Embodiment

For making object of the present invention, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, scheme of the present invention is described in further detail.

In the embodiment of the present invention, with media data popularization plan for base unit at the uniform velocity throws in control, media data popularization plan comprises multiple media datas with identical popularization theme.In order to meet the at the uniform velocity input demand of media data in media data popularization plan, the related consumer situation of media data popularization plan in t chronomere front in preset time period is added up, throw in probability according to the media data that statistics determines in t+1 chronomere, thus according to this media data input probability, input control is carried out to the media data in media data popularization plan.Here media data can be advertisement.

Be embodiment of the present invention media data at the uniform velocity putting control system schematic diagram see Fig. 1, Fig. 1, this system comprises media data subsystem and controls equipment/device that media data at the uniform velocity throws in, wherein,

Media data subsystem is made up of one or more service equipment.Media data subsystem primary responsibility performs media data popularization plan associative operation, such as, the media data request of receiving media data display platform (such as, when opening a certain webpage of website, triggering media request of data, media data request is sent to the media data subsystem on backstage), the media data current according to media data popularization plan is thrown in probability and is sent to media data to media data display platform, the media data that media data subsystem sends is showed client (user of such as browsing page) by media number display platform, thus realize media data input.Media data subsystem also needs to perform the exposure to the media data of media data popularization plan, click situation carries out the operation such as statistics and expense deduction, and accordingly by the related consumer message notice of media data popularization plan to controlling the equipment at the uniform velocity thrown in of media data, wherein, the related consumer information of media data popularization plan comprises: media data promoter corresponds to the Spending Limit of media data popularization plan in preset time period, media data popularization plan is at the Spending Limit of preset time period, media data popularization plan is in the amount of consumption etc. of each chronomere.

Control the equipment that media data is at the uniform velocity thrown in, be responsible for when last chronomere terminates or a rear chronomere starts, the popularization plan of computing medium data throws in probability at the media data of a rear chronomere, thus makes media data subsystem throw in the media data of probability to the popularization plan of media data display platform propelling movement media data according to this media data.In specific implementation, the equipment that control media data is at the uniform velocity thrown in can obtain the related consumer information of media data popularization plan in real time from media data subsystem, and the related consumer information of media data popularization plan is added up, obtain the account amount of consumption of media data promoter in each preset time period Zhong Qian t chronomere, by the account balance of t chronomere, and described media data popularization plan is in the statistics (specifically will be described in subsequent embodiment) such as overall consumption volume of front t chronomere, and then calculate the available balance of described media popularization plan by t chronomere according to statistics, and calculate the media data input probability of media data popularization plan in t+1 chronomere based on this available balance, thus make media data subsystem can carry out input control according to this media data input probability to the media data in media data popularization plan.

Be that the embodiment of the present invention controls the method flow diagram at the uniform velocity thrown in of media data see Fig. 2, Fig. 2, the method mainly comprises the following steps:

Step 201, obtain media data promoter in preset time period, correspond to the Spending Limit of media data popularization plan and the described media data popularization plan Spending Limit in preset time period.

Media data is thrown in and is belonged to paid service, usually needs to set Spending Limit, then stops media data throwing in when consumption is in excess of the quota.When media data refers to advertisement, correspondingly, media data promoter is advertiser, and the advertisement in media data popularization plan all belongs to same advertiser.

In actual applications, media data promoter can participate in multiple media data popularization plan, and has an accounts of consumption, wherein store media data promoter for participate in multiple media data popularization plan and stored in the prepayment amount of consumption.

Under normal circumstances, media data promoter can specify the spending limit of each media data popularization plan of participation, after sharing the duration of this media data popularization plan equally, just can obtain the Spending Limit that media data promoter corresponds to this media data popularization plan in preset time period.

In addition, media data popularization plan itself also has clear and definite spending limit, after sharing the duration of this media data popularization plan equally, just can obtain the Spending Limit of this media popularization plan in preset time period (such as 1 day).

In the embodiment of the present invention, need to obtain from media data subsystem in advance media data promoter and in preset time period, correspond to the Spending Limit of media data popularization plan and described media data popularization plan at the Spending Limit of preset time period, throw in probability calculation for follow-up media data.

Step 202, in each preset time period, the statistics account amount of consumption of media data promoter in front t chronomere, by the account balance of t chronomere and described media data popularization plan at the overall consumption volume of front t chronomere, calculate the available balance of described media popularization plan by t chronomere according to statistics.

Each preset time period should comprise the duration of at least one chronomere.

In actual applications, media data exposure each time, clickedly each time all can have the corresponding amount of consumption as the case may be.Media data extension system can add up by the spending limit to each media data promoter according to the concrete exposure of media data and click situation in running, obtain this media data promoter in preset time period by t chronomere (t be greater than 0 natural number, chronomere can be wonderful, minute, hour etc.) the account amount of consumption and account balance by t chronomere; Can also add up the overall consumption volume of media popularization plan by t chronomere in preset time period according to the concrete exposure of media data and click situation simultaneously.

Statistics obtains the statistics account amount of consumption of media data promoter in front t chronomere and the account balance by t chronomere, and described media data popularization plan is after the overall consumption volume of front t chronomere, can according to the available balance of statistics determination media data popularization plan in this preset time period, concrete grammar is: compare the account balance of media data promoter by t chronomere, the difference of the Spending Limit of media data promoter in preset time period and the account amount of consumption in front t chronomere, described media data popularization plan is in the size of the Spending Limit of preset time period with the difference of the overall consumption volume in t chronomere, minimum value is wherein defined as the available balance of described media popularization plan.
