By the way, the conventional Internet service system configured as described above is pursuing high speed and high quality data transmission function through various subscriber networks, but the number of Internet service subscribers is exploding based on the broadband transmission characteristics up to 10Mbps. The sudden increase in traffic causes traffic congestion on the Internet, which lowers the transmission speed and has a problem in that a large data transmission service such as a video service cannot be smoothly provided to a user or a subscriber.

In particular, in the case of Internet service using HFC network, despite the broadband transmission characteristics of HFC network, it has difficulty in high-speed data transmission due to the congestion of traffic generated inside the Internet. There were problems such as receiving.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a video-based high-speed Internet data service system capable of smoothly receiving a high-speed video Internet service.

Another object of the present invention is to provide the Internet subscribers through the high-speed transmission characteristics of the video-based Education Service On Demand, Home Shopping, Movie Service On Demand, Music Service On Demand, On-demand It is to provide a video-based high speed internet data service system that can receive various services such as news on demand.

Another object of the present invention is to provide a video-based high-speed Internet data service system that can be leased line and equipment of the CMTS network to provide a variety of high-quality video services to the Internet data service provider.

In order to achieve the above object, the present invention is to extract the Internet signal of the entire signal band for the HFC network constituting the cable modem and subscriber network receiving the Internet service and the user group management, routing, security and network management; At the same time, the first to third CMTS that receives the signal of the HFC network and separates the band of the Internet signal and CATV signal to the Gigabit Ethernet switch, and the Internet output from the first gigabit Ethernet switch of the first to third CMTS CMTS network formed by connecting the first to the third Gigabit Ethernet switch and the first to the third CMTS, respectively, to transmit the data signal having the bands separated from the signal and the CATV signal to the Internet service provider at the gigabit speed. It is characterized by being configured.

Hereinafter, a video-based high-speed Internet data service system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic system block diagram of a video-based high speed data service system in an HFC network according to an embodiment of the present invention.

As shown in FIG. 2, the video-based Internet data service system according to an embodiment of the present invention has cable modems 10a, 20a, n0a of subscribers 10.20,. Is connected to the first to third CMTS (50, 60, 70) for extracting the Internet signal of the entire signal band for user group management, routing, security and network management through the HFC network 40 constituting the subscriber network, respectively It is.

At the output terminal of the HFC network 40, first to third CMTSs 50, 60 and 70 separating the bands of the signals input from the subscribers 10.20,... The first to third CMTSs 50, 60, and 70 are connected to the first to third Gigabit Ethernet switches 50a, 60a, and 70a through optical cables, and the first to third CMTSs 50, 60, and 70a. The first to third Gigabit Ethernet switches 50a, 60a, and 70a transmit optical data to the Internet service provider 30 at a gigabit speed at a gigabit speed. It is connected to each other via (62) to form a CMTS network (100).

Next, the operation and effects of the video-based Internet data service system according to the embodiment of the present invention configured as described above will be described.

Internet signals inputted by subscribers 10, 20, ... n0 from their personal computers are transmitted through the cable modems 10, 20, n0a and HFC network 40, and the CMTS 50, 60, respectively. In step 70, the CATV signal and the band are separated, multiplexed, and transmitted to the CMTS network 100 through the ports of the gigabit Ethernet switches 50a, 60a, and 70a, and are connected to the CMTS network 100. It is directly connected to the Internet server 30a of 30. Through this method, communication between the server 30a of the Internet service provider 30 and the subscribers 10, 20, ..., n0 is directly connected to the server 30a connected to the CMTS network 100 without going through the Internet. Since communication is performed, data is exchanged at high speed without being affected by the speed drop caused by the data congestion of the external Internet network.

Therefore, the video-based Internet data service system of the present invention is the Internet service provider 30 from a plurality of subscribers without going through the connection section of the CMTS 50 and the Internet service provider 30 or the bottleneck within the Internet where the bottleneck occurs By directly connecting the server 30a of the server through the CMTS network 100, the HFC network can not only activate high-speed Internet services such as various video-based on-demand services, but also activate the home shopping-related e-commerce sector. In addition, the multimedia industry related to the development of video contents can be activated, and the receiving time and transmission time of the Internet data is shortened in the subscriber or user side, so that the user's work, education, shopping, etc. increases the user efficiency. Receive higher quality service and make your internet life even more It can, and can also improve the quality of service.

In the above description, the topology of the CMTS network 100 connecting the CMTSs 50 has been described as an example of being connected in a delta type, but may be connected to any one selected from a ring type, a bus type, a star type, and a tree type. Of course it becomes.

In addition, the present invention is to reduce the speed of the CMTS network 100 to less than gigabit or use a coaxial line, or to connect the CMTS network 100 ATM (ASYNCHRONOUS Transfer Mode), Frame Relay (Frame Relay) transmission Even if various wired and wireless networks are used, such as a transmission scheme for varying the length of data), a FDDI (Fiber Distributed Data Interface; a ring structure transmission scheme using a token ring protocol), and a dedicated network, the concept of the present invention is, of course, included. to be.

In addition, the present invention is included in the concept of the present invention even if there is another device in the middle of connecting the CMTS network 100 and the server 30a, and the optical port of the CMTS (50, 60, 70) itself without using a switch Connecting CMTS (50, 60, 70) by using is also included in the concept of the present invention.

In addition, the present invention is included in the concept of the present invention when the service method uses the system configuration even when the data is not a moving picture.

In addition, the present invention is included in the concept of the invention when using the system configuration even if the service is an Internet service, not home shopping, on-demand education.

As described above, according to the video-based internet data service system of the present invention, since subscribers or users can receive internet data at high speed through a high-speed CMTS network connecting CMTSs, various video-based on-demand types using HFC networks can be used. It can not only activate high-speed Internet services such as services, but also activate the e-commerce sector related to home shopping, and activate the multimedia industry related to the development of video contents. This shortening of the user's work, education, shopping, etc. increases the efficiency of use, improving user satisfaction, receiving higher quality service, making the Internet more convenient, and improving the service quality. have.
