are sightseeing, commuting, waiting in line, or traveling to their next destination (Figure 1).


Vehicle-mounted digital signage also provides unique opportunities. Media players equipped with geolocation technology can cue advertising based on the vehicle’s location and time of day.


Welcome to the Cruel Outdoors The growing availability of higher definition electronic bill- boards and outdoor displays presents tough challenges. Higher resolutions and dynamic content require higher performance media players. Outdoor locations require rugged housing to ensure a long life and wireless connec- tivity for locations without wired Ethernet.


Depending on the installation’s location, players must also sustain sub-zero temperatures or blazing heat. In many climates, a system must operate in both. The player must be reliable and sturdy enough to function in places where a service technician may not inspect it for months or years. Similarly, the player must support remote content updates to save the cost of dispatching service crews.


An Even Harder Life on the Road While facing the same unforgiving exposure to extreme temperatures and need for remote manageability, in-vehicle digital signage must also overcome the following additional challenges:


• Shock and vibration. Media players must withstand the frequent shocks and constant vibrations typical of a public bus or train.

• Limited power. High-resolution digital signage can require considerable power to run all the electronics, but in- vehicle displays and players have to share battery power with critical vehicle systems.


• Input voltage variances. Buses and trains generally operate on 24/28VDC power, while taxi battery voltages typically fluctuate between 9V and 14V.


• Power control. Players must incorporate ignition-sensing power control systems so signage operates only when the vehicle is running and does not drain the battery when garaged. Equally important, media players need a sequenced shutdown so when the vehicle is turned off, the operating system does not crash and introduce errors in the software.


• Wireless connectivity. Remote manageability and content management require wireless connectivity for vehicle connection anytime, anywhere.


Players Designed for Harsh Environments With a background in industrial PC products, IBASE saw an oppor- tunity to use the advanced features and graphics capabilities of the 5th generation Intel Core i7 processor family to create rugged media players for these use cases. The resulting players include the IBASE SE-92 Extreme Environment Digital Signage Player and SE-602 Extreme Environment In-Vehicle Digital Signage Player.


The IBASE SE-92 meets the requirements for extended duty cycles in outdoor environments.


A Media Player for the Urban Outdoors The SE-92 is designed specifically for extended duty cycles in outdoor environments like bus shelters, railway platforms, busy street cor- ners, parking lots, highway rest areas, and outdoor information kiosks (Figure 2). The fanless system is unaffected by dusty environments, and it starts and operates continuously at ambient temperatures ranging from a frigid -40 °C to a scorching 75 °C.


The SE-92 operates off any DC power source between 7V and 36V, allowing it to tap the common 12V, 24V, and 36V power rails that power high-intensity LED arrays. For energy-efficient operation, IBASE’s iSMART green technology enables power on/off scheduling and power-resume functions.


The integrated dual DVI-I interface supports either DVI-D or VGA displays and includes a built-in extended display-identification data (EDID) emulation function. EDID enables the player to recognize and make optimal use of display capabilities. The player’s two dual- channel DDR3L-1600 sockets support up to 16 GB of memory.


The SE-92 includes dual Gigabit Ethernet (GbE), two USB 2.0 ports, two USB 3.0 ports, and an optional 64 GB mSATA SSD drive for fast system boot and low heat emissions. M.2 and Mini PCI Express* slots and an
