摘要： Disclosed is a method for a handover of a digital broadcasting reception terminal employing a time division multiplexing scheme, which periodically receives broadcast data through each of one or more broadcasting channels provided in a predetermined frequency band, the method including the steps of: when broadcast data of a channel selected by a user in a current cell is received, detecting handover determination information from the received broadcast data; determining if it is necessary to perform a handover to an adjacent cell by using the handover determination information; searching channels provided by the cell to which the terminal will be handed over for a channel providing broadcast data equal to that provided by the selected channel, when it is determined that it is necessary to perform a handover; and when a channel providing broadcast data equal to that of the selected channel is found, performing a handover to a corresponding cell and receiving broadcast data of the found channel. Accordingly, the digital broadcasting reception terminal employing the time division multiplexing scheme can quickly and stably perform a handover, so that the user can view a seamless broadcast although he/she moves from a current cell to an adjacent cell which uses a frequency and/or broadcast data reception time point different from that of the current cell.
