ABSTRACT:
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.
