Abstract

The invention is suitable for the field of a set top box and provides a star finding method based on DiSEqC1.2 and the set top box. The method comprises the following steps of obtaining a local longitude, a target satellite and a selected transponder; causing a polar axis motor to return to zero; determining the rotating direction of the polar axis motor according to the local longitude and the longitude of the target satellite; controlling the polar axis motor to rotate to the rotating direction; when the selected transponder is detected to be in a locking signal state, stopping the rotation of the polar axis motor. The technical scheme has the advantage of high precision.

Description

technical field [0001] The invention belongs to the field of set-top boxes, and in particular relates to a method for finding stars based on DiSEqC1.2 and a set-top box. Background technique [0002] DiSEqC (Digital Satellite Equipment Control, digital satellite equipment control) is a communication protocol. In the existing satellite set-top boxes, the DiSEqC1.2 protocol is usually supported. In the DiSEqC1.2 protocol, the star-seeking operation is a common Operation, the most important part of the star-seeking operation is to control the polar axis motor to rotate to the exact longitude. In order to control the polar axis motor, the command to rotate the polar axis motor to the east and west is set in the set-top box. The user first selects the desired The transponder to be tuned, and then rotate the polar axis motor by sending the DiSEqC1.2 east / west command, when the user judges that the signal of the currently tuned transponder is locked, send the polar axis motor stop ...
