A data transmission terminal apparatus and a data transmission method for maintaining a data transmission between the terminals irrespective of the state of a clock signal associated with a transmission data packet. The data transmission terminal apparatus multiplexes an image data signal and an other data signal to generate a data packet synchronized to a reference clock signal included in the image data signal, and relays the generated data packet to a transmission path. The apparatus comprises first packet generating means for multiplexing the image data signal and the other data signal to generate an image data packet, second packet generating means for multiplexing the other data signal and dummy data to generate a dummy data packet, clock monitoring means for monitoring the reference clock signal to generate a state indicating signal indicative of the state of the reference clock signal, and output relaying means for switching between the image data packet and the dummy data packet in accordance with the state indicating signal for relaying to the transmission path.
