Abstract
Methods for channel scanning are provided. An embodiment of a method for channel scanning comprises scan progress information stored when interrupting a channel scanning process. A carrier RF subsequent to the most recently processed carrier RF is locked onto with reference to the stored scan progress information when resuming the interrupted channel scanning process. Channel information of a program carried by the locked carrier RF is acquired. The acquired channel information of the program is stored in a channel table.
