THE ARCHITECTURE BEHIND AN AUTOMOTIVE DIGITAL SIGNAGE SOLUTION

A  Digital Signage platform that keeps its tracks!

Automotive communication opportunities remain largely underexploited. The Swiss company NAVORI, a global leader in Digital Signage software, takes the lead in this market segment with the release of their Navori QL GPS Trigger module.

Any public transportation company (train, tramways, bus, taxi, limousine…) can now deploy a state of the art on-board Digital Signage System that keeps its track based on the renowned QL software platform.

Public transportation passengers are a classic example of what in marcom terminology is described as ‘captive audience’.  Traditionally public information as well as product promotions are broadcasted in a simple – dull loop. The more signage content is dynamic, the higher the catch rate on the audience. Matters to diffuse relevant content.

QL Player is offering location based content and audio triggering based on GPS data retrieved in real time from connected to the on-board vehicle screens.

Relevant content, location based does the trick. In fixed locations where enough bandwidth is available there is no real constraint, certainly not when deploying QL. But when it comes to efficiently operate such a communications scenario in moving vehicles such as busses, trains and taxi’s, the technical challenges are huge.

QL Player – the client software deployed on professional automotive hardware is capable of triggering specific content based on a real time system read-out of GPS data. Hence the vehicle’s location is known by the player.

This background GPS data triggers content that is real time location based, such as the announcement of the next bus stop up to public or tourist information. Even promotions related to local business can be included. Real time information such as latest news feeds or (local) weather information can be included, all in full HD broadcast TV quality.

GPS TRIGGER is a plug-in for QL PLAYER that retrieves the content and data feeds as following:

Upon arrival of the f.i. a bus or train at the terminal, media content and data are uploaded to the player by ‘Wi-Fi-docking’ – connecting to a unique and secure IP address to update the player. When out of reach of the docking signal the player switches to a 3G or GPRS connection. If the update of players is incomplete at departure time of the vehicle, the 3G connection takes over at Wi-Fi signal loss and completes the upload and also starts reading in all live data feeds such as news ticker RSS data, weather applets etc. until the next secure WiFi docking site takes over.

This secures and balances the communication load and costs.

The average data consumption for the network management (household data such as reporting and media statistics only – media upload and real time data volumes not included) based on a 24/7 calculation measured 100 Mbit/month or less only, whereas any other comparable machine-to-machine deployment architecture eats between 1 to a dazzling 3 GB per month.

This data is monitored by the GPS TRIGGER and based on certain threshold values – geographical zone information – content is triggered relevant to the position of the vehicle. This content typically is audio and visual communication of ‘next stop’- ‘current stop’ – trajectory information – etc.

This information can be complemented with f.i.  travel time delay, roadblock, deviation and other real time data through Wi-Fi (docking) or 3G secure connections.

All different transportation trajectories are managed this way, even if they are random as in the case of a taxi or limousine service.

Since the application synchronizes with Google Maps, the trajectory and impact resolution can be defined at QL Content manager level in a concise and easy to use interface.
