ELECTRONIC DEVICE, ELECTRONIC DEVICE CONTROL METHOD, AND ELECTRONIC DEVICE SYSTEM

摘要

An electronic device includes: a digital signal transmission/reception unit configured to perform two-way transmission of a digital signal using multiple differential signal lanes prepared at a transmission path with an external device; a transmission path arrangement determining unit configured to determine a transmission path arrangement including the number of use lanes, a use lane number, and a transmission direction by performing communication with the external device using a two-way communication line prepared at the transmission path with the external device; and a transmission path arrangement control unit configured to control the arrangement of the digital signal transmission/reception unit based on the information of the transmission path arrangement determined at the transmission path arrangement determining unit.
