Description

[0001] The present invention relates to a content providing system and a method thereof using a mute time of a digital TV,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and a method for providing contents using a mute time of a digital TV, and more particularly, to a system and method for providing content using a mute time of a digital TV, The present invention relates to a content providing system using a mute time of a television and a method thereof.

BACKGROUND ART [0002] Recently, as digital broadcasting services are being provided, digital broadcast receiving devices such as digital TVs and digital set-top boxes are being developed to receive and display digital broadcast signals.

Generally, when watching a digital TV, every time a channel is changed, a mute time occurs in which no video signal and audio signal are displayed for about one to two seconds before moving to the next channel. This mute time is a time required from the digital set-top box to receive the digital broadcast signal and display it on the digital TV. The digital set-top box separates the video signal, the audio signal and the information data from the broadcast signal, It is the time it takes to start the next decoding.

Accordingly, the user must wait for the muting time each time the channel is changed to view the screen of the corresponding channel. When the mute time becomes long, the user may mistake the channel as a channel in which the video signal and the audio signal are not provided, or may think that the digital TV set or the digital set-top box is out of order. In order to prevent this, when the mute time is shortened, a video signal and an audio signal whose decoding has not been completed can be provided on the screen of the digital TV.

On the other hand, the effect of advertisement through TV is superior to other advertisement media, and advertisements are usually inserted before and after programs such as drama and news. Such advertisements are basically based on the advertising time, so the advertiser wants to maximize the advertisement effect for the shortest possible time. On the other hand, there are viewers who want to advertise, but there are also viewers who do not want to advertise. Therefore, it is necessary to advertise for as short a time as possible, but to display detailed advertisements only to viewers who want to advertise.

It is an object of the present invention to provide a content providing system and a method using a mute time of a digital TV for providing convenience of a user and generating profit by providing content containing information useful for a user during a mute time will be.

The object of the present invention is achieved by a digital broadcast receiving system for displaying a content selected in advance on a display panel of a digital TV at a mute time occurring when a channel is changed; And a content management server for providing the basic content to the digital broadcasting receiving system.

The object is achieved by a method comprising: detecting a channel change; Displaying the preselected basic contents on the display panel of the digital TV when the channel change is detected; And removing the content when decoding of the video signal and the audio signal of the channel to be changed is started.

In the present invention, one of the advertisement contents, the learning contents, and the local contents is displayed on the display panel during the mute time of the digital TV, thereby preventing boredom of the user and providing convenience for the user. In addition, by providing some contents to the user as a fee, the content provider can make a profit. In the case of the advertisement contents, the content management server can make a profit by charging the advertiser according to the number of times the advertisement is exposed, the time zone, and the channel.

Hereinafter, the present invention will be described in detail with reference to the drawings. In describing the specific embodiments below, various specific details have been set forth in order to explain the invention in greater detail and to assist in understanding it. However, it will be appreciated by those skilled in the art that the present invention may be understood by those skilled in the art without departing from such specific details. In some instances, it should be noted that portions of the invention that are not commonly known in the description of the invention and are not significantly related to the invention do not describe confusing reasons to explain the present invention.

In the present specification, a content is provided during a mute time in which a channel is changed in a digital TV, and the content includes advertisement contents, learning contents, local contents, and the like. When such contents are displayed, additional contents can be provided according to the user's selection. Accordingly, the content is classified into content displayed at a muting time and content provided from an external content management server or a content provider's web site. Here, the content displayed in the mute time is referred to as basic content, and further, the content provided from the content management server or the content provider's Web site is referred to as extended content.

For example, in the case of advertisement contents, the first displayed on the digital TV becomes an advertisement or a publicity screen, and actual contents are provided when a product displayed on the advertisement or the publicity screen is purchased. Here, the advertisement or publicity screen becomes the basic content, and the actual content becomes the expanded content.

In the case of learning contents, when the free contents are provided, the screen itself displayed in the mute time becomes the contents, which becomes the basic contents. On the other hand, when the paid content is provided, the advertisement or the advertisement screen for the learning content is displayed at the mute time, which becomes the basic content, and when the user selects the purchase, the actual learning content is provided and becomes the expanded content.

Although the digital broadcast receiving system of the present invention may be provided integrally with a digital TV receiving digital broadcasting apparatus, the present exemplary embodiment will exemplify a case where the digital broadcasting receiving system is composed of a digital set-top box and a digital TV 50 .

1 is a configuration diagram of a digital broadcast receiving system according to the present invention.

The digital broadcast receiving system 100 includes a digital set-top box 10 for processing a received broadcast signal, providing basic contents at a mute time and providing extended contents according to a user's selection, And a digital TV 50 for outputting the processed broadcast signal, the basic content, and the extended content.

The digital set-top box 10 processes broadcasts received from an external digital broadcast station and causes the basic content provided from the content management server 200 to be described later to be displayed at the time of mute when the channel of the user is changed, Thus providing extended content associated with the base content.

To this end, the digital set-top box 10 includes an input unit 13, a tuner unit 11, a demultiplexer 17, a communication module 15, a program storage unit 21, a contents storage unit 23, A schedule storage unit 25, a content status storage unit 27, an authentication data storage unit 29, a log data storage unit 31, and a control unit 20.

The input unit 13 processes a channel change, a volume change, a menu selection, and the like input by a user using a remote controller or a button provided in the digital broadcast receiving system 100, and provides the controller 20 with the processed result.

The tuner unit 11 tunes to the frequency of the channel selected by the user when changing the channel of the user so that the broadcast signal of the corresponding frequency can be received through the antenna not shown.

The demultiplexer 17 separates the broadcast signal received by the tuning of the tuner unit 11 into a video signal, an audio signal, and information data. Here, the information data may include an electronic program guide (EPG).

The communication module 15 supports communication with a communication network such as the Internet to enable communication with the content management server 200 as well as the Internet, which will be described later.

It is possible to communicate with the content management server 200 through the communication module 15 so that basic contents or extended contents and schedules can be received from the contents management server 200 and contents status, Authentication, log data, and the like to the content management server 200.

In addition, the communication module 15 can be connected to a web site of a content provider providing content via the Internet, thereby allowing the user to purchase the content extension directly from the web site.

The program storage unit 21 stores necessary programs in the digital set top box 10 including the web browser. When the user connects to the Internet by the operation of the communication module 15, the user can access the contents provider's web site just as the user uses the Internet through the PC by providing the web browser in the program storage unit 21. [

The content storage unit 23 stores the basic content provided from the content management server 200 and may store the purchased extended content at the user's selection. Here, the basic content and the extended content are classified and stored according to the type of the content. The types of contents include advertisement contents, learning contents, and local contents.

The advertisement content is a content for advertising a specific product, and the basic content of the advertisement content includes information about an image, a feature, a specification, a price, and the like of a specific product. When the user who views the advertisement content wants to purchase the product, if a separate content button provided on the remote controller is selected, a web site for purchasing the product is connected, and the user can purchase the product through the web site . Here, the product becomes the expanded content.

Learning contents include various contents such as English, kanji, subject learning, certification related contents, and cooking contents.

When the learning content is charged, the content storage unit 23 does not store the learning content itself, but a publicity screen for the learning content is stored as the basic content. Therefore, only when the user selects the content button of the remote controller by viewing the promotion screen of the learning content, the learning content which is the extended content can be used. When the user selects the content button, the user connects to the web site where the learning content can be purchased or is connected to the content management server 200, and the user purchases the learning content from the web site or the content management server 200 .

When the learning contents are free, the contents for learning are stored as basic contents in the contents storage unit 23, and the contents for learning are displayed at the time of the muting.

The local contents include local information corresponding to the area in which the user lives, and contents related to the area such as a publicity or advertisement screen for a restaurant, a convenience facility, and a civil defense meeting plan of the local area. When the user wants to obtain detailed information on the local contents, detailed information on the local contents is displayed on the display screen as extended contents when the contents button of the remote controller is selected.

Each of these contents is referred to as a basic content that is displayed at the time of mute when the channel of the user changes the channel of the digital TV 50. A content that is additionally provided from the content management server 200 or the web site at the request of the user is called an extended content .

On the other hand, content may be created by the user, in which case the content created by the user may be displayed at the time of the mute. For example, anniversary announcements can be registered as content. In this case, as shown in FIG. 3, a calendar is displayed on the display screen of the user, and when the user selects a specific date on the calendar, the schedule registration table 500 is displayed so that the user can enter the contents, Schedule, and so on. The anniversary announcement service content created in this manner is stored in the content storage unit 23.

The schedule storage unit 25 stores the schedule of the basic contents displayed on the screen of the user, and the schedule may be set by the content provider or may be set by the manager of the content management server 200. [ When the schedule is set by the administrator of the content management server 200, the schedule can be set for each time slot and for each channel. For example, in the case of setting by time zone, the company A advertisement may be displayed from 10:00 am to 12:00 pm, and the company B advertisement may be displayed from 12:00 pm to 2:00 pm. In addition, in the case of setting on a channel-by-channel basis, the B-company advertisement can be set to be displayed when the channel is switched from channel 11 to channel 11.

When a schedule is set from an administrator, a content provider, and a user of the content management server 200, the schedule set by the user has the highest priority.

When the schedule is managed by the content management server 200, the content management server 200 generates a schedule according to a request from a content provider or an advertiser and updates the schedule to the digital broadcast receiving system 100. At this time, the schedule may be updated every predetermined time, or may be performed every time the contents of the schedule are changed.

When the schedule is set by the user, the user inputs the type of content to be displayed at the time of mute, the content insertion time, and the like using the remote controller. At this time, the user can select the channel into which the content is to be inserted. That is, when there are 1 to 100 channels, it is possible to select the content to be inserted only when 30 to 50 channels to be mainly watched by the user are selected.

Further, the user can select one of the learning content, the advertisement content, and the local content, and when selecting the learning content, the user can select a specific content. For example, if you are interested in studying English, you can limit it to English content. And if the ad content is selected, it may be limited to specific ad content or may not be limited to the ad content. If the type of the advertisement content is not limited, the content management server 200 randomly selects the advertisement content and transmits it to the digital set-top box 1 of the user.

The content status storage unit 27 stores information on the type of basic content that the user watched during the mute time, the number of exposures of each basic content, whether or not the extended content was purchased using each basic content, and the like. The information stored in the content status storage unit 27 is provided to the content management server 200. The content management server 200 distributes the profit to the content provider using the content status provided from each digital set top box 10, .

The authentication data storage unit 29 stores authentication data, and the authentication data is used for authenticating whether or not the user is a valid user when the user intends to use the paid contents.

The log data storage unit 31 stores log data, and the log data is a history of the channel change status by the user. The log data is provided to the content management server 200. When determining the type and schedule of the basic content in the content management server 200, the type and schedule of the basic content are determined in consideration of the channel and time zone, And the like.

The control unit 20 controls i) outputting the audio signal and the video signal, ii) controlling the output of the basic content at the mute time, and iii) providing the extended content according to the user's selection.

i) Output control of audio signal and video signal

The control unit 20 controls the operation of the tuner unit 11, the demultiplexer 17, and the communication module 15 according to the selection of the user input through the input unit 13 and controls the output of the audio signal and the video signal . That is, when the user selects the channel change through the input unit 13, the control unit 20 operates the tuner unit 11 and the demultiplexer 17 to be tuned to the frequency of the selected channel, And divides the broadcast signal into a video signal, an audio signal, and information data. In addition, the separated video signal and audio signal are provided to the video processing unit 55 and the audio processing unit 51, respectively, for processing.

ii) Control of default content output during mute time

When the channel is changed, the control unit 20 fetches the basic content stored in the content storage unit 23 or receives the basic content from the content management server 200 in real time and displays the basic content on the display panel.

At this time, the control unit 20 checks whether there is a schedule of the stored basic content when the channel is changed. If the schedule exists, the control unit 20 determines whether the content is stored in the content storage unit 23 . If the content is stored in the content storage unit 23, the basic content is fetched and displayed. If the content is not stored, the content management server 200 requests the basic content.

According to an aspect of the present invention, the basic content or the extended content may be a sound. That is, the basic content and the extended content may be music, advertisement, or voice representing living information such as local information or restaurant.

According to another aspect of the present invention, the basic contents displayed for each mute time can be displayed in association with each other. For example, when the first channel is changed, the advertisement titled "The most delicious ** chicken?" Is displayed. When the second channel is changed, "Incheon ** house, phone number: 031 - *** - **** "Can be changed. In this way, by changing the channel arbitrarily, the most delicious chicken restaurant can be known. For more information, you can find out about the last displayed screen ("Incheon ** house, phone number: 031 - *** - ****") through extended contents. As described above, the basic contents sequentially provided for a specific advertisement will be referred to as sequential basic contents in the present specification.

8 is a diagram for explaining sequential basic contents according to an embodiment of the present invention.

Referring to FIG. 8, in order to advertise 'delicious XX Coke', basic contents 'taste', 'having', 'a', and 'XX cola' are sequentially displayed every time the channel is switched. As described above, by sequentially displaying the basic contents, it is possible to maximize the advertising effect by causing a curiosity to the consumer.

According to another aspect of the present invention, the default content displayed in the mute time may be anniversary announcement service content. For example, Anniversary Notification Service content may be displayed when the screen is switched from 7 days before the anniversary to the most frequently viewed channels (6, 9, 11). In addition, the Anniversary Notification Service content may include not only anniversary but also individual or family or business related schedules.

According to another aspect of the present invention, anniversary announcement service content may be included and displayed as part of other base content. For example, when the advertisement basic content is displayed at the channel mute time, it may be displayed at the bottom of the advertisement basic content.

1, a remote controller (not shown) according to an aspect of the present invention may include a button or a touch-type display unit for selecting an extended content.

In this case, as shown in FIG. 3, a calendar is displayed on the display screen of the user, and when the user selects a specific date on the calendar, the schedule registration table 500 is displayed so that the user can enter the contents, Schedule, and so on. The anniversary announcement service content created in this manner is stored in the content storage unit 23.

iii) Control of extended content output

When the user selects a content button, the control unit 20 fetches and displays the recently displayed basic content.

When the user intends to purchase the extended content associated with the basic content, the user accesses the content management server 200 providing the extended content or the web site of the content provider. Then, when the user makes a payment, the expanded content provided from the content management server 200 or the web site is displayed on the display panel 57.

The digital TV 50 includes an audio processing unit 51, a speaker 53, a video processing unit 55, and a display panel 57.

The audio processing unit 51 receives the audio signal demultiplexed by the demultiplexer 17 and processes the audio signal into a state that the audio signal can be outputted to the speaker 53.

The video processing unit 55 receives the video signal demultiplexed by the demultiplexer 17 and processes the received video signal so as to be output to the display panel 57.

FIG. 2 is a block diagram showing a relationship between a content providing system for providing contents to the digital broadcasting receiving system 100 of FIG. 1 and a digital broadcasting receiving system 100.

The digital broadcast receiving system 100 is connected to the content management server 200 via a network and transmits the basic content received from the content provider to the user's digital broadcast receiving system 100 according to a preset schedule And provides extended content associated with the basic content according to the user's selection.

The content management server 200 includes a provider management unit 210, a user management unit 220 and a server management unit 230. The content management server 200 includes a content status database 240, a content schedule database 250, 260, and the billing policy database 270.

4, the provider management unit 210 provides a schedule setting screen for setting the schedule of the basic content to the content provider connected through the network, and supplies the schedule of the provider set through the setting screen to the content schedule And stores it in the database 250.

At this time, in the schedule setting screen, the time zone and the number of times are matched according to the channel, and the charge is displayed according to the number of times. When the user selects a desired number of times from the number of times displayed in the time zone of the desired channel, the corresponding fee is charged. The channel, time zone, and number of times selected by the content provider are stored in the content schedule database 250 by the provider management unit 210.

The user management unit 220 fetches the basic content or extended content stored in the content database 260 according to the schedule set by the content schedule database 250 or the user and provides the basic content or the extended content to the digital set top box 10. At this time, when the schedule is set by the user, the digital set-top box 10 requests the basic content selected by the user when changing the channel selected by the user, and the user management unit 220 fetches the requested basic content, 10). The user management unit 220 receives the channel change information and the content viewing information of the user from the digital set-top box 10 of the user and stores the received information in the content status database 240.

The server management unit 230 changes the billing policy based on the channel change information of the user stored in the content status database 240 and the basic content viewing status. For example, when the ratings of a specific channel and a specific time zone are high, the billing of the channel and the time zone can be increased. In addition, if the user views the content and selects the content button to purchase the expanded content, the user can charge the purchase for the purchase. The changed charging policy is stored in the charging policy database 270, and is reflected on the schedule setting screen to provide charging information to the content provider.

The content status database 240 stores information on whether or not to view the basic content provided by the user's digital broadcast receiving system 100, the number of times of viewing, and whether or not to purchase extended content. In addition, the billing history of each user calculated based on the base content of the user and the usage of the expanded content, and the billing and profit details of the content provider are stored.

The content schedule database 250 stores information on the content providing channel selected by the content provider, the time zone, the number of times, and the like. The content schedule selected by the user may be stored in the content schedule database 250. In this case, however, storing the content schedule from a large number of users may be unreasonable considering the capacity of the communication traffic or the content schedule database 250 . Accordingly, when the content schedule is set by the user, the schedule is stored in the schedule storage unit 25 of the user's digital broadcast receiving system 100, and the control unit 20 causes the content management server 200 to store the basic content .

The content database 260 stores basic content and extended content produced by the content provider. The basic content and the extended content are classified and stored according to the type. If the extended content is not stored, the IP address of the web site where the extended content can be purchased is matched with the basic content and stored.

The charging policy database 270 stores a charging policy provided to the content provider and a charging policy provided to the user who intends to purchase the charged content. The billing policy provided to the content provider includes a policy for the fee to be paid by the content provider of the advertisement content and a policy for the fee that the paid content provider is required to pay for using the user's paid content. Among these charging policies, the charging policy for the fee to be paid by the content provider is provided through the above-mentioned schedule setting screen, and can be changed in accordance with the change of the user's preferred channel, preferred time zone, and preferred content. The changed charging policy is reflected in the schedule setting screen. The billing policy provided to the user is displayed when the user selects paid content.

The billing policy setting method provided to the content provider may be a billing method based on a popular channel, a billing method based on a channel on which a remote control operation is easy, or a billing method based on a specific broadcast time zone.

In the case of the charging method based on the popular channel, assuming that the game of Kim Yu-na starts at 10:00 AM on the 45th channel, when the user moves between adjacent channels 42 to 48 including the 45th channel, It is an accounting system that charges a fee.

The charging method based on the easy-to-operate channel of the remote controller is as follows: 11, 22, 33, 44, 55, 66, 77, 88, 99, 111, 222, 333 It is a charging system that charges a separate fee for channels that are easy to move by 10 units by repeatedly pressing the same number.

In general, cable broadcasting offers channels ranging from fewer to several hundreds to as many as hundreds. Therefore, it is difficult for users to memorize the names of broadcasters of such a large number of channels, and often only recognizes the number of their preferred channel or the channel of the favorite genre to be near the channel several times. For example, in the case of a user who prefers a drama, a drama channel is grouped in a 10th channel, and in the case of a user who likes a sport, the user only recognizes the fact that a sports channel is gathered in a 50th channel. In this case, it is convenient for user to move to channel 10 by moving 1 to 2 by pressing 1, rather than moving to channel 10 by pressing 1 and 0 to change to channel 10. Of course, if the user knows the channel number correctly, press the corresponding channel number.

However, if the user is in channel 53, which is the 50th channel, and wants to move to channel 10, which is the 10th channel, assuming that he does not know the correct channel number, It is better to move to channel 17 by pressing channel 11 rather than moving and then moving up to channel 17 by pressing channel up button 6 or channel 22 by pressing channel up button 5 times. Therefore, a channel in which a number is duplicated has a high frequency of use by the user, so that a separate fee is added.

On the other hand, a method of charging in a specific broadcasting time zone is a method in which a separate fee is charged to prime time zones, which are mainly watched by users.

The process of providing contents to the digital broadcasting receiving system 100 of the user in the contents providing system with such a configuration will now be described with reference to FIGS. 5 and 6. FIG.

The control unit 20 operates the tuner unit 11 and the demultiplexer 17 to tune the frequency to the corresponding channel (S610) when the user changes the channel (S600). At the same time, the control unit 20 checks the schedule storage unit 25 and checks whether the provision of the content is scheduled in the corresponding time slot when the corresponding channel is changed (S620). If it is determined that the content is scheduled, the control unit 20 determines whether the corresponding basic content is stored in the content storage unit 23 (S630). If the content is stored in the content storage unit 23, the corresponding basic content is fetched and provided to the video processing unit 55 of the digital TV 50 (S640), and the content is displayed on the display panel 57. [

On the other hand, if the provision of the content is not scheduled in the corresponding time slot in step S620, the control unit 20 causes the audio signal and the video signal to be muted (S625).

On the other hand, if the basic content is not stored in the content storage unit 23 in step S630, the control unit 20 requests basic content from the content management server 200 in step S635. Then, the basic content is received from the content management server 200 and is provided to the digital TV 50 (S645).

The control unit 20 receives a broadcast signal at a frequency tuned by the tuner unit 11 and separates the video signal, the audio signal and the information data from the demultiplexer 17 into a video signal and an audio signal, respectively, And supplied to the audio processing unit 51 to be decoded (S660). The video signal and the audio signal processed by the video processing unit 55 and the audio processing unit 51 are output through the display panel 57 and the speaker 53, respectively (S670).

The control unit 20 removes the content from the display panel 57 when a video signal and an audio signal are output.

Accordingly, as shown in FIG. 5, when the user wishes to change the channel to the channel 11 while watching the channel 5, if the user presses the channel 11, the channel is changed from the channel 5 to the channel 11 5 (B) is displayed on the display panel.

7 is a flowchart illustrating a process in which a user purchases a content in the content providing system of the present invention.

When the user clicks the content button while watching the changed channel (S700), the control unit 20 displays the most recent content displayed on the display panel 57 of the user again on the display panel 57 (S710) . When the user selects the purchase button to purchase the extended content, the control unit 20 provides the content to the user in two ways (S720).

First, when the extended content can be received from the content management server 200 (S730-Y), the control unit 20 requests the content management server 200 to purchase the extended content. Then, the content management server 200 provides the purchase screen displaying purchase information to the digital broadcast receiving system 100 (S740). When the user makes a payment, the content management server 200 stores the extended content in the content database 260 And provides it to the user's digital set-top box 10 (S750). In the digital set-top box 10, the digital subtitles 50 provide the extended contents to be output (S760).

If the extended content is received from the content provider's web site or is available for purchase (S730-N), the control unit 20 fetches and displays the web browser from the program storage unit 21, And accesses the web site through the network (S735). Then, the user purchases the extended content or product from the web site as well as the Internet (S745). If the extended content is a multimedia file, it is provided to the digital set-top box 100 by way of downloading or streaming (S755). If the extended content is a product, it is delivered to the user.

Information on the channel, time zone, number of times, and details of purchase of the content by the user in this manner is stored in the content status storage unit 27. The control unit 20 requests the content management server 200 Or provides the information stored in the content status storage unit 27 to the content management server 200 at predetermined time intervals.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims.
