ABSTRACT:
Disclosed are an apparatus and a method for decreasing a channel change time in a digital broadcasting reception terminal. Starting time information of at least one non-reference channel is selected. When the user selects a non-reference channel, broadcast data thereof is received by using the collected starting time information. The apparatus extracts time offset values between a starting time of a current reference channel and that of each at least one non-reference channel, and then obtains the starting time of each non-reference channel by using the extracted time offset values. When a channel change is performed, the starting time of the non-reference channel is established to receive broadcast data based on the starting time according to a corresponding time offset value. Hence, a time period required for a channel change is significantly reduced.
