Apparatus for remedying errors in head end monitoring block, and control method therefor |
摘要 |
An apparatus for remedying errors in a head end monitoring block includes an optical transmitting section for transmitting/receiving aerial broadcasting signals and its own broadcasting signals; a host computer for controlling respective sections of a head end; a master control section for monitoring an operating state of a transmitting path of the head end and the codeck boards; a master mother section for receiving certain signals from the master control section so as to connect communication paths between the optical transmitting section, the host computer and the master control section; a slave control section for monitoring the transmission state of a relevant codeck board, and for receiving an error occurrence signal from the master control section so as to carry out the function of the master control section in place of it; and a slave mother section for receiving an error occurrence signal from the master control section so as to connect communication paths between the optical transmitting section, the host computer and the master control section. In operation, if an error occurs in the master control board, the slave control board takes over the function of the master control board to carry out the head end block monitoring task in place of it. A method for remedying errors in a head end monitoring block includes analogous steps.
