    摘要： A receiver apparatus 3 has a digital circuit portion 13 that converts a compressed digital signal outputted from a digital demodulating portion 12 into digital video and audio signals and a video/audio output circuit 14 that converts the digital video and audio signals outputted from the digital circuit portion 13 into analog video and audio signals. With this configuration, a video/audio processing IC for digital signal processing no longer needs to be mounted on the circuit board of a video display apparatus 4, and thus a receiver system can be realized with a video display apparatus having a simple configuration.

    摘要： A wireless receiving device of the present invention is so arranged that (i) a high-frequency circuit section is provided on a front surface of a printed board and (ii) a digital video signal processing section and a wireless LAN digital signal processing section are provided on a back surface of the printed board. Further, an earth pattern is provided in a middle position between the front and back surfaces of the printed board, so that (i) the high-frequency circuit section and (ii) the digital video signal processing section and the wireless LAN digital signal processing section are shielded from one another using electromagnetic shielding by the earth pattern. Thus, when members that are commonly used for the wireless LAN and for wireless video reception are formed on a single printed board in order to reduce the size of the printed board, it is possible to effectively reduce the lowering of signal quality caused by the noise.

    摘要： A wireless video receiving apparatus is provided with a first voltage-controlled clock generation portion that can generate a video dot clock having a relatively high frequency and a second voltage-controlled clock generation portion that can generate a video dot clock having a relatively low frequency. A digital video signal compressed on the side of a transmitting apparatus is fed to a digital video signal decompression portion. The frequency of a horizontal synchronizing signal of an analog video signal fed to the side of a transmitting apparatus has been measured on the transmitting apparatus side, and a clock generated by the first or second voltage-controlled clock generation portion according to the frequency thus measured is fed to the digital video signal decompression portion, and then the compressed signal is decompressed.
