Abstract
An in-vehicle system includes a basic system provided in a vehicle, and an additional system to be added to the vehicle. When the basic system and the additional system execute processing in cooperation, in a first mode in which transmission and reception of a video signal and an audio signal are not performed between the basic system and the additional system, transmission of a control signal for controlling the additional system is limited to unidirectional transmission from the basic system to the additional system. In this case, in a second mode in which one or more lines of video audio signals each including at least one of a video signal or an audio signal are transmitted and received between the basic system and the additional system, transmission of the one or more lines of video audio signals is limited to unidirectional transmission from the basic system to the additional system.
