Method and apparatus for IP data transmission using legacy transmission system and broadband downstream transmission system in HFC network

摘要

Provided is an IP data transmission apparatus using a legacy transmission system and a broadband downstream transmission system in a HFC network. The IP data transmission apparatus includes: an headend unit for receiving data from an application server system that is a service providing apparatus, splitting the received data into general user data and management message, determining whether the general user is transmitted using a broadband or an existing service band, and transmitting the general user data through the HFC network; and a user cable terminal unit for receiving the split data transmitted from the headend unit through the HFC network, transmitting the received data to an IP based user device, and transferring the management message to the IP based user device through the legacy transmission system.
