Description

A system and a method for intercepting bad contents and offering alternative contents during TV broadcast using network}

The present invention relates to a method and system for blocking harmful content and providing alternative content during a TV broadcast using a network. More particularly, the present invention relates to a content providing system of a digital or analog TV. The present invention relates to a method and a system for blocking harmful content and providing alternative content in a TV broadcast using a network to automatically block and output alternative content.

Due to the development of TV technology and broadcasting media, existing analog TVs are being transformed into various types of services such as digital TVs, IPTVs, and DMBs. Basically, the TV content providing service is one-way, that is, when a broadcast provider or a broadcasting station unilaterally transmits broadcast content, the user receives it and outputs it to a TV display.

The main problem in this reality is that general viewers of TV must accept contents transmitted from the broadcast provider. Among the contents provided by the broadcast provider, there are a large amount of harmful contents such as contents classified by program grades according to the degree of harmfulness, advertisement contents that are broadcast by anti-mandatory to an unspecified number, and the like. Adults can block this by stopping watching TV when harmful content is being broadcast.However, children who do not fully develop their judgment skills are difficult to determine whether the content is harmful, even if it is considered harmful content. Immature ability makes it difficult to stop watching TV on their own. As described above, it is well known that when children are repeatedly exposed to harmful contents, there is a high risk of adverse effects on the judgment ability, the way of thinking, and the values of the children.

For example, a big problem of Korean advertising is loan (advertisement) advertising, which is broadcast without any discrimination from general advertising, and is broadcast with a considerable amount of time. However, as these loan advertisements are delivered to an unspecified number of viewers without any filtering, as the immature viewers such as children and minors are exposed to the loan advertisements, the bonds are naturally and routinely It is likely to be accepted. Accordingly, such viewers are more likely to grow into adults with distorted economic ideas, such as using bonds without any objection.

In the past, the advertising market itself or the influence of the advertising itself was not so large that the advertising in the past was mostly made for actual buyers. In the past, the focus was on the direct impact of advertising, namely on the increase in visible sales of the product being advertised, so that the target of the advertisement is the actual buyer and the amount of information that is used to make decisions about what is beneficial to them. It was made for adults who can exercise judgment.

However, recent advertisements are increasingly aimed not only to increase short-term sales of a single product, but also to increase long-term sales of all products sold by the company by injecting their image into an unspecified number. ought. As a result, most of the recent advertisements are aimed at children as well as adults, which means that companies are trying to make their products and services 'cradle to grave'. Children are unaware of their position as consumers in the market, and these advertisements are adversely affected in many ways (physical and mental health, education, creativity, values).

Children are particularly negatively affected because they are unable to exercise their own judgment on these ads. For example, preschoolers may not be able to distinguish between TV commercials and regular programs, and if they are larger, they may be able to distinguish between the two, but young children who are not yet concrete think that they tend to believe all the 15-second commercials. There is research. On average, children under eight do not really understand that advertising is designed to persuade them. So kids may think that what they say is not real, but they often have a strong opinion that a brand is 'best'. It's not based on your own experience, but on what you see in commercials like TV. Ads appeal to emotions, not intelligence, and therefore have a much greater impact on children than adults.

Violent or sensational videos, as well as advertising, have a significant psychological impact on children. Of course, ratings are given for each program in consideration of violence or sensibility, so that the ratings are displayed when they are aired. However, this is only an unmeasurement based on the premise that there will be guidance and guidance of children in the viewing of children. There is no measure to prevent content from being viewed by children.

As described above, children will accept the contents of the image in front of their eyes without any judgment of value, and if they are continuously exposed to violent or sensational images, it is likely that they will show violent behavior or have distorted sex values. have.

It is well known that exposure to harmful content such as advertisements, violent and sensational programs is likely to cause mental imbalances in children, and therefore, watching and watching children's TV requires guidance and guidance from their parents.

However, in the case of the conventional TV system, as described above, only the content that is transmitted unilaterally is output according to the schedule provided by the broadcast provider, and there is no way to prevent such harmful content in the absence of a guardian.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to automatically block harmful content and at the same time to broadcast the alternative content, the external synchronization server and stream The present invention provides a method and system for replacing harmful content in a TV broadcast using a service.

At this time, when the external server 9 determines the harmful content using the broadcast tag, the external server 9 uses the broadcast tag information for distinguishing the broadcast and commercial broadcasts provided by the broadcast provider to display advertisement data corresponding to the commercial tag. It is determined that the content is harmful, and comprises a module for updating and storing the broadcast tag identifier provided by the broadcast provider.

Alternatively, when the external server 9 determines whether the content is harmful by using a timetable, the external server 9 uses the broadcast timetable information provided by the broadcast provider to delete the harmful content in advance by the user's selection and the advertisement which is the broadcast in the time domain that is not on the broadcast timetable. And determining a broadcast in the time domain corresponding to the broadcast classified as the content as harmful content, and updating and storing broadcast timetable information provided by the broadcast provider.

Alternatively, when the external server 9 determines whether there is harmful content by using image processing, the broadcast data currently compared with the broadcast data currently broadcast using a comparison pattern made through image processing with respect to broadcast data selected by a user's selection If the pattern is judged to be matched or similar, the broadcast is judged to be harmful content, and a hash table or a comparison table of the comparison pattern for the broadcast data selected by the user is configured and stored, or a pre-produced comparison pattern is transmitted from the service provider. It is characterized by comprising a module for receiving and storing.

In addition, the external server 9 is composed only of a TV synchronization server, or a TV synchronization server and a content providing server.

According to the present invention, by effectively blocking harmful content, a viewer who needs a viewing guidance such as a child or a minor can prevent an exposed content from being viewed indiscriminately without a guardian. In particular, the present invention is applicable to all TV systems, such as analog TV, digital TV, IPTV, DMP, etc., and thus has the effect of having high compatibility.

In particular, according to the present invention, there is an effect that does not harm the continuity of the broadcast by broadcasting sound substitute content instead of harmful content, and also has an effect that allows the viewer to have a sound effect as the alternative content is repeatedly watched.

Hereinafter, a method and a system for blocking harmful content and providing a substitute content stream during TV broadcasting using an external synchronization server according to the present invention having the above configuration will be described in detail with reference to the accompanying drawings.

There may be various methods for blocking specific content of a broadcast. Generally, in order to block specific content, a method of analyzing the content, obtaining a specific pattern from the analyzed data, and then blocking the same or similar pattern in the analyzed content may be used. Depending on the method, there may be a method of blocking.

1 illustrates an output system of a general digital TV. In the general digital TV system as shown, first, the received broadcast data is classified by the channel decoder 1, and the image data is separated by the T / S decoder 2 from the broadcast data corresponding to the channel selected by the user. do. Thereafter, the image data is converted into a format according to the size of the display 5 by the format converter 3, and the image data and other data such as an image, text, etc. are combined by the OSGM 4 to finally display the display 5. )

At this time, in the present invention, as shown in FIG. 2, a module for blocking the output content and replacing it with another content according to the content of the broadcast before the broadcast data is output to the display 5 is further included.

The embodiment shown in FIG. 2 will be described in more detail. After the received broadcast data is classified by the channel decoder 1 and the image data is separated by the T / S decoder 2 from the broadcast data corresponding to the channel selected by the user, the image data is converted into a format converter 3. Up to the portion where the format is converted in accordance with the size of the display 5 by the same as in the prior art. In addition, the system of the present invention includes an external server 9 which determines whether broadcast data transmitted from a broadcast provider is harmful content, and transmits a control signal and a video signal, the channel decoder 1, and the format converter ( 3) connected to the external server 9 and receiving control signals of the external server 9 for broadcast data received from the channel decoder 1 and the format converter 3, and the broadcast data is harmful. If the broadcast data is determined to be harmful content by the processor 6 and the processor 6 which perform an operation corresponding to the control signal determined according to whether or not it is recognized, the broadcast data is stored in the content storage device 8. It further comprises a switch 7 for replacing with the replacement content.

The processor 6 and the content storage device 8 are connected to the external server 9 through a network, and the external server 9 transmits a control signal and a video path. Done. The processor 6 receives the control signal and performs an operation according thereto, and the content storage device 8 receives the video signal and collects replacement content. The processor 6 causes the switch 7 to output the replacement content when the external server 9 determines that the corresponding broadcast data is harmful content.

There are three ways for the external server to determine which broadcast data is harmful content. The first is to use broadcast tag, the second is to use timetable, and the third is to use image processing. Each method is described in more detail below.

A first method, that is, a method using a broadcast tag will be described.

In systems such as digital TV, there are specific tags that distinguish between broadcast and broadcast, and commercial and commercial. Therefore, the external server 9 can distinguish between the present broadcast and the commercial broadcast using these broadcast tags. Through this division, the broadcast data corresponding to the broadcast tag is transmitted to the display 5 as it is, and the broadcast data corresponding to the advertisement broadcast tag is not applied to the display 5 without removing the corresponding area. will be. This method can block advertisement content very easily, but there may be a difference in blocking capability depending on whether the broadcast provider, that is, the broadcasting station transmitting unit correctly processes the tag separator.

In the case of using the first method, it is preferable that the external server 9 includes a module for updating tag delimiters according to changes in transmission processing, so as to use them to distinguish tags. In this case, the external server 9 stores the broadcast tag information and update information on the broadcast tag delimiter in the content storage device 8 or the internal memory of the TV using the module, and loads the updated information.

The first method can effectively block commercials, but it is difficult to block violent / selective programs during the broadcast.

A second method, that is, a method using a timetable will be described.

All public broadcasting stations and cable broadcasting stations also manage their own timetables, and such timetable information is provided on their homepages. The timetable has time information on what program is running at what time, and all of the parts not included in the broadcast timetable may be referred to as advertisement areas. Therefore, by using the timetable information, it is possible to block all advertisement areas or to block specific harmful contents in the timetable.

In the case of using the second method, the external server 9 preferably includes a module for updating broadcast timetable information from a provider such as a homepage of a broadcast provider from time to time. The external server 9 stores the timetable information such as the content storage device 8 or the internal memory of the TV using the module and loads the timetable information for use in the determination process.

The function of scheduling a specific program using a timetable is also widely used in general digital TV. In the digital TV, the contents of the program selected by the viewer are stored in the HDD inside the digital TV according to the timetable. It provides the ability to see it later. According to the present invention, the basic function of the digital TV may be used to output the alternative content that the viewer has previously selected and stored in the harmful content broadcast time domain.

A third method, that is, a method using image processing will be described.

Recent image processing technology is developing rapidly, and the time required to analyze an image of the size of video data for TV broadcasting is greatly shortened, and thus, image processing techniques can be used to determine harmful contents.

As described above, in the case of digital TV, broadcasts are generally divided into tags. Therefore, after distinguishing the beginning of each broadcasting data using such a tag, image processing is performed for 1 ~ 2 seconds from the starting position of each broadcasting data, and whether the corresponding broadcasting data is advertisement, what kind of advertisement, or violent / selective program. Determine the cognition.

In general, video data output from a digital TV depends on the degree of image quality, but most of them are composed of at least 30 ~ 60 frames. A frame in which the features are distinguished is selected from the frames configured as described above, and by using the pre-made pattern input by the user as the comparison pattern, it is possible to determine which broadcast is the corresponding broadcast. The comparison pattern used herein may be separately provided as content. If the currently broadcast video is determined to be identical or similar to the comparison pattern, other content designated by the viewer is output on the screen until the next broadcast data is output for the corresponding broadcast part (usually between 15 and 40 seconds for the commercial). By doing so, harmful content can be blocked.

This method of using image processing is particularly advantageous for blocking advertising. Since the production of the advertisement itself is very costly and also costs a lot for maintaining a certain period of time for one advertisement, it is difficult to change the advertisement for one product frequently. You will have more than three to four months of maintenance time. Therefore, even if a new advertisement is produced, a comparison pattern can be produced quickly at the beginning of the commercial, and after that, the advertisement can be effectively blocked (until a new advertisement is produced).

In order to perform image processing, a receiving device of a TV needs to receive a broadcast input and analyze it. In general, such a receiver is installed in a TV, and in the case of a digital TV, it may be converted into an MPEG form for storage or display. Broadcast data may be obtained by passing a content blocking filter before storing or displaying the received data.

In general, a data transmission method in which only a portion having a large change according to the screen state is selectively converted into data and transmitted is widely used. In other words, the first screen is a technique that transmits the data of the part where the person or a certain movement is transmitted if most of the data is transmitted as it is and the background data does not change. do. Especially in the case of commercials, the corners and background parts of the screen do not change significantly, and the movement of people in the center and the output of specific characters are mainly used. For such broadcast data, a comparison pattern can be easily extracted. Using the corner part, which is the core of the advertisement, whether the block is present or not can be applied through RGB comparison. For example, in recent years, in the case of corporate bond advertisements, the screen is quickly changed and screen processing is performed at a specific location. The hash data or comparison table for a specific screen is mainly configured to detect broadcast data corresponding thereto. To block it. Of course, it is possible to use the method of comparing the entire data, but in this case, the amount of data to be processed is increased and the system load is excessively high, which may cause broadcast interruption or other problems.

That is, a method of using image processing is to construct a hash table or a comparison table of comparison patterns with respect to the screens of predetermined harmful content, and block the detection if the currently broadcast video has a matching or similar pattern. . The external server 9 preferably includes a module for constructing or updating a hash table or a comparison table of the comparison pattern.

As described above, the method for blocking the harmful content and outputting the replacement content may be performed by the processor 6 as well. However, when the processor 6 directly performs such an operation, the load increases, and thus, a high performance processor must be used to increase the price of the TV unit. At this time, the external server 9 performs this determination process, and the processor 6 only accepts a control signal received from the external server 9 to perform a simple process, thereby providing The load can be greatly reduced.

That is, in the present invention, it is determined whether the harmful content using the three methods described above, the determination is not made in the viewer TV stage, but made in an external server connected to the viewer TV stage, the viewer TV stage is transmitted from the external server only It is only necessary to perform the operation according to the control signal. Therefore, the load on the viewer TV stage, that is, the processor 6 can be greatly reduced, and more services can be configured through the connected network.

3 illustrates the configuration of such an external server and the connection with the viewer TV. The external server 9, i.e., the TV synchronization server in Fig. 3, monitors the contents of all channels for each digital TV (channel monitoring is performed by one of the above-mentioned broadcast tag use, timetable use, and image processing use). Each content is divided and the divided information is transmitted to each TV as a synchronization signal as a control signal. This synchronization signal is content-division content according to the channel selected by each viewer's TV. The processor 6 of each viewer TV can use this synchronization signal to know whether the current broadcast data is harmful content, and when the determination result is harmful content, the media of the peripheral device (VTR player, CD player, DVD player, etc.) is recognized. It replaces the broadcasting area by taking the real-time video stream information from the network or through the network.

In FIG. 3, the external server 9 is composed of only a TV synchronization server. However, at this time, the external server 9 may be embodied in an integrated form of a TV synchronization server and a content providing server, or may be independent. It can be made in various forms such as implemented in a combined form as. When the content providing server is provided independently of the TV synchronization server, of course, the content providing server may be connected through at least one network per one TV synchronization server, wherein the TV synchronization server is configured to provide the content providing servers. It can also be managed. Of course, without being limited to the description of the configuration example of the external server as described above, the external server 9 may be designed in any form without departing from the spirit of the present invention. The external server 9 does not need to output the same substitute content to all the TVs, and it is preferable to output different substitute content according to each TV. In addition, when the area where the TVs controlled by the external server 9 are distributed is wide, the content broadcasted according to the area may vary (specifically, local broadcasting or local advertising), and whether harmful content is broadcast for each TV. Whether or not, that is, whether to output the replacement content may be different. Therefore, it is obvious that the external server 9 should be formed so as to distinguish each TV separately. The classification of each TV may use a unique identification code such as an IP address of a network network to which the TV is connected or a product serial number embedded in the TV itself, and the implementation thereof may be implemented without departing from the spirit of the present invention. It can be freely designed according to the designer or user convenience.

As shown in FIG. 3, when the external server 9 is composed only of a TV synchronization server, the processor 6 receives only a control signal transmitted from the external server 9 to receive the content storage device 8. The alternative content stored in advance in the can be sent to the switch 7 to be output. Alternatively, when the external server 9 includes a TV synchronization server and a content providing server, the processor 6 provides a control signal from the TV synchronization server of the external server 9 to provide the content of the external server 9. The video signal received from the server may be sent to the switch 7 to output the video signal received from the content providing server as substitute content.

The main advantage of this method is that there is no need to have a module for monitoring and controlling all contents of the broadcast on the TV side, and only a part of changing the content using externally inspected information through a network connection is required. As a result, it is possible to minimize the load on the viewer TV and provide more various contents and functions through the network. In particular, according to this method, even if the user's TV is an analog TV, only a module configured as described above can be configured as a digital TV.

4 is a flowchart illustrating a method of blocking harmful content and outputting replacement content using the system of the present invention as described above. That is, the flowchart shown in FIG. 4 shows the operation by the processor 6 and the external server 9 shown in FIG. More specifically, in FIG. 4, the portion indicated as [external server] is an operation performed by the external server 9 and the remaining part by the processor 6.

First, the processor 6 receives broadcast data from the channel decoder 1 and the format converter 3 (S101). At this time, when the processor 6 receives a channel selection command by a user input (S102), the processor 6 sets a channel according to the channel selection command (S103).

Thereafter, the external server 9 analyzes the broadcast data (S104) to determine whether the broadcast data is harmful content. As described above, the method for determining whether the external server 9 is harmful content may be selected from a method using a broadcast tag, a method using a timetable, and a method using image processing.

As such, when the analysis is performed by the external server 9, and it is determined that the broadcast data is not harmful content (S105-No), the external server 9 controls the control signal according to the determination result by the processor 6. Send it. The processor 6 receives the control signal and transmits the broadcast data to the switch 7 (S106). Also, the processor 6 performs analysis by the external server 9 so that the broadcast data is harmful content. If it is determined (S105-Yes), the processor 6 delivers the replacement content to the switch (7) (S107b).

At this time, when the external server 9 consists only of a TV synchronization server, the external server 9 transmits only a control signal to the processor 6, and the processor 6 sends the switch 7 to the switch 7. The substitute content stored in advance in the content storage device 8 is delivered (S107b). Alternatively, when the external server 9 includes a TV synchronization server and a content providing server, after the video signal transmitted by the content providing server of the external server 9 is received by the content storage device 8 (S107a) ), The processor 6 receives a control signal transmitted by the TV synchronization server of the external server 9 according to the determination and accordingly comprises a video signal transmitted by the content providing server to the switch 7. The alternative content is delivered (S107b).

As shown in FIG. 2, the switch 7 is connected to the OSGM 4 and the display 5, and the data output from the switch 7 is finally output to the display 5 (S108). ).

Hereinafter, a method of using alternative content will be described in more detail.

As described above, when the commercial and the specific broadcast content are determined to be harmful content, the corresponding broadcast area is not transmitted to the display. This makes the broadcast appear to be broken, in which case the user may feel uncomfortable or heterogeneous. Therefore, the present invention blocks harmful content and simultaneously displays specific content selected by the user in the blocked broadcast area.

Such alternative content can be a collection of video clips such as a music video, a specific pattern such as a screen output when listening to music only on a Windows media player, a video related to a work of art or cultural asset, or an educational video. May be divided into general replacement content or user replacement content. General alternative content refers to alternative content that can be provided regardless of the user, such as educational videos, music video clips, or specific patterns. User alternative content is a video promoting a place where the TV is installed (e.g., a TV installed in a restaurant) It refers to an alternative content that is customized according to a user's needs, such as a restaurant promotion video or a TV installed in a accommodation resting place of a tourist destination.

Hereinafter, a method of providing general substitute content will be described in more detail.

If the general alternative content is educational content such as an introductory video of a cultural heritage or a work of art, a description of a particular history or general content of science, a formula used in mathematics, or a simple English educational video, The effects of advertising can be used to educate children and can play an important role in attracting children's interests. This provides a way to turn the bad parts of advertising into educational advantages and expect new effects in education.

Such a method of providing alternative content is provided by using a method of receiving pre-produced content, and downloading the content in advance by being connected to a content providing server in real time or at a time of outputting broadcast data instead of harmful content. There is a way to be provided. The following describes each in more detail.

The first method is a method of inputting and using general alternative content, such as preconfigured educational content, in the content storage device 8. That is, in the case of educational content, the sold form is in the form of a media or file such as VHS, CD, DVD, HD-DVD, Blu-ray, etc., which is purchased and inputted into the content storage device 8 to replace general content. It can be used as. Alternatively, the content storage device 8 may be an external device implemented as a VHS player, a CD player, a DVD player, an HD-DVD player, a Blu-ray player, or the like. Even if the content is not directly stored in the terminal, the content may be provided simply by inserting the media (CD, DVD, etc.) containing the content, and thus may be referred to as a 'content storage device' in a comprehensive sense. However, this method has a disadvantage in that it is necessary to repeatedly watch the purchased content.

The second method is a method in which the content storage device 8 is provided with content in a manner that the content storage device 8 is network-connected to a content providing server to download in advance at the time of outputting broadcast data in real time or not harmful content. For example, in the case of education content, when the content is provided in the form of a file to be downloaded and used from the homepage, the education content may be connected to the corresponding education content homepage at the time when the replacement content is to be output and may be output in real time. Alternatively, content in the form of a file or broadcast data (not harmful content) of another channel may be downloaded in advance at the time of outputting broadcast data that is not harmful content, and then output at a time when substitute content should be output. . In this case, depending on the choice of education method, the benefits can be derived in a more effective way than in regular education. In other words, interest-based education can be changed in the middle and repetitive education can be selected, but new education contents can always be applied. In these cases, more effective educational content can be used by billing by time of day or viewer's status, rather than using specific media or content.

The general alternative content is most preferably made up of such educational content, and this educational content will be described in more detail.

The composition of the educational content is based on the composition of one time of the general advertising area. Sometimes it can be composed of connected educational content, but in general, a long advertising method may not help children's concentration.

An example of English education content is as follows. At present, general English education consists of at least 40 minutes of education, which can make the education bored. And it is not easy to replace TV broadcasting for such a long time. However, if the conversation-oriented educational content is repeated broadcast using content that can convey meaning within 30 seconds in everyday English, the situation and conversation techniques can be left in the viewer's memory. It is also possible to create a more efficient educational situation by inducing interest and curiosity about the next situation through the production by dividing the specific situation. (This is the method currently used a lot in advertising.) For a piece of education, it is enough to replace one advertisement, but you can also organize the educational content into a series of stories that continue to follow a specific education scenario.

Examples of cultural and historical educational content include: It can be used for educational purposes as a fragmentary screen on historical facts or cultural parts. For example, National Treasure No. 1 is Sungnyemun, when it was made, and one advertisement time is enough to inform the historical facts about it. And when it comes to the work of art, whoever made it, what information it has, general common sense, and even certain formulas, can apply.

As such, there may be content that can be implemented in a fragmentary education, but it may be necessary to watch for a long time. In this case, various areas of the advertisement may be used as one long time educational content, or the story may be composed of one piece of content like an advertisement having a story.

In addition, the contents of the educational contents may be automatically applied to the contents of the contents according to the user's selection or through managing the age, gender, and desired educational directions of the registered children.

As a child grows, intelligence needs to change to see and feel and to learn, and the same educational content is applied to children's education each time. Accordingly, by continuously changing the educational content suitable for the child using the age or characteristics of the child, it can lead to continuous interest. If the education target is a newborn child, the educational content is applied to the newborn child, and when the child gets older, the appropriate content is automatically applied. If you go to pre-kindergarten, you can either select the educational content according to the pre-kindergarten education or automatically apply. (In this part, information about personality and educational management of children can be applied to educational contents using a specific management server.) If you go to elementary school, apply the educational content suitable for elementary school students, and if you go to middle school, the middle school curriculum Appropriate educational content for And if you are a high school student preparing for the SAT, you can apply a lot of educational content to help you with the SAT. (For example, if you use English word memorization contents, you can display English word-oriented contents that appear frequently in the SAT test instead of advertisements. If there is a book you want to read, you can display information by linking the information related to e-books. Infants may use fruit names / characters, animal names / characters, learn Korean, learn English basics, or other content that can be created by viewer parents.

As above, the automatic or selective educational contents according to the children's growth can be used to draw the interest of the children and to derive the effective educational method for the children.

Hereinafter, a method of providing substitute user content will be described in more detail.

As described above, the alternative content may be configured not only with general alternative content including education content, but also with advertisements having their own characteristics desired by the user.

Most restaurants, for example, have large TVs. In this case, the broadcast content viewed on the TV may be output as it is, but for the case of another advertisement area, the menu of the restaurant itself may be configured as a live image or a specific screen. Advertisement of a restaurant's menu can increase the interest in other menus to customers who are dining in the restaurant, leading to additional orders from other menus, or creating a situation where current guests can drop by the restaurant. This increases the chances of ordering another menu. It also plays a role in attracting customers to its own restaurant by printing advertisements outside the restaurant about passing pedestrians around the restaurant.

In this way, not only the user's own promotion, but also promotion of facilities and malls around the user. As an example, when a TV with a hairdresser explains and advertises a nearby restaurant or nail art store on TV, it greatly increases the curiosity of the people. You can increase your chances of finding. Through their own unique advertisements and advertisements of other facilities around them, it is possible to greatly increase sales by inducing consumer response and curiosity.

Of course, such alternative user content may also be stored in an external server (content providing server), the alternative content is stored in the TV, such as restaurants, beauty salons, such as connected to this to download and output the alternative content content providing method, such as Technically the same method as the general alternative content (that is, a method of receiving and using pre-produced content, a network connection to the content providing server in real time or in a manner that is downloaded in advance to output broadcast data that is not harmful content) To receive the content).

The replacement content is stored in the content storage device 8 connected to the TV and then output when necessary. As described above, the content storage device 8 may be read / writeable in the form of HDD or VHS / CD /. Or in the form of a player capable of reading and outputting media (which stores content) such as DVD / HD-DVD / Blu-ray, or the content storage device 8 may be connected to an external content providing server that stores content. It is connected via a network to download and output the content in real time or in advance from the content providing server.

Herein, the content providing method when the content storage device 8 is connected to an external content providing server will be described in more detail below. The content providing server stores contents such as a video, music, etc., which may be formed in a stream format and transmitted through a network to be output in real time, or output after being transmitted and stored. In addition, the content storage device 8 is connected to an external server 9 via a network as shown in FIG. 2, wherein the external server 9 is configured as a TV synchronization server and a content providing server. The content storage device 8 is connected to a content providing server to receive replacement content. At this time, when the content storage device 8 requests to download the content by accessing the content providing server, the content providing server grants the content type, the download amount, the transmission speed, and the content storage device to download. Charging can be performed based on established authority.

In the performing of charging for the alternative content, in the alternative content providing step illustrated in FIG. 4, after the broadcast data is determined to be harmful content by the external server 9 (S105-Yes), the content providing server performs the content. Preferably, before the step S107a of transmitting the video signal to the storage device 8 is performed. In more detail, the charging step is as follows.

First, the content storage device 8 is identified by the content providing server, so that the content providing server can recognize information of which content storage device is to download replacement content. As the identification method, as described above, the TV's IP address or a unique identification code owned by the TV can be used. For example, the user A has a pre-stored information indicating that the TV has an IP address of 123.456.789.012. When the content storage device 8 of a TV accesses the content server and requests a download, the TV can look up the IP address of the TV to identify that the TV is the user A. Here, the case where the IP address is used as an identification criterion has been described as an example, but of course, other identification criteria may be used.

Next, the replacement content to be downloaded to the content storage device 8 by the content providing server is selected. For example, User A wants to use only educational content as an alternative content at the time of contract, and another User B wants to use music video content and user B's restaurant promotional video content as alternative content. At this time, if the content providing server recognizes that the user A's TV attempts to download the replacement content as in the above example, the content providing server may transmit to the user A's TV among various contents stored therein. The content is selected only from the educational content. Of course, selecting one of a plurality of educational contents may be freely selected according to the type or convenience of the contents, such as randomly selecting or selecting a specific sequence of contents according to a date. If the user B's TV requests to download the replacement content, the replacement content is selected from the music video content and the user B's restaurant promotion video content in a similar manner. As described above, the content providing server of the present invention may provide replacement content in a customized manner according to a condition previously requested by the user.

Next, after charging is performed for the identified content storage device 8 using the selected replacement content by the content providing server, the selected replacement content is downloaded by the content providing server. In this case, it is preferable that the content providing server performs charging differentially according to charging criteria such as an alternative content type, an alternative content file size, a transmission speed, and an authority granted to the content storage device 8. For example, you can charge educational contents and make music video contents available for free download.In detail, educational contents can be made according to the degree of difficulty of the educational contents contained in the educational contents or the completeness of the contents. Is free of charge, middle and high school students at a regular price, and adults and professionals at a special price (differential charging depending on the type of alternative content). Alternatively, short content of 10 minutes or less such as music videos, movie trailer clips, etc. can be downloaded free of charge, and billing of content longer than 30 minutes, such as video lectures, can be performed (depending on the size of the replacement content file). Differential charging). Alternatively, more charges can be made to users with faster transmission speeds by using transmission priorities to users who pay higher service rates during simultaneous access (differential charging according to transmission speeds). Or, since each user's TV is identified individually, User A has contracted to be authorized to use educational content, so when a download request of User A's content storage device comes in, user A charges at the price A, and User B himself. Since the user is authorized to use the restaurant's promotional image, the user may perform billing according to the user, such as billing at the price of B when a user B's request for downloading the content storage device is received (granting to the content storage device). Differential charging according to the rights granted).

In this way, by charging the download of the alternative content, it is possible to pay appropriate costs to the producers of the alternative content (ie educational content producers, promotional material production company, etc.), it is possible to have a high quality alternative content. . Of course, there is an advantage in that the user can pay a small service fee and view high quality alternative contents.

The present invention is not limited to the above-described embodiments, and the scope of application of the present invention is not limited to those of ordinary skill in the art to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Of course, various modifications can be made.
