A terrestrial digital TV broadcast signal receiver which takes an EPG (Electronic Program Guide) data from a received TV (Television) broadcast signal with respect to each receivable channel, stores the EPG data of each channel into a memory, reads out the EPG data from the memory and displays an EPG of each channel on a screen of a display apparatus when a user chooses to display the EPG, wherein when contents of the EPG data of a channel previously stored in the memory are eliminated with passage of time and finally lost because the contents have finished being broadcast, a TV broadcast signal of the channel is received, new EPG data is extracted from the received TV broadcast signal and the new EPG data is stored in the memory, while electric power of the TV broadcast signal receiver is switched off such that the TV broadcast signal receiver is in a stand-by power state, wherein when the electric power of the TV broadcast signal receiver is in the stand-by power state, an EPG data of a channel which will be lost the earliest is searched among the EPG data stored in the memory, and a time of day when the EPG data of the searched channel is lost is calculated; and when a time for taking new EPG data is reached, a tuner is tuned to the searched channel, a TV broadcast signal is received and a new EPG data is extracted from the received TV broadcast signal and stored in the memory.
