Abstract
A communication apparatus and a method for supporting carrier sense multiple access/collision detection (CSMA/CD) are disclosed. In a home network having a plurality of peripheral apparatuses in one home bus, the communication apparatus includes an interface circuit for transmitting and receiving packet data by being connected to the home bus; a data transmitting circuit for converting transmission data generated from inner peripheral apparatuses into physical transmission data and then for outputting the data on the home bus through the interface circuit; a data receiving circuit for determining whether data transmitted from other peripheral apparatuses through the interface circuit are received in its own peripheral apparatus and for checking a current state of the home bus; a collision detection circuit for continuously detecting a current state of the home bus through the data receiving circuit; and a communication controlling part for controlling data which are output form the data transmitting circuit by detecting a state of the home bus detected from the collision detection circuit.
