US 2017/0373390 A1 · SATELLITE FINDING APPARATUS AND SATELLITE FINDING METHOD

Abstract

The disclosure provides a satellite finding apparatus and satellite finding method, includes a set-top-box (STB) and a satellite antenna receiving device (SARD). The STB receives signals from the satellite antenna receiving device, and the STB comprises a central processing unit, a power transforming unit, a satellite switching judging module, a driving controlling module and a current detecting module. The SARD includes motors, tuners and antennas. The disclosure further provides a satellite finding method. The satellite finding apparatus will perform short-circuit detection if a switch of satellite is determined upon. The disclosure enables the motor only at the time when the satellite finding apparatus needs to find the satellite, it can save energy and prevents the destroying of the motor.
