Abstract
A channel scanning method in a multi-channel digital broadcast is provided for enabling a user to identify the broadcast contents of a channel being currently received with accuracy during the channel scan, even though the broadcast contents may change within a channel scanning time period. In one embodiment of the channel scanning method, a receive channel is switched at predetermined intervals (the scanning time period), it is checked whether the broadcast contents of the channel being received currently, after the channel switching, will change within the scanning time period, and a time period for receiving the channel is prolonged, if the broadcast contents will change.
