Abstract
A low-speed signal conversion module for a DP interface is provided, including a protocol parsing module, an encoding module, a decoding module, a sending link, and a receiving link. The protocol parsing module is configured to parse a DP protocol, and send a low-speed signal of the DP interface to the encoding module, or send an output signal of the decoding module to the DP interface. The encoding module is configured to perform encoding in different forms respectively according to different outputs of the protocol parsing module, and transmit the encoded signal to the sending link. In the present invention, different combinations of combined AUX, HPD and null signals are line-encoded respectively according to characteristics of a DP protocol.
