left side is used again for the upper side. The wireless communication network was used, the right side thereof was for another wireless communication network, and the lower end thereof was for the use of multiple communication networks. In the display example of FIG. 2D, the same values as those assumed for the example of FIG. 2C are assumed. When using both wireless communication networks, for example, a cellular network and a Wi-Fi network, the data service speed is about 1.1 Mbps. In other words, the play type of streaming is indicated as possible 25a for all the listed contents. In addition, as described with reference to FIG. 2C, the information processing unit 111 displays the play types for the use of each communication network and the simultaneous use of multiple communication networks as shown in FIG. 2D. In addition to the communication network switching item 251a, an item 251b of "Use All Communication Networks" is also inserted into the menu 251 provided by the operating system 100a when a specific key is selected.

In another embodiment according to the present invention, on the menu page displayed by the UI processing unit 113 in the form of an overlay, that is, by presenting a separate information window for changing the displayed layer (layer) to the current state of the wireless network You can also indicate the type of play accordingly. In the present embodiment, the information processing unit 111 obtains the information according to the detailed identification identifier through analysis / interpretation of the menu page delivered to the UI processing unit 113, and plays with a part thereof, for example, a part of the title. Will display the type. In the present embodiment, since the information is provided through a separate window instead of a menu page provided from an external server, the UI processing unit 113 can freely configure the information window using the information provided by the information processing unit 111. have. FIG. 6A illustrates a play type according to the current service speed of each wireless communication network through a separate overlayed window 62 for the content of the previously displayed menu page 61 according to the present embodiment. It is assumed that other wireless communication networks can be used in addition to the previously used wireless communication network, and that the operating system 100a can use a plurality of wireless communication networks at the same time, and the example of the numerical value applied to FIG. 2D is applied as it is. Yes. Of course, even in this embodiment, when the operating system 100a cannot use a plurality of communication networks at the same time, the column 62a of the “all network” is not presented in the information window 62, and other communication networks are currently available. If not, the information window 62 displays a notifier indicating that neither the column 62b of the "other network" nor the column 62a of the "total network" is presented or available.

In one embodiment according to the present invention, for a remote content file whose play type is determined to be “play after downloading”, the download time required as the measured service speed of the communication network is calculated and the screen 63a shown in FIG. 6B is displayed. It may be displayed on (S332). The download time for the item whose play type is shown as “play after download”, which is shown as an example in FIG. 6B, is the same as the numerical value (content file size, service speed of each communication network) applied to the display example of FIG. 2C or 2D. The values are calculated assuming that they are applied.

In the embodiments described so far, a menu page provided by the server receiving a request according to the communication protocol in response to receiving the menu page includes a play type determined for a content file whose source information is described in the menu page, and the like. Although it was created by the server without considering the space and format for display by the terminal at all, in other embodiments according to the present invention, a server for receiving a request according to a communication protocol, for example, the media server 200. Allows you to configure the menu page by specifying the space and format in which the play type is displayed. In other words, for the information element (for example, play type, download time, etc.) to be displayed on the menu page based on the data service speed which is determined by the terminal, the media server 200 determines the location, format, etc. of the element. An identification identifier (hereinafter referred to as "an additional identification identifier") indicating that this entry has been described is provided in the contents of the menu page along with information on the location, format, etc., and provided as a response according to the received communication protocol. Done.

When the information processing unit 111 of the media manager 110 receives the menu page configured as described above, the menu page also retrieves an additional identification identifier and additionally displays the information using the information indicated by the additional identification identifier. You will know the location and format of the information you want to do. When such information is grasped, the information processing unit 111 uses the information to determine a play type for each content file determined as described above at a designated position on the menu page displayed by the UI processing unit 113. It is requested to the UI processing unit 113 to be displayed according to. FIG. 7A illustrates an example in which a play type is displayed on a received menu page according to this embodiment, and the play types 71a, 71b, 71c and the download duration 72 shown as an example are shown in FIG. 6B. This is based on the assumptions made for the results. In the display example of FIG. 7A, the first 71a of the play type for each content is for a previously used wireless network, the second 71b is for another network, and the third 71c is for simultaneous use of both networks. will be.

In the example of the menu page illustrated in FIG. 7A, the media server 200 provides the communication speed of another communication network on the assumption that the media manager 110 receives the menu page in addition to the current communication network. In another embodiment according to the present invention, the media server 200 may provide a supplementary identification identifier in the contents of a menu page so that the media server 200 may display the play type and the like only for a single wireless communication network to which the terminal is currently connected. It may be.

As in the example of FIG. 7A, when the media server 200 provides a menu page so that the play type and the like can be displayed individually and in combination with respect to a plurality of communication networks, the operating system 100a provides data of the plurality of communication networks. If the simultaneous use of the service is not allowed, the information processing unit 111 may apply to the position of the information displayed for the entire network identified from the analysis / interpretation of the received menu page, as illustrated in FIG. 7B. The UI processor 113 requests the indicator 73 to allow the user to know that none is present. Similarly, if it is confirmed that the other wireless communication network is not currently available, the information processing unit 111 outputs an indicator 74 indicating that the information processing unit 111 is not currently applicable to the position of the information displayed for the other communication network. Be sure to

Meanwhile, the additional identifiers (sources, details, and further descriptions) described in the above embodiments are included in the identifiers for user definition defined in the request / response by the communication protocol, thereby providing the media server 200 and the media manager 110. In the meantime, the information elements corresponding to each of the above-mentioned distinct identifiers can be freely defined so that information can be delivered.

2B, 2C, and 2D, FIGS. 6A and 6B, and FIGS. 7A and 7B, which illustrate screen display examples for explaining the above-described embodiments, show content files having different contents in a received menu page. The examples are based on the assumption that there is a source-specific identifier for. However, the description of the above-described embodiments may be applied as it is when a source-specific identifier is provided for each component with respect to a content object to which components having transmission rates of different quality with respect to the same content belong. . That is, the play type may be determined and displayed for each component, and in the case of play after download, the download time may be displayed for the corresponding component. Of course, if there is information indicated by the detailed identification identifier for each component, for example, play request speed, size information, etc., the information may be displayed together.

In the above-described embodiments, when displaying the play type and the like in a form independent of the previously received menu page (for example, FIG. 6A or 6B), the information processing unit 111 may include content corresponding to the determined play type. The files may be requested while providing the necessary information to the UI processing unit 113 in order to list and display the files with good accessibility, for example, a waiting time for actual play. The specific order of listing causes the content file determined by the play type of streaming for the current wireless communication network to precede the content file determined by the download and playback. And, among the content files that are the play type of streaming, the play request rate is first listed first, and the download time is short (or the size of the content file that is small) between the content files that are the play type for download and playback. It will be listed first. FIG. 8 illustrates an example 80 of arranging 81 content files in which source information is described in a received menu page according to such an alignment criterion to display information such as a play type for each, and to display it on the screen. The display example of FIG. 8 is also based on the numerical values exemplified in the above embodiments.

In one embodiment according to the present invention, even if the play type and the like are not displayed in a form independent from the previously received menu page (for example, FIGS. 2B, 2C, 2D, or 7A, 7B), current communication Depending on the state, the content files may be listed in order of accessibility and displayed on the screen. To this end, the information processing unit 111 determines the accessibility of each content file in the received menu page based on the measured speed of the wireless communication network before transmitting the received menu page to the UI processing unit 113. Then, the information indicated by the detailed identification identifier designating the position on the page and the like is modified according to the rearrangement, and then the received menu page is delivered to the UI processing unit 113. Alternatively, the UI processing unit 113 transmits a previously received menu page to the UI processing unit 113 first, and then determines accessibility based on the measured speed of the wireless communication network and changes the display position accordingly. In addition, the order of each displayed content file may be updated and displayed according to accessibility.

In one embodiment according to the present invention, as long as there is a separate request from the user for the content files described in the received menu page, as described above, the accessibility may be listed in order from the best. The selection tool or input item for receiving the user's request is configured by the UI processing unit 113 on the screen in a proper manner at a suitable time.

In one embodiment according to the present invention, the information processing unit 111, for a content file whose play type is determined to be downloaded and played back, how much the data service speed of the wireless communication network is insufficient to change the play type by streaming. May request the UI processing unit 113 to display visual information on the previously displayed menu page or through a separate information window. Taking the specific numerical values illustrated for the above-described embodiments as an example, in the case of the current wireless communication network of about 500 kbps, for each content file requiring 733 kbps and 564 kbps playback speed determined for download and playback, 233 kbps and 64 kbps The value of, or the relative ratio to the measured service speed is output as a lack of streaming bandwidth using visual elements such as text and graphs on the screen. In the case of another wireless communication network having a speed of about 600 kbps, 133 kbps is output on the screen as an insufficient bandwidth for the 733 kbps content file determined for download and playback. Of course, it is also possible to display the size of the insufficient bandwidth by adding a certain size or ratio of the spare bandwidth to the actual shortage. The user who is aware of the insufficient bandwidth displayed in this way may change the play type of the post-download playback to streaming by moving the wireless communication terminal or changing the direction, if possible.

On the other hand, as in the above-described embodiments, after the source menu identifier is included in the received menu page to provide the user with visual information such as the play type for the corresponding content file for the first time, the information processing unit 111, When the specified specific condition is established, the adaptive display operation is performed by rechecking the current communication state and updating information such as the previously displayed play type.

Repetitive of the timer activated by the information processing unit 111 from the point in time when the UI processing unit 113 displays the play type and the like on the menu page displayed on the display panel 5 or in a separate window. The time-out may be one of the specific conditions. When the information processing unit 111 activates the timer provided by the operating system 100a, the information processing unit 111 sets and activates a period of time. In addition, the data service rate may be measured (of course, as in the above-described embodiment, other network information may be provided by using an external server provided or previously measured rate information). The play type is newly determined, and the information on the previously displayed menu page or the information displayed by a separate window is updated as the determined play type. Of course, at the time of updating at this time, the content file whose play type is determined to be played after downloading is displayed or updated as the download time according to the newly measured speed. In the information processing unit 111 repeatedly measuring the speed for the wireless communication network, as illustrated in FIG. 9A, the information processing unit 111 is next to the next section of the same content following the section 901 of the content file that has been requested for transmission. The reception speed can be measured by designating 902 and requesting transmission. Alternatively, as illustrated in FIG. 9B, by sequentially selecting (910) each of the content files in which source information is described in the menu screen displayed on the screen, requesting transmission by designating a section 911 of the contents in the corresponding order. You can also measure the reception speed of data. The interval data received for the repetitive speed measurement in this manner is classified by the corresponding contents and stored in an arbitrary space, for example, a temporary file, in the order of the intervals, so that a subsequent request to play or download the corresponding content file may be performed. At this time, the stored data may be used without requesting the data of the stored section.

When the communication network used by the wireless communication terminal 100 to use a data service is switched (for example, between 3G network and LTE network, or between 3G network and Wi-Fi network), It can be another one. Of course, this case can be applied when the operating system 100a maintains the access IP address only for a single communication network. When the information processing unit 111 is notified of the use communication network switching from the operating system 100a (the use communication network switching may also be performed by a request by the information processing unit 111, the other wireless communication terminal 100). Can be made by a variety of apps built-in or additionally installed, or at the request of a user through those apps), by specifying the duration of the content file in the manner illustrated in FIG. 9A or 9B, The reception speed is measured by requesting transmission through the network. After the reception speed measurement for the current communication network is finished, the service speed may be measured by designating the next section for the other communication network before switching and requesting the transmission (eg, as in the above-described embodiment, the external server may be It is also possible to use the speed information provided or previously measured. In this way, when the service speed of the wireless communication network is known, the play type of each content file is newly determined based on the speed, and the information displayed on the menu page previously displayed as the determined play type or the information displayed by a separate window is updated. Be sure to

The wireless communication terminal 100 may be another one of the specific conditions when a service area (eg, a cell of a cellular network, an access point of a Wi-Fi network, etc.) using a data service is changed. The information processing unit 111 detects an event generated when the operating system 100a changes the service area, or periodically checks a state variable for the service area managed by the operating system 100a to determine the service area. You can see the change. When a change in the service area occurs, the information processing unit 111 designates a section of the content file in the manner illustrated in FIG. 9A or 9B, for example, and transmits the request through a wireless communication network that is used to receive the data. It is to be measured again by the transceiver 113. When the service speed is measured again, the play type is newly determined as in the above-described embodiment so that the information displayed on the screen is updated.

The wireless communication terminal 100 receives a change in the intensity of the wireless signal received through its wireless communication resource (for example, the Wi-Fi modem 2a) by more than a certain width. It can be another one. For example, when the wireless communication network currently being used is a Wi-Fi network, the information processing unit 111 includes a source identification identifier in a received menu page, so that an initial play type is displayed on the screen for a content file associated with it. In order to be displayed on, the operating system 100a requests the information on the signal strength of the radio signal at that time (for example, RSSI) and records the reference strength, and periodically (the period at this time is Of course, it is preferable that it is shorter than the repetition period of the timer described above.) Checking the signal strength at that time, and if the changed width is more than a predetermined width (when the predetermined width is higher or lower), After replacing the signal strength with the reference strength again, as described above, the reception speed for the currently used communication network is measured again. After the measurement, the information is used to update the existing play type and the like displayed on the screen as described above.

In one embodiment according to the present invention, the data used to measure the current reception speed of the current wireless communication network or another communication network, data that is not related to the data of the content file described in the received menu page, for example, advertising, etc. You can also use the data for. For example, the data processing speed of the corresponding communication network may be measured while receiving data by designating a section for the data entity by a predetermined URL in the information processing unit 111. In this case, of course, when the measurement of the reception speed is repeated, the section following the previously received section is selected for the corresponding data object. When all of the data objects received for measurement are received in this way, the UI processing unit 113 is notified to inform the user that the data objects are prepared at an appropriate position on the screen, and when the data objects are selected, an appropriate viewer Alternatively, you can call the player to make the data object accessible so that it can be presented visually or audibly to the user.

On the other hand, on a screen in which content files (or component files of content) are listed according to any one of the above-described embodiments, any one of the remote content files (or component files) (hereinafter referred to as "content files"). The term “” (or “content”) is used as a meaning including a component file (or “content component”). When the user selects (S340), the UI processing unit 113 operates the selection. Received from the system 100a, information about the received selection item, for example, source information of the content file, is transmitted to the information processor 111. The information processing unit 111 stores the previously determined play type for the content file of the transmitted information and checks whether there is a section previously received and stored for measuring the service speed of the wireless communication network. If so, create a request according to a communication protocol requesting data after the stored interval; otherwise, create a request according to the communication protocol requesting from the beginning of the content file, and transmit and receive the request according to the written communication protocol. The transmission request is made while transmitting to the unit 112. In response to the request, the data transmitting / receiving unit 112 transmits a document according to a communication protocol requesting data of the selected content file to the operating system 100a through a communication socket created for the current wireless communication network. The request by the communication protocol is transmitted to the media server 200 through the wireless communication network. In the media server 200 providing menu pages for selecting a content file, the actual content file may not be stored, but may be stored in another server. In this case, the request by the communication protocol is naturally transmitted to the other server. Is sent.

In response to a request by the communication protocol, the media server 200 (or the other server) transmits data of the requested content file as a response so that the wireless communication terminal 100 receives the signal (S631). Data is transmitted to the data transmitting and receiving unit 112 through the communication socket by the operating system (100a). The data transmitting and receiving unit 112 transmits the received data to the information processing unit 111. At this time, the information processing unit 111 if there is data of the corresponding content file previously received and stored for the received data. After that it is stored.

If the operating system 100a can simultaneously access and use a plurality of communication networks, the user may designate the use of the plurality of networks through an appropriate menu item or input item provided by the UI processing unit 113 so that one content file may be used. When receiving the request, the UI processing unit 113 also informs that the use of a plurality of networks is specified when transferring information on the selected content file to the information processing unit 111. When the use of a plurality of networks is specified, the information processing unit 111 divides the data of the corresponding content file into sections of arbitrary size, and distributes each section to a plurality of wireless communication networks to request transmission. To this end, the information processing unit 111, as illustrated in FIG. 10, determines the corresponding section 1010 _k at the time of requesting transmission of the data 1010 of the selected content file and specifies the section 1011a. Wireless communication network, e.g., cellular network 1021 and Wi-Fi, that can make a request according to the communication protocol, for example, HTTP Request (1011 _k ), and make available the request according to the written communication protocol. Appropriate distribution to network 1022 (1030), for example, alternately selects and transmits each communication network. In order for the request by the communication protocol requesting the interval to be transmitted through the designated communication network, the information processing unit 111 also specifies a communication network to transmit when transmitting the request according to the communication protocol to the data transmission and reception unit 112, Accordingly, the data transmission / reception unit 112 designates a communication network, requests the operating system 100a to generate a communication socket, and requests the operating system 100a to request the communication protocol through the generated communication socket. By sending to the server, it sends a request to the server. Of course, if there is a communication socket previously created for the same destination (ie, host) as the corresponding communication network, the communication socket may be used.

The information processing unit 111 determines the size of the section N _k in determining the section for the selected content, and receives the data of the section (that is, requests by the communication protocol for requesting the section). According to the above-described method for the wireless communication network to be transmitted, it may be adaptively determined according to the speed of the data service measured by the data transceiver 112. For example, if the data service speed is fast, the size of the interval can be increased accordingly.

On the other hand, while the data of the content section is being received using a single communication network or a plurality of communication networks in accordance with the above-described process, the data transmitting and receiving unit 112 is the data of the communication network in the manner described above The service rate is measured and notified to the information processor 111. The information processing unit 111 uses the data service rate measured in real time as described above, and when the menu page on which the content file is currently listed by the UI processing unit 113 is displayed on the screen, each of the listed contents is displayed. The play type and the like for the file may be newly determined at the notified data service speed and updated accordingly.

When the data of the selected content starts to be received using a single communication network or a plurality of communication networks in accordance with the above-described process (in the latter case, the process of arranging the received sections in the order of the requested sections is involved). The information processing unit 111 confirms the play type of the corresponding content previously stored. If the checked play type is a download and play back, the content data is completely received without play and then configured as a complete file.

If the checked play type is streaming, the information processing unit 111 is connected to a mime type included in the description information of the file, which is received before the data file is received. A process or application, for example the media player 10, is started. To this end, the information processing unit 111 generates an intent object 1100, which is an information structure, as illustrated in FIG. 11, and mime type and target information in the object 1100. For example, the package name (Package_ID) for the media player 10, the source information (Content_URL) of the selected content file, for example, a URL may be described, and the intent object 1100 may be described as a mediator ( argument) to call an API function provided by the operating system 100a. The generated Intent object 1100 is configured in accordance with an information format defined by the operating system 100a for exchanging information / commands between processes. Of course, when the user designates the media player 10 as a designated player in the usage environment setting for the media manager 110 or when the user has previously designated the information processing unit 111, the information processing unit 111. ) May list only the package name of the designated player in the Intent object 1100. If there is no predetermined player, the information processor 111 may not write a package name in the intent object 1100. In addition, when the description information is not received for the content file or the mime type is not known from the received description information, the call of the other application is made while the source information (Content_URL) of the selected content file is described. 100a) may be requested. If the mime type is described in the received intent object 1100, the operating system 100a uses the application connected to the mime type, and if the mime type is not described, the extension name of the content file identified from the source information described. An application connected to, for example, the media player 10 is started. Of course, if there are a large number of connected applications, the selected application is started through a selection window designated as default or presented to the user. At this time, the source information of the content file described in the intent object 1100 is also transmitted to the media player 10 which is activated as a call parameter.

When the media player 10 is activated, it occupies the display screen of the display panel 5 (ie, is executed in the front execution mode) and according to the communication protocol by the source information received as a call parameter. A request is made to create a communication socket while creating a request and providing it to the operating system 100a, and sends the request according to the created communication protocol back to the server, for example, the media server 200, through the generated communication socket. The media player 10 receives the data of the content file, which is a response previously received by the media manager 110 through the generated communication socket. The media player 10 determines a decoding scheme by encoding information included in the data of the received content file, and then partially or completely decodes the content data according to the determined decoding scheme. In case of partial decoding, the decoder 8 is also set to the determined decoding method. The partial decoding may be extraction of media packets, for example, block unit, picture unit, or Group of Pictures (GoP) unit. In the case of the partial decoding as described above, the decoded media packets are applied to the decoder 8 to request decoding so that the video and audio data thereof are output. The video data decoded as described above is applied to the display driver 4 to be output as a video signal on a play screen designated and occupied by the media player 10 (S342).

In another embodiment according to the present invention, the media player 10 does not request transmission of data of the selected content file from the beginning based on the received source information. It is also possible to request transmission from the subsequent data using information on the previously received data transmitted by the information processing unit 111. To this end, the information processing unit 111, as illustrated in FIG. 11, the information 1101 (for example, the size of the received data 1101a) of the data received and stored before the call of the media player 10. ) And the name of the stored file 1101b) are described in the Intent object configured as described above, and transmitted to the media player 10 through the operating system 100a. As such, when the media manager 110 provides the information 1101 about previously received data, the media player 10 uses the size information 1101a in the information 1101 and then adjusts the size. Based on the received source information (Content_URL), a request by the communication protocol for requesting data is created and transmitted to the corresponding server. For the data received, the file name (in the information 1101 of the received data) Subsequent to the previously received data in the file designated by 1101b), the content data stored in the file is read from the beginning and decoded so as to be output as the corresponding video and audio (S342).

Although the above embodiments are related to the case where the process of decoding the data of the received content file and outputting the image and / or the audio is a separate application completely separate from the media manager 110, another embodiment according to the present invention is provided. In one embodiment, as illustrated in FIG. 12, the media manager 110 ′ includes a decoding processor 114 for decoding and outputting content data as an internal component or a process. In this embodiment, the format of the information exchanged by the information processor 111 to exchange content data to the decoding processor 114 may be freely defined and used mutually. For example, internal variables or local function arguments and / or return values. In the present embodiment, unlike in the above-described embodiment, after the decoding processing unit 114 starts to decode, the information processing unit 111 continues to end the data of the content file until the end of the data file or the user's interruption request. It is received and provided to the decoding processing unit 114.

On the other hand, the media player 10 or the decoding processing unit 114 starts to play by decoding the content data when the received and stored data has a predetermined amount or more, and whether or not the predetermined amount is possible to play the stored data. Judging from time. For example, the predetermined amount of time determined from the difference between the PTS time (or DTS time) described in the header of the head PES packet of the corresponding content data and the PTS time (or DTS time) of the last PES packet currently received and stored; For example, if the time corresponds to 3 or 5 seconds, the above-described play operation is started.

Meanwhile, in a state in which a menu page including visual information about a play type of each content file and the like is output on the screen (S332), when a request of the "previous page" is received from the user (S350), the UI processing unit 113 This information is transmitted to the information processing unit 111, the information processing unit 111 is a request by the communication protocol to obtain a response page that was delivered to the UI processing unit 113 immediately before the currently displayed menu page, for example By sending the HTTP request back to the server, receiving the response page and transmitting the response page to the UI processing unit 113, the processing operation for the currently displayed menu page ends. Of course, when the source identification identifier is also included in the menu page which is received again according to the "previous page" request, the determination of the play type as described above with respect to the content file indicated by the corresponding source identification identifier and The screen display operation is performed.

In the above-described embodiments, the measurement of the data service rate for the wireless communication network performed by the data transmitting and receiving unit 112, and the measured or for each content file in the received response performed by the information processing unit 111 The functions for determining the play type (including update) according to the identified speed and calculating the download time (S321 and S330 to S332 of FIG. 3 and related operations) of the data transmission / receiving unit 112 are performed. And not included in the information processing unit 111, the operations are performed in accordance with a document in which the execution document that is provided externally at the time of the request, such as a web document, for example, the execution statement specifying a work order such as a script May be Of course, the function of displaying the play type determined (or updated) by the execution document may be included as a unique function of the information processor 111. FIG. 13 illustrates a configuration of the media manager 110 "according to the present embodiment, wherein the information processing unit 111" at this time is configured to communicate with the wireless communication terminal 100 through the provided communication means. A request according to the communication protocol is transmitted to the server, for example, the web server 210 through the data transmission / reception unit 112 ″, and is received together or separately in response to the request, for example, the reception 1301 of the web page ( 1302) The state tracking unit 110a in the form of an execution document to be executed is divided into the data transmission and reception unit 112 " and each execution object as illustrated in FIG. 13, and the state tracking unit 110a. ) Performs the above-described measurement of the data service speed and the determination of the play type (including the update decision) according to the measured speed.
