摘要： A television signal receiver receives both an ordinary television signal, such as a PAL television signal, and a high-definition television signal, such as a MAC television signal. The television signal receiver has a memory for storing data indicative of whether an indicated channel contains a PAL television signal or a MAC television signal. Based on the data read from the memory, a CPU controls a PAL/MAC selector to select a PAL television signal or a MAC television signal.
