Communication apparatus for multiplexing and communicating a plurality of types of data, communication system, and control method therefor

摘要

When a request to transfer real-time data is generated during transfer of non-real-time data, the transfer of the non-real-time data is interrupted, and transfer of a real-time data frame is inserted. Thereafter, the remaining non-real-time data is continuously transferred. The length of each communication frame generated by dividing the first type of data into a plurality of data and using the divided data is determined depending on whether the second type of data is communicated.
