Abstract
A protocol conversion circuit and a protocol conversion method are provided. The protocol conversion circuit includes a DisplayPort™ (DP) receiver, a control analysis circuit, a downstream transmitter and a frame buffer. The DP receiver analyzes a DP signal to obtain video data and packet information. The control analysis circuit determines whether the packet information indicates that a live function or a panel replay (PR) function is activated, and controls, in response to determining that the live function is activated, the frame buffer to store received current video data and transmits it to the downstream transmitter; and controls the frame buffer to discard the received current video data, or update previous video data stored in the frame buffer with a specified range in the current video data, and sends latest video data to the downstream transmitter, so as to output a target signal to the second electronic device.
