and at a rate faster than the predetermined transfer rate via the IP network in the high-speed communication mode, the standard
communication mode and the high-speed communication mode being interchangeably executed;
an acceptor that obtains capability information of a remote apparatus in accordance with a predetermined communication protocol;
and
a controller that selects the high-speed communication mode for execution based on a determination, using the capability information,
that the remote apparatus is configured to execute the high-speed communication mode.
