Abstract:
A packet output device for formatting serial data into packets and for transmitting resulting data packets, the device comprising:a clock signal generator for generating a clock signal defining clock time;a data packet generator for generating each data packet and for generating time data corresponding to the data packet, the time data defining an output time of the data packet based on the clock time; anda packet transmitting circuit for receiving the data packet and the corresponding time data and for transmitting the data packet based on the corresponding time data in accordance with the clock time,wherein the time data generated by the data packet generator includes a transmission start time before which the corresponding data packet is prevented from being transmitted, and a transmission end time after which the corresponding data packet is prevented from being transmitted; andwherein the packet transmitting circuit compares the clock time with the transmission start time and the transmission end time of the time data, in case where the clock time is before the transmission start time, a vacant packet for indicating absence of data to be transmitted is output, and in case where the clock time is between the transmission start time and the transmission end time, the data packet is output.
