Abstract
An HDMI transmission device includes a packetizer circuit and a processor. A control method of controlling the HDMI transmission device includes performing a fixed rate link training, upon passing the fixed data rate link training, the processor transmitting an initial gap packet generation command to a controller of the packetizer circuit to output a selection signal to the packetizer circuit, so as to output an initial gap packet, when video data is not ready, continuously outputting the initial gap packet, when the video data is ready and a format change of the video data is detected or a signal abnormality unrelated to hot-plugging is detected, the processor transmitting a subsequent gap packet generation command to the controller to determine whether a block boundary is reached, and the controller switching the selection signal upon reaching the block boundary for the packetizer circuit to output the subsequent gap packet.
