Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of a method for generating an electronic program guide on an intelligent terminal according to an embodiment of the present invention may specifically include the following steps:
In specific implementation, the embodiment of the invention can be applied to intelligent terminals, and the intelligent terminals comprise televisions, computers and the like.
In one embodiment, the television may receive a television signal (e.g., an analog signal), such as an LCD (liquid crystal Display) television, an LED (Light Emitting Diode) television, a plasma television, or the like.
Further, the television may have a fully-open platform, which is loaded with an operating system, such as an Android system, an IOS system, a Windows system, and the like, and may be used by a user to install and uninstall applications (i.e., third-party applications) provided by third-party service providers, such as application programs and games, and continuously extend the functions of the television through the applications, and may implement internet access through a network cable and a wireless network.
In another embodiment, the television may not receive television signals (e.g., analog signals), but may be connected to an electronic device such as a computer or a mobile phone for inputting information such as video or games, or other interactive operations.
In the embodiment of the invention, a user selects an electronic program (such as a variety program, a TV play, a sports event and the like) to play in a television, and in the process, the distance between the television and the user can be measured in a Bluetooth mode, an infrared mode, an image acquisition mode and the like at certain intervals (such as 1 minute).
It should be noted that the distance between the tv and the user refers to a physical distance, such as 1 meter, 2 meters, etc.
And step 102, determining the electronic program as the target program preferred by the user according to the distance and the duration of measuring the distance.
In the embodiment of the invention, the distance between the intelligent terminal and the user is collected in real time, the duration of the distance is measured, the distance change of the user in the process of watching the electronic program is analyzed, and the behaviors of the user in the process of watching are analyzed, so that the preference degree of the user on the electronic program can be reflected to a certain degree.
For example, a user often sits on a sofa or a chair to pay attention to a television for a favorite electronic program, and at the moment, the distance between the user and the intelligent terminal is moderate, stable, long in duration and suitable for watching the electronic program.
For another example, the user may go to other things for an electronic program that is not preferred, and may often move about because the user does not pay attention to the intelligent terminal, and the distance between the user and the intelligent terminal is small or large, unstable, and short in duration, and is not suitable for watching the electronic program.
Therefore, the electronic programs which the user may like are mined out through the behavior of the user and taken as the target programs.
In specific implementation, the name, type and other information of the target program may be stored in a database, and sent to a content server in the background, so as to search for an electronic program with high similarity (characterized in that the similarity is higher than a preset similarity threshold) on the basis, and recommend the electronic program as a recommended program to the user.
In one embodiment, the recommended program may be an electronic program of the same type as the target program.
In another embodiment, information of the electronic program (such as channel information, title, genre, description information, start time, length, thumbnail, etc.) is represented by a vector, a vector distance between the vector of the target program and vectors of other electronic programs is calculated, and a recommended electronic program is selected by giving the vector distance, thereby obtaining a recommended program.
Of course, the above-mentioned search method for the recommended program is only an example, and when the embodiment of the present invention is implemented, search methods for other recommended programs may be set according to actual situations, for example, collaborative filtering, matching from a network, or matching from a server, and the like. In addition, besides the above search modes of the recommended programs, a person skilled in the art may also adopt other search modes of the recommended programs according to actual needs, and the embodiment of the present invention is not limited to this.
In the embodiment of the present invention, after processing the information of the recommended Program, the content server generates an Electronic Program Guide (EPG), sends the EPG to the intelligent terminal for displaying, and pushes the recommended Program to the user.
The television broadcast transmitted by ground, cable or satellite transmission mode broadcasts data carrying other information, including electronic program guide, while playing television audio and video signals.
As shown in fig. 2, in an example of an electronic program guide, the data structure may include fields (attributes) for channel, broadcast time, title, and possibly category, description, cast, and thumbnail.
For the recommended programs, a viewing period may be set, if the user views the recommended program in the viewing period, that is, the recommended program is played in the viewing period, data regarded as valid is retained, and if the user does not view the recommended program in the viewing period, that is, the recommended program is not played in the viewing period, data regarded as invalid is deleted, so that the recommended program may be dynamically adjusted according to the viewing condition of the user, and the validity and effectiveness of the recommended program are ensured.
The embodiment of the invention measures the distance between the intelligent terminal and the user when the intelligent terminal plays the electronic program, does not need to consider whether other users except the user watch the electronic program, does not need to combine with the user data of the electronic program to recommend the electronic program so as to improve the real-time property of the user data when recommending the electronic program, then determines that the electronic program is a target program preferred by the user according to the distance and the duration of measuring the distance, and the duration of measuring the distance is distributed in the process of playing the electronic program so as to better reflect the reality of the watching behavior of the user in the process of playing the electronic program so as to improve the accuracy rate of evaluating the preference of the user for the target program, and finally generates a program guide based on the recommended program when the target program is matched to be similar to the recommended program so as to realize the effective push of the recommended program, the accuracy of recommending the electronic program is improved.
Referring to fig. 3, a flowchart illustrating steps of another method for generating an electronic program guide on an intelligent terminal according to an embodiment of the present invention may specifically include the following steps:
In the embodiment of the invention, one or more bluetooth modules are arranged on the intelligent terminal as receiving points, and taking two bluetooth modules as an example, the bluetooth modules can be distributed at two corners or other positions below a screen in a moving high school.
The user has equipment such as bluetooth terminal (the terminal that has bluetooth module promptly, such as earphone, cell-phone, bracelet, wrist-watch etc.) as signal transmitter, in the process of watching electronic program, also wears or loads this signal transmitter.
After the mobile terminal plays the electronic program, different receiving points of the television are connected with a signal transmitter of the user, and the signal transmitter of the user sends an RSSI (Received signal strength Indication) to the receiving point at certain intervals (for example, 1 minute).
The distance between the receiving point and the signal transmitter can be measured based on RSSI, using the principle that radio signals regularly decay with increasing distance.
In a specific implementation, the relationship between RSSI and distance is as follows:
RSSI＝-(10×n×lgd+A)
where n represents a signal propagation constant (or propagation coefficient), d represents a distance from the sender, and a represents a signal strength at 1m from the sender.
The precision of d is influenced by the actual values of n and A, A is an empirical parameter and can be obtained by measuring the RSSI signal value at a position 1m away from a sender, n is a parameter for describing the decrease of the signal strength along with the increase of the distance, and the size of n depends on the specific environment. To obtain the preferred value of n, the reference node may be placed first, and then an attempt may be made to find the value of n that is suitable for the particular environment at hand using a different value.
In specific implementation, the distance between the intelligent terminal and the user is calculated by integrating the results of one or more times of measurement, and the measurement error is reduced.
In one embodiment, the virtual circular trajectory is generated with the receiving point as the center and the distance as the radius.
And positioning intersection points of different virtual circular tracks, and setting a distance between a target position (such as any position of a screen center point, a left side edge midpoint, an upper side edge midpoint and the like of the intelligent terminal) on a screen of the intelligent terminal and the intersection points as a distance between the intelligent terminal and a user.
Specifically, when at least two receiving points exist, correspondingly, at least two virtual circular tracks are generated by taking the receiving points as circle centers and taking the distance between the receiving points and the user as a radius, in two intersection points of the two virtual circular tracks, an intersection point on the same side of the screen of the intelligent 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 intelligent terminal, so that the distance between the user and the intelligent terminal can be corrected by using signals received by the plurality of receiving points, and the problem of inaccurate positioning is solved.
Optionally, the multiple intersection points located by the at least two virtual circular tracks are selected from the multiple intersection points located by the at least two virtual circular tracks, the multiple intersection points located on the same side of the screen of the intelligent terminal are selected, and the distances close to the distance between the user and the receiving point in the multiple distances are selected by comparing the distances between the multiple intersection points and the same target position on the screen, so as to select the intersection points approaching the position of the user, wherein the distances between the user and the receiving point can be averaged by taking an average value, a weighted average value and the like.
Of course, besides calculating the distance through the intersection, other ways of calculating the distance may be provided, for example, a maximum value, a minimum value, or an average value of the distance, and the like, which is not limited in this embodiment of the present invention.
In addition, the above method for measuring a distance is only an example, and when the embodiment of the present invention is implemented, other methods for measuring a distance may be set according to actual situations, for example, acquiring an image to perform face recognition, and if the recognition is successful, transmitting an infrared signal in a direction in which the face data is located, measuring a distance between a television and a user, and the like. In addition, besides the above method for measuring distance, a person skilled in the art may also use other methods for measuring distance according to actual needs, and the embodiment of the present invention is not limited to this.
Assume that the distance is DiIf the distance between the intelligent terminal and the user is measured once every a period of time (e.g. 1 minute), a set of distances (D) between the intelligent terminal and the user can be calculated in real time during the process of watching the electronic program by the user1，D2，D3，D4、D5…Di) If the distance measurement fails, population may be by default.
The distance comprises a first distance within a preset range and a second distance outside the preset range.
By applying the embodiment of the invention, the range of watching television, such as 3 meters to 6 meters, can be preset, if the user is in the range, the user is more likely to watch the electronic program, and if the user is not in the range, the user is more likely not to watch the electronic program.
Assuming that the first distance is labeled as 1 and the second distance is labeled as 0, the implementation may calculate a set of distances (D) between the smart terminal and the user1，D2，D3，D4、D5…Di) Converted to 1,0 discrete data.
In addition, the distance between the user and the intelligent terminal is measured repeatedly, and the time consumed by measuring the distance each time is the time length of the time, including a first time length for measuring the first distance and a second time length for measuring the second distance.
For example, the distance is measured periodically, and every 1 second, the first time length and the second time length are both 1 second.
In the embodiment of the present invention, considering that the user may be away from the electronic program for a short time due to an advertisement or other things during the process of watching the electronic program, the behavior state of the user when watching the electronic program may be analyzed based on the first distance and the first duration, or the second distance and the second duration.
In one embodiment, the user is in a stable viewing state when the time for which the user is actively viewing the electronic program reaches a certain percentage (e.g., 80%) of the duration of the program.
In one embodiment of the present invention, step 305 may include the following sub-steps:
and a substep S11, determining that the behavior state of the user watching the electronic program is a stable watching state if the first distance and the first time length are in accordance with a first watching condition, or the second distance and the second time length are not in accordance with a second watching condition.
Wherein the first viewing condition includes:
the sum of the first accumulated time periods obtained by cumulatively calculating the first time period exceeds a first proportion (e.g., 90%) of the program time period of the electronic program.
The second viewing condition comprises one or more of:
1. the accumulated second duration may be accumulated to provide a second accumulated duration that exceeds a second ratio (e.g., 10%) of the sum of the first accumulated duration and the second accumulated duration.
2. The number of the invalid intervals exceeds a preset time threshold, and a third accumulated time length obtained by accumulatively calculating the second time length in the invalid intervals exceeds the first sub-program time length (such as 5 minutes) in the program time length.
Wherein the invalid section consists of consecutive second distances.
3. The fourth accumulated time duration obtained by cumulatively calculating the first time duration corresponding to the moving distance exceeds a third proportion (e.g., 10%) of the sum of the first accumulated time duration and the second accumulated time duration.
The moving distance is a first distance with a distance difference exceeding a preset distance threshold.
Of course, the first viewing condition and the second viewing condition are only examples, and when implementing the embodiment of the present invention, other first viewing conditions and second viewing conditions may be set according to actual situations, which is not limited by the embodiment of the present invention. In addition, besides the first viewing condition and the second viewing condition, a person skilled in the art may also adopt other first viewing conditions and second viewing conditions according to actual needs, and the embodiment of the present invention is not limited to this.
In one embodiment of the present invention, the sub-step S11 further may include the following sub-steps:
and a substep S111, setting a standard distance for the user to watch the target program.
In a specific implementation, consecutive first distances within a second sub-program duration (e.g., 10 minutes) of the program duration and having a distance difference of 0 may be found.
