The present invention relates to a system and a method for providing a video community service based on a stream address translation apparatus. More particularly, the present invention provides a method for streaming video content in a community establishment terminal when providing a personal Internet broadcasting service. By performing only relaying, it is possible to minimize the load on the device for relaying content and to provide economical Internet broadcasting, and to allow community members to share and distribute each other's contents.

Internet broadcasting, which appears as a convergence of broadcasting and communication by the implementation of a high-speed information communication network that transmits high-capacity information in a short period of time, breaks away from the unilateral "combination" structure that appears in existing public waves or cable broadcasting. You can select a broadcast at any time to listen to or watch it through streaming technology.

Accordingly, Internet broadcasting provides not only contents of airwaves or cable broadcasting but also unique broadcasting contents related to individual's daily life, and these broadcasting contents are produced by an Internet broadcasting station server connected to the Internet and are unspecified on the Internet. Broadcast on the Internet at the request of the client.

However, unlike over-the-air broadcasting, Internet broadcasting can be viewed only when a viewer who wants to watch the broadcast or a client who wants to listen to the small Internet broadcasting station that has produced various broadcasting contents is able to watch the broadcast and more than the small internet broadcasting server system can accommodate. If a large number of clients access at the same time, there is a problem in that real-time broadcasting is difficult due to the unique characteristics of the Internet.

In addition, in the related art, since a relay apparatus including a streaming facility is very expensive, it is difficult to purchase and operate it in a small internet broadcasting station.

The peer-to-peer multicast method is a software multicast method in which each user terminal performs a role of a streaming relay device to relay content to a plurality of receiver terminals, thereby solving an expensive streaming relay device and an increase in network cost.

However, this method is a multi-stage relaying method like a tree structure. If a user terminal that normally plays a relay role terminates normally or abnormally, another terminal should replace it. Content packet loss may occur for all receiver terminals. As such, there is a problem in that image quality deteriorates when packet loss occurs.

In addition, although the conventional peer-to-peer multicast method can provide a function of exchanging opinions between viewers through comments, only one-way broadcasting comments can be provided and content exchange is difficult, thereby securing content and free video exchange among community members. There was a difficult back problem.

As described above, the real-time video community system did not exist in the prior art, and although it existed, it was limited to a one-way internet broadcasting system, and there were problems such as a limited number of viewers, lack of economic feasibility, and difficulty in securing broadcast contents.

IP address information to be provided), and provides the community member terminal 400 with the multicast IP address and port number of the community channel or the port number of the community channel. At this time, if the Internet network supports multicast, the IP address to be converted is a multicast IP address assigned to a community channel, otherwise the IP address to be converted is an IP address of the community member terminal 400.

Thereafter, the community establisher terminal 100 generates and transmits a packet including video content (real time video, pre-produced video) and an IP address of the stream address conversion apparatus 200 as a destination by using a pre-installed program ( S105, S106).

Subsequently, the stream address conversion apparatus 200 changes the destination IP address based on the IP address information table of the community channel transmitted from the video community server 500 to the video packet received from the community establisher terminal 100 (S107). ), The changed packet is sent to the community member terminal 400 (S108), and sent to the content server 300 to be stored (S109).

At this time, for example, in the address translation in the stream address translation apparatus 200, if the source IP address of the received packet is X1.X2.X3.X4, the destination IP address of the packet is changed to Y1.Y2.Y3.Y4. If it is X5.X6.X7.X8, change it to Y5.Y6.Y7.Y8. In some cases, use the port number to distinguish the destination address.

In addition, in the Internet network that supports multicast, the IP address of the community member terminal 400 is transmitted to the Internet network using the multicast IP address assigned to the community as the destination IP address, and when the multicast is not supported. It is preferable to copy the video packet to each community member terminal 400 and send it as an address.

In addition, the community member terminal 400 sends an Internet Group Management Protocol (IGMP) Join message to the Internet by using the information transmitted from the video community server 500, or a corresponding port. Open the number to receive video content.
