<p><P>PROBLEM TO BE SOLVED: To solve the problem that for a conventional receiving circuit, elements having breakdown voltages higher than those of elements used for other circuits should be used in a connection detection circuit, and thus a circuit scale becomes large. <P>SOLUTION: A receiving circuit receiving transmission data including image data by a digital signal has: a first clock detection circuit 10 for detecting the presence or absence of a read clock used for reading a unique ID of reception-side equipment; a second clock detection circuit 12 for detecting the presence or absence of the transfer clock of the transmission data; and a link state detection circuit 14 into which a result detected by the first and second clock detection circuits 10, 12 is input to detect a link state with transmission-side equipment based on at least one of the read and transfer clocks. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
