Description

TECHNICAL FIELD [0001] The present invention relates to a video streaming data transmission method,

The present invention relates to a method and system for determining a video streaming data transmission method in accordance with user behavior analysis.

IP (Internet Protocol) -TV is defined as a multimedia service such as television, video, audio, document, graphic, and data services provided through an IP network with guaranteed quality, security and reliability. A live TV service, and a stored video service such as a VOD in which transmission is performed by a unicasting method.

Internet Protocol (IP) -TV services are also provided in a peer-to-peer network (P2P) manner. Peer-to-peer networks or peer-to-peer networks are networks that depend on the computation and bandwidth performance of the machines participating in the network configuration, rather than focusing on a relatively small number of servers. P2P networks are generally used when interconnecting nodes in a large ad hoc manner. These networks are useful in many ways, and sharing of arbitrary digital format files such as audio, video, and data is very common. P2P IP-TV is a method of providing IP-TV service by configuring such a network. Generally, two servers participate in the service. They are a tracker server having information on nodes participating in the service and a channel server providing broadcast channels. The node connecting to the broadcast channel first accesses the tracker server and receives the location of the data. If it is the first node that accesses the broadcast channel, it informs the channel server to receive the data directly. Then, a part of the broadcast is stored in the storage device of the node. When a new node tries to access the same channel, the tracker server informs the IP addresses of the nodes it has previously connected to. In this case, data is directly received from the nodes of the corresponding IP address and is reproduced.

IP-TV is being served through a wired network capable of high bandwidth. Routers or other devices capable of handling large amounts of data are required. Since a large amount of redundant data is transmitted through a public network, infrastructure investment should be increased. In addition, due to the characteristics of broadcasting, the number of users is explosively increased at a specific time or when an event occurs. At this time, in order to deal with the explosively increased traffic, . So, service providers have to waste a lot of resources. So the way it came to be is P2P IP-TV. Unlike the conventional method in which the server has all the data and the user sends all the information to the server, the set-top boxes have pieces of data and the pieces of data from the surrounding set- And the content is received and transmitted. Even if the user suddenly increases, there is no need for additional resources, since the nodes having data also increase together.

However, if there is a small number of users or a request for unpopular data in this P2P IP-TV service system, a considerable delay time is required, sometimes normal playback may not be possible, and there may be a problem with the service. In addition, P2P IP-TV, which is currently being commercialized, is provided in the form of a PC application, and most of them are used free of charge, which is a problem in that it is vulnerable to copyright protection and security.

Korean Patent Application No. 10-1040312 discloses a method of transmitting P2P data to an IPTV that transmits data using a conventional client server method. When a user desires to receive data desired by another user equally, And also describes how to receive data from the network. However, when determining the path, only the data transmission path determination method considering only the optimum path of the data, not the behavior analysis data of the user, is described.

The present invention provides a method and system for determining a method of transmitting video streaming data based on a behavioral analysis of a service user on a service for streaming video content.

According to an aspect of the present invention, there is provided a method for determining a video streaming data transmission method according to an embodiment of the present invention, the method comprising: requesting a video provider to open a channel for providing a new video service; Calling the channel stability indicator value of the channel delimiter in the channel stability index database; checking whether the channel stability indicator value of the channel delimiter is stored in the channel stability index database; Comparing the channel stability indicator value with a predetermined threshold value, and transmitting the new video service according to a predetermined transmission scheme according to the comparison result.

Wherein the step of verifying whether the channel stability indicator value of the channel identifier is stored in the channel stability index database includes: when the channel stability indicator value of the channel identifier is stored in the channel stability indicator database, And setting a channel stability indicator value of the channel identifier based on a predetermined channel stability indicator value when the channel stability indicator value is not stored in the channel stability indicator database.

Wherein the step of transmitting the new video service in a predetermined transmission scheme according to a result of the comparison comprises transmitting the new video service in a first transmission scheme when the channel stability indicator value is equal to or greater than a predetermined threshold value, If the channel stability indicator value is less than a predetermined threshold, the new video service may be transmitted in a second transmission scheme.

The first transmission method is a client server method, the second transmission method is a P2P method, and a new transmission method can be added.

The channel delimiter may be generated using information including the video provider's ID and video category.

Wherein the step of calling the channel stability indicator value of the channel delimiter into the channel stability index database comprises setting the channel stability indicator value, and further comprising the steps of: measuring a channel entry time and a termination time of use of the channel, Measuring a channel viewing time of a user, measuring a screening time of the channel when the channel ends, measuring a standardized channel viewing time using a channel viewing time of the user and a screening time of the channel, And setting a channel stability indicator using the normalized channel viewing time and storing the indicator in the channel stability indicator database.

According to another aspect of the present invention, there is provided a system for determining a video streaming data transmission scheme according to an embodiment of the present invention, comprising: a channel delimiter of a channel to be opened; a channel stability indicator of the channel delimiter; A channel stability indicator for storing the channel stability indicator value in a database and calling the channel stability indicator value to a channel stability index database to compare the channel stability indicator value stored in the channel stability indicator database with a predetermined threshold; A channel stability index database for storing a stability index value, and a video transmission scheme determination unit for determining a transmission scheme for transmitting the new video service according to the comparison result.

Wherein the channel stability index measurement unit checks whether the channel stability index value is stored in the channel stability index database when the channel stability index value is called in the channel stability index database, Wherein the channel stability indicator value is set based on the channel stability indicator value when the channel stability indicator value is stored in the stability indicator database and when the channel stability indicator value of the channel identifier is not stored in the channel stability indicator database, Can be set.

Existing systems can only transmit streaming data of video contents in one of the P2P method or the client server method. However, the proposed system can analyze the behavior of different users for each video content and determine the streaming data transmission method optimized for user behavior. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a method of determining a video streaming data transmission method according to an embodiment of the present invention.

A method for determining a video streaming data transmission method according to a user behavior analysis includes a step 110 of requesting a video provider to open a channel for providing a new video service, a step 120 of identifying a channel delimiter of the channel to be opened, A step 130 of calling the channel stability indicator value of the channel delimiter to the channel stability index database, a step 140 of checking if the channel stability indicator value of the channel delimiter is stored in the channel stability index database, (150) comparing the channel stability indicator value stored in the channel stability indicator with a predetermined threshold value, and transmitting the new video service in a predetermined transmission scheme according to the comparison result (151, 152) .

At step 110, the video provider may request the creation of a channel for servicing new video. In other words, if the video provider wishes to serve a new video, the server is requested to establish a channel, and the algorithm is started in the video transmission method determination section.

In step 120, the channel identifier of the channel to be opened can be confirmed. When the algorithm starts, first check the channel delimiter of the channel to be opened. The identifier of such a channel may be generated using information including a video provider's ID and a video category.

In step 130, the channel stability indicator value of the channel identifier may be called into the channel stability indicator database.

The step of calling the channel stability indicator value of the channel identifier in the channel stability indicator database may include setting the channel stability indicator value.

Measuring a user's channel viewing time by measuring a channel entry time and a leaving time of the user entering the channel; measuring a screening time of the channel when the channel is terminated; Measuring the standardized channel viewing time using the time and the running time of the channel, and setting the channel stability indicator using the standardized channel viewing time and storing the indicator in the channel stability indicator database.

More specifically, the channel stability indicator is generated for each channel, and the channel viewing time tij of the user j is measured by measuring when the user connected to the channel i has entered the channel and when the user has left the channel. The channel stability indicator measurement unit measures the channel presentation time Ti when channel i is terminated, measures the standardized channel viewing time through τj = tij / Ti, and calculates P (τij = α) P (τij <β), which is the user's distribution value, is measured by Ai and Bi.

At this time, the reference values? And? Can be empirically determined, or can be set to constant values, and the same values can be set. α is empirically users who watched α or more, and assumes that video is streamed by P2P transmission method, α value is defined when loss of streaming data is small and transmission delay is less than a certain level.

β is empirically viewed by users with less than β, it is possible to define β value when the streaming data is lost and the transmission delay is more than a certain level, assuming that the video is streamed by the P2P transmission method. The channel stability indicator measures the channel stability index (CSI) using the measured Ai and Bi values. The equation for calculating the channel stability index (CSI) is shown in Equation 1 below.

Figure 112015042912705-pat00001

When the channel stability index is obtained, the channel stability index measurement unit stores the channel stability index in the channel stability index database. The channel stability index database stores the n most recent channel stability indexes for each channel separator. If n is full, the oldest channel stability indexes are discarded and the new channel stability indexes are stored. It also stores the average of the n most recent channel stability indices. The average of the n most recent channel stability indices is calculated by the channel stability index measurement unit by calling the latest n channel stability indices in the channel stability index database and storing the average in the channel stability index database again.

After the channel is terminated, when the video provider attempts to serve the video of the same channel delimiter, the video transmission mode determination unit operates to determine how to transmit the video.

In step 140, it is possible to check whether the channel stability indicator value of the channel identifier is stored in the channel stability indicator database.

Wherein the step of verifying whether the channel stability indicator value of the channel identifier is stored in the channel stability index database includes the step of, when the channel stability indicator value of the channel identifier is stored in the channel stability index database, And setting a channel stability indicator value of the channel identifier based on a predetermined channel stability indicator value when the channel stability indicator value is not stored in the channel stability indicator database. In other words, after checking whether the channel stability index value is present in the channel stability index database, the channel stability index value (CSI: Channel Stability Index), which is a predetermined fixed value, is set based on the channel stability index value. For example, the channel stability index (CSI), which is a predetermined fixed value (default), can be arbitrarily set by a service provider from a value between 0 and 1

On the other hand, if there is a channel stability index value in the channel stability index database, it is set based on the channel stability index (CSI) stored in the channel stability index database.

In step 150, the channel stability index value (CSI) stored in the channel stability index database may be compared with a predetermined threshold value.

The new video service can be transmitted according to a predetermined transmission method according to the comparison result. (151) the new video service in a first transmission scheme when the channel stability indicator value is greater than or equal to a predetermined threshold value, and if the channel stability indicator value is less than a predetermined threshold value, (152) the new video service.

For example, the first transmission method may be a client server method, and the second transmission method may be a P2P method. In addition to the first transmission method and the second transmission method, a new transmission method can be added. If an additional transmission scheme occurs, a plurality of transmission schemes can be applied by inserting a further determiner in step 150. [ The threshold may be set to any value between 0 and 1 by the service provider.

2 is a block diagram of a system for determining a video streaming data transmission method according to an embodiment of the present invention.

The video streaming data transmission system determination system 200 according to the present embodiment may include a processor 210, a bus 220, a network interface 230, a memory 240, and a channel stability index database 250. The memory 240 may include an operating system 241 and a video transmission method routine 242. The processor 210 may include a channel stability indicator measurement unit 211 and a video transmission mode determination unit 212. In other embodiments, the video streaming data transmission scheme determination system 200 may include more components than the components of FIG. However, there is no need to clearly illustrate most prior art components. For example, the video streaming data transmission mode determination system 200 may include other components such as a display or a transceiver.

The memory 240 may be a computer-readable recording medium and may include a permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), and a disk drive. In addition, the memory 240 may store program codes for the operating system 241 and the video transmission method routine 242. These software components may be loaded from a computer readable recording medium separate from the memory 240 using a drive mechanism (not shown). Such a computer-readable recording medium may include a computer-readable recording medium (not shown) such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, or a memory card. In other embodiments, the software components may be loaded into the memory 240 via the network interface 230 rather than from a computer readable recording medium.

The bus 220 may enable communication and data transfer between components of the video streaming data transmission scheme determination system 200. [ The bus 220 may be configured using a high-speed serial bus, a parallel bus, a Storage Area Network (SAN), and / or other suitable communication technology.

Network interface 230 may be a computer hardware component for connecting video streaming data transfer mode determination system 200 to a computer network. The network interface 230 may connect the video streaming data transmission mode determination system 200 to a computer network via a wireless or wired connection.

The channel stability index database 250 may store the channel stability index measured by the channel stability index measurer 211.

The channel stability index database 250 may store and maintain all information necessary for determining a video streaming data transmission scheme according to user behavior analysis. 2, the channel stability index database 250 is constructed and included in the video streaming data transmission mode determination system 200. However, the present invention is not limited thereto and may be omitted depending on the system implementation method or environment, It is also possible that all or some of the databases exist as external databases built on separate, separate systems.

The processor 210 may be configured to process instructions of a computer program by performing input / output operations of a basic arithmetic, logic, and video streaming data transfer scheme determination system 200. The instructions may be provided by the memory 240 or the network interface 230 and to the processor 210 via the bus 220. The processor 210 may be configured to execute the program code for the channel stability indicator measurement unit 211, the video transmission mode determination unit 212, and the like. Such program code may be stored in a recording device such as memory 240. [

The channel stability indicator measurement unit 211 and the video transmission mode determination unit 212 may be configured to perform the steps 110 to 150 of FIG.

The video streaming data transmission mode determination system 200 may include a channel stability indicator measurement unit 211 and a video transmission mode determination unit 212.

The channel stability index measurement unit 211 may identify a channel delimiter of a channel to be opened, measure the channel stability index value of the channel delimiter, and store the channel stability index value in a channel stability index database. The channel stability index value may be called to the channel stability index database to compare the channel stability index value stored in the channel stability index database with a predetermined threshold value.

The channel stability index measurement unit 211 can check whether the channel stability index value is stored in the channel stability index database when the channel stability index value is called into the channel stability index database.

Wherein the step of verifying whether the channel stability indicator value of the channel identifier is stored in the channel stability index database includes the step of, when the channel stability indicator value of the channel identifier is stored in the channel stability index database, And setting a channel stability indicator value of the channel identifier based on a predetermined channel stability indicator value when the channel stability indicator value is not stored in the channel stability indicator database. In other words, after checking whether the channel stability index value is present in the channel stability index database, the channel stability index value (CSI: Channel Stability Index), which is a predetermined fixed value, is set based on the channel stability index value. For example, the channel stability index (CSI), which is a predetermined fixed value (default), can be arbitrarily set by a service provider from a value between 0 and 1

On the other hand, if there is a channel stability index value in the channel stability index database, it is set based on the channel stability index (CSI) stored in the channel stability index database.

When the channel stability indicator value of the channel identifier is stored in the channel stability indicator database, the channel stability indicator value is set based on the channel stability indicator value. On the other hand, when the channel stability indicator value of the channel identifier is not stored in the channel stability indicator database, the channel stability indicator value is set based on a predetermined channel stability indicator value.

In addition, the channel stability indicator 211 measures the channel viewing time of the user by measuring the channel entry time and the exit time of the usage that has entered the channel, and measures the display time of the channel when the channel ends. The standardized channel viewing time is measured using the channel viewing time of the user and the screening time of the channel, and the channel stability indicator is set using the standardized channel viewing time.

More specifically, the channel stability indicator is generated for each channel, and the channel viewing time tij of the user j is measured by measuring when the user connected to the channel i has entered the channel and when the user has left the channel. The channel stability indicator measurement unit measures the channel presentation time Ti when the channel i ends and measures the standardized channel viewing time through τij = tij / Ti. The user distribution value P (τij = α) above the reference value α and the reference value β P (τij <β), which is the user's distribution value, is measured by Ai and Bi. At this time, the reference values? And? Can be empirically determined, or can be set to constant values, and the same values can be set. α is empirically users who watched α or more, and assumes that video is streamed by P2P transmission method, α value is defined when loss of streaming data is small and transmission delay is less than a certain level.

β is empirically viewed by users with less than β, it is possible to define β value when the streaming data is lost and the transmission delay is more than a certain level, assuming that the video is streamed by the P2P transmission method. The channel stability indicator measures the channel stability index (CSI) using the measured Ai and Bi values. The equation for calculating the channel stability index (CSI) is shown in Equation (1).

When the channel stability index is obtained, the channel stability index measurement unit stores the channel stability index in the channel stability index database. The channel stability index database stores the n most recent channel stability indexes for each channel separator. If n is full, the oldest channel stability indexes are discarded and the new channel stability indexes are stored. It also stores the average of the n most recent channel stability indices. The average of the n most recent channel stability indices is calculated by the channel stability index measurement unit by calling the latest n channel stability indices in the channel stability index database and storing the average in the channel stability index database again.

The video transmission scheme determination unit 212 may determine a transmission scheme for transmitting the new video service according to the comparison result of the channel stability index measurement unit 211.

The video transmission scheme determination unit 212 transmits the new video service in a first transmission scheme when the channel stability indicator value is equal to or greater than a predetermined threshold value and the channel stability indicator value is less than a predetermined threshold value , The new video service is transmitted in the second transmission mode.

For example, the first transmission method may be a client server method, and the second transmission method may be a P2P method. In addition to the first transmission method and the second transmission method, a new transmission method can be added. If an additional transmission scheme occurs, a plurality of transmission schemes can be applied by inserting a further determiner in step 150. [ The threshold may be set to any value between 0 and 1 by the service provider.

3 is a diagram illustrating a video streaming data transmission method according to an embodiment of the present invention.

For example, the video provider 1 311 and the video provider 2 312 upload the video to be provided to the server 320 of the service in real time or VoD format. The server 320 generates a video streaming channel 321 or 322 for the video provided by the video provider 1 311 and the video provider 2 312 to provide a video streaming service to the users.

The delimiter of the video streaming channel 321 or 322 may be generated using the ID of the video provider and the category of the video.

For example, video user 1 (331) and video user 2 (332) show an example of streaming video of a video streaming channel 321 using a client server method, and video user 3 333, video user 4 The video user 5 335, and the video user 6 336 stream the video of the video streaming channel 322 using the P2P method.

4 is a diagram for explaining a method of determining a video streaming data transmission method when a channel is opened before a channel is opened according to an embodiment of the present invention.

Assume a service in which video provider 1 410 uploads its image to server 420 and users select and view the image. Each channel is divided into contents of drama, soccer, baseball, etc. and the ID of the video provider. For example, a soccer channel broadcasted by ID 'Hong Kil Dong' is divided into [Hong Kil Dong - football] on a server 420 providing a service.

Video provider 1 410 and Hong Kil-dong send a request for opening a soccer channel 411 to the server 420, the channel stability indicator measurement unit measures the time and the time that each user enters the channel on the soccer channel broadcast by Hong Kil Dong .

When Hong Kil-dong ends the soccer broadcast, the channel stability indicator measures the total channel display time, standardizes the channel viewing time of each user as the channel display time, and sets the reference value to 0.5 to select a person who watches more than the reference value, , The ratio of the number of viewers to the total number of viewers is measured and the channel stability index is calculated based on the measured values.

Then, the measured ratio is stored in the [Hong Kil-Dong-soccer] of the channel stability index DB 430, and the latest n ratio is received from the DB, and the channel stability index of the [Hong Kil-Dong-

When Hong Gil-dong reopens the [Hong Gil-Dong-Soccer] channel, the video image transmission method determination unit 421 executes the channel determination table to send a channel stability index request 422 to the channel stability index DB 430, (431) a channel stability index for the &quot; Hong Gil-dong - Soccer &quot;

Then, the channel stability index is compared with a threshold value, and when the comparison result is less than the reference value, the video transmission method is determined by the client server method (first transmission method) (423). Thereafter, the channel establishment 424 is performed and the establishment of the channel in the client server mode can be announced 425. Then, the image is provided to the user in a client server system (first transmission system).

On the other hand, when the comparison result is equal to or higher than the reference value, the video transmission method can be determined by the P2P method (second transmission method). Thereafter, the channel establishment can be performed and the establishment of the channel establishment in the P2P method can be announced. Then, the image is provided to the user in the client server system (second transmission system).

If the channel stability index is high, it means that many users see the time more than a certain period of time. Therefore, even if the image is provided through the transmission method close to the P2P method, the stable network can be maintained. This allows high quality video to be sent to all users while reducing traffic load to the server.

5 is a diagram for explaining a method of determining a video streaming data transmission method when a channel is not opened before a channel is opened according to an embodiment of the present invention.

Assume that the video provider 2 510 uploads its image to the server 520 and the users select and view the image. Each channel is divided into contents of drama, soccer, baseball, etc. and the ID of the video provider. For example, the soccer channel broadcasted by the user 'Hong Gil Dong' is classified into [Hong Gil Dong - Football] on the server 520 providing the service.

Video provider 2 510 and Hong Gil Dong send a request for opening a soccer channel 511 to the server 520, the channel stability indicator measuring unit measures the time and the time that each user enters the channel on the soccer channel broadcast by Hong Kil Dong .

When Hong Kil-dong ends the soccer broadcast, the channel stability indicator measures the total channel display time, standardizes the channel viewing time of each user as the channel display time, and sets the reference value to 0.5 to select a person who watches more than the reference value, , The ratio of the number of viewers to the total number of viewers is measured and the channel stability index is calculated based on the measured values.

Then, the measured ratio is stored in [Hong Kil-Dong - Soccer] of the channel stability index DB 530, and the channel stability index of [Hong Kil-dong - soccer] is obtained using the average of the latest n ratios received from the DB

When Hong Gil-dong reopens the [Hong Gil-dong-Soccer] channel, the video video transmission mode determination unit executes 521 and sends a channel stability index request 522 to the channel stability index DB 530. In channel stability index DB 530, (531) that there is no channel stability indicator for '

Then, the video transmission mode is determined as a fixed value and a default mode (523). Thereafter, the channel establishment 524 is performed and the establishment of the channel establishment in the default mode can be announced (525). Then, the image is provided to the user in a default manner.
