Channel scanning method for digital video broadcasting satellite signal
A channel scanning method for Digital Video Broadcasting-Satellite (DVB-S) signals is provided. The method includes: scanning a radio frequency (RF) signal according to a normal frequency step; when the Nth channel is detected, obtaining a difference between a low boundary of an Nth channel and a high boundary of an (N−1)th channel; and, when the difference is within a predetermined bandwidth range, scanning the RF signal between the high boundary of the (N−1)th channel and the low boundary of the Nth channel according to a narrow frequency step. The normal frequency step is greater than the narrow frequency step.
