Transmission interface unit in transmission system

A transmission interface unit in a transmission system wherein time series data is divided into data groups and a data packet comprising reproduction specification time data, said reproduction specification time data specifying the time at which each data piece in the data groups should be reproduced is added to each data packet, is transmitted on a transmission bus in a time division manner, said transmission interface unit comprising:

• a cycle timer for counting a reference time of a home machine based on a reference time on the transmission bus;
• a generation section for generating the reproduction specification time data;
• an addition section for dividing the time series data into data groups, putting into packets, and adding the reproduction specification time data to the data in the packets;
• and
• a rewrite section for rewriting the reproduction specification time data generated by the generation section when the reference time on the transmission bus changes.

• a cycle timer for counting a reference time of a home machine based on a reference time on the transmission bus;
• and
• a controller for controlling:
• generation of the reproduction specification time data;
• division of the time series data into data groups, placement into packets, and addition of the reproduction specification time data to the data in the packets;
• and
• rewriting of the generated reproduction specification time data when the reference time on the transmission bus changes.
