Abstract: Provided are an apparatus and method for broadcasting-communications convergence in a hybrid fiber coax (HFC) network. The apparatus includes an optical connector configured to receive broadcast data and communication data from a cable broadcasting station through an optical cable, a channel switch configured to receive the broadcast data from the optical connector and select a piece of broadcast data to be transmitted to a subscriber from among pieces of the broadcast data, and a convergence processor configured to receive the communication data from the optical io connector, receive the selected piece of broadcast data from the channel switch, generate broadcasting-communications convergence data by multiplexing the received communication data and the selected piece of broadcast data, and transmit the broadcasting-communications convergence data.
