Detailed ways

Each vendor typically views historical user data of an electronic program based on user history (e.g., viewing time of an electronic program, number of clicks, ratings, etc.) and recommends relevant electronic programming to the user. However, this method has the problem of inaccurate recommendation.

For example, when evaluating the user's preference, because the time range of different users watching electronic programs is uncertain, collecting enough historical user data will expand the time range, and the user will watch the electronic programs of the same history in a larger time range. Different preferences may result in the user not necessarily still enjoying the electronic program of historical viewing in a small time range, so that the recommended electronic program is not necessarily the electronic program desired by the user, and is an invalid push, thereby causing the push. Electronic programs are less accurate and waste resources.

If the user wants to obtain an electronic program of interest, he often cuts the station, selects the station, or performs a large number of search operations, which is cumbersome and time consuming.

In the process of recommending an electronic program, since the time span required for collecting user data of different users is long, the user's preference for the electronic program may change, resulting in an invalid push problem, so that the accuracy of the recommended electronic program is low and waste. The method for acquiring an electronic program of interest is cumbersome and time consuming. The embodiment of the present application proposes a method for generating an electronic program guide on a smart terminal and a corresponding intelligent terminal.

1 is a flow chart showing the steps of a method for generating an electronic program guide on a smart terminal according to an embodiment of the present application, which may specifically include the following steps:

Step 101: When the smart terminal plays the electronic program, measure the distance between the smart terminal and the user.

In a specific implementation, the embodiment of the present application can be applied to an intelligent terminal, where the smart terminal includes a television, a computer, and the like.

In an embodiment, the television can receive a television signal (such as an analog signal). For example, the television can be an LCD (Liquid Crystal Display) television, an LED (Light Emitting Diode) television, a plasma TV, or the like. Wait.

Further, the TV may have a fully open platform, equipped with an operating system, for example, an Android system, an IOS system, a Windows system, etc., and the user may install and uninstall a third party such as an application or a game. Applications provided by service providers (ie, third-party applications), through which such functions are continuously expanded, and can be accessed via a network cable or a wireless network.

In another embodiment, the television may not receive a television signal (such as an analog signal), but may be connected to an electronic device such as a computer or a mobile phone, and input information such as video or games through an electronic device such as a computer or a mobile phone, or Perform other interactions.

In the embodiment of the present application, the user selects an electronic program (such as a variety show, a TV show or a sports event, etc.) to play on the television. In the process, each time interval (such as 1 minute) can be passed through Bluetooth, infrared or Image acquisition and other methods measure the distance between the TV and the user.

It should be noted that the distance between the TV and the user refers to the physical actual distance, such as 1 meter, 2 meters, and the like.

Step 102: Determine, according to the distance and the duration of the distance, whether the electronic program is a target program that the user likes.

In the embodiment of the present application, the distance between the intelligent terminal and the user is collected in real time, and the duration of the distance is maintained, and the distance change during the user watching the electronic program is analyzed, and the behavior during the user viewing process is analyzed, and the behavior may be to some extent. Respond to the user's preference for electronic programming.

For example, users tend to sit on sofas and chairs for favorite electronic programs, and pay attention to the TV. At this time, the distance between the user and the smart terminal is moderate and stable, and the duration of maintaining a certain distance is long. Suitable for watching electronic programs.

For another example, the user may do other things for the electronic program that does not like the user. Since the user does not pay attention to the smart terminal and does other things, the user may move frequently, and the distance between the user and the smart terminal is small or large, and unstable. Keeping a certain distance for a short duration is not suitable for watching electronic programs.

Thereby, the electronic program that the user may like is excavated as the target program by the behavior of the user.

Step 103: If the electronic program is the target program that the user likes, generate an electronic program guide based on the recommended program similar to the target program.

In a specific implementation, information such as the name and type of the target program may be stored in a database and sent to a content server in the background, and the similarity is high (characterized as the similarity is higher than the preset similarity threshold). The electronic program, as a recommended program, is recommended to the user.

In one embodiment, an electronic program of the same type as the target program may be used as the recommended program.

In another embodiment, the information of the electronic program (such as channel information, title, type, description information, start time, length, thumbnail, etc.) is represented by a vector, and the vector of the target program and the vector of other electronic programs are calculated. The vector distance between the two, and the recommended electronic program is selected based on the vector distance, thereby obtaining the recommended program.

Certainly, the search manner of the recommended program is only an example. In the implementation of the embodiment of the present application, the search manner of other recommended programs may be set according to actual conditions, for example, collaborative filtering, matching from the network, or matching from the server, etc., the present application. The embodiment does not limit this. In addition, in addition to the above-mentioned manner of searching for the recommended program, those skilled in the art may also use other methods for searching for recommended programs according to actual needs, which is not limited in the embodiment of the present application.

In the embodiment of the present application, after processing the information of the recommended program, the content server generates an Electronic Program Guide (EPG), sends it to the smart terminal for display, and pushes the recommended program to the user.

Television broadcasts transmitted by terrestrial, cable or satellite transmissions, while playing television audio and video signals, broadcast data carrying other information, including electronic program guides.

As shown in FIG. 2, in an example of an electronic program guide, the data structure may include a domain (attribute) such as a channel, a broadcast time, a title, and the like, and may also include a domain (attribute) such as a category, a description, a cast, and a thumbnail. .

For these recommended programs, a viewing period may be set, and if the recommended program is viewed by the user during the viewing period, that is, the recommended program is played during the viewing period, the data deemed to be valid is retained if the viewing period is within the viewing period. If the user does not watch the recommended program, that is, the recommended program does not play during the viewing period, it is regarded as invalid data, and is deleted, so that the recommended program can be dynamically adjusted according to the user's viewing condition, and the effectiveness and effectiveness of the recommended program are ensured. Sex.

When the smart terminal plays the electronic program, the embodiment of the present application measures the distance between the smart terminal and the user, and does not need to consider whether other users other than the user view the electronic program, and does not need to view the electronic program in combination with other users. The user data recommends the electronic program to improve the real-time performance of the user data when recommending the electronic program, and then determines the electronic program to be the target program of the user's preference according to the distance and the duration of the distance, and maintains the length of the distance distributed in the playing electronic program. In the process, the authenticity of the viewing behavior of the user during the playing of the electronic program can be better reflected, so as to improve the accuracy rate of the user's preference for the target program, and finally, based on the recommended program when the matching target program and the recommended program are similar. Generate program guides to achieve effective push of recommended programs and improve the accuracy of recommended electronic programs.

Referring to FIG. 3, a flow chart of steps of a method for generating an electronic program guide on a smart terminal according to another embodiment of the present application is shown. Specifically, the method may include the following steps:

Step 301: After receiving the signals sent by the signal transmitter held by the user, the receiving points located at different positions of the smart terminal respectively calculate, after the signal strength of the signal is used as a parameter, the receiving point and the The distance of the user.

Step 302: The virtual circular trajectory is represented by a radius of the receiving point and a distance between the receiving point and the user, and an intersection of the virtual circular trajectory is located.

Step 303: Set a distance between the intersection point on the same side of the screen of the smart terminal and a target location on the screen as a distance between the smart terminal and the user.

In the embodiment of the present application, optionally, one or more Bluetooth components are set as receiving points on the smart terminal, and two Bluetooth components are set as an example, which may be distributed at two corners or other positions below the screen of the smart terminal.

The user has a Bluetooth terminal (ie, a terminal having a Bluetooth module, such as a headset, a mobile phone, a wristband, a watch, etc.) as a signal transmitter that is worn or loaded during the viewing of the electronic program.

After the electronic terminal plays the electronic program, the different receiving points set on the intelligent terminal establish a connection with the signal transmitter of the user, and the signal transmitter of the user sends the RSSI (Received Signal Strength Indication) to the receiving point every time interval (for example, 1 minute). , received signal strength indication).

Based on the principle that the radio signal is regularly attenuated as the distance increases, the distance between the receiving point and the signal transmitter can be measured based on the RSSI.

In a specific implementation, the relationship between RSSI and distance is as follows:

RSSI=-(10×n×lgd+A)................................................[1]

Where n is the signal propagation constant (or propagation coefficient), d is the distance from the sender, and A is the signal strength when it is 1 m from the sender.

The accuracy of d is affected by the actual value of n and A. A is an empirical parameter, which can be obtained by measuring the RSSI of the signal at 1 m from the sender. n is a parameter used to describe the decrease in signal strength as the distance increases. The size depends on the specific environment. In order to get the preferred value of n, you can place the reference node first, and then try to find the value of n that suits the current specific environment with different values.

In a specific implementation, the distance between the intelligent terminal and the user can be calculated by combining the results of one or more measurements to reduce the measurement error.

In one embodiment, the virtual circular trajectory is generated with the receiving point as the center and the distance as the radius.

Positioning the intersection of different virtual circular trajectories, and setting the distance between the target position on the screen of the smart terminal (such as the center point of the screen of the smart terminal, the midpoint of the left edge, the midpoint of the upper edge, and the intersection) and the intersection point The distance between the smart terminal and the user.

Specifically, when there are at least two receiving points, correspondingly, the receiving point is centered, and the virtual circular trajectory generated by the distance between the receiving point and the user is also at least two, in two virtual Among the two intersections of the circular trajectory, the intersection point on the same side of the screen of the smart terminal is selected, and the distance between the intersection point and the target position on the screen is set as the distance between the user and the smart terminal, so that more The signals received by the receiving points correct the distance between the user and the intelligent terminal to overcome the problem of inaccurate positioning.

Optionally, among the plurality of intersections located by the at least two virtual circular trajectories, selecting a plurality of intersection points on the same side of the screen of the smart terminal, and selecting each distance by comparing the distance between each intersection point and the same target position on the screen, a distance in the distance from the user to the receiving point to select an intersection point approaching the user position, wherein the distance between the user and the receiving point may be through a plurality of intersections with the same side of the screen of the smart terminal The average distance or weighted average of the distance between users is calculated.

Of course, in addition to calculating the distance by the intersection point, the distance may be set in other ways, for example, the maximum value, the minimum value, or the average value of the distance, and the like, which is not limited by the embodiment of the present application.

In addition, the method for measuring the distance is only an example. When implementing the embodiment of the present application, other methods for measuring the distance may be set according to actual conditions, for example, collecting images for face recognition, and if the recognition is successful, the face data is located. The direction of the infrared signal is measured, the distance between the television and the user is measured, and the like, which is not limited by the embodiment of the present application. In addition, in addition to the above method for measuring the distance, other methods for measuring the distance may be used by those skilled in the art according to actual needs, and the embodiment of the present application does not limit this.

Assuming that the distance is D _i , if the distance between the smart terminal and the user is measured every interval (for example, 1 minute), in the process of the user watching the electronic program, a smart terminal and the user can be calculated in real time. Group distance (D ₁ , D ₂ , D ₃ , D ₄ , D ₅ ... D _i ), if the measurement distance fails, it can be filled by default values.

Step 304, recording a first duration of maintaining the first distance, and/or recording a second duration of maintaining the second distance.

The measured distance between the smart terminal and the user includes a first distance within a preset range and a second distance outside the preset range.

Applying the embodiment of the present application, the range of watching television can be preset, such as 3 meters to 6 meters. If the user is within the range, the electronic program may be viewed more. If the user is not in the range, the user may not be watching. Electronic program.

Assuming that the first distance is marked as 1 and the second distance is marked as 0, the implementation can calculate a set of distances between the intelligent terminal and the user (D ₁ , D ₂ , D ₃ , D ₄ , D ₅ ... D _i ) Convert to 1,0 discrete data.

In addition, the distance between the user and the smart terminal is measured cyclically multiple times, and the time that each measured distance is maintained is its duration, including the first duration of maintaining the first distance and the second duration of maintaining the second distance.

For example, if the distance is measured periodically, and the distance is measured every 1 second, the first duration and the second duration are both 1 second.

Step 305: Analyze, according to the first distance and the first duration, and/or according to the second distance and the second duration, an behavior state of the user viewing the electronic program.

In the embodiment of the present application, in consideration of a user temporarily watching an electronic program during viewing of an electronic program, the user may view the electronic based on the first distance and the first duration, or the second distance and the second duration. The state of behavior at the time of the show.

In one embodiment, when the user effectively watches the electronic program for a certain percentage of the duration of the program (eg, 80%), the user is in a stable viewing state.

In an embodiment of the present application, optionally, step 305 may include the following sub-steps:

Sub-step S11, if the first distance and the first duration meet the first viewing condition, or the second distance and the second duration do not meet the second viewing condition, determining that the user views the The behavior state of the electronic program is a stable viewing state.

The first viewing condition includes: accumulating a first ratio of the first accumulated duration obtained by the first duration to exceed a first ratio (eg, 90%) of the duration of the program of the electronic program.

The second viewing condition includes one or more of the following:

1. The second cumulative time length obtained by cumulatively calculating the second time length exceeds a second ratio (eg, 10%) of the sum of the first accumulated time length and the second accumulated time length.

2. The number of invalid intervals exceeds a preset number threshold, and the third accumulated duration obtained by the second duration in the cumulative calculated invalid interval exceeds the first sub-program duration (eg, 5 minutes) within the duration of the program. Wherein, the invalid interval is composed of a continuous second distance, for example, when the distance is measured every 1 second, if the distance measured for 5 consecutive seconds is outside the preset range (for example, greater than 5 meters), then the The 5-second interval is considered an invalid interval.

3. The fourth cumulative time length obtained by calculating the first time length corresponding to the moving distance is cumulatively calculated, and exceeds a third ratio (eg, 10%) of the sum of the first accumulated time length and the second accumulated time length. The moving distance is a first distance in which the distance difference exceeds a preset distance threshold.

Of course, the foregoing first viewing condition and the second viewing condition are only examples. In the implementation of the embodiment of the present application, other first viewing conditions and second viewing conditions may be set according to actual conditions, which is not limited by the embodiment of the present application. In addition, in addition to the first viewing condition and the second viewing condition, the first viewing condition and the second viewing condition may be used by those skilled in the art according to actual needs, and the embodiment of the present application does not limit this.

In an embodiment of the present application, optionally, the sub-step S11 may further include the following sub-steps:

Sub-step S111, setting a standard distance for the user to view the target program.

In a specific implementation, a continuous first distance within a second sub-program duration (eg, 10 minutes) of the program duration and a distance difference of 0 may be found.

If the accumulated value obtained by the cumulative calculation of the first duration corresponding to the continuous first distance is between the second sub-program duration and the third sub-time length less than the second sub-length (eg, 5 minutes), the first distance is set to Standard distance.

Sub-step S112, calculating a degree of stability for characterizing the user within the preset range based on a difference between the standard distance and the first distance.

In the embodiment of the present application, the standard distance can be used as a standard, and the degree of dispersion and stability of the distance during the process of viewing the electronic program by the user are analyzed according to the principle of variance and standard deviation.

Further, the degree of dispersion can be calculated by the following formula:

Where S is the degree of dispersion, m is the number of distances, D _i is the distance (group) corresponding to the electronic program, and D _x is the standard distance. For the summation symbol,

The degree of stability can be calculated by the following formula:

CV=S/D _x *100%..........................................[3]

Among them, CV is the degree of stability, S is the degree of dispersion, and D _x is the standard distance. * indicates a multiplication sign.

Sub-step S113, matching the similarity of the target program and the recommended program when the degree of stability is not less than a preset value for characterizing the stable viewing state.

Sub-step S114, when the degree of stability is less than the preset value, the target program is deleted.

In a specific implementation, it may be determined whether the degree of dispersion is less than a preset discrete threshold (eg, 0.5 meters) and/or whether the degree of stability is less than a preset stable threshold (eg, 8%). If yes, it is determined that the electronic program is valid; if not, it is determined that the electronic program is invalid, and the electronic program is deleted.

Step 306, when analyzing that the behavior state is in a stable viewing state, determining that the electronic program is a target program that the user likes.

If the behavior state of the user is a stable viewing state, it means that the user stably watches the electronic program, and then the electronic program can be determined to be an electronic program that the user likes.

Step 307: Generate an electronic program guide based on the recommended program similar to the target program.

In an embodiment of the present application, when a plurality of users view the electronic program, querying a user identifier of the user, searching for a recommended program whose similarity is higher than a preset threshold based on the target program that the user identifier should be; using the recommended program An electronic program guide is generated for the user corresponding to the user identification.

In this embodiment, a user identifier may be communicated between the user's Bluetooth terminal and the smart terminal, and different electronic program guides may be generated for different users for different user identifiers.
