Abstract
An apparatus and method for supporting a PC communication and internet service while supporting D-CATV and VOD services by using a settop box connected to a network for D-CATV and VOD services, without a separate communication equipment. The apparatus includes a PC interface installed in the settop box to communicate with the PC; and an internet gateway prepared at a head end of the D-CATV to provide an internet service channel between a backbone internet and a D-CATV subscriber. The settop box includes a controller for analyzing a previously designated VC (Virtual Channel) cell for SLIP (Serial Line Internet Protocol) within of data received from the network and for transmitting the VC cell together with a SLIP header to the PC. The controller also is for separating the SLIP header from the data received from the PC and for transmitting to the network the designated VC cell together with an IP (Internet Protocol)-over-ATM (Asynchronous Transfer Mode) header.
