Embodiment Construction

[0044] The core of the present invention is: applying Homeplug technology to the cable TV coaxial network, through data conversion between data based on Ethernet protocol and data based on Homeplug protocol, between data based on Homeplug protocol and radio frequency signal based on Homeplug protocol The conversion, frequency conversion modulation, equalization, and frequency conversion demodulation process of the radio frequency signal enable the device of the present invention to realize the purpose of data transmission using a coaxial cable. Furthermore, a broadband data access system for realizing data communication in a cable TV network is provided. The broadband data access system makes full use of the existing cable TV coaxial network, and realizes cable TV and broadband with a small network transformation cost. A line-to-home solution for multiple services such as data access.

[0045] The following first briefly introduces the Homeplug technology. The Homeplug technology ...

Abstract

This invention provides a device for realizing data transmission and a data access system including: applying Homeplug technology on a wire TV coaxial net, carrying out data conversion between data based on Ethernet protocol and Homeplug protocol to transmit the RF signals based on the Homeplug protocol in a coaxial cable, so that, the wire TV coaxial net can realize data access for the user end so as to provide a new method for connecting wire TV and data access to users.

Description

Technical field [0001] The present invention relates to digital television technology in the field of network communication, in particular to a data transmission device and an access system in a digital television system. Background technique [0002] In the prior art, the network diagram of the data access system that realizes data communication in HFC (Hybrid Fiber Coaxial Cable Network) is as attached figure 1 Shown. [0003] in figure 1 In HFC, the data access system for data communication mainly includes: CMTS (CableModem Termination System cable modem central office) equipment, upconverter, OSS (Operation Support System network management / operation support system) and CM (Cable Modem cable modem) ). [0004] CMTS equipment is HFC network data access central office equipment, and is the connection equipment of data network and HFC analog radio frequency network. Its main functions include: network data forwarding, protocol processing, and radio frequency modulation and dem...
