The present invention relates to a method for automatically generating and displaying a preference list of a TV broadcast program that shows a program of a currently viewable broadcast on a TV screen based on a priority calculated in real time based on a viewer rating or an individual preference when watching a TV. will be.

Broadcast information or an electronic program guide (EPG) provided through a broadcast reception or a network in an existing TV or STB / PVR provides broadcast program information in various forms.

These electronic program guides are very inconvenient and difficult to select and watch the program of their choice based on the hourly broadcasting information screen in the age of 100 to 10,000 multi-channel era. .

The most representative method of the electronic program guide may be provided in two-dimensional table form for each channel / time band, or may show only the channel information currently broadcast in one-dimensional order form.

In addition, the EPG information may be edited and displayed in the form of a preferred channel EPG. All of them show channels determined based on channels in a certain order, and this order can be changed according to individual preferences.

However, there is no technology, method, or service that changes the channel order in real time according to the program.

On the Internet, real-time search query rankings on portal sites such as Google and Naver are used to measure interest areas and rank them by complex algorithms through settings such as importance and relevance. In other words, Web 2.0-based web sites make it easy to find popular or interesting sites through search terms, and personalization is being promoted in the future.

As with the Internet, 10-20 prioritized program information can be calculated in real time on TV, so that it can be a very useful service for viewers if they can see the program ranking on the screen with a single remote control.

An object of the present invention for solving the above problems, prior to the personal preference or popular program ranking to viewers to see what interesting programs are currently provided in which channel in the age of 100 to 10,000 or more multi-channel when watching TV It is to be provided in real time on the screen through the ranking list.

In addition, the present invention, when the viewer presses the "preferred program" or "preferred channel" hot key set on the remote control while watching a broadcast, a window is displayed on the TV screen, the channel information is provided by the higher order is shown preferred We want to provide a method for creating and displaying lists automatically.

In addition, according to the present invention, if a desired program is selected according to a priority list, channel information on which the program is broadcasted is transmitted to a service server in real time, and automatically generates a preference list of a TV broadcast program whose priority is changed again based on the above operation. And a display method.

As described above, a service server receives broadcast signals and program information from the broadcast provider 30, stores these signals and information in each database, and generates preference channel priority information through the signals and information. 20); A relay device which receives the preferred channel priority information and the broadcast signal from the service server 20 and transmits it to the TV 11; It is achieved by a system for automatically generating and displaying a preference list of a TV broadcast program, comprising a TV 11 for outputting broadcast information received from the relay device and preference channel priority information on a screen.

In the present invention, it is preferable that the TV 11 further includes a remote controller 12 having a preference channel designation key 13 so that the preference channel priority information is displayed.

In the present invention, it is preferable that the relay device is either the STB 10 or the PVR 10 '.

In addition, in the present invention, the viewer information DB 23 preferably generates a viewer genetic code in which the programs watched by the viewer are listed and recorded for each category in the designated viewing time.

In addition, the present invention, it is preferable that the viewer genetic code is displayed in a chronological order arranged by a letter or color symbolizing each category to display a viewing pattern.

In another aspect, the present invention, it is preferable to provide a channel genetic code for calculating the similarity with the viewer genetic code to provide an additional weight for each program through the correspondence of each channel.

In addition, the present invention, the PVR (10 ') has a recording function, it is preferable to include the recorded program in the priority calculation to reflect the preference and weight.

In addition, the present invention, the repeater is an IPTV or VOD-type TV having a partial recording function of the front part of the program introduced in order to quickly change the channel or streaming, the selection of a limited number of partial recording program through the genetic code information Or, it is preferably used in the list of recommended programs.

In addition, the present invention, the step of transmitting the broadcast signal and program information from the broadcast provider 30 to the service server 20; Generating preferred channel priority information through the broadcast signal and program information transmitted to the service server (20); The preferred channel priority information is preferably provided on the screen of the TV 11 via the repeater from the service server 20 by the operation of the remote control 12 of the TV 11.

In addition, the preferred channel priority information is personalized by combining the history information for viewing the program through the quantized weight set by each program or the channel weight calculated by the real-time viewing status information for each channel of the relay device. Preferably, the information is calculated by weighting the pattern.

In addition, in the present invention, it is preferable that elemental importance of the program is displayed as a vector by genre or category, and a viewer viewing pattern is also represented by a weight vector having the same form to calculate individual preferences of the program internally of the two vectors.

In another aspect, the present invention, it is preferable to provide a channel genetic code for calculating the similarity with the viewer genetic code to provide an additional weight for each program through the correspondence of each channel.

Hereinafter, a method of automatically generating and displaying a preference list of a TV broadcast program of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall configuration diagram of a method for automatically generating and displaying a preference list of a TV broadcast program of the present invention, FIG. 2 is a priority list provided on a TV screen according to an embodiment of the present invention, and FIG. Genetic code of a method for automatically generating and displaying a preference list of a TV broadcasting program.

As shown in the figure, the system for automatically generating and displaying a preference list of a TV broadcast program according to the present invention includes a STB 10 or a PVR 10 ', a TV 11, a remote controller 12, a service server 20, and a broadcast provider. It consists of 30.

In the embodiment of the present invention, since the broadcast communication in both directions is possible, the proposal is applicable to a TV or STB (Set-Top-Box) or PVR (Personal Video Recorder) equipped with a network function. It can also be ranked in the preference programs.

As shown in FIG. 1, when the viewer presses the favorite channel designation key 13 through the remote controller 12 while watching TV through the TV 11 (or STB / PVR), the preferred channel window appears on the TV screen. Here, the priority list of the currently viewable broadcast program is listed together with information such as the title of the program, so that when the desired channel is selected using the remote controller, the desired program can be immediately watched. The size, position, and display method of the preferred channel window may be implemented in various ways according to the viewer's setting.

That is, as shown in the example of FIG. 2, the screen may be arranged in one side of the screen, or may be provided as a single-line subtitle slide at the bottom of the screen.

The preferred channel priority information is provided from the service server [7] through the communication network 1 connected to the TV terminal. At this time, since the provided information is text information in Bianry or XML format, there is almost no communication load.

The service server 20 receives broadcast information from the broadcast provider 30 and the STB 10 or the PVR 10 'and calculates the data with an appropriate data value, and calculates the STB 10 or the PVR 10'. The broadcast signal is transmitted to the TV 11 through.

The service server 20 calculates a preference function of each channel in the viewing time zone from the broadcasting information DB 21, the program additional information DB 22, and the viewer information DB 23 in order to determine the preference channel priority in real time. The ranking is determined accordingly. The function value of the preference function can be calculated in the form of the dot product of the importance vector of the program and the viewing pattern vector of the viewer. The components of the vector are subdivided into categories of the program.

That is, the broadcast information DB 21 is EPG information for each channel time slot received in real time from each broadcast PP (program provider) or SO (service provider) or EPG information agency. Therefore, this broadcast information DB 21 provides information on which program each channel is broadcasting at a given time.

The program additional information DB 22 is a detailed additional information DB for program information obtained from the broadcast information DB 21, and the importance of each category of the program is determined in real time based mainly on an official rating of the program.

At this time, when the information on the program is not provided or the basis is insufficient as an official viewership, the real-time viewing for each channel of the STB 10 or the PVR 10 'that is linked to the service server 20 and provides the viewing information in real time. Automatically calculated values based on state information may be used.

In this case, in order to build a more accurate DB, the service provider may be constructed in consideration of all the past viewer ratings, expected viewer ratings, information on the host or performer, publicity situation, social importance, etc. collected through a number of research channels.

The viewer information DB 23 is personalization information that is constructed based on a viewing history sent from the STB 10 or the PVR 10 'of the viewer's home, and occurs when an event (power on, off, channel change, etc.) of the TV terminal occurs. Each time, the STB 10 or the PVR 10 'transmits the signal to the service server, and the service server analyzes it through an algorithm for analyzing the same to generate the viewing pattern data.

In the present invention, as an example of dividing the viewing pattern into categories, that is, movie, drama, entertainment, sports, information, and education ( This study proposes the concept of 'Viewer's Genetic Code', which is divided into seven categories such as Learning, Kids, etc., and displayed according to time zones.

For example, an array of 48 categories from 0:00 to 24:00 in 30-minute increments for 24 hours a day. As shown in FIG. 3, it is preferable to arrange them in English capital letters of each category or a specific color code corresponding thereto.

For example, if the viewer's genetic code is 10 in KNDESSNMMO, 30 minutes for infants, 30 minutes for news, 30 minutes for drama, 30 minutes for entertainment, 1 hour for sports, 30 minutes for news, 1 hour for movies and 30 minutes without watching The minute (in English) is broadcast in sequence.

In terms of color, it is desirable to visually display the gene sequence by expressing each category in red, orange, yellow, green, blue, indigo, violet, and white for not watching.

More specifically, the drama can be divided into history, melodies, and sitcoms, and more specifically, can be divided into preferred broadcasts, preferred time zones and preferred casts.

The algorithm configuration sets quantified weights for each pattern for each program and combines the information about the history of viewing the program to calculate the weight of the personalized pattern. This is averaged over a given time period to provide a comprehensive pattern.

Based on the viewer information DB, the channel preference can be personalized and calculated in real time. The personalized real-time channel information priorities are sent to individual TV terminals in XML format.

Finally, other information DB and service server allows viewers to select specific programs or viewing patterns through wired and wireless Internet.

The STB 10 and the PVR 10 'are general relays that receive broadcast information and are transmitted to the TV 11, and the TV 11 is a broadcast received from the STB 10 or the PVR 10'. It displays the information and displays the favorite channel priority information on the screen by operating the remote control.

The remote controller 12 is a general apparatus using wireless communication to transmit command information to the TV 11, and is provided with a preferred channel designation key 13, and prioritizes the preferred channel to the TV 11 by pressing the designation key. Ranking information will appear.

Therefore, when a viewer presses a "preferred program" or "preferred channel" hot key set on the remote control while watching a broadcast, the service window 8 (exemplary service name 'ACORANK' 8 ') is shown in FIG. In the upper right corner of the display, the channel information (channel name or program title) is provided for each higher rank.

Selecting the desired program (8 ") (for example, 1st Grey's Anatomy, 2nd Piece, 3rd Desperate House Wives) will take you directly to the channel where the program is broadcast.

This priority is changed in real time, and it is desirable to provide 10 to 20 pieces at a time so that the left side scroll bar 8 " or the arrow keys can be searched.

In addition, as shown in FIG. 2, the sponsor channel or program 9 appears at the top of the ranking window irrespective of the ranking (for example, the ESPN channel at the top of FIG. 2).

The sponsored channel is an advertising channel that is designated and shown for the profit of the service, and it is desirable to allow the consumer to voluntarily select it so as to be visually and positionally distinguished from the preferred channel.

At this time, the method of determining the real-time priority includes the real-time broadcasting program DB, the DB of the viewer ratings, the predicted popularity, the propensity of viewers, and the personalized preference information DB built on the viewing information broadcast from the TV terminal. Let the rank of be determined. For this, communication infrastructure between TV and service server is essential.

Of course, it may be determined within the TV terminal based on the real-time broadcasting information received from the TV 11, additional information for each program, and viewing type information. However, in order to provide more commercially available ranking information, a large DB is provided by an external server. It is a more realistic way to calculate the ranking result in real time and send it to the TV terminal in real time.

In other words, if you press the preference program designation key while watching TV, 10 to 20 preference programs are displayed on the screen so that the user can go directly to the desired program.

This real-time program personal preference or popularity ranking is provided from a networked service server, which is collected in real time from the real-time broadcasting information DB 21, the program additional information DB 22, and the viewer information DB 23. The real-time ranking is calculated based on the information.

The ranking information thus obtained is received in real time from a TV terminal (TV or STB or PVR), and when a viewer wants to open a window on the screen and send it directly to the desired channel or program through this window. Also, according to the viewer's setting, the ranking information can be displayed on the TV screen in various ways.

For example, when the new top program rank is changed, the rank window is automatically displayed on the screen, or the lower notice so that viewers can watch it without missing it.

Here, one example of the method of calculating the preference rank is as follows.

For n channels, if the preference function of the i-th channel is fi, the preference function value in the j-th time interval tj is fi (tj). Therefore, the priority of the channel in the tj interval is determined in order of the preference function value. At this time, the function value is defined as the dot product of the importance vector Pk of the program k provided in the tj time interval in the i th channel and the viewing pattern weight vector Vm of the viewer m.

If the program importance is divided into n genre or category elements and set as the importance P1, P2, ■, and Pn for each category based on the audience rating, cast, publicity, etc., the importance vector Pk has an nth order vector having the element value. do. For example, when three categories are used (information type, drama type, and education type), if the program k is "MBC news desk", the vector Pk = (6, 0, 0) is set. In other words, since the viewer rating is high, the importance is high, but only the information type category component is included.

The viewing pattern weight vector is calculated based on the viewing history data of the viewer, and is continuously upgraded in the form of placing more emphasis on the recent history as the viewing history is accumulated.

If the viewer m who is watching the drama rather than the news is m, the viewing pattern weight vector Vm may be in the form of (0.1, 0.7, 0.2), where the viewer function's preference function value is the inner product of the two vectors. The value is (6,0,0) (0.1,0.7,0.2) = 0.6.

If program q is a drama "opening gossip" with half the viewer rating than the news desk, at the same time, the importance vector Pq is set to (0,3,0). But the preference function for viewer m is (0,3,0) (0.1,0.7,0.2) = 2.1, which will be higher than the news desk.

However, in most cases, each program is not provided with subdivided weights for each program. Instead, the information is designated as one category.

Therefore, in this case, the broadcasting pattern of the program according to the time slots by channel is the same as that of the viewer's genetic code, such as Movie, Drama, Entertainment, Sports, and Information. , Subdivided into 7 types such as Learning, Kids, etc., and made 48 channels of channel patterns by 'Channel's Genetic Code' by 30 minutes every 24 hours. The similarity with the viewer pattern is calculated in the same way as the calculation of the gene sequence agreement, and additional weights are provided for each channel.

That is, even if the same news, it is preferable to give more weight to the program provided by the channel that viewers frequently watch.

There may be a variety of ways to calculate the similarity, for example there may be a way to calculate the degree of agreement of the gene sequence, that is, simply calculate the degree of matching of the code in the 48 time domains, and also the two hours before and after the current time zone. We can suggest how to change the number of nine arrays to match.

In this way, for example, a real-time preference function value for all N = 10,000 channels is calculated by the server, and the top 10-20 channel and program list is converted into a TV terminal (TV, STB or PVR, etc.). If you send it in the form of (XML), the TV terminal stores it in the preferred channel storage space so that the viewer shows a window at the top of the screen when desired. This window lets you switch directly to that channel.

In this case, viewers set up a specific program (such as a specific drama or program name) or a specific category viewing pattern information (movie type, drama type, entertainment type, sports type, information type, education type, etc.) set through the TV terminal or service website. Reflecting the child type, etc.) is reflected in the calculation of program importance or viewing pattern weight.

In addition, in case of a PVR having a recording function, if a previous broadcast program is also recorded, a preference function value may be calculated in a similar manner to participate in the preference channel ranking. Alternatively, you can use this feature to automatically record when the value of the preference function exceeds a specified value or rank.

In addition, if the preference ranking method is applied to the recommendation of a favorite program on an IPTV or video-on-demand (VOD) type TV, or has a recording function of the front part of a program introduced to speed up channel change or streaming, Can be used to select programs with high preference.

In addition, when the computing power of the TV terminal is increased in the future and detailed information such as the importance of each category can be obtained in real time in the received EPG information, such a function may be implemented in the terminal.

In addition, when the spread of the TV terminal equipped with such bidirectional communication function exceeds a certain statistical scale, the real-time viewing information is automatically collected and the program viewing rate is automatically calculated in real time, and the viewer's viewing pattern weight by program is calculated based on the viewing history information. You can give real-time rankings. In this case, as an example of the calculated algorithm, a simple real-time channel rating is multiplied by a viewing pattern weight for the channel to rank the channel preference. If there is no viewing pattern weighting function, the ranking may be determined based on a simple real-time channel rating, and the upper ranking channels may be displayed on the TV screen, thereby allowing the viewer to easily select an interesting channel. This method is still applicable to two-way digital cable broadcast service providers.

As described in detail above, a method and system for automatically generating and displaying a preference list of a TV broadcast program according to the present invention are based on priorities calculated in real time based on viewer ratings or other personal preference data for a program that is currently viewable when the TV is viewed. By showing on the TV screen by the top rankings in the era of 100 to 10,000 or more multi-channel, especially when IPTV is enabled, you can watch more than 100,000 channels, real-time what interesting programs are provided in which channels, By providing a list of priority rankings, viewers can select and watch funny programs in the easiest way, such as one-click on the remote control, and download partially downloaded funny programs from an IPTV with a storage device and stream them when selected. When buffering for Can significantly shorten the liver

In addition, service providers can create various revenue models through this service window, such as advertisements and rewards for sponsored channels viewed through this window.

The technical idea of the method for automatically generating and displaying a preference list of a TV broadcast program of the present invention has been described above with the accompanying drawings, but this is by way of example and not by way of limitation. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
