Abstract:
1. A combined communication and broadcasting dual switching system, comprising: broadcasting transmission means configured to convert a Radio Frequency (RF) broadcast signal into an optical signal, and to output the optical signal; an Optical Line Terminal (OLT) configured to comprise dual lines, and selectively output an Internet data signal; an optical detection unit configured to detect a line from which the Internet data signal is being output, from among the dual lines of the OLT; an active path determination unit configured to determine that the line, detected by the optical detection unit, is an active path, and output a switching control signal; an optical switch unit configured to receive the optical signal from the broadcasting transmission means, and switch to the active path in response to the switching control signal output from the active path determination unit; and a combining unit configured to receive the optical signal output after having been switched by the optical switch unit, receive the Internet data signal from the OLT, multiplex the received optical signal and the received Internet data signal, and output a multiplexed signal.
