A channel switch control method in a digital multimedia broadcasting receiver is disclosed, wherein discrimination is made as to whether a switch to the erstwhile selected channel has been completed in response to receipt of a channel switch command, and if it is determined that the switch operation to the erstwhile selected channel has not been completed, a switch operation to a newly selected channel in response to the channel switch command is delayed until the switch operation to the erstwhile-selected channel is completed and then the channel switch operation is performed, whereby an unstable operation can be avoided resulting from receipt of a switch command to the new channel before a screen output operation relative to the erstwhile-selected channel is completed.
