Provided is apparatus and method for transforming cable channel. The apparatus includes a data mixing unit for receiving and mixing a band data and a first broadband data, to thereby generate a second broadband data of a broadband cable channel, and a channel adapting unit for dividing a band data from the second broadband data received through the broadband cable channel, bypassing the second broadband data to a first subscriber apparatus and transmitting the band data to a second subscriber apparatus.

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.
