PURPOSE:To perform balanced transmission by twist pair lines with high performance without using any balanced transmission element by procesisng an input video signal and generating the same phase signal and an inverse phase signal. CONSTITUTION:A transless video transmission circuit 1 is provided with a phase converting part 2, inverse phase transmitting part 3 and the same phase transmitting part 4. At the phase converting part 2, a video signal inputted from a terminal 5 is generated into the same phase signal with the same phase as the video signal and the inverse phase signal with the inverse phase by using a phase converting transistor 8. At the same phase transmitting part 4, the same phase signal inputted to the same phase signal transmitting transistor 16 is sent to the first lines of a pair of twist pair lines connected to a terminal 20b. At the inverse phase transmitting part 3, the inverse phase signal inputted to an inverse phase signal transistor 14 is transmitted to the second lines of a pair of twist pair lines connected to a terminal 20a. |
