Patent ID: 7932957

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; a digital circuit portion that converts the compressed digital signal outputted from the digital demodulating portion into digital video and audio signals; 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, and a connecting portion that connects together conductor patterns between a first circuit board, on which the tuner circuit portion is arranged, and a second circuit board, on which the digital circuit portion, the digital demodulating portion, and the video/audio output circuit are arranged, wherein the receiver apparatus is covered with a chassis over all faces of the receiver apparatus facing outside the receiver apparatus, the first and second circuit boards are separated from each other with a first shield plate, an analog ground pattern of the first circuit board and a digital ground pattern of the second circuit board are electrically connected to the chassis, and the ground pattern of the circuit boards are connected to the chassis with solder applied only on one same face of the circuit boards.
