The present invention provides a reception terminal apparatus that can receive signals in a stable state with a simple configuration and hence is highly suitable for mobile reception. The reception terminal apparatus includes an input section that selectively inputs a reception signal from reception signals of a plurality of types in different states of reception, a demodulation section that demodulates the reception signal input by the input section, an error detection section that detects errors in the stream data obtained by the demodulation section by demodulating the reception signal, and a control section that determines if the number of errors as detected by the error detection section exceeds a threshold value or not and controls the input section according to the outcome of determination, the reception signal to be input to the demodulation section by the input section being switched when the number of errors exceeds the threshold value.
