Description

계층적 전송을 이용한 인터넷 방송 시스템 및 인터넷 방송 방법{Internet Broadcasting System/Method Using Hierarchical Transmission}Internet Broadcasting System / Method Using Hierarchical Transmission}

본 발명은 인터넷 상에서 동영상 및 오디오 등의 각종 멀티미디어 데이터를 전송하는 인터넷 방송 방법에 관한 것으로, 특히 대용량의 전송이 필요함으로 인해 발생하는 인터넷 방송 시스템의 병목 현상을 계층적인 전송망을 이용하여 감소시킬 수 있는 인터넷 방송 방법에 관한 것이다.The present invention relates to an Internet broadcasting method for transmitting various multimedia data such as video and audio over the Internet. In particular, the bottleneck of the Internet broadcasting system caused by a large capacity transmission can be reduced by using a hierarchical transmission network. The present invention relates to an internet broadcasting method.

일반적으로 인터넷 방송은 인터넷 방송을 제공하는 중앙 집중식 서버가 멀티 미디어 데이터를 그 서버와 접속한 모든 이용자들의 단말기로 전송해 주는 방식을 사용하고 있다. 즉, 하나의 인터넷 방송을 제공하는 공급자가 운영하는 인터넷 방송 서버에 인터넷 접속이 가능한 다수의 인터넷 이용자들이 접속을 실시하여 서버에서 제공하는 방송 즉 동영상과 오디오 등 각종 멀티미디어를 전송받아 시청하게 된다. 즉, 현재까지의 인터넷 방송 방법은 대용량의 인터넷 방송 서버에 이용자 수에 관계없이 모두 중앙의 서버에 접속하도록 되어 있다.In general, Internet broadcasting uses a method in which a centralized server providing Internet broadcasting transmits multimedia data to terminals of all users connected to the server. That is, a large number of Internet users who can access the Internet connect to an Internet broadcasting server operated by a provider that provides one Internet broadcast, and receive and watch various multimedia such as video and audio provided by the server. In other words, all the Internet broadcasting methods up to now are connected to the central server regardless of the number of users.

멀티미디어 기술의 개발이 가속화됨에 따라 통신 데이터의 용량이 커져 통신의 병목현상이 빈번히 발생되거나 서버가 다운되는 원인이 되기도 한다.As the development of multimedia technology is accelerated, the volume of communication data increases, causing frequent communication bottlenecks or server downtime.

특히 상기와 같은 인터넷 방송의 경우 화질과 음질의 우수성이 경쟁력을 죄우하므로 데이터의 용량의 증가는 불가피한 상황이고, 이러한 상황에서 양질의 인터넷 방송 서비스를 제공하기 위해서는 서버의 성능 및 용량 증가가 필수 사항이다. 그러나 수 많은 인터넷 방송 이용자들의 욕구를 충족하기 쉽지않다.In particular, in the case of the above-mentioned Internet broadcasting, the superiority of the image quality and sound quality is inevitably competitive, and thus the increase of data capacity is inevitable. In such a situation, it is necessary to increase the performance and capacity of the server in order to provide high quality internet broadcasting service. . However, it is not easy to meet the needs of many Internet broadcasting users.

따라서, 아무리 성능이 우수하고 대용량의 서버이더라도 접속한 이용자가 많을 경우 차후 접속을 원하는 이용자는 접속이 아예 불가능 하거나 접속이 되더라도 데이터 전송의 속도가 느려져 양질의 방송을 시청할 수 없다는 문제점이 있었다.Therefore, even if the performance is high and a large server, if there are many users connected, there is a problem that the user who wants to connect later cannot access the high quality broadcast because the data transmission speed is slow even if the connection is not possible at all.

또한, 상기와 같은 현상이 지속적으로 발생하거나 동시에 최대 용량 이상의 이용자가 접속을 시도하게 되면 인터넷 방송을 제공하는 서버가 다운되어 서버 복구시까지 인터넷 방송을 제공하지 못한다는 문제점도 있었다.In addition, if the above phenomenon occurs continuously or at the same time when a user with a maximum capacity or more attempts to access, there is a problem that the server providing the Internet broadcast is down and cannot provide the Internet broadcast until the server recovery.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여, 서버에 접속되는 이용자들의 단말기 수를 한정하고, 한정된 수 이상의 이용자 단말기가 접속을 시도할 경우 이미 접속되어 있는 단말기들 중 어느 한 단말기로 접속을 유도하여 단말기에서 단말기로 데이터를 중계할 수 있도록 함으로써 다수의 이용자들에게 병목현상 없이 양질의 인터넷 방송을 제공하는 것을 목적으로 한다.Accordingly, in order to solve the above problems, the present invention limits the number of terminals of users connected to the server, and when more than a limited number of user terminals attempt to connect, access the terminal to any one of the terminals already connected. It aims to provide high quality internet broadcasting without bottlenecks to a large number of users by inducing and relaying data from terminal to terminal.

또한, 서버로 직접 접속되는 단말기의 수를 제한 함으로서 동시에 접속을 요청하는 이용자가 많더라도 서버의 다운없이 지속적으로 인터넷 방송을 제공할 수 있게 하는 것을 목적으로 한다.In addition, by limiting the number of terminals directly connected to the server, even if a large number of users requesting access at the same time, it is an object to enable to continuously provide the Internet broadcast without the server down.

본 발명은 상기 목적을 달성하기 위하여, 동영상 및 오디오를 인터넷을 통하여 방송하는 인터넷 방송 서버와 이용자들의 단말기로 이루어진 인터넷 방송 시스템에 있어서, 상기 인터넷 방송 서버는 접속되는 단말기의 수를 한정하고, 한정된 수 이상의 단말기가 접속을 시도할 경우 이미 접속되어 있는 단말기들 중 어느 한 단말기로 접속을 유도하고, 접속을 유도한 단말기로의 접속이 불가능할 경우 이미 접속되어 있는 다른 단말기들 중 어느 한 단말기로 접속을 유도하도록 프로그램된 인터넷 방송 서버와; 상기 서버 또는 이미 서버에 접속된 다른 단말기로 부터 방송 데이터를 전송받아 디스플레이하고, 상기 서버 또는 접속하고자 하는 단말기로부터 접속이 유도된 단말기가 접속을 요청하면 접속을 인가하여 전송되는 데이터를 접속된 단말기로 전송하고, 이미 접속된 단말기 수가 한정된 수를 초과하거나 통신 상태의 과부하가 우려되는 경우 서버 또는 접속을 유도한 단말기로 접속 불가데이터를 전송하거나 이미 접속되어 있는 단말기들 중 어느 하나로 접속을 유도하는 다수의 단말기들로 이루어진 데이터의 계층적 전송을 이용한 인터넷 방송 시스템을 특징으로 한다.In order to achieve the above object, the present invention provides an Internet broadcasting system comprising an Internet broadcasting server for broadcasting video and audio over the Internet and a terminal of users. When the above terminal tries to connect, it induces the connection to any one of the terminals which are already connected. If the connection to the terminal that induced the connection is impossible, it induces the connection to any of the other terminals that are already connected. An internet broadcast server programmed to; Receives and displays broadcast data from the server or another terminal already connected to the server, and when the terminal induced connection is requested from the server or the terminal to be connected, the terminal authorizes the connection and transmits the transmitted data to the connected terminal. If the number of terminals already connected is exceeded by a limited number or there is a concern about the overload of the communication state, a plurality of terminals that transmit unaccessible data to the server or the terminal which induced the connection or induce the connection to any of the terminals already connected. An internet broadcasting system using hierarchical transmission of data consisting of terminals is featured.

이하, 첨부된 도면을 참조로 하여 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 따른 데이터의 계층적 전송을 이용한 인터넷 방송 시스템의 전체적인 구성을 나타낸 것으로, 동영상 및 오디오와 같은 방송용 멀티미디어 데이터를 제공하는 인터넷 방송 서버(100)와, 상기 서버(100) 또는 서버에 연결된 단말기(110)에 접속하여 데이터를 전송받아 이용자가 시청할 수 있도록 하는 다수의 단말기들(110 또는 120)로 이루어져 있다.1 shows an overall configuration of an internet broadcasting system using hierarchical transmission of data according to the present invention. The Internet broadcasting server 100 provides multimedia data for broadcasting such as video and audio, and the server 100 or the server. It is composed of a plurality of terminals (110 or 120) to connect to the terminal 110 connected to receive the data for the user to watch.

본 발명의 설명을 명확하게 하기 위하여, 서버에 직접 연결되는 단말기들을 1차 접속 단말기, 1차 접속 단말기에 접속하는 단말기들을 2차 접속 단말기, …, N-1차 접속 단말기에 접속하는 단말기들을 N차 접속 단말기라 편의상 명명하기로 한다. 이때, N은 2보다 크거나 같은 임의의 정수이다.In order to clarify the description of the present invention, terminals connected directly to the server are connected to the primary access terminal, terminals connected to the primary access terminal, secondary access terminals,... For convenience, the terminals connected to the N-first access terminal will be referred to as N-th access terminal. Where N is any integer greater than or equal to 2.

먼저, 상기 서버는 멀티미디어 데이터를 제공하며, 접속되는 1차 접속 단말기의 수를 상기 데이터를 최상의 조건으로 제공할 수 있도록 한정한다. 따라서 한정된 수 이상의 단말기가 접속을 시도할 경우 접속을 차단하고 이미 접속되어 있는 1차 단말기들 중 어느 한 단말기로 접속을 유도한다. 이때, 한정된 수를 초과한 시점부터 접속을 시도하는 단말기들을 상기 1차 접속 단말기들로 고르게 분배하여 접속을 유도한다. 상기 서버에 접속된 1차 접속 단말기는 서버로부터 방송 데이터를 전송받아 이용자가 시청할 수 있도록 디스플레이하고, 서버로 부터 유도된 접속 요청 단말기들의 접속을 인가하거나 접속 불가시 이미 접속되어 있는 2차 접속 단말기들 중 어느 한 단말기로 접속을 유도한다. 이때, 상기 1차 및 2차 단말기들과 후술하는 모든 단말기들에는 서버 또는 상위 단말기에 접속하여 데이터를 수신하고 수신된 데이터를 중계하여 하위 단말기들에 전송하는 중계 기능을 가지며, 각 단말기들은 또한 데이터 수신 및 중계 전송에 의해 기능이 저하되지 않는 범위에서 접속되는 단말기들의 수를 한정한다.First, the server provides multimedia data, and limits the number of primary access terminals connected to provide the data in the best condition. Therefore, when more than a limited number of terminals attempt to connect, they block the connection and induce the connection to any one of the already connected primary terminals. At this time, the terminals attempting to connect from the time limit exceeding the limited number are evenly distributed to the primary access terminals to induce connection. The primary access terminals connected to the server receive broadcast data from the server and display them for viewing by the user, and the secondary access terminals that are already connected when the connection request terminal derived from the server is authorized or not accessible. Induces connection to either terminal. In this case, the primary and secondary terminals and all terminals to be described later have a relay function of receiving data by connecting to a server or an upper terminal and relaying the received data to lower terminals. It limits the number of terminals connected in a range in which the function is not degraded by reception and relay transmission.

상기 서버로부터 접속이 유도되어 1차 접속단말기 접속된 2차 접속 단말기는서버로부터 방송 데이터를 전송받아 이용자가 시청할 수 있도록 디스플레이하고, 1차 접속 단말기로부터 유도된 접속 요청 단말기들의 접속을 인가하거나 접속 불가시 이미 접속되어 있는 3차 접속 단말기들 중 어느 한 단말기로 접속을 유도한다.The secondary access terminal connected to the primary access terminal after the connection is induced from the server displays the broadcast data received from the server for the user to watch, and permits or cannot access the connection of the access request terminals derived from the primary access terminal. Induces a connection to any one of the tertiary access terminals already connected.

상기와 같은 과정의 반복에 의해 N-2차 접속 단말기로부터 접속이 유도되어 N-1차 접속단말기 접속된 N차 접속 단말기는 서버로부터 방송 데이터를 전송받아 이용자가 시청할 수 있도록 디스플레이하고, N-1차 접속 단말기로부터 유도된 접속 요청 단말기들의 접속을 인가하거나 접속 불가시 이미 접속되어 있는 N-2차 접속 단말기들 중 어느 한 단말기로 접속을 유도한다.By repeating the above process, the connection is induced from the N-secondary access terminal, and the N-th access terminal connected to the N- 1st access terminal receives broadcast data from the server and displays the user so that they can watch it. The connection request terminal derived from the secondary access terminal is authorized or the connection is induced to any one of the N-second access terminals that are already connected when the connection is not available.

상기와 같이 본 발명에 의한 인터넷 방송은 한정된 수 많은 접속할 수 있도록 하고, 한정된 수를 초과하는 접속 시도 단말기들은 서버 또는 단말기에서 하위 단말기들로 접속을 유도하여 항상 같은 속도로 데이터를 전송받을 수 있도록하여 서버의 용량을 크게하지 않고도 통신 부하없이 대용량의 방송 서비스가 가능하도록 한다.As described above, the Internet broadcasting according to the present invention allows a limited number of accesses, and the attempted access terminals exceeding the limited number induce a connection from the server or the terminal to the lower terminals so that data can always be transmitted at the same speed. It allows large capacity broadcasting service without communication load without increasing server capacity.

상술한 바와 같이 본 발명은 서버를 최상위로 하고 서버에 접속되는 단말기의 수를 한정하고, 한정된 수 이상의 단말기가 접속을 요청할 경우 이미 접속되어 있는 하위 단말기들 중 어느 한 단말기로 접속을 유도하여 접속되어 있는 단말기들이 데이터 전송의 중계기 역할을 하게 함으로써 서버의 용량의 증가 없이도 원하는 모든 인터넷 방송 이용자들에게 양질의 방송을 제공할 수 있다.As described above, the present invention limits the number of terminals connected to the server with the server as the highest level, and when more than a limited number of terminals request a connection, the present invention is connected by inducing a connection to any one of the lower terminals already connected. By allowing the existing terminals to act as repeaters for data transmission, it is possible to provide high quality broadcasting to all desired Internet broadcasting users without increasing the capacity of the server.

또한, 서버 또는 단말기들에 접속하는 하위 단말기들의 수를 제한함으로써, 서버나 하나의 단말기로 많은 수의 단말기가 접속되는 일이 없어 통신의 과부하에 따른 병목 현상이나 서버의 다운을 미연에 방지할 수 있다.In addition, by limiting the number of lower terminals connected to the server or terminals, a large number of terminals are not connected to the server or a single terminal, thereby preventing bottlenecks or downtime due to communication overload. have.
