Abstract

A satellite television signal distribution device comprises a storage unit, a satellite channel resetting device, a tuning and demodulation device and a processing unit; the storage unit is used for storing a first frequency comparison table; the satellite channel resetting device is used for receiving a plurality of satellite television broadcast signal and transfering the plurality of satellite television signals to various transmission frequencies according to a first frequency comparision table in order to output a frequency shift signal which comprises a second frequency comparison table; the tuning and demodulation device is used for capturing the frequency shift signal and tunning and demodulating a second frequency comparision table in the frequency shift signal; and the processing unit is used for automatically updating the first frequency comparision table according to the second frequency comparison table.

Description

technical field [0001] The invention relates to a satellite TV signal distribution device, in particular to a satellite TV signal distribution device with single cable and multiple users that can be updated automatically. Background technique [0002] To watch satellite TV, it is necessary to install a dish antenna to receive satellite signals, and then use a low-noise block converter (LNB) and a single-cable satellite signal switching device to process the satellite signals and output them to the client. However, the single-cable satellite signal switching device is only used by a single user. For a multi-dwelling unit (MDU), such as a multi-user residential environment such as an apartment or a building, a multi-user satellite TV signal distribution device is required. [0003] The satellite frequency of the program offered by the operator may change due to the expiration of the satellite lease or other factors. However, the software or frequency comparison table built in...
