Abstract (en)
[origin: CA2736557A1] Method and apparatus for scanning channels of a broadcast receiver are provided. The channel scanning method includes
determining whether to perform an entire channel scanning operation or a partial channel scanning operation in response to a channel scan
command, if the entire channel scanning operation is determined to be performed, performing the entire channel scanning operation by scanning
all channels and storing channel information regarding a channel in which a broadcast signal exists in a channel map, and if the partial channel
scanning operation is determined to be performed, performing the partial channel scanning operation by scanning a channel which is not registered
in a pre-created channel map, and storing channel information regarding the non-registered channel in which a broadcast signals exists in the nonregistered channel map.
