Abstract
Provided is a signal processing circuit including an information detection unit (204) that detects signal bandwidth information indicating a bandwidth of a channel signal in a broadcast signal received by a receiving circuit (100) that receives the broadcast signal, and the signal bandwidth information is used for execution of a channel scan.
Claims11
A signal processing circuit, comprising:
- an information detection unit configured to detect signal bandwidth information in a broadcast signal received by a receiving circuit, wherein the received broadcast signal includes the signal bandwidth information at a beginning portion of a frame of the broadcast signal, the signal bandwidth information indicates a bandwidth of a channel signal, the signal bandwidth information is used for execution of a channel scan,
- the information detection unit is further configured to detect a bit string present at the beginning portion of the frame prior to a preamble of the frame, and the bit string represents the bandwidth of the channel signal.
A signal processing system, comprising:
- a receiving circuit configured to receive a broadcast signal, wherein the received broadcast signal includes signal bandwidth information that indicates a bandwidth of a channel signal;
- a signal processing circuit, wherein the signal processing circuit includes an information detection unit configured to detect the signal bandwidth information at a beginning portion of a frame of the broadcast signal;
- and a processor configured to execute a channel scan based on the signal bandwidth information,
- wherein the information detection unit is further configured to detect a bit string present at the beginning portion of the frame prior to a preamble of the frame, and the bit string represents the bandwidth of the channel signal.
