Patent ID: 7907218

Claim:
A receiver apparatus comprising: a tuner circuit portion that converts a radio-frequency signal received by an antenna into an intermediate-frequency signal; a digital demodulating portion that converts the intermediate-frequency signal outputted from the tuner circuit portion into a compressed digital signal; an intermediate-frequency processing circuit portion that converts the intermediate-frequency signal outputted from the tuner circuit portion into an audio intermediate-frequency signal; a digital circuit portion that converts the compressed digital signal outputted from the digital demodulating portion into digital video and audio signals; and a video/audio output circuit that converts the digital video and audio signals outputted from the digital circuit portion into analog video and audio signals, wherein the intermediate-frequency processing circuit portion includes an intermediate-frequency processing IC that converts the intermediate-frequency signal into the audio intermediate-frequency signal, the digital circuit portion includes: a video/audio processing IC that decodes compressed digital video and audio signals; and a video/audio processing memory that stores the compressed digital video and audio signals and decoded digital video and audio signals, the digital demodulating portion includes a digital demodulating IC, which is a processing IC for converting the intermediate-frequency signal into a digital signal, the intermediate-frequency processing IC, the video/audio processing IC, and the digital demodulating IC are arranged in positions apart from one another on a same mount face, and the intermediate-frequency processing circuit portion is electromagnetically shielded from the video/audio processing IC and the digital demodulating IC.
