摘要
A system for transmitting closed caption data is a method for transmitting a closed caption of a terrestrial broadcasting service as a cable broadcasting receiver. To this end, the system identifies a packet protocol to which a terrestrial broadcasting signal is transmitted, extracts closed caption information from either a first terrestrial broadcasting packet or a second terrestrial broadcasting packet based on the identified packet protocol, and encodes the extracted closed caption information into an audio and a video for a terrestrial broadcasting so as to transmit to the cable broadcasting receiver.
