Abstract
A method of reducing a channel hopping time in an MPEG-2 system decoder which can improve the performance of a receiver by minimizing the response time in the event of changing the receiving channel. According to the method, a predetermined storage region is provided in a DRAM, and packet identifier (PID) values of audio and video signals of each program are stored in the storage region. Thereafter, if a receiving channel is changed, the channel-changing operation is performed using the PID values of the audio and video signals stored in the storage region, and thus the time required for the channel change is shortened, thereby reducing the channel hopping time.
