Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises," "comprising," or any other variation thereof, in the description and claims of this application are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "such as" in an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion.
Referring to fig. 1, fig. 1 is a flowchart of a multimedia information delivery method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
The media in the embodiment of the present invention may be media for delivering multimedia information, and specifically may be media devices for delivering multimedia information installed in places such as shopping malls, office buildings, communities, hospitals, and the like, for example: a programmable display device.
The target media may be a certain media or a plurality of media in a certain region.
Preferably, the target media is a media collected in a target area. Therefore, multimedia information release management can be performed according to regions, and complexity of multimedia information release is reduced.
For example: in the embodiment of the present invention, media may be divided into a plurality of media sets according to information such as brands and models of the media, and each media set may include media devices in one or more regions. For example: the media collection is brand a media, and the target media can be all media of brand a media in city a.
It should be noted that, in the embodiment of the present invention, media is taken as media of a certain media set in a certain area, for example: where the region is a city, the media may be represented as < tu, city >, where tu represents media information (e.g., brand A media) and city represents city information.
It should be further noted that, in the embodiment of the present invention, the multimedia information may be information content that can be delivered on a medium, for example: advertising multimedia information (which may be referred to simply as advertisements).
In addition, the first traffic information and the second traffic information may be configured in advance, so that the first traffic information and the second traffic information are obtained from the local when step 101 is executed. Of course, the first traffic information and the second traffic information may also be set by a remote device, so that the first traffic information and the second traffic information are obtained from the remote device when step 101 is executed.
In addition, the at least one piece of multimedia information may be multimedia information allocated to the target medium, that is, the first traffic information may indicate the multimedia information allocated to the target medium and a deliverable traffic of each piece of multimedia information. The deliverable traffic herein may also be referred to as distributed traffic distributed in the target media.
The distribution flow rate corresponding to the people flow rate of the target medium may be a distribution flow rate having a specific correspondence relationship with the people flow rate of the target medium, for example: the distribution flow of the target media is in a direct proportion relation with the human flow, or the corresponding relation between the flow ratio and the human flow ratio, and the like.
It should be noted that the distributed traffic according to the embodiment of the present invention may be understood as traffic that needs to be delivered, and further, the distributed traffic may be traffic in a time dimension, and the deliverable traffic may be traffic in a space dimension. For example: the distributed traffic may be distributed traffic of the target medium at each hour of a day, and the deliverable traffic may be deliverable traffic of each multimedia message on the target medium at the day.
The total dischargeable flow rate on the target medium may be equal to the distribution flow rate, or the total dischargeable flow rate may not exceed the distribution flow rate, or a difference between the total dischargeable flow rate and the distribution flow rate may be within a predetermined range.
It should be noted that this step is to determine whether the target multimedia information is delivered on the target media at the current time, that is, the target multimedia information may have been delivered on the target media before step 102 is executed, or the target multimedia information has not been delivered on the target media before step 102 is executed. Specifically, step 102 may be executed before the target multimedia information is released each time, so as to ensure that the multimedia information released on the target media meets the first traffic information and the second traffic information.
And determining whether the target multimedia information can be currently released on the target media according to the first flow information and the second flow information, wherein if the target multimedia information is currently released on the target media and meets the first flow information and the second flow information, it is determined that the target multimedia information can be currently released on the target media, and if the target multimedia information is currently released on the target media and does not meet the first flow information and/or the second flow information, it is determined that the target multimedia information cannot be currently released on the target media. Or, if the current delivery flow delivered on the current target media of the target multimedia information meets the first flow information and the second flow information, it is determined that the target multimedia information can be delivered on the target media currently, and otherwise, it is determined that the target multimedia information cannot be delivered on the target media currently. For example: and if the current residual flow in the deliverable flow of the target multimedia information in the first flow information is larger than the current delivery flow, and the current residual flow in the distributed flow in the second flow information is larger than the current delivery flow, determining that the target multimedia information can be delivered on the target media currently.
In the above steps, since the distribution flow of the target media corresponds to the pedestrian flow of the target media, the multimedia information can be delivered according to the pedestrian flow, the delivery effect of the multimedia information can be improved, and the requirements of users (such as advertisers) of the multimedia information can be met.
It should be noted that the multimedia information delivery method provided in the embodiment of the present invention may be applied to a Demand-Side Platform (DSP) Platform, for example: a focused screen DSP product, which is not limited to this, for example: the method can also be applied to other multimedia information release management devices or platforms.
In addition, the multimedia information in the embodiment of the present invention may be outdoor programmed multimedia information, for example: and D, DSP advertisement.
As an optional implementation manner, the determining whether target multimedia information is currently delivered on the target media according to the first traffic information and the second traffic information includes:
if the deliverable flow of the target multimedia information on the target media is not consumed and the distributed flow of the target media is not consumed, determining that the target multimedia information is delivered on the target media currently;
and if the deliverable flow of the target multimedia information on the target media is consumed or the distributed flow of the target media is consumed, determining that the target multimedia information is not delivered on the target media currently.
Wherein, the above consumption can be understood as actually delivered, for example: the fact that the deliverable flow of the target multimedia information on the target media is not completely consumed can be understood as that the deliverable flow of the target multimedia information on the target media is not completely delivered.
In this embodiment, it may be determined that the target multimedia information is currently delivered on the target media only when the deliverable traffic is not consumed and the distribution traffic is not consumed. Thus, the delivery of the multimedia information can be ensured not to exceed the delivery flow and the distribution flow of the media.
Further, the allocation traffic may include allocation traffic of a plurality of different time periods, so that when step 202 is executed, the allocation traffic may be determined according to the allocation traffic of the current time period, so as to ensure that the allocation traffic of each time period does not exceed the standard.
As an optional implementation manner, before the obtaining the first traffic information and the second traffic information of the target media, the method further includes:
classifying a plurality of media including the target media into importance levels;
and performing distributable flow distribution on the multimedia information to be distributed according to a distribution principle that the importance level of the distributable media of each multimedia information in the multimedia information to be distributed is from high to low to obtain first flow information of each media, wherein the multimedia information to be distributed at least comprises at least one piece of multimedia information, and the distributable media of each piece of multimedia information is the media in the plurality of media.
The multiple media may be all or part of a certain area, such as: the importance level of all media in a country or region may be divided.
In addition, the above-mentioned division of the importance level may be an importance level division according to parameters of media, history information, advertisement performance or human traffic, and the like. It should be noted that ranking media may also be referred to as ranking media traffic. For example: the plurality of media may be divided into 'backbone traffic', 'dynamic traffic', 'complementary traffic', where the 'backbone traffic' is higher in importance level than the 'dynamic traffic' and the 'dynamic traffic' is higher than the 'complementary traffic'. Of course, this is merely an example, for example: further levels may be divided.
The multimedia information to be distributed may be multimedia information corresponding to all or part of a multimedia information plan in a multimedia information library, and the deliverable media of the multimedia information may be media satisfying the delivery plan of the multimedia information, for example: the multimedia information delivery plan of a certain multimedia information is delivered in the market of city a, and the deliverable media of the multimedia information includes the media in the market of city a.
The distribution of the deliverable traffic of the multimedia information to be distributed may be that the multimedia information is preferentially distributed on a medium with a high importance level in the deliverable media, and if the deliverable traffic distributed on the medium with the high importance level does not reach the budget traffic of the multimedia information, the multimedia information is distributed on a medium with a low importance level in the deliverable media until the budget traffic of the multimedia information is distributed completely, or the available traffic of the deliverable media is distributed completely. For example: the target multimedia information is distributed to the medium 1 preferentially if the importance level of the medium 1 is higher than that of the medium 2 and the importance level of the medium 2 is higher than that of the medium 3, the target multimedia information is distributed to the medium 2 continuously if the distributed deliverable flow on the medium 1 does not reach the budget flow of the multimedia information of the target multimedia information, the distribution is quitted if the deliverable flow distributed on the medium 2 and the deliverable flow of the medium 1 meet the budget flow of the multimedia information, and the distribution is continued to the medium 3 until the budget flow of the multimedia information is distributed completely or the available flows of the medium 1, the medium 2 and the medium 3 are distributed completely.
In this embodiment, the traffic of the multimedia information can be preferentially distributed to the media with high importance level, so that the delivery effect of the multimedia information can be further improved.
Further, the allocating the deliverable traffic of the multimedia information to be allocated according to the principle that the importance level of the deliverable media of each multimedia information in the multimedia information to be allocated is from high to low may include:
determining a distribution sequence according to the throwing area of each piece of multimedia information in the multimedia information to be distributed, wherein the smaller the throwing area in the distribution sequence is, the more preferential the distribution is;
in the distribution sequence, according to a distribution principle that the importance level of the deliverable media of each multimedia information is from high to low, the deliverable traffic of the multimedia information to be distributed is distributed in sequence to obtain first traffic information of each media.
The placeable area of the multimedia information may be an area that satisfies a placement plan of the multimedia information, for example: the delivery plan of a certain multimedia information is delivered nationwide, and the delivery available area of the multimedia information of the delivery plan of the multimedia information is nationwide.
The distribution of multimedia information having a smaller placeable area is prioritized as the distribution order is in the order from smaller placeable areas to larger placeable areas, that is, multimedia information having a smaller placeable area is preferentially distributed.
After the distribution sequence is determined, the distributable flow of each multimedia message can be distributed according to the distribution principle that the importance level of the distributable media of the multimedia message is from high to low.
In this embodiment, since the multimedia information having a small placeable area is preferentially distributed, the distribution of all the multimedia information can be made to meet the corresponding multimedia information placement plan, so as to further improve the multimedia information placement effect.
The following media are taken as urban area media < tu, city >, and the important levels are divided into 'trunk traffic', 'dynamic traffic' and 'complementary traffic' for example, and specifically refer to fig. 2:
step one, pre-sorting all multimedia information release plans (planes) in a multimedia information library from small to large (namely single city orientation, multi-city orientation and national through delivery) according to the oriented city (city) range of a release area;
step two, grading a plurality of media < tu, city > flows into 'main flow', 'dynamic flow' and 'complementary flow';
step three, traversing each delivery plan of the multimedia information, and filling the budget traffic of the multimedia information by using the traffic of the deliverable media of the delivery plan of the multimedia information, wherein filling can also be understood as allocating the budget traffic of the multimedia information to the deliverable media, and the meaning of the filling can be whether the currently available traffic of the deliverable media can cover the budget traffic of the multimedia information; the available flow value of the media can be obtained from the statistical average value of the previous N days to subtract the distributed flow, and the specific distribution scheme is as follows:
a) Filling trunk flow is preferentially used, and if the trunk flow is filled, quitting and recording the distributed flow; that is, the multimedia information is preferentially distributed to the backbone traffic, so as to obtain the deliverable traffic (or referred to as distributed traffic) of the multimedia information on the backbone traffic medium.
b) If the trunk flow is insufficient, the trunk flow and the dynamic flow are used for filling, the proportion of the dynamic flow is gradually enlarged according to the step length of 10% (of course, other numerical values can be used), until the current plan can be met, the flow is exited if the current plan is met, and the distributed flow is recorded; the step can be that when the current available flow of the backbone flow is smaller than the budget flow of the multimedia information, the multimedia information is distributed to the backbone flow and the dynamic flow, so as to obtain the deliverable flow of the multimedia information on the backbone flow media and the dynamic flow media.
c) When the current plan can not be met, the complementary flow is started, and the main flow, the dynamic flow and the complementary flow are used for filling; if the flow rate meets the requirement, quitting and recording the distributed flow rate; if the current available flow of the backbone flow + the dynamic flow is smaller than the budget flow of the multimedia information, allocating the flow which is not allocated in the budget flow of the multimedia information to the complementary flow, and if the backbone flow + the dynamic flow is 100% + the complementary flow reaches the budget flow of the multimedia information, completing the allocation, thereby obtaining the deliverable flow of the multimedia information on the backbone flow media, the dynamic flow media and the complementary flow media.
d) If the flow rate cannot be met, filling the flow rate by using the flow rate which can be distributed currently, directly exiting even if the flow rate cannot be fully filled, and recording the distributed flow rate; if the backbone flow, the dynamic flow 100% + the complementary flow cannot reach the budget flow of the multimedia information, the allocation is also exited, and the allocated flows on each media are recorded.
Step four, summing up each media < tu, city > to obtain total deliverable flow (used _ PV) of the current day, which can also be called distributed flow, that is, the < tu, city > distribution PV value of the produced media < tu, city >, wherein the PV value represents the flow value.
And fifthly, generating a < tu, city, plan, pv > dictionary, wherein the < tu, city, plan, pv > dictionary is a dictionary with spatial dimension and represents the deliverable flow of each multimedia information corresponding to the media < tu, city >, namely the introduced first flow information.
In an optional implementation manner, the allocating the flow rate in step 101 includes: j second unit time distribution flow rates in a first unit time, wherein J is an integer larger than 1, and the total distributable flow rate of the target media in the first unit time is matched with the total distributable flow rate of the target media in the first unit time.
The first unit time may be day, 12 hours, or the like, and the second unit time may be hour, 30 minutes, or the like, and these unit times may be determined according to actual conditions.
The J second unit time distribution flow rates in a first unit time may be, for example: the distribution flow rate per hour of the day.
In addition, since the distribution flow rate in step 101 is a distribution flow rate corresponding to the human flow rate of the target medium, it can be found that the J distribution flow rates of the second unit times also correspond to the human flow rate of the target medium, for example: the J second-unit-time distribution flow rate distribution also corresponds to the human flow rate of the target medium in the J second unit times, and if the J second-unit-time distribution flow rate is large in the second unit time where the human flow rate is large, the J second-unit-time distribution flow rate is small in the second unit time where the human flow rate is small.
In addition, in this embodiment, the first traffic information may include a deliverable traffic of at least one multimedia message on the target medium in the first unit time.
In the embodiment, the second flow information can be further refined, so that the multimedia information can be more accurately released, the multimedia information can be released at a constant speed, and the releasing effect of the multimedia information can be further improved.
Preferably, the second flow information includes a distribution flow that satisfies the following condition:
j flow distribution ratios are matched with J personal flow ratios;
wherein the J traffic allocation ratios include: a ratio of a sum of distributed flow rates of N media in a second unit time J to a total distributed flow rate, where the total distributed flow rate is the total distributed flow rate of the N media in the first unit time, J is an integer from 1 to J, a distribution situation of a human flow rate of the N media in the first unit time matches the same human flow rate distribution information, the N media includes the target media, and N is an integer greater than or equal to 1;
the J personal traffic fraction includes: the proportion of the flow of people in the second unit time j in the flow of people distribution information to the total flow of people, and the total flow of people is the total flow of people in the first unit time in the flow of people distribution information.
The N media may be one or more media having the same or similar traffic distribution conditions in the first unit time, that is, the traffic distribution conditions of the N media may all be represented by the traffic distribution information. For example: the N media can be media of the same brand in different cities, and the media of the brand are all installed in a certain scene (such as an elevator room of a shopping mall or an office building) in the cities, so that the traffic distribution situations of the N media are the same or similar, and further can be represented by the same traffic distribution information.
The traffic distribution information may indicate the traffic per second unit time of any one of the N media, the ratio of the traffic per second unit time to the total traffic per first unit time, or a traffic curve per first unit time.
The ratio of the sum of the distributed flow rates of the N media in the second unit time j to the total distributed flow rate may be a ratio of the sum of the distributed flow rates in any second unit time to the total distributed flow rate, for example: 24 hours a day, 24 traffic distribution accounts are obtained, namely the ratio of the sum of the distribution traffic of N media in each hour to the total traffic distributed all day.
The ratio of the flow rate of people in the second unit time j to the total flow rate of people in the flow rate distribution information may be, for example: 24 hours a day, 24 occupancy ratios of the individual flow are obtained, i.e. the occupancy ratio of the flow in each hour to the total flow throughout the day.
The J traffic allocation ratios may be matched with the J individual traffic ratios, and the J traffic allocation ratios are respectively equal to or similar to the J individual traffic ratios. Therefore, the distribution flow rate ratio is large in the second unit time when the human flow rate ratio is large, and the distribution flow rate ratio is small in the second unit time when the human flow rate ratio is small, and the multimedia information releasing effect is further improved.
Preferably, the second traffic information of the N media may be obtained as follows:
and performing optimization solution by taking the square sum of J difference values of the J flow distribution ratios and the J personal flow ratios as a target, so that the square sum is smaller than a preset threshold value, and obtaining second flow information of the N media.
The J difference values may be obtained by comparing J traffic distribution ratios with corresponding people traffic ratios, respectively.
The preset threshold may be set according to actual conditions or an empirical value, so as to minimize the sum of squares, thereby optimizing the distribution flow of each media in each second unit time, so as to further improve the delivery effect of the multimedia information.
The optimization solution may be a solution using a preset optimization algorithm to obtain an optimal distribution flow rate of each medium in each second unit time.
The second traffic information is exemplified below with the first unit time as day and the second unit time as hour:
step one, the hourly flow of each media < tu, city > in the media collection is counted, namely the hourly flow of the media collection in each city. Of course, the hourly traffic of the media < tu, city > may also be referred to as hourly drop-able traffic of the media < tu, city > (or as hourly original traffic of the media < tu, city >).
And step two, acquiring the hourly human flow value of the media tu, wherein the hourly human flow value of the media tu can be the hourly human flow value of each media < tu, city >.
Step three, optimization solution: calculating the hourly coefficient alpha of each media < tu, city > to obtain hourly distribution flow, so that the sum of the distribution flows of the N media < tu, city > can fit a people flow curve; while ensuring that the sum of the distributed flows for each media < tu, city > is equal to the respective used _ pv. Where used _ pv here represents the total amount of deliverable traffic (alternatively referred to as total allocated traffic) per media < tu, city >. In addition, the hourly coefficient α may represent a coefficient of the hourly allocated flow rate of the media < tu, city > to the hourly original flow rate, where α is any real number from 0 to 1, for example: a value of 0.9 means that the allocated flow of the medium is 90% of the original flow in a certain hour.
The optimization solution described above can be understood as the optimization solution in the above embodiment.
And the mathematical meaning of the fit is: the proportion of the distributed flow in each hour to the distributed flow in the whole day is as close as possible to the proportion of the flow of people in each hour to the flow of people in the whole day, and the sum of squares of the difference values of the two proportions in the whole day is as small as possible. That is, the sum of the distribution flow rates of the N media < tu, city > can be fitted to the human flow curve, and it can be understood that the sum of the squares of the J differences between the J flow distribution ratios and the J individual flow ratios is smaller than the preset threshold.
For example: as shown in fig. 3, tu, city _1, tu, city _2, and tu, city _3 respectively represent the original flow and the distributed flow corresponding to 3 media < tu, city >, wherein the upper line of each small graph represents the original flow and the lower line of each small graph represents the distributed flow. As can be seen from fig. 3, when the distribution flow rates of the 3 media < tu, city > are summed, a distribution flow rate curve is obtained to be fitted with a people flow rate curve, wherein the upper distribution flow rate curve in the lowest graph of fig. 3 and the lower distribution flow rate curve represent people flow rate curves.
And fourthly, generating a < tu, city, hour > dictionary, namely the < tu, city, hour > dictionary is a time dimension dictionary and represents the distribution flow of the media < tu, city > in each hour.
The optimization solving process can be as follows:
the first step is as follows: grouping the media < tu, city > according to the corresponding people flow curve, and grouping the < tu, city > of the same curve into a group, namely obtaining the N media;
the second step: initialization parameters within each group
1. An hourly traffic distribution for media < tu, city > is initialized, i denotes media < tu, city >, j is hour:
tu_city_pv ij ，i＝1，..N；j＝1，...24
2. initialize the hourly parameter for media < tu, city >:
α ij ，i＝1，..N；j＝1，...24
3. initializing media corresponding reserve, i denotes media < tu, city >:
cpm i ，i＝1，...N
4. initializing the total allocated flow of media < tu, city >, i denotes media < tu, city >:
used_pv i ，i＝1，....，N
and predicted total consumption of media groups
5. Initializing a distribution of hourly traffic for the media group, j being an hour
human_flow j ，j＝1，...，24
And total flow of media group corresponding to people flow
The third step: giving an optimization equation with inequality and equality constraints
1. Optimization objective
2. Constraint of equality
3. Inequality constraint
0≤α ij ≤1，i＝1，...，N；j＝1，...，24
The fourth step: solving for alpha based on optimization tool ij ；
The fifth step: and finally, exporting data: distribution traffic pv at hour per media < tu, city > (tu _ city _ hour _ pv)
tu_city_hour_pv ij ＝tu_city_pv ij *α ij
It should be noted that, in the embodiment of the present invention, the optimization solution performed by the solution process is not limited, and the solution process is only a preferred solution. For example: in this embodiment of the present invention, a multi-component hour coefficient α may be configured in advance, where each component hour coefficient α includes an hour coefficient α of each of the N media, and thus one component hour coefficient α is selected from the component hour coefficients α, so that a sum of squares of J differences between the J traffic allocation ratios and the J personal traffic ratios is smaller than a preset threshold.
In addition, in the embodiment of the present invention, the correspondence relationship between the allocated traffic and the human traffic in the second traffic information does not limit the matching between the J traffic allocation ratios and the J personal traffic ratios, and for example: it is also possible that the respective traffic allocation ratio of each medium matches the traffic allocation ratio of people, e.g. the traffic allocation ratio for the target medium at 24 hours is equal or similar to the traffic allocation ratio for the target medium at 24 hours.
In the embodiment of the invention, first flow information and second flow information of a target medium are obtained, wherein the first flow information comprises a jettable flow of at least one piece of multimedia information on the target medium, the second flow information comprises a distribution flow corresponding to a pedestrian flow of the target medium, and a jettable total flow of the target medium is matched with the distribution flow; and determining whether target multimedia information is delivered on the target media currently or not according to the first flow information and the second flow information, wherein the target multimedia information is multimedia information in the at least one piece of multimedia information. Therefore, whether the multimedia information is released or not is determined according to the releasing flow of the multimedia information on the media and the distribution flow corresponding to the pedestrian flow, and the releasing effect of the multimedia information can be improved.
