要約
(EN)

A data transmission system includes a first apparatus that is connected to a first external apparatus using the first transmission scheme and a second apparatus that is connected to a second external apparatus using the first transmission scheme. The first apparatus is connected to the second apparatus using a second transmission scheme that is different from the first transmission scheme. When the operation mode of the first apparatus in the first transmission scheme and the operation mode of the second apparatus in the first transmission scheme are different, data in the first external apparatus or the second external apparatus is transmitted to the second external apparatus or the first external apparatus, respectively, via the first apparatus and the second apparatus.
