Abstract
A television receiver having: an external input terminal to receive a non-RF signal from a first external device, the non-RF signal being a video and/or audio signal which is not modulated into a radio frequency signal; an RF input terminal to receive an RF signal from a second external device, the RF signal being generated by modulating a video and/or audio signal, and an external-input switching unit to perform switching selection to the non-RF signal received through the external input terminal, wherein the external-input switching unit is capable of tuning in a frequency of RF signal transferred through the RF input terminal to perform switching selection to a receiving channel when the detecting unit detects that an RF signal has been transferred through the RF input terminal.
