TinyGreenPC launched a Raspberry Pi and Linux based digital signage player that runs on just 7 Watts, and offers optional WiFi and an OPS interface.
The Pi Media Player is one of the most power-efficient signage players on the market, according to TinyGreenPC, a subsidiary of UK-based embedded manufacturer and distributor AndersDX. It helps that the 7 Watt, Raspian Linux-enabled signage player runs on a Raspberry Pi.
The project involves a collaboration with UK-based Silver Curve, which has developed a graphics engine called Aperture that optimizes the VideoCore IV GPU found in the Pi SBC’s Broadcom BCM2835 system-on-chip for digital signage. Aperture features include multiple zones, multiple layers, smooth animation, and cinematic effects such as depth of field, according to TinyGreenPC. The Aperture engine and HD-ready Pi Media Player are supported by signage content management systems including SignageLive, Instore Media (INSM), and Gemasi Italy.

The Pi Media Player is available in standard VESA mountable versions, as well as Open Pluggable Specification (OPS) versions, each of which are also available in “Lite” versions that lack the full versions’ WiFi module and 10-pin GPIO breakout. OPS was launched by Intel in 2010, and began appearing in signage systems in 2011. The spec standardizes signage connectivity using an 80-pin JAE Electronics TX24/TX25 blind mate plug and receptacle connector system to interface the pluggable module and the display.

On the Pi OPS Media Player models, the JAE connector consolidates the standard version’s HDMI, USB, serial, audio, and power interfaces. The OPS design also includes two handle knobs.
According to Paul Mullen of AndersDX, the Pi Media Player and its variants combine the first-generation Raspberry Pi Model B SBC with a customized Anders interface board and casing. He also revealed that a revised model based on the Raspberry Pi Compute Module is due in early 2015.
The Linux-based systems ship with the Raspberry Pi SBC’s standard 512MB of RAM, along with an SD card with 8GB of flash, expandable up to 256GB. All models offer a 10/100 Ethernet port, HDMI 1.3 input/output port, a USB 2.0 port, and an RS-232 port, although, as noted, some of these are consolidated in the JAE connector on the OPS versions. The full versions add WiFi and GPIO.
The Pi Media Player runs on 5VDC power and ships with a 750mAh battery. Operating temperatures range from 0 to 55°C, says TinyGreenPC.
