In a transmitter side of an image packet communications system, a transmission clock signal is generated subordinately synchronized to a reference clock signal. Based on the transmission clock signal, a transmission standard signal is generated as synchronous with the reference clock signal. Further, a packet generator generates image packets based on the timing of the transmission clock signal with reference to the transmission standard signal, with image packet headers attached thereto. In a receiver side of the image packet communications system, a reception clock signal is generated subordinately synchronized to the reference clock signal, so that the reception clock signal is synchronized with the transmission clock signal. A packet receiver separates the image packet headers from the image packets, and the buffer controller generates a reception standard signal with reference to the image packet headers based on the reception clock signal, thereby controlling the writing and reading operation of the image packets to and from a buffer group. Thus, the transmitter and receiver can be stably synchronized, despite occurrence of errors or packet losses, with simple configuration.
