According to the channel changing method and system, remote control unit operation behaviors of a user are monitored, when the system detects that the user continuously and rapidly presses keys for multiple times, the Release state of a former key and a Press state of a next key are combined and converted to form a one-time Repeat state, so that only Inforbars of different programs are refreshed, frequency locking is avoided, different PSI/SI (program-specific information/system information) is prevented from being received and analyzed, actual channel changing is not performed, the Release state for actual channel changing is converted into a Repeat state avoiding actual channel changing under the condition of the same channel changing, accordingly, the time occupied by channel changing is greatly reduced, the channel changing speed is greatly increased, channel changing is completed rapidly, and great convenience is brought to the user.
