Description

A method for monitoring satellite broadcastings receiving device and an apparatus therefor}

The present invention relates to satellite broadcasting, and more particularly, to a method for remotely monitoring a state of a satellite broadcasting optical receiver for receiving satellite broadcasting and a technology for providing the monitoring apparatus.

Satellite broadcasting is a broadcasting service that receives broadcast signals shot from the ground and receives them from satellite orbit satellites in space and retransmits them to satellite broadcasting antennas on the ground. The C band (4.6 GHz), the Ku band (12/14 GHz), or the Ka band (20/30 GHz) are typically used for each satellite, with dedicated frequencies for communication with terrestrial stations or satellite broadcast antennas.

The satellite broadcast antenna includes a low noise block-converter (LNB) for receiving a high frequency signal transmitted from a satellite and converting it into an intermediate frequency (IF) domain.

The satellite broadcasting signal received by the satellite broadcasting antenna and converted into IF is applied to the set-top box (STB) to provide a broadcasting service to the subscriber.

Satellite broadcasting has the advantage that service can be opened by providing independent satellite antennas to subscribers without the establishment of wired infrastructure, which requires a large investment cost and maintenance cost, while using high frequency signal with high straightness between satellites and satellite broadcasting antennas. Accordingly, there is a disadvantage in that service opening is difficult when a shadow area is generated by the surrounding feature. In addition, due to the characteristics of the satellite signal transmission process transmitted through the atmosphere, there are frequent cases in which the service is interrupted because it is impossible to receive normal satellite signals in bad weather such as snow or rain.

In order to solve this problem, a satellite broadcasting optical relay apparatus which converts a satellite broadcasting signal received through a large satellite antenna into a satellite broadcasting-optical signal and transmits it to a receiving device located at a far distance using an optical fiber transmission path is used.
