Description

  The present invention relates to a content distribution determination program, a content distribution determination method, and a content distribution determination device that determine whether or not to distribute content, and in particular, enables a user to comfortably receive content using various content distribution standards. The present invention relates to a content distribution determination program, a content distribution determination method, and a content distribution determination apparatus.

  In recent years, with the increase in the number of users on the Internet and the increase in usage time, there is an increasing need for distribution of various forms of content (Internet advertisements, images, videos, sounds, etc.).

  Here, compared with television radio waves whose communication speed is not greatly affected by changes in the connection environment, in the case of the Internet, online connection is the mainstream, so the connection environment (modem, ISDN (Integrated Services Digital Network) ), ADSL (Asymmetric Digital Subscriber Line), optical fiber, etc.) greatly affects the communication speed (synonymous with bandwidth, the same applies hereinafter).

  For example, the communication speed in a connection environment using a modem is approximately 56 Kbps. The communication speed in the connection environment using ISDN is approximately 64 Kbps. These communication speeds (56 Kbps and 64 Kbps) are classified as low speed.

  On the other hand, the communication speed in the connection environment using ADSL or optical fiber is several hundred kbps to several hundred Mbps, and is classified as high speed.

  FIG. 11 is a diagram showing a conventional communication speed distribution. The distribution shown in FIG. 11 is based on the result of measuring the communication speed in each connection environment for about 3.8 million users possessed by the applicant.

  In the figure, the horizontal axis represents the communication speed. The vertical axis is the number of unique browsers. As can be seen from the figure, most users (78.5%) can obtain a communication speed of 1 Mbps or less, and 21.5% of users can obtain a communication speed of 1 Mbps or more.

  Here, as to whether or not the above-described high-speed content can be acquired comfortably, if the communication speed threshold is set to 50 Kbps, 14.1% of users cannot comfortably acquire the high-speed content. Further, when the threshold value of the communication speed is set to 500 Kbps, 59.1% of users cannot comfortably acquire high-speed content.

  Therefore, the low-speed content is transmitted and the communication speed is measured. When the communication speed is higher than a predetermined threshold, the high-speed content is distributed, and when the communication speed is lower than the predetermined threshold. A technique for displaying low-speed content as it is is disclosed (see Patent Document 1).

  Here, the threshold value may be dynamically set according to the capacity of the low speed content. Specifically, when the communication speed is measured by the low-speed content, the variation in the measurement result increases as the capacity decreases, so the threshold value is changed according to the capacity.

By determining based on the content distribution policy, the content distribution policy of the content holder is satisfied, and the user can comfortably receive the content.

First, the configuration of the content distribution system according to the first embodiment will be described. FIG. 1 is a diagram illustrating a configuration of a content distribution system 20 according to the first embodiment. As shown in FIG. 1, the content distribution system 20 is connected to clients 10 ₁ to 10 _n via a network 30.

The clients 10 ₁ to 10 _n are computer terminals to which content (low-speed content or high-speed content) corresponding to the communication speed is distributed from the content distribution system 20 via the network 30. The computer main body, keyboard, mouse, and It consists of a display. Further, the clients 10 ₁ to 10 _n may be portable information terminals such as mobile phones and PDAs (Personal Digital Assistants) capable of data communication.

The content includes all of various types of information and data that can be distributed, and includes Internet advertisements (banner advertisements, etc.), images, moving images, sounds, and the like.

These clients 10 ₁ to 10 _n are installed with an OS (Operating System), a browser, and multimedia reproduction software. The OS is basic software that performs file management, memory management, input / output management, provision of a user interface, and the like.

  The browser is software for accessing the content distribution apparatus 10 (Web server), performs file transfer by HTTP (Hypertext Transfer Protocol) protocol, decodes hypertext described in HTML (Hypertext Markup Language), and Web It has a function to display pages and contents (Internet advertisement etc.). The multimedia playback software is software for playing back multimedia (video, audio, etc.) on the client.

  Here, regarding the OS, browser, and multimedia playback software, when the version is lower than a predetermined version, the low speed is supported. When the version is equal to or higher than the predetermined version, the high speed is supported.

The content distribution system 20 is a system for distributing content (high-speed content or low-speed content) according to the communication speed on the client 10 ₁ to 10 _n side. The content distribution system 20 first transmits low-speed content to the clients 10 ₁ to 10 _n and calculates the communication speed from the time required for transmission.

When the communication speed is lower than the predetermined threshold, the content distribution system 20 displays the low-speed content on the clients 10 ₁ to 10 _n as they are, and the communication speed is higher than the predetermined threshold. Displays the high-speed content to the clients 10 ₁ to 10 _n for display.

  In the first embodiment, the threshold is set based on information on the communication band of each frame of content. If the content is streaming content whose communication bandwidth changes in time (frame by frame), even if the entire content is small, a large communication bandwidth is required for distribution temporarily, and the communication speed of the communication line If it is small, there is a possibility that the distribution is interrupted. However, by setting a threshold value based on the information of the communication band, it is suppressed, and the user can comfortably execute the content reception.

In this content distribution system 20, a content submission receiving device 40 and a content distribution device 50 are connected via a network 60. Further, the content submission receiving device 40 and the content distribution device 50 send the content data submitted by the clients 10 ₁ to 10 _n or the content producers to the content submission receiving device 40 via the network 30. It is connected to a content submission device (not shown) to be transmitted.

  The content submission receiving device 40 is a device that receives submission of content (high-speed content and low-speed content) from a content submission device (not shown). This content submission acceptance device 40 not only accepts content submission, but also detects a communication bandwidth that changes over time for the content accepted, and sets the above threshold based on the communication bandwidth.

  The content database 45 is a storage device such as a hard disk device, and stores received content (high-speed content and low-speed content) and a threshold set for the high-speed content in association with each other.

Here, the low-speed content is displayed to the clients 10 ₁ to 10 _n when the environment on the client 10 ₁ to 10 _n side is for low speed or the measured communication speed is low (less than a threshold value). For example, a small-volume Internet advertisement. As described above, the low-speed content is the measurement data itself and has a capacity sufficient to obtain a highly reliable measurement result.

On the other hand, the high-speed content is distributed to the clients 10 ₁ to 10 _n when the environment on the client 10 ₁ to 10 _n side is for high speed or the measured communication speed is high (above a threshold value). For example, a large-capacity Internet advertisement. The threshold value is a threshold value set by a threshold value setting unit 46b described later.

  The control unit 46 is a control unit that controls the content submission receiving apparatus 40 as a whole, and includes a binary analysis execution unit 46a and a threshold setting unit 46b. The binary analysis execution unit 46a reads the submitted high-speed content data from the content database 45, and executes a binary analysis to calculate a communication band for each frame of the content.

  The threshold value setting unit 46b refers to the communication band calculated by the binary analysis execution unit 46a, extracts the maximum value of the communication band, and sets the extracted maximum value as the threshold value of the high-speed content. Then, the threshold value setting unit 46 b stores the high-speed content data and the threshold value in association with each other in the content database 45 and transmits them to the content distribution device 50.

  FIG. 2 is a diagram illustrating an example when the maximum value of the communication band is set as a threshold value. FIG. 2 shows a communication band that changes with time in a certain high-speed content. This communication band information is obtained when the binary analysis execution unit 46a executes binary analysis of high-speed content. Then, the threshold setting unit 46b performs processing for setting the maximum communication band value as the threshold for the high-speed content.

Returning to the description of FIG. 1, the content distribution device 50 is a device that distributes content according to the communication speed on the client 10 ₁ to 10 _n side. Actually, the content distribution device 50 is configured by a plurality of servers such as a Web server, an advertisement server, and a file server. The content distribution device 50 includes an input unit 51, a display unit 52, a storage unit 53, a communication unit 54, a content database 55, and a control unit 56.

  The input unit 51 is an input device such as a keyboard or a mouse. The display unit 52 is a display device such as an LCD or CTR. The storage unit 53 is a storage device such as a memory that stores various types of information used by the control unit 56 and the like. The communication unit 54 is connected to the network 30 and the network 60, and controls communication according to a predetermined communication protocol.

  The content database 55 is a storage device such as a hard disk device, and is set for the low-speed content 55a, the high-speed content 55b, and the high-speed content to be distributed received from the content submission receiving device 40. Threshold information 55c, which is threshold information, is stored in association with each other.

  The control unit 56 is a control unit that controls the entire content distribution device 50, and includes a communication speed measurement unit 56a and a distribution execution unit 56b.

The communication speed measuring unit 56a detects the communication speed on the communication path between the client (for example, the client 10 ₁ ) that has issued a request for content distribution among the clients 10 ₁ to 10 _n and the content distribution device 50. Specifically, the communication speed measurement unit 56a transmits low-speed content as measurement data for measuring the communication speed, and calculates the communication speed from the time required for transmission.

  The distribution execution unit 56b determines whether or not the communication speed measured by the communication speed measurement unit 56a is larger than the threshold set by the content submission receiving device 40, and the communication speed is smaller than the threshold. In this case, the low-speed content is displayed as it is on the client, and when the communication speed is higher than the threshold value, the high-speed content is distributed and displayed on the client.

  Next, a processing procedure of threshold value setting processing according to the first embodiment will be described. FIG. 3 is a flowchart of the threshold setting process according to the first embodiment.

  First, in step SA1 shown in FIG. 3, the communication unit 44 of the content submission receiving apparatus 40 receives submission of content (low-speed content and high-speed content). In step SA2, the content database 45 stores the received content.

  Thereafter, in step SA3, the binary analysis execution unit 46a reads the high-speed content stored in the content database 45 and performs binary analysis of the high-speed content.

  Specifically, the binary analysis execution unit 46a determines the type of content (video content or content created by flash, etc.), the capacity (number of bits) of each frame, the playback speed of each frame, the content distribution time, etc. Is analyzed.

  In step SA4, the binary analysis execution unit 46a calculates a communication band for each frame of content from the capacity of each frame and the playback speed of each frame, and stores the calculated communication band in the storage unit 43.

  Subsequently, in step SA5, the threshold value setting unit 46b reads the information of the communication band for each frame stored in the storage unit 43, and detects the maximum band. In step SA6, the threshold value setting unit 46b sets the detected maximum bandwidth as a threshold value.

  Subsequently, in step SA7, the threshold value setting unit 46b displays on the display unit 43 the proportion of users who can distribute the high-speed content. Specifically, the threshold setting unit 46b refers to a database (not shown) that stores the aggregate results of the line speeds of a large number of users, and calculates the percentage of users whose line speed is greater than the threshold. indicate.

  Thereafter, in step SA8, the threshold setting unit 46b transmits the data of the contents (low speed content and high speed content) and threshold information to the content distribution device 50, and the communication unit 54 of the content distribution device 50 In step SA9, the content received from the content submission receiving device 40 and threshold information are stored in the content database 55.

Next, detailed processing of the content distribution processing according to the first embodiment will be described with reference to FIGS. FIG. 4 is a flowchart (1) illustrating a processing procedure of the content distribution processing according to the first embodiment, FIG. 5 is a flowchart illustrating the client information determination processing illustrated in FIG. 4, and FIG. 3 is a flowchart (2) illustrating a processing procedure of content distribution processing according to 1. Hereinafter, the operation when the content is distributed from the content distribution device 50 to the client 10 ₁ will be described.

First, at step SB1 shown in FIG. 4, the client 10 _1, the content delivery apparatus 50 via the network 30, and transmits an HTTP request for content distribution. In step SB2, the communication speed measurement unit 56a of the content distribution device 50 sets the script in an HTML file.

In step SB3, the communication speed measurement unit 56a transmits the HTML file scripts mentioned above is set to the client 10 _1. Thus, the client 10 _1, based on the script configured in the HTML file, performing a subsequent processing step SB4, the client information determination processing in step SB9 in parallel.

In step SB4, the client 10 _1, obtains information of the start time from the timer (not shown). The start time is set as a reference time when distribution (downloading) of the low-speed content 55a from the content distribution device 50 is started.

At step SB5, the client 10 _1, the content delivery apparatus 50 requests the low-speed content.

  Thereby, in step SB6, the communication speed measuring unit 56a of the content distribution device 50 acquires the low speed content 55a from the content database 55. The low speed content 55a is used for measuring the communication speed.

In step SB8, the client 10 ₁ determines whether or not the distribution of the low speed content 55a is completed, this case, the result of determination as "No", and repeats the same determination.

On the other hand, in step SB9, the client 10 ₁ executes a client information determination process. Specifically, at step SC1 shown in FIG. 5, the client 10 ₁ obtains its client information (OS, browser, multimedia playback software version, connection environment) from the storage unit (not shown).

At step SC2, the client 10 _1, OS determines whether or not more than a predetermined version (High speed).

If the OS is less than the predetermined version (slow response), the client 10 _1, the result of determination in step SC2 as "No". At step SC5, the client 10 ₁ determines whether the distribution of the low speed content 55a is completed.

If the result of determination in step SC5 is "No", the client 10 _1, the same determination is repeated.

On the other hand, the determination in step SC2 is "Yes", i.e., if the OS is above the predetermined version (High speed), in step SC3, the client 10 _1, the browser determines whether a predetermined version or higher To do.

If the browser is less than the predetermined version (slow response), the client 10 _1, the result of determination in step SC3 is "No". At step SC5, the client 10 ₁ determines whether or not the distribution of the low speed content 55a is completed, this case, the judgment result is "Yes". In step SC6, the client 10 ₁ displays distributed low-speed content 55a on a display (not shown).

On the other hand, the determination in step SC3 is "Yes", i.e., if the browser is more than a predetermined version (High speed), at step SC4, the client 10 _1, multimedia playback software or given version (High speed) It is determined whether or not.

When the multimedia playback software is less than the predetermined version (slow response), the client 10 _1, the result of determination in step SC4 is "No". At step SC5, the client 10 ₁ determines whether or not the distribution of the low speed content 55a is completed, this case, the judgment result is "Yes". In step SC6, the client 10 ₁ displays distributed low-speed content 55a on a display (not shown).

On the other hand, when the result of determination in step SC4 is "Yes", the client 10 ₁ determines whether the distribution of the low speed content 55a is completed in step SB8 shown in Fig.

When the distribution of the low speed content 55a is completed, the client 10 _1, the result of determination in step SB8 is "Yes". In step SB10 shown in FIG. 6, the client 10 ₁ acquires information completion time from the timer (not shown). The completion time is set as a reference time at which the low-speed content 55a is distributed (downloaded) from the content distribution device 50.

In step SB11, the client 10 _1, the distribution of the low-speed content 55a via the communication path L, to calculate the communication speed of the communication path L (the measured value) from the following equation (1).

  Communication speed = (capacity of low-speed content 55a) / ((completion time-start time) -setup time) (1)

  In the equation (1), the completion time corresponds to the information on the completion time acquired in step SB10. The start time corresponds to the information on the start time acquired in step SB4. The capacity of the low speed content 55a is the capacity (K bytes) of the low speed content 55a distributed in step SB7.

  The setup time is a time from when the low-speed content 55a is requested to when distribution is actually started, and is defined by the script described above. This setup time is an actual measurement value (for example, 0.09) at a client having the best connection environment, and is a value based on a plurality of actual measurement values.

  This is because when the capacity of the low speed content 55a is small, the longer the setup time, the greater the influence on the communication speed. Therefore, in this case, the setup time is set to the minimum value in order to minimize the influence on the communication speed.

In step SB12, the client 10 _1, the communication speed calculated in step SB11 determines whether it is set greater than or equal to the threshold for high-speed content 55b corresponding to the low-speed content 55a. This threshold value is defined in the script described above.

If the judgment result of step SB12 is "No", i.e., if the communication speed is slow, at step SB13, the client 10 _1, displays the delivered of the low speed content 55a at step SB7 to display (not shown) Let

If the judgment result of the step SB12 is "Yes", i.e., if the communication speed is high, in step SB 14, the client 10 _1, the content delivery apparatus 50 requests the high-speed content.

  Thereby, in Step SB15, the distribution execution unit 56b of the content distribution device 50 acquires the high-speed content 55b from the content database 55.

In step SB16, the distribution executing unit 56b distributes the high-speed content 55b to the client 10 ₁ via the communication path L. In step SB17, the client 10 ₁ displays the distributed high-speed content 55b on a display (not shown).

  As described above, in the first embodiment, the storage unit 43 of the content submission receiving apparatus 40 stores information related to the communication band of the submitted content, and determines whether or not to distribute the content. When determining based on the magnitude relationship between the communication speed and the threshold value, the threshold value setting unit 46b sets the threshold value based on information related to the communication band stored in the storage unit 43; Therefore, the content holder's distribution policy is to dynamically determine whether to distribute content using the communication band of the content by determining whether to distribute the content based on the communication band information. To be able to be satisfied and to prevent content distribution from being interrupted even when the communication speed of the communication path is low so that the user can comfortably receive the content. It can be.

  In the first embodiment, the storage unit 43 of the content submission receiving apparatus 40 stores information related to the maximum value of the content communication band, and the threshold setting unit 46b stores the maximum stored in the storage unit 43. Since the threshold is set based on the information related to the value, the communication bandwidth of the content is maximized by determining whether to distribute the content based on the information of the maximum value of the communication bandwidth However, since it is possible to select content that is not distributed, the user can comfortably receive the content.

  In the first embodiment, the content database 55 of the content distribution device 50 stores the threshold set by the content submission receiving device 40, and the communication speed measurement unit 56a uses the communication path for distributing the content. The communication speed is measured by transmitting low-speed content having a smaller capacity than the content, and the distribution execution unit 56b transmits the content when the communication speed is equal to or higher than the stored threshold. Therefore, when the communication speed is less than the threshold value, the low-speed content can be output as it is, and the optimum content corresponding to the communication speed can be distributed without increasing unnecessary traffic volume. Can do.

  In the first embodiment, the threshold value is set for the maximum communication bandwidth of the content. However, the average value of the communication bandwidth of the content may be calculated and the value may be set as the threshold value. .

  In this case, the threshold value setting unit 46b of the content submission receiving apparatus 40 shown in FIG. 1 calculates the average value of the communication band from the information of the communication band for each frame analyzed by the binary analysis unit 46a. Set the average value as the threshold.

FIG. 7 is a diagram illustrating an example when the average value of the communication band is set as the threshold value. As shown in FIG. 7, the average value of the communication band is set as a threshold value. This method is used to send high-speed content with a large amount of information as much as possible if the communication speed on the client 10 ₁ to 10 _n side is larger than the content bandwidth on average even if the communication bandwidth is temporarily insufficient. It will be effective.

  That is, in this modification, the storage unit 43 of the content submission receiving device 40 stores information related to the average value of the communication band of content, and the threshold setting unit 46b stores the average stored in the storage unit 43. Since the threshold value is set based on the information related to the value, the communication speed of the communication path is determined by determining whether to distribute the content based on the information of the average value of the communication band. By transmitting the content when it exceeds the bandwidth on average, the criteria for transmitting the content can be relaxed and adjusted so that the content can be transmitted to the user as much as possible.

In the first embodiment, the maximum communication bandwidth of the content is set as the threshold value. However, in consideration of the measurement error of the communication speed on the client 10 ₁ to 10 _n side, a width corresponding to the measurement error is given. A threshold value may be set. Specifically, the magnitude of the measurement error is statistically obtained in advance, and the threshold value is set by adding the measurement error to the maximum value of the communication band.

  In the first embodiment, the content distribution standard is set based on the content communication band. However, the content distribution standard may be set based on the content distribution time (see FIG. 2). Good. Therefore, in the second embodiment, a case will be described in which the content distribution reference is set based on the content distribution time.
