A display apparatus is configured to activate a display control apparatus by transmitting an activating signal to the display control apparatus in response to determining that a start condition is satisfied. In response to receiving the activating signal, the display control apparatus is enabled to transmit a video data corresponding to a video to be displayed in a display in the display apparatus.

Display control apparatus, display apparatus, display control system, and storage medium

A vehicular display device is used in a vehicle and displays an image received from a drawing device. The vehicular display device includes an image display unit, a notification unit, an image notification determination unit, a drawing request unit, a correspondence identification unit, and a notification execution unit. The image display unit executes notification by displaying the image. The notification unit executes notification by at least one of audio and light. The image notification determination unit determines whether the vehicle is in an image notification state. The drawing request unit requests the drawing device to draw the image corresponding to the image notification state. The correspondence identification unit identifies the correspondence notification action. The notification execution unit causes the notification unit to execute the correspondence notification action.

Vehicular display device

A LIN receiver includes a voltage divider that divides an input voltage and outputs the divided voltage, and a peak hold circuit that outputs a peak voltage of the input voltage. The LIN receiver is configured to generate a threshold voltage to be used for determining a voltage signal of a communication bus. The threshold voltage is generated from a voltage signal of the communication bus such that the peak value of the voltage signal (i.e., equivalent to a battery voltage) is held by the peak hold circuit and divided by the voltage divider. Although the communication bus is connected to an on-vehicle battery of which voltage varies with time, by using the voltage signal of the communication bus, a 5V system ECU can generate a threshold voltage which varies responding to the variation of the battery voltage. Hence, the voltage signal can be determined correctly as either high or low level.
