Description

PC advertising system using multicast group and method thereof {Real time video advertising system with Multicast Group and Method}

The present invention relates to a PC advertising system and method using the Internet, and more particularly to a PC advertising system and method for enabling the advertisement video to be played on the user computer through a multicast group.

Unlike in the early days of the Internet service, the form of the information exchanged is changed from simply character-oriented data to multimedia data. Accordingly, the streaming service technology is being developed so that large files such as video can be transmitted in real time.

Streaming technology refers to a technology that can process data as if it were a constant, continuous stream of water, which allows the browser on the user's computer to display the data on the monitor even before all the files have been transferred. A representative example of such a streaming technology is Internet broadcasting.

However, the current streaming service technology is using a unicast method, which does not satisfy the service quality for users who want high-quality video and sound at the TV level. This is a problem that arises from the current technology level and the number of concurrent users to the site that provides the video, which proves that there are a lot of video service consumers.

1A shows a unicast scheme, which is a conventional stream data transmission scheme.

Unicast method is a method in which there is only one sender (T1) and one receiver (R1) in each of the two network groups, as shown in the figure, if there are 100 recipients, there should be 100 senders. This means that as many senders T1 as the number of receivers (R1) that want to receive separately transmit the same data separately, if a unicast connection is made, there is a problem in that unnecessary duplication of transmission results in waste of resources. In addition, since a lot of load is generated in the system, the transmission speed is slowed down, which causes a break in the video.

As a solution of this unicast scheme, the broadcast scheme shown in FIG. 1B may be used. In the broadcast method, all packets are transmitted only once from the transmitter T2, and all receivers R2 to R6 receive the broadcast packets. This is a problem if only some receivers want to receive the broadcast packet. In addition, the broadcast method can broadcast only in a single internal network, so if the receiver exists in an external network that can be reached through several routers, it cannot deliver data requested from the receiver of the external network.

In addition to the problem of the transmission method as described above, another problem is that the receiver cannot perform multi tasking supported by an operating system (OS) of the computer when receiving the video data. This uses too many resources to receive and play back video stream data, making it difficult to perform other tasks simultaneously without a computer with high performance and high bandwidth specifications.

Therefore, in order to efficiently process a large amount of multimedia information such as video, a high-speed network base capable of performing a streaming service properly should be provided. However, the current unicast-based network has some limitations to accommodate multimedia data. There is a need for a network having a new infrastructure capable of multicast as shown in Figure 1c.

1C shows a multicast scheme.

As shown in the figure, the multicast scheme is similar to broadcast in that a packet is transmitted only once from the sender T3 and the receivers R7 to R9 in the network read the broadcast data packet. However, it is distinguished from broadcast that broadcast packets are selectively transmitted to receivers R7 to R9 and data can be delivered to receivers of external networks.

In order to support such multicast transmission, minimize bandwidth waste due to redundant transmission of data, and effectively guarantee various collaboration and group communication, a multicast backbone (hereinafter referred to as 'MBone') is called. Network infrastructure has been developed.

MBone is a virtual Internet backbone for IP multicast (hereinafter referred to as "IP" multicast), which is a subset of the Internet that consists of connecting hosts and routers that support multicasting.

2 is a block diagram of a multicast network using MBone.

Referring to the figure, the configuration of a multicast network shows a host that supports multicasting and multicasting routers for each region grouped by user computers. Each multicasting router and host are connected by the structure of MBone.

In the above structure, the host transmits data to each multicasting router, and each multicasting router copies data to be transmitted as many as the number of user computers requesting data, and transmits the data to each user computer requesting data transmission. That is, multicasting to the computers that requested the data.

In this way, multicasting using MBone prevents unnecessary redundant transmission and prevents waste of network resources and increases network efficiency by reducing load on the system or line. Accordingly, various Internet service applications are possible, and one of them is to smoothly stream video and sound.

An object of the present invention is to provide a PC advertisement system and a method for allowing advertisement video data to be multicasted to a user's computer without increasing the amount of data within a transmission bandwidth provided through a multicast backbone enabling the application of various Internet services as described above. To provide.

In addition, in order to enhance the effect of the advertisement to provide a user-specific advertising according to the preferences.

The method may further include processing specific information to be cast to a casting group, so that specific information may be delivered to a specific specific IP address.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is a network diagram of a PC advertisement system using a multicast group according to the present invention. In this case, each group network has the same components, and thus, one group network is represented by a representative code, and in description, the same will be described as a representative code.

Referring to the drawing, in the PC advertising system, the main server 100 as the video advertisement server and the first to fourth multicast groups MG1 to MG4 are connected through the multicast backbone, respectively. In addition, each multicast group MG1 to MG4 includes a multicasting layer 200, a subserver 300, and user computers a, b, c, and d. Here, each of the user computers a, b, c, and d are grouped and connected to one multicasting layer 200, and each multicasting layer 200 is connected to one subserver 300. In addition, the multicasting layer 200 is connected to the main server 100.

With the above configuration, the main server 100 transmits video data to each multicasting group MG1 to MG4. Then, each multicasting layer 200 copies the video packets to be delivered as many as the number of user computers requesting the video data among the computers (a, b, c, d) connected to the lower part thereof. It then multicasts the video data to each computer that requested the video by referring to its own look-up table. At this time, the sub-server 300 is multicasting in conjunction with the main server 100. That is, the video packet transmitted from the main server 100 is received and properly transmitted to the multicasting layer 200. In addition, the main server 100 and the video advertising interchange and the user information database interchange. Here, the software provided in advance is installed in the user computer that has requested the video data, and the main server 100 may exchange information with the user computer by driving the preinstalled software.

In other words, the software provided in advance so as to be installed on the user's computer can transmit the system status and selection information to the sub server 300, and the video is played in a new window on a part of the full screen with respect to the received video stream data. To be possible. The video window can also be located on the TOP than any other work window open within the screen. In addition, if a user does not receive a certain time signal from the user, the video window is enlarged step by step according to the set contents to advertise the full screen, and if any key is operated or the mouse is moved back to its original size. 4A, 4B, and 4C respectively show enlarged displays on a screen according to contents set by software provided in advance.

5 is a block diagram of the main server shown in FIG.

Referring to the drawings, the main server is a web server 10, a media server 20, an advertisement control server 30, a file transfer protocol (hereinafter referred to as FTP) server 40, and a mail server 50. And first and second databases 60 and 70 and an IP address input unit 80.

Web server 10 is responsible for content services, such as guides for advertising videos, software download guides, and orders from companies that want to advertise, it is possible to send and receive data to and from the user computer through a multicasting layer. The media server 20 processes the video data to be multicasted to the user computer when the video request signal through the multicasting group is received from the user computer through the web server 10. The advertisement control server 30 processes specific video data to be transmitted to user computers having specific IP addresses specified through the IP address input unit 80. The FTP server 40 is in charge of data transfer processing in accordance with a protocol for transferring files. The mail server 50 is in charge of processing e-mails transmitted and received. The first database 60 stores video data for each company, link domains, Internet IP addresses, contacts, locations, advertisement texts, and the like. 6A shows the contents constructed in the first database 60. In addition, in the second database 70, user preference analysis contents collected through the sub-server are built. The construction of the second database 70 is shown in FIG. 6B. In particular, it is possible to make a personalized advertisement to the user based on the contents built in the second database (70).

Referring to the operation of the main server as described above with reference to the flow chart of FIG.

First, the advertisement control server 30 may transmit specific video data to one or more specific IP addresses designated through the IP address input unit 80 (S1). That is, when a command to transmit specific video data is input to user computers having the specified IP address (S1-1), the video data is transmitted to the corresponding multicasting group so that the video data can be multicasted to the designated IP address (S1-). 2) In other words, video ads that match the preferences are sent to users with similar preferences.

On the other hand, when a system start signal transmitted from a user computer by pre-provided software installed in the user computer is received through the web server 10 (S2), the media server 20 recognizes the IP address of the user computer from the start signal. In operation S3, the video data is transmitted to the corresponding multicast group based on the IP address determined by the media server 20 (S4). If video data is already transmitted to the corresponding multicast group, the video packet is transmitted with the requested IP address. While the transmitted video stream data is being played on the user's computer, when the user clicks on the video screen and receives a signal requesting detailed information through the web server 10 (S5), the homepage of the company that requested the video advertisement to be played is displayed. Process (S6) to be linked to the computer screen. If there is no corresponding homepage (S6-2-1) while linking the homepage of the advertisement requesting company (S6-1), the advertisement text of the prepared company may be transmitted to the user's computer (S6-2-3). Process. For example, contacts or addresses can be displayed in the video window. In addition, if a link error occurs in the above-mentioned homepage link processing (S6-1) (S-6-2-2), similarly, advertisements of companies prepared in advance may be transmitted to the user's computer (S-6-2-3). do. Here, the process of linking may be performed by including the link homepage data in the video data and transmitting the link homepage. If it is determined that the user clicks the video screen by the software provided in advance, the link may be directly linked to the homepage.

Meanwhile, the local advertisement may be provided by including the region information of a specific region in the multicast video packet for advertisement. This is configured to display information on nearby restaurants, office sales outlets, supermarkets, gas stations, etc. in a specific area in a location different from the video screen on the screen. If there are several companies, list them first.

In addition, it is possible to include a variety of product information in the multi-cast video data packet advertising. In this case, an icon is automatically created next to the start button of the window screen when the system is started by the provided software, and when the user selects the icon, product information can be provided in a directory form by dividing the category. Make sure In this case, the final display of the directory becomes a product, and when a product is selected, detailed information about the corresponding homepage or the product may be transmitted.
