Abstract:
A terrestrial broadcast tuner section is disposed in an area A1, and frequency-converts an externally supplied terrestrial broadcast signal into an IF signal. A terrestrial broadcast analog demodulation section is disposed in an area A3, and demodulates the IF signal frequency-converted by the terrestrial broadcast tuner section. A satellite broadcast tuner section is disposed in an area A2, and frequency-converts an externally supplied satellite broadcast signal into a signal having a frequency band lower than that of the satellite broadcast signal. A digital demodulation section is disposed in an area A4, and demodulates the signal supplied from either one of the terrestrial broadcast tuner section and the satellite broadcast tuner section. With this arrangement, a broadcast receiving apparatus easily changeable from the one for analog and digital broadcasting to the one for digital broadcasting only can be provided.
