Abstract
A blind scan method includes setting a tuner to scan a first spectrum block with a first center frequency as a center and determining whether the first spectrum block comprises a possible signal; adjusting the tuner to scan a second spectrum block with a second center frequency as the center according to a first rise point and a first drop point when it is determined that the first spectrum block comprises the possible signal; and determining whether the second spectrum block comprises a valid signal.
Claims20
A blind scan method, comprising:
- setting a tuner to scan a first spectrum block with a first center frequency as a center and determining whether the first spectrum block comprises a possible signal;
- adjusting the tuner to scan a second spectrum block with a second center frequency as the center according to a first rise point and a first drop point when it is determined that the first spectrum block comprises the possible signal;
- and
- determining whether the second spectrum block comprises a valid signal.
A non-transient computer readable medium, comprising at least one program command configured to operate a method, wherein the method comprises:
- setting a tuner to scan a first spectrum block with a first center frequency as a center and determining whether the first spectrum block comprises a possible signal;
- adjusting the tuner to scan a second spectrum block with a second center frequency as the center according to a first rise point and a first drop point when it is determined that the first spectrum block comprises the possible signal;
- and
- determining whether the second spectrum block comprises a valid signal.
A control circuit, configured to set a tuner to scan a first spectrum block with a first center frequency as a center and to determine whether the first spectrum block comprises a possible signal, to adjust the tuner to scan a second spectrum block with a second center frequency as the center according to a first rise point and a first drop point when it is determined that the first spectrum block comprises the possible signal, and to determine whether the second spectrum block comprises a valid signal.
