Abstract
In transmission of video signals of a plurality of channels using a digital interface in conformity with the high definition multimedia interface (HDMI) standard, a transmission minimized differential signaling (TMDS) mixing circuit and a TMDS separation circuit are provided, to perform time-division transmission of TMDS data of the video signals of the plurality of channels at a frequency higher than the transmission rate of the video signals. Video signals of a plurality of channels are therefore transmitted via an inexpensive type A connector and cable.
