[ The service manager 213 receives the service information from the SI decoder 204 and sets an audio / video PID (Packet Identifier) of the selected channel in the demultiplexer 205. The PID thus set can be used in the demultiplexing process described above. Accordingly, the demultiplexer 205 filters (PID or section) audio data, video data, and SI data using the PID.

The service discovery manager 210 provides information necessary for selecting a service provider providing the service. Upon receiving a signal regarding channel selection from the service manager 213, the service discovery manager 210 searches for the service using the information.

The service control manager 209 is responsible for selection and control of services. For example, the service control manager 209 uses IGMP or RTSP when a user selects a live broadcasting service such as an existing broadcasting system, and uses RTSP when selecting a service such as VOD Service selection and control. The RTSP protocol may provide a trick mode for real-time streaming. In addition, the service control manager 209 can initialize and manage a session through the IMS gateway 250 using an IP Multimedia Subsystem (IMS) and a Session Initiation Protocol (SIP). The protocols are one embodiment, and other protocols may be used, depending on the implementation.

The metadata manager 212 manages the metadata associated with the service and stores the metadata in the SI & metadata database 211.

The SI & meta data database 211 stores the service information decoded by the SI decoder 204, the meta data managed by the meta data manager 212, and the information necessary for selecting a service provider provided by the service discovery manager 210 do. In addition, the SI & meta data database 211 may store set-up data for the system and the like.

The SI & meta data database 211 may be implemented using a non-volatile RAM (NVRAM) or a flash memory.

Meanwhile, the IMS gateway 250 is a gateway that collects functions necessary for accessing the IMS-based IPTV service.

Referring to FIG. 7B, the user may use the VOD service while using the EPG service in the display device 700. For example, the display device 700 provides an EPG screen 710 on the original screen at the request of the user. If the user does not watch the content in the EPG, for example, if the user can not watch the previous content of the series, he / she may activate the VOD service and request the VOD content while using the current EPG service, It is possible to use the VOD service at the same time without using the EPG service or without switching the screen or taking a separate depth. Referring to FIG. 7B, an EPG screen 710 is provided within the screen of the display device 700, and the user selects certain content 720 in the EPG screen. At this time, a VOD service item 730 is provided in a predetermined area of the screen of the display device. If the user then presses the VOD service item 730 after selecting the content 720 or moves the selected content 720 to the VOD service item 730 in a drag and drop manner, the VOD service can be activated have. At this time, the activated VOD service may be provided as a different layer in the screen, such as a toast pop-up message with the EPG screen 720, for example. In the meantime, the VOD service item 730 is not provided every time a predetermined content is selected on the EPG screen 720, and may be provided only when there is a VOD server, VOD content, etc. related to the selected content . In one example, the VOD service item 730 may be provided only if free and / or paid VOD content exists for the selected content. If the VOD service item 730 is provided only when the free VOD content is present, the user can determine whether the free VOD content of the corresponding content exists from the existence of the VOD service item. In this case, the display device may provide the related message in the form of pop-up or the like, particularly in the case where the VOD service item 730 is not provided to the user in connection with the above description.

On the other hand, FIG. 7C shows a launcher screen of a display device 700 on which a Web OS platform is mounted, for example. The first screen (full screen) If a user requests a launcher, a launcher is provided on the first screen, as shown by a second screen 760. [

At this time, the launcher includes various launcher items, and includes a resent item 770, a store item, an SNS item, an external input item, and the like. Meanwhile, the launcher may include a VOD item 765 for entry, search, use, etc. of VOD service as a launcher item in connection with the present invention. Accordingly, when the user selects the VOD item 765, the display device can switch to the VOD service entry screen and use the VOD service. Alternatively, the VOD service can be used by using the recency item 770 while using another service after using the VOD service. In the case of using the recency item 770, for example, in the case of searching for a series, the VOD service can be re-entered into the VOD service without re-searching the VOD content, so that the VOD service can be continuously used There are advantages to be able to. This is because the display device loaded with the Web OS platform can support multi-tasking, and in particular, is continuously executing or maintaining in the background without terminating the VOD service previously used, so that the VOD service is newly launched The VOD service can be used more rapidly than the previous service item.

In addition, the VOD service according to the present invention can be accessed at any time while using other services or applications.

Next, when the user enters the VOD service, an embodiment of collecting the VOD service data to provide the VOD service in the display device will be described.

The VOD service data is collected, for example, from one or more VOD servers, i.e. CPs, via a connected or connectable network. However, the VOD data transmission / reception process is similar to a general data transmission / reception process between a server and a client, and a detailed description thereof will be omitted. However, when necessary, specific contents may be separately described in connection with the present invention.

Generally, CPs provide paid contents and free contents separately in providing VOD services, rather than providing all contents free of charge. The criteria that most CPs distinguish between paid content and free content are not clear, but are determined based on the date of the content's broadcast, popularity of the protagonist, or the content itself.

In particular, the present invention intends to inform the user of the point at which the charged content divided into the free content is converted into the free content, thereby improving the convenience of using the VOD service. In the present invention, in providing VOD service use convenience, that is, free content change point-in-time information, as described above, instead of accessing and providing CPs only through the CPs, And provides information such as a free conversion point of the desired content in response to the request of the user. According to a general method, when CPs are connected to provide information, it is difficult for the user to access desired content or information related thereto at a desired time point due to external circumstances such as a network situation or the like, and a separate application or the like must be executed. However, according to the present invention, the user can quickly provide information on the VOD content at any time in the process of using the display device, thereby making it easy to use the VOD content.

FIG. 8 is a view for explaining a VOD service data collection method according to an embodiment of the present invention.

The VOD service data collected in FIG. 8 includes, for example, data related to a time point at which the charged VOD content is converted into the free VOD content.

The display device accesses the VOD server, that is, the CP, for the VOD service content and collects necessary data (S804). Here, the CP includes all the servers accessible from the display device. The CP may be a preset CP set in a display device or a default CP, and the CP may be selected based on a content unit, a genre unit, or the like. On the other hand, the display device may access the CP through a URL (Uniform Resource Locator) of the CP or a CP application for a previously downloaded and launched VOD service, and collect necessary data. However, the step S804 may be performed periodically or non-periodically in the display device, for example, regardless of the VOD service request of the user. Alternatively, the step S804 may connect the CPs having the content to be free-service switched based on the service period data to be described later, and collect data. This may be done separately from the data collection period or the aperiodic period.

The display device determines whether the VOD content is free content or paid content based on the data collected in step S804 (S806). If it is determined in operation S806 that the VOD content is free content, the display device calculates a time difference between the current time and the current time of the corresponding content (S808). Then, the calculated time difference data is stored in the paid service period database (DB) 810 as paid service period data of the corresponding content, paid service period data of the genre to which the corresponding content belongs, and paid service period data of the CP providing the corresponding content (S810, S812, and S814).

As a result of step S806, if the VOD content is paid content, the display device reads at least one of the content unit, genre unit and pay service period data per CP from the pay service period database (DB) 810, The free service switching point is calculated (S816). Based on the step S816, the display device displays the free service switching point of the content (S818).

Meanwhile, in the above, the display device may perform only the step S810 for the content unit without performing all of the steps S810 to S814. In other words, at least one of steps S812 and S814 may not be performed.

With respect to the above-described time difference calculation, the display device can refer to the VOD data collected immediately before or the paid service period data that has been calculated or stored immediately before. For example, based on the immediately collected data, it can be referred to when the charged VOD content is converted into a free service based on this collected data. Meanwhile, if it is determined that the content is free content and the content is stored in the pay service period database 810, steps S808 to S814 may not be performed for the same content.

In the above description, if the predetermined content is paid content at the time of immediately preceding data collection but is converted into free content at this time of data collection, the service is switched from the paid service to the free service during the data collection time, There may be an error in the data. In such a case, it is possible to refer to the difference of the free service time calculated and displayed through steps S816 and S818 at the time of collecting the previous data, and refer to the VOD service for the corresponding content, genre, CP, and the like. And such verification data may be separately stored, for example, in the paid service period database 810. [

For example, referring to Fig. 9, t1 is the immediately preceding data collection time, and t3 is the current data collection time. And, t2 is the time when the content is changed from the actual fee to free. In other words, in the period between t1 and t2, that is, in the P1 section, the content was a paid service, and in the P2 section between the times t2 and t3, the content became a free service. At this time, P1 and P2 may be influenced by the data collection period of the display device. Therefore, P1 and P2 may not be the same, for example.

Based on the time (t3) at which the actual data is collected at the time difference calculation in steps S810 to S814, an error of P2 may occur as shown in Fig. However, the display device can not exactly know the time point t2. This is because the display devices can not know t2 accurately in real time, unless they disclose their free service switching policy at the CP. Therefore, the display device can only estimate that the content has been switched from the paid service to the free service between the time point P1 + P2 based on the time point data t1 and the time point data t3.

On the other hand, the above-mentioned error may not be a problem in constructing and providing the VOD service data according to the present invention. That is, there may be no problem depending on the difference between t1 and t3 or the difference between t2 and t3. For example, this can be determined according to the period between t1 and t3, which may not be a problem if t1 and t3, i.e., one data collection period is a short period such as seconds, minutes, and so on. However, this can be a problem if data is collected on display devices in large time units, such as months or years. With respect to the point at which the CP service is free of charge, it is common for the CP to avoid complexity and manage it on a daily basis for consistent and convenient management, such as a free transition from one week after the airing date. Therefore, if the data collection cycle is between t1 and t3 in FIG. 9, that is, the unit of data collection is not a unit of a month or a year, P2 shown in FIG. 9 is not a big deal in providing data for a VOD service to a user. However, as the period is shorter, the interval of P2 can be reduced and the accuracy can be further increased. Further, if the data is continuously accumulated in units of CP instead of one piece of content, the accuracy can be further increased, and the time point t2 can be sufficiently predicted. In addition, it is possible to infer the policy of this CP through a lot of data collection, and as the accuracy becomes high, the efficiency of the display device can be improved by adjusting the period of data collection. In addition, the display device collects more data about the free service switching point by making the period or the weight different from the other time in the time unit related to the CP policy, rather than storing and handling the data collected at every time point with equal weight .

The error can be variously stored in units of seconds, minutes, hours, days, months, years, etc. at the time of calculating the time difference at steps S810 to S814 described above. May not occur.

Meanwhile, the data collection process of FIG. 8 may be performed in units of at least one of a content unit, a genre unit, and a CP unit.

Hereinafter, a method of collecting VOD service data together with the above-described FIG. 8 or FIG. 8 will be described.

10 is a view for explaining a method of collecting VOD service data according to another embodiment of the present invention, and FIG. 11 is a view for explaining a VOD service data collecting method according to another embodiment of the present invention. FIG.

FIG. 10 is a view for further enlarging the VOD service coverage to be covered by one display device due to differences in performance, attribute, and type of each display device connectable to one service server.

A plurality of display devices can be connected to one server. Here, the server may include all servers capable of storing contents such as a service server provided by the manufacturer of the display device, various CPs, an Internet server, a cloud server, or the like and capable of data communication with the display device. However, in order to facilitate understanding of the present invention and for convenience of explanation, the server will hereinafter be described as an example of the service server. Meanwhile, the display device connected to the service server may include not only the above-described digital television but also other fixed devices such as a PC, and mobile devices such as smart phones and tablet PCs.

The display device 1010 can upload or transmit the VOD data collected by the service server 1015 itself.

The service server 1015 can crawl uploaded VOD data from each display device to provide an advanced VOD service.

The VOD service system of FIG. 10 will be described in more detail as follows.

The service server 1015 includes a control unit 1020, a crawler module 1030, a search module 1040, a processing unit 1050, databases 1060 and 1070, a search engine 1080, and a search engine 1040 for the advanced VOD service according to the present invention. ), And the like.

If there is an event from each display device, the control unit 1020 grasps the event. For example, if the event is a VOD data upload of the corresponding display device, the controller 1020 transmits the event to the crawler module 1030. [ On the other hand, the controller 1020 can request the VOD data upload to each display device when necessary for the advanced VOD service. In addition, the control unit 1020 can increase the efficiency of VOD data collection by controlling the predetermined period of each display device in advance.

The crawler module 1030 crawls the VOD data transmitted from the controller 1020. The VOD data thus crawled is processed by the processing unit 1050, and classified and stored in the database. Here, the crawler module 1030 and / or the processing unit 1050 may crawl and process the VOD data, and may include a content unit, a genre unit, a CP unit, a device unit, a device type unit, , Capacity, performance, etc., categorized according to various criteria, crawling, processing, etc. can be stored separately.

Meanwhile, the processing unit 1050 directly contacts the one or more external CPs 1090 in processing the VOD data as needed, and further adds additional VOD data to the display devices And combines the received VOD data with the received VOD data to generate and store the enhanced VOD data. Here, the external one or more CPs 1090 include CPs connected to the display device, and further include a separate CP for only the VOD service.

When the advanced VOD data is stored in the database, the service server 1015 can transmit the stored advanced VOD data to the corresponding device in response to the request of each display device to implement the intelligent VOD service. When the VOD data is requested from the display device 1010 to the control unit, the control unit transmits the VOD data request to the search module 1040 instead of the crawler module 1030. For example, the VOD data request may be a specific content, a specific genre, or a specific CP. Alternatively, the VOD data request may be a specific search term. The search module 1040 transmits a request to the search engine 1080 in response to the VOD data request. The search engine 1080 searches the databases 1060 and 1070 to read desired VOD data, (1040). The search module 1040 transmits the information to the controller 1020, and the controller 1020 transmits the information to the requested display device.

 On the other hand, when the VOD data is, for example, a broadcast program, service information (or system information) (SI) can be referred to. For example, in the DVB system, the service information includes PSI / SI information such as PAT (Program Association Table), PMT (Program Map Table), SDT (Servcie Description Table), EIT And the PTS / PMIP information, for example, PAT, PMT, Virtual Channel Table (VCT), and EIT (Event Information Table) may be included in the ATSC system. In addition, the VOD data may include service type information (SD / HD / 3D) of each content, language information (Korean, English, Spanish, ), Start time, end time, duration, rating information, genre information, video resolution information, AV type information (AV type), caption And can be separately stored based on information such as presence / absence information (caption).

Meanwhile, the service server internal controller 1020 or the crawler module 1030 may group display devices and manage and provide VOD data on a group basis.

11, an example of a cloud server system according to the present invention includes a display device stage 1110 to n, n being positive integers, a load balancer stage 1100 and a VOD host node stage 1150 to m, m Is a positive integer). Here, the load balancer stage 1100 and the VOD host node stages 1150 to m may be viewed as servers, and the display device stages 1110 to n may be viewed as clients. Also, the server may be a cloud server.

The server of the cloud server system according to the present invention uploads VOD data at predetermined time intervals from each display device terminal. Here, the predetermined time may be, for example, 10 seconds. In addition, the server can be controlled to accept uploads at least a predetermined number of times per 10 seconds. Here, the predetermined number of times may mean, for example, at least 30,000 times or more.

In addition, the server downloads the latest VOD data to the display device stages 1110 to n.

In addition, the server need not have a permanent storage medium for storing VOD data. For example, since the server temporarily stores the VOD data received from the display device but consecutively updates in consideration of the memory capacity, cost, and the like, the previous VOD data is immediately deleted and does not need to be stored permanently. Therefore, the server does not need to have a permanent storage medium. That is, when new VOD data is received, the old VOD data is deleted because it is no longer needed.

When the VOD data is uploaded from the display device, the server determines whether the previously received VOD data is present, and if the VOD data of the same version or less exists, the server may reject the VOD data upload request of the display device have. At this time, the server can transmit the next upload request time in response to the rejection to the corresponding display device. Here, the next upload request time means, for example, that the original default upload request time is 10 seconds, and that the period is incremented by 1 second for each rejection. However, if the request time exceeds the maximum of 300 seconds (5 minutes) due to subsequent refusal, it may not be increased any further. Also, the continuously increased request time can be automatically initialized if the request is allowed at a particular instant. In addition, the server can control the VOD data for other content, genre, and CP to be uploaded as a default value, ignoring the previous contents.

Also, the display device unit in the cloud server system and the VOD host node unit may not correspond one-to-one. Therefore, if control is not performed so that the transmission and reception of VOD data can be appropriately distributed to each other, problems such as server error, data error, user complaint, system error, etc. may occur due to excessive load. To this end, the server terminal may further include, for example, a load balancer 1100 for performing load balancing for each node.

The load balancer 1100 may use a server load balancing algorithm such as Round Robin, least connection, response time, hash, Minimum missies and a bandwidth based load balancing scheme may be used.

The load balancer 1100 can determine a corresponding VOD host node by using a hash method when a display device is connected through an appropriate IP address in a process of uploading / downloading VOD data.

On the other hand, in FIG. 11, each VOD host node at the server end counts the number of images to be uploaded, and can predict the popularity of the VOD data. It may be provided to the CP providing the VOD service to help the direction of the service policy of the CP and may provide the user with the popularity information to provide the user with the convenience of VOD content selection.

Next, the configuration of the VOD service GUI of the display device for providing the VOD service requested by the user based on the collected VOD service data will be described.

FIG. 12 is a diagram illustrating a VOD service entry GUI according to an embodiment of the present invention, and FIG. 13 is a diagram illustrating a VOD service entry GUI according to another embodiment of the present invention.

12 and 13 illustrate a GUI related to a VOD service entry method in a display device on which a web OS is installed, for example. 12 is similar to, for example, Fig. 7C described above.

Referring to FIG. 12, the display device 1200 on which the web OS is mounted outputs menu items, that is, a launcher only in one area of the screen, in order to minimize screen blurring that is currently being viewed, unlike a netcast TV. At this time, the launcher is output from an upper layer than the screen being viewed.

As described above, the launcher of the display device supporting the Web OS platform is provided, including the recency item 1230, the store item, and other web application items. At this time, the web application item may include VOD items 1210 and 1220 according to the present invention. That is, the VOD service according to the present invention can be provided and used in the form of a web application.

In Fig. 12, a VOD item is provided on a per-content basis such that it is accessible as a web application. Here, the first VOD item 1210 is about content called &quot; Infinite Challenge. &Quot; The first VOD item 1210 is provided with title information in the form of text such as 'Infinite Challenge - 599 times <Free>'. However, the information may be provided in the form of a pop-up message by pointing, hovering, selecting, or the like using a pointer of the user, such as infinite challenge, 599 times, and free. And the second VOD item 1220 has title information of &quot; Fly-11 times &lt; pay &gt; &quot;. Here, the second VOD item 1220 is different from the first VOD item 1210, and the billing information is not free but fee-based. Accordingly, when the user selects the second VOD item 1220, billing-related data according to the charged VOD service can be further provided. For example, the billing-related data may be various information such as a payment window for payment, a login window, information on a free service conversion time, and the like. Meanwhile, when the user selects the VOD item, which is a paid service, or performs pointing, hovering, or the like with a pointer, information on the free switching point according to the above-mentioned free conversion point calculation is provided. In addition, the information may include data enabling notification, download reservation, viewing reservation, etc. after free switching.

Fig. 13 is similar to Fig. 12 described above. However, in FIG. 13, for example, unlike FIG. 12, a VOD service item itself is provided in the form of a web application. In this case, the main screen is changed to a screen for the VOD service and includes an indicator 1310 indicating that the current screen is a screen for the VOD service, and the items of the launcher are also displayed on the VOD items 1320, 1330, Aligned.

Here, when the main screen is changed to the screen for the VOD service, any one of the GUIs of FIGS. 14 to 16 to be described later may be provided on the main screen.

Meanwhile, the configuration change of the launcher is also arranged in VOD items, and the sorting criteria may be various. For example, the VOD item may be sorted according to various criteria such as a content selected by a user as a preferred program, a content that has been most recently converted for free, an advertisement reservation, a download reservation, and a content that has been reserved for viewing.

Although not shown, a VOD item can be provided in the form of a web application in the launcher as well as a content unit, a genre unit, and a CP unit, as shown in FIG. If the content is not a content unit, the VOD service itself is provided as an item in the form of a web application. In this case, as shown in FIG. 13, the launcher is provided not only as a VOD content but also as a launcher. 14 to 16 may be configured and provided.

On the other hand, when one of the VOD items is selected in FIG. 12 or 13, any one of the GUIs of FIGS. 14 to 16 described later can be provided.

14 to 20 are diagrams showing a GUI for a VOD service configured according to the present invention.

First, as shown in FIG. 14, the display device 1400 constructs a VOD service GUI 1410 and outputs it on the screen.

The VOD service GUI 1410 may be configured in units of content. The VOD service GUI 1410 includes first to third areas 1420 to 1440. The second to third areas 1430 and 1440 are based on the content, and may be further added or deleted depending on the number of contents.

The first area 1420 outputs title information indicating the VOD service GUI, and the second area 1430 outputs information on the first VOD content and the third area 1440 outputs information on the second VOD content. do.

Although not shown, the first area 1420 may further include icon (s) corresponding to various information related to the current time, VOD service version information, VOD update information, VOD service termination, and the like.

The second region 1430 includes information on the VOD content having the title &quot; Infinite Challenge &quot; as the first VOD content. Here, the information on the VOD content includes, for example, broadcast station information broadcasting the content and CP information for VOD service. The information on the VOD content includes VOD content for at least one turn, and the 600th, 601th, and 602th turn VOD service contents are included in FIG. Here, the 600th turn represents, for example, the VOD content having the highest turnover among the VOD contents served free of charge. On the other hand, regarding the VOD content of the paid VOD service, the broadcasting time (2014.05.12, 2014.05.19.), Free conversion point (free conversion after 5 days, free conversion after 12 days) At least one of the items such as download schedule, viewing schedule, and the like may be further provided.

In the above, the free conversion point item includes data on the free conversion point calculated according to the method shown in Fig. 8 and the like, for example.

On the other hand, the remaining items except the paid preview item are related to the time when the content is converted free of charge. In other words, the notification receiving item is for notifying the user of the conversion when the content is switched from the paid service to the free VOD service. At this time, the notification may be made only once or several times according to the setting. Alternatively, the notification service may be continuously performed until the VOD service is connected. However, when the notification is made several times, it is preferable to provide the notification in a proper period in order to minimize the inconvenience of the user. Alternatively, the notification service may be performed only when a user views or accesses content related to the notification target VOD content, such as a series, a similar genre, a similar CP, or the like. In addition, a notification service may be provided when the power of the display device is turned off and on. In this case, it is possible to provide a direct access to the VOD service even in the standby state. In addition, when a specific user requests a VOD service, the VOD service may provide a notification service only when the user uses the display device through log-in, camera sensor, or recognition or authentication through the mobile device.

In the above, the download reservation item is for reserving downloading in advance when the content is switched for free. It is very cumbersome for the user to continue to check when the content is free. In addition, due to other reasons, it may not be possible to retrieve and download the content by accessing the CP or the like immediately after the free conversion. Therefore, if the content is free, and the VOD service intends to use the content for the content, that is, if the VOD content is intended to be downloaded, the VOD content is downloaded for example in the next data collection period will be. In this case, the user can access the corresponding CP at the time of using the VOD content, and can immediately view the content without having to perform a download procedure or the like. Particularly, when the user is unable to connect to the network at the time of downloading the VOD content or the download speed is very slow due to a large amount of traffic, the user may feel uncomfortable in using the VOD service. However, according to the present invention, since it is downloaded in advance from the CP in real time or in non-real time, or in various routes through one or more media in consideration of network conditions, etc., Content can be used. In addition, the display device can consider the memory capacity and the like, and can consider the power consumption or the network condition in connection with the smart grid, etc., thereby enabling quick access and economical use.

On the other hand, the viewing reservation item may also include the above-mentioned download reservation, and the user may be able to reproduce the downloaded content immediately before the predetermined time.

The third area 1440 differs from the second area 1430 only in the VOD content, and the basic content is very different. For example, the user can see that the content of the video provided by the JTBC channel was broadcasted on May 12, 2014 but could not be watched, as shown in the figure, the CJ E & M CP provides a free replay . If the user selects the free re-view item, the display device can access the corresponding CP, that is, the CJ E & M CP, access the corresponding content, download and execute 8 times content, or provide the streaming service to the user in real- . However, in the case of nine or 11 meetings, since it is still a paid VOD service, it is processed as described in the second area.

Referring to Figs. 14 and 15, Fig. 15 follows Fig. Here, the second area 1430 is provided with VOD content data called infinite challenge. Here, if the user selects the free re-view item to view 600 times of the infinite challenge, the display device connects the CP to the CP and provides the infinite challenge 600 to the user in a downloading or streaming manner, as described above. At this time, if the user selects the infinite challenge 600 times as described above, the display device also selects another VOD content 600 times before when the VOD service is the most out of VOD services provided free of charge, that is, the representative VOD content As shown in FIG. 15, a pop-up message 1510 is provided to provide another VOD content converted to a free service. At this time, the VOD content of each turn can be downloaded through the download reservation item. Though not shown, the item to watch may be replaced or included in addition to the download reservation item.

In the case of FIGS. 14 and 15, information on the time when free VOD content is immediately converted to free is provided, whereas in FIG. 16, a free conversion time point entry 1610 is generated and a free conversion Time information can be provided. In addition, the display device distinguishes the free service and the pay service through the font, font size, color, highlight, etc. of the turnaround information so as to visually recognize the free service at a time in providing the turnaround information. Also, the display device may display the remaining time until the free conversion at the free switching point item (D-3, D-5).

17 is a VOD service GUI including only the turnaround information and free re-view or paid re-view items, unlike FIGS. 14 to 16 described above. For convenience, only one VOD content is shown in FIG.

FIG. 17 shows a simple configuration of the VOD service GUI, so that the VOD content can be easily identified. Therefore, the detailed information for each rotation is configured to be accessible through, for example, a VOD content item or a replay item.

On the other hand, FIG. 17 particularly provides a free preview setting item 1710 for the paid service VOD content item. The free re-view setting item 1710 includes a sub-item 1720 such as the above-mentioned free conversion time, notification receiving, download reservation, viewing reservation, etc., The setting for the processing of the VOD service at the time of free switching can be made in advance.

On the other hand, FIG. 18 is similar to FIG. 17 in that the VOD service GUI itself is very simple, and detailed information about each VOD content turnover is provided below.

The first area 1810 provides title information, channel information, CP information, and the like of the corresponding VOD content.

In the second area 1820, VOD service content turnover information is provided. At this time, each turn information can be displayed separately by a method such as color, font, font size, size, and highlight according to whether the free service is switched or not.

The third area 1830 is provided with information such as thumbnail information, pay-watching, free switching point, receiving notification, download reservation, viewing reservation, and the like. Here, the fee-for-watching information may be provided, for example, when it is not clearly known whether the content of the corresponding turn is paid through the turnover information of the second area 1820. [ The free conversion point-in-time information may be provided only when the content of the corresponding point-in-time is paid for, for example. On the other hand, the free conversion point-in-time information may be provided together with the fee-for-watching information, for example.

The third region 1830 also provides detailed information about the VOD content of the selected turn. For example, let's say that the user has selected the VOD content for the 601 time limit. At this time, it can be known through the fee-for-watching information that the corresponding time is currently being paid service, and it is known that the service is switched to the free service after 3 days. On the other hand, the detailed information can be informed in advance of the contents of the present times which can be freely used. For example, in FIG. 18, it can be seen that the contents of the 600th and earlier times are available free of charge. Also, the CP providing the VOD content can identify the pooq. In addition, the detailed information may further include information such as performer, season information, date of broadcast, channel information, plot, and the like.

FIG. 19 shows an embodiment of a VOD service GUI configured in a display device when a VOD service is requested through the above-described FIG. 12 or 13.

Referring to FIG. 19, the VOD content can be accessed through items including a thumbnail image. Here, the VOD content is menuized, for example, in units of genres. When each item is selected, one or more VOD contents belonging to the genre of the item are provided.

Here, although VOD menu items in genre units are introduced, they may be configured in CP units or content units.

The VOD menu items may provide a preview image when the user points or selects a thumbnail image of the item. At this time, the preview image may be paid or free VOD content. On the other hand, if the VOD menu item is, for example, a genre unit, if a plurality of contents capable of VOD service exist for the genre, pointing to or selecting the thumbnail image, Thumbnail images can be sequentially provided as electronic frames. In addition, although only one thumbnail image is displayed in one VOD menu item in FIG. 19, thumbnail images can be output simultaneously as many as the number of VOD contents belonging to the menu item, or a VOD service popularity order, Only the representative thumbnail image of the VOD content having the highest priority based on the most recently used content or the like can be provided and the number of VOD contents belonging to the genre can be provided in numerical form. That is, each menu item may be a kind of folder concept. Therefore, if you set the menu item layer to receive notifications, payback view, download schedule, viewing reservation, etc., you can apply the set items collectively for the genre. However, in the case of setting only the content unit belonging to the genre, which is lower than the menu item layer, the setting items can be applied only to the content.

On the other hand, in the case of a genre unit, a CP unit, or a content unit, the display device can generate and provide an arbitrary VOD menu item according to a user's request. For example, even if the contents are provided through other genres or other CPs, when the user only wants to manage the contents he / she likes most, he / she manages them integrally through a single menu item like a folder, Selection, batch setting, management, and so on.

For example, FIG. 20 shows a VOD service menu on a per-CP basis if there is a difference from the above-described FIG. 19.

CP title information 'pooq' is provided in the first area 2010, VOD contents provided by the CP are provided in the second area 2020, and the second area 2020 is provided in the third area 2030. [ The detailed information of the VOD content selected in FIG.

Here, when the user points or accesses the CP title of the first area 2010, the display device provides a list of connected or serviceable CPs and may provide a VOD service menu for another CP according to the user's selection.

The user can access the desired content by controlling the VOD contents of the second area 2020 up, down, left, and right. Although FIG. 20 shows an example in which the VOD content provided by the CP is constituted in units of content, it may be implemented in genre units. In this case, when the user wants to view the VOD content belonging to a specific genre, the user can select the VOD content menu or access the VOD content in the vertical direction, and the VOD contents belonging to the genre can be arranged and provided. On the other hand, in the case of lateral access in the above, another genre or content is provided.

In addition, if the user selects one VOD content menu item in the second area 2020, detailed information on the selected VOD content is provided in the third area 2030. The detailed information is the same as described above. On the other hand, the selection may be made only by pointing or by a drag and drop method to the third area 2030. [

In the above description, the case where the user enters the VOD service and makes a download reservation for the VOD service through the GUI or the like, that is, the previous stage of viewing the VOD content has been mainly described. Hereinafter, the subsequent steps will be described in detail with reference to the accompanying drawings.

FIG. 21 is a view for explaining output of a notification message according to an embodiment of the present invention, FIG. 22 is a diagram for explaining an output of a notification message in an EPG service according to an embodiment of the present invention, and FIG. 23 is a diagram for explaining device selection for receiving a VOD service according to an embodiment of the present invention.

21, when the user receives a notification, a download reservation, or a viewing reservation for the current paid VOD content from the above-described contents, the display device 2100 according to the present invention stores the information about the calculated free switching point It is possible to notify that the charged VOD content is free of charge, for example. The above is the notification message provided based on the result of self determination by the display device 2100 without confirming it via the CP. As another example, the display device 2100 may connect to at least one CP having the corresponding VOD content and provide a notification message 2150 after confirming the free switching time.

Referring to FIG. 21, when a user requests to receive a notification service for a free conversion VOD content while the content is being viewed through the display device 2100, the content is changed to a free area of the screen, . At this time, in providing the notification message, the display device 2100 may provide a free re-view button to view the corresponding VOD content. Alternatively, if the CP does not provide the streaming service, the download reservation button may be provided instead of the free re-view button. In this case, when downloading of the VOD content is completed, a download completion notification message may be provided in a form similar to that shown in FIG.

Alternatively, FIG. 22 is different from FIG. 21 in that not only the current content is viewed but also an additional service, such as an EPG, displays the free converted content to provide a user's identification and use convenience.

22, if an EPG screen is provided and a user requests a free VOD service use request in advance for the content 'infinite challenge', the display device 2200 provides an EPG for a free VOD service However, as shown in the figure, the VOD notification service 2220 is added to the 'Infinite Challenge' content 2210, so that the free conversion VOD content of the previous page exists and is available. In other words, when the user uses the EPG service, it provides on the EPG that there is a free VOD service requested for the related content, genre, etc. to provide the user's convenience of identification and convenience of use. In this case, if the repetitive notification service item 2220 is selected, it is possible to select the content of the free service available time slot or the content requested by the user.

23 relates to a method for enabling a user to view through a device other than a display device, for example, based on a notification service as described above.

Referring to FIG. 23, a guide message 2310 for inquiring whether or not to watch a free service conversion fact notification message, time information, billing information, and the like is provided. At this time, the guide message 2310 may inquire whether to view the free VOD content from the corresponding display device or from another device 2360. At this time, the other device may be a peripheral device that is currently paired or connectable, or may be a device that a user has previously registered in a display device.

On the other hand, in FIG. 23, if the user wishes to view the free VOD content from another device, the download path and decoding of the free VOD content are problematic. In this case, only the download is received from the display device, Or may be transferred to the corresponding device after being downloaded or decoded by the display device. Alternatively, the VOD content can be downloaded and decoded from the beginning directly to the device.

Also, although not shown in this specification, the opposite case to that of FIG. 23 described above can also be realized, and it is also possible to simultaneously play back a plurality of devices. Alternatively, if the VOD content is switched to the free of charge in place of the notification message, the display device may access the CP, download and decode the corresponding CP, and play the corresponding free VOD content on the PIP screen. In this case, for convenience of the user, it may be possible to reproduce through the PIP screen after delivering the notification message, or to provide only the initial preview, and to reproduce at the user's option. On the other hand, the PIP screen is switchable between the main screen and the main screen. In addition, when the notification message is output to the display device or the power of the display device is turned off, the notification message may be transmitted to the previously registered device. For example, assume that a user requests a notification message for a specific VOD content via a display device at a free transition, and the corresponding VOD content is converted for free. However, if the user does not continue to use the display device for a predetermined period of time or longer, for example, the display device can notify the user of the fact that the free VOD content can be streamed or downloaded with address data , IP address, etc.). When the user accesses the address data while confirming the notification message to the device, the user can stream or download the free converted VOD data from the corresponding CP and reproduce it. In this case, the user can easily reproduce the message through the message even if the CP or other device is not connected to the other device.

24 is a flowchart illustrating a method of processing a VOD service in a display device according to an embodiment of the present invention.

A method of processing a VOD service in a display device according to an exemplary embodiment of the present invention may be performed as follows.

The display device transmits the VOD service GUI data to the external service server as described above (S2412). The transmission may be periodic or non-periodic.

The display device receives a VOD service request from the user as shown in FIG. 7 (S2414). The VOD service request may be received through at least one of a search service, an EPG service, and a launcher including a VOD service item in the form of a web application when the display device is equipped with a Web OS platform.

If the VOD service request of step S2414 is received, the display device displays the VOD service GUI on the screen (S2418). At this time, when the VOD service request of step S2414 is received, the display device transmits the advanced VOD service data to the external service server and receives the advanced VOD service data from the external service server (S2416) and reflects the advanced VOD service GUI on the output VOD service GUI . The advanced VOD service data may be generated by combining VOD service data received from each display device from the external service server and VOD service data received from one or more CPs. The output VOD service GUI includes a free VOD service item and a paid VOD service item, and the paid VOD service item includes a sub-item related to free conversion point-in-time data calculated based on free conversion point- . &Lt; / RTI &gt; In addition, the charged VOD service item in the VOD service GUI may further include sub-items for performing at least one of receiving notification, download reservation, and viewing reservation when the charged VOD service is switched to free. Meanwhile, the VOD service GUI may be configured based on at least one of a content, a genre, and a CP.

After outputting the VOD service GUI on the screen in step S2418, the display device receives the VOD service selection or setting from the user (S2420).

Thereafter, if the selected or set VOD service is the paid VOD service, the display device outputs a notification message about the free conversion of the charged VOD service on the screen when the charged VOD service is switched to free (S2422) . At this time, along with the notification message, the display device can output a message to select a device for viewing the VOD service that has been converted for free, and can select a viewing device from the user (S2424). In the above, the free conversion of the paid VOD service refers to the free conversion point-in-time reference data. If the VOD service data is collected from the CP and the VOD service is free, the time difference between the broadcasting time of the actual content and the current time And includes calculated data. On the other hand, the time difference calculation data in the free conversion point-in-time reference data can be individually stored in the content unit, the genre unit, and the CP unit.

Thereafter, the display device transmits the VOD service data from the user to the selected viewing device through step S2424 (S2426). Then, the VOD service is output through the screen (S2428).

In the meantime, when the user requests the VOD service for the specific VOD content, if the user does not restrict the CP to a specific condition, for example, a desired CP, the display device displays a free transition Based on the point-in-time data, information on the content of the CP that is the fastest free change. Alternatively, the display device may provide information about free switching points for each CP. In addition, since the VOD content is free to be switched according to the CP, and the attributes (for example, SD, HD, 2D, 3D, UHD, etc.) VOD content data may be provided.

The VOD contents processing method and the GUI for the display device disclosed in this specification can be configured and configured on the basis of the data acquired from the CP even if there is no connection with the CP etc. at the time of the user's request, And provide them. Therefore, providing a VOD content that can be serviced in a CP application or a CP site, and a GUI configuration for providing the VOD content are different from those of the present invention.

The content processing method in the display device and the display device disclosed in this specification can not be applied to the configuration and method of the embodiments described above but the embodiments can be applied to all or a part of each embodiment Some of which may be selectively combined.

Meanwhile, the operation method of the display device disclosed in this specification can be implemented as a code that can be read by a processor on a recording medium readable by a processor included in the display device. The processor-readable recording medium includes all kinds of recording devices in which data that can be read by the processor is stored. Examples of the recording medium readable by the processor include ROM (Read Only Memory), RAM (Random Access Memory), CD-ROM, magnetic tape, floppy disk, optical data storage device, And may be implemented in the form of a carrier-wave. In addition, the processor-readable recording medium may be distributed over network-connected computer systems so that code readable by the processor in a distributed fashion can be stored and executed.
