 The HDMI source end provides +5 V and GND for DDC and CEC communication. Through the DDC, the source end obtains the sink end parameters, such as the RX capabilities. The CEC is optional. It is used to synchronize the control signals between the source and sink ends to improve user experience. There are four TMDS channels between the HDMI source and sink ends. The TMDS clock channel provides clock signals for TMDS, and the other three channels transmit audio, video, and auxiliary data. HPD is the hot plug detect port. When the sink end is connected, the source end responds by using an interrupt program.
