HDMI sources

HDMI from DVI interface technology, they are primarily based on Silicon Image's TMDS signal transmission technology as the core, which is why the HDMI interface and DVI interface adapter PCB Screw Terminal Block conversion through reason. Silicon Image's HDMI eight sponsors are the only IC design and manufacturing company, is a leader in the field of high-speed serial data transmission technology, because the TMDS signal transmission technology to be mentioned below is that they developed, so here is a little mention it. TMDS (Transition Minimized Differential Signaling) is also known as Transition Minimized Differential Signaling refers to the XOR and XNOR logic algorithms, such as converting the raw signal data into 10, after the first 8 data from the original signal obtained by the operation, after 9 indicates operation mode corresponding to the first 10 to a DC balance (DC-balanced, that is to ensure that the channel encoding process in the DC offset is zero, the level conversion achieves matching between different logical Dvi to hdmi adapter interfaces) conversion data transmission to the differential transmission mode. This algorithm is such that the upper punch and the lower transition of the transmission signal offset is small, tends to be DC-balanced data transmission, the signal transmission line for the electromagnetic interference is reduced to improve the speed and reliability of signal transmission.
