Abstract: Disclosed herein are an apparatus and method for converting a broadcast signal. The apparatus for converting a broadcast signal includes a demultiplexer unit for receiving a terrestrial broadcast signal and generating a terrestrial signaling signal, a signaling conversion unit for converting the terrestrial signaling signal into a cable signaling signal by parsing the terrestrial signaling signal, a cable multiplexer unit for generating a cable broadcast signal by multiplexing the cable signaling signal, and a cable modulation unit for modulating the cable broadcast signal and transmitting the cable broadcast signal over a cable network.

Abstract: Disclosed herein are an apparatus and method for providing a broadcasting service. The method for providing a broadcasting service is performed using a broadcasting service provision apparatus and a terminal device, and includes performing, by the broadcasting service provision apparatus and the terminal device, initialization using information acquired from a downstream signal received from a Cable Modem Termination System (CMTS), converting, by the terminal device, an upstream signal received from a Cable Modem (CM) into a digital signal, encapsulating the digital signal into an IP packet, and transmitting the IP packet to the broadcasting service provision apparatus, and extracting, by the broadcasting service provision apparatus, the digital signal from the IP packet received from the terminal device, converting the digital signal into an analog signal, and transmitting an upstream signal corresponding to the analog signal to the CMTS.
