V30.02 software update for onboard displays on board autocares

[RELEASE 21.12] V30.02 Functionality description R21.12

Committed to the continuous improvement of the services we provide in our software for screens on board bus fleets, we have made many improvements to our system, so that all our customers now have an improved version with our version V30.02 .

The improvements in this new version are:

The user of the screen can use their bluetooth headphones to listen to the contents offered by it. To do this, on the screens that have this technology* (Allwinner 9” and 10” and A33 7” 9” 10”) we will see a new button with the “Bluetooth” logo that allows pairing the headphones.
Once this button is pressed, a typical standard interface appears where the user must select the name of their device. Once selected, the interface will confirm with a message on the screen that the device has been paired. From that moment the screen audio is heard on that paired device.
*Does not work on 7” and 9” rockchip screens. These screens do not have bluetooth at the hardware level.

Basically, the Widevine software, patented by Google, is a technology that manages DRM (Digital Rights Management, that is, digital rights management). These allow, therefore, to restrict the access of consumers to video content, based on rules defined by the creator of the content.

Our AOD system implements and supports this technology that ensures that the content offered is distributed by authorized companies and complies with current legislation on audio visual reproduction.

Well, this software, like any other, evolves and launches new versions of it, so our systems have had to be updated to be compatible with the latest version of it.


This functionality allows a "transmitter" device (Tablet or mobile), which has our casting app, to broadcast its content to the rest of the vehicle's screens (up to 50). What is done is to "duplicate" the screen of said sending device, so that whatever is done on it will be sent to the rest of the screens. It is similar to “screen sharing” in a video conference, in fact it is the same technology.

Therefore, this functionality allows showing fragments of videos and annotations on the same screen, corporate presentations, etc.

Practical utilities can be:


Internal message:

After the tests carried out on a series of selected vehicles, it was observed that when coverage was lost and the internal buffer consumed, the player could not play the IP television stream again, so the "broadcast" was interrupted.

External message:

Improved internal buffer management to achieve fluid playback even in areas without coverage.
