Network data transmission system

Abstract

The invention discloses a network data transmission system, which includes a communication module and cables. The communication module is used for receiving and sending signals bearing voice service, broadcast TV service and data service. The cable is coupled to the communication module, and the cable includes at least one voice service channel for transmitting the signal carrying the voice service, and a broadcast TV channel for transmitting the signal carrying the broadcast TV service. A service channel and a data service channel for transmitting the signal carrying the data service. The network data transmission system of the present invention can realize high-definition digital TV, analog TV, computer Internet access, digital broadcasting and IP telephone communication, avoids repeated networking, saves line resources, has low manufacturing cost, strong practicability, and is easy to popularize and popularize.

Description

technical field [0001] The present invention relates to the field of network communication, and more specifically relates to a wireless transmission device that utilizes wireless broadband network technology to realize the three-network integration of a telecommunication network, a broadcast television network and a computer communication network. Background technique [0002] With the development of communication technology, telephone technology, data network technology and cable TV technology have developed quite maturely as single service technologies. [0003] For telephony technology mainly used for voice services, its network topology is as follows: figure 1 As shown, the user's telephone terminal 160 is connected to the distribution box 120 through a cable, and the distribution box 120 is connected to the telecommunications core network 110 through a cable. For ordinary telephone users, they can only receive voice signals through the telephone set and carry out voice ...

Problems solved by technology

At present, a computer can be connected through an access device such as an asymmetric digital subscriber line (Asymmetric Digital Subscriber Line, ADSL) 150, and receive data services provided by an Internet service provider (Internet Service Provider, ISP) 130, but the development of the data service requires Realized by specialized equipment, it is impossible to carry out multiple services through a common access equipment or system

[0004] For the data network technology used for data services, its network topology is as follows: figure 2 As shown, a user's data terminal, such as a computer 240, is connected to an Internet Protocol (Internet Protocol, IP) core network 210 through a dedicated hub 220. The IP core network 210 implements data service interaction through packet switching and receives data from other data terminals. Information, or business data provided by ISP230, but IP core network 210 is based on packet switching, and packet switching is a non-connection-oriented technology with low reliability. It cannot be realized for general voice services with high real-time requirements.

Although VoIP (Voice over Internet Protocol, VoIP) technology is currently implemented, VoIP also requires special access equipment (VoIP gateway) to implement
