Our Convergence Collision with Electronic Signage Networks

The networked digital signage industry is now poised to deliver the logical evolution to central sound - central video.

Electronic Signage Networks represent the integration of now available technologies, and at a time when public safety needs are higher than ever before.


Electronic Signage offers a cost -effective way of communicating public safety and alert information while providing new revenue for property managers and retailers. This need and the growing capabilities of electronic signage in areas of image provisioning, connectivity, display triggering are fueling the installations of signage and kiosk networks. Electronic Signage Networks (ESN) integrate display (such as LCD, plasma, etc), input devices, digital storage and communications technologies (such as WiFi) under the control of a software called "Dynamic Image Provisioning Applications" (DIPA) to support public safety, information and commercial goals.

Providers of key elements, such as the control software are able to provide information and contacts useful to network planning. Considerable information is available at www.adsn.ca

Technology: Breakthroughs in communications, control software as well as monitoring and image triggering devices have been made as display technologies have advanced. ESN offers an important, powerful tool for public safety. Its increasing cost effectiveness, allows for displays in more numerous locations including for example, exit stairways.

WiFi (Wide area Fidelity) has seen a fundamental development with WiFi -Plus multi -polarity antennas. The obstruction penetrating capabilities enable communications in urban, retail and rural environments that has not been possible, and further does so at 3 to 5 times lower cost. This technology is enabling more and larger "hotzones", including citywide areas.

Control software has emerged at a new plateau of functionality as the "Dynamic Image Provisioning Application" (DIPA). The DIPA backoffice system being specified into electronic signage networks can accommodate display screen -splitting, triggered and override messaging, interoperability and file format handling and scalability to several thousand displays. This allows for "dual use" deployment; displays used for both commerce (retail, advertising, branding, pricing, training, etc.) and public safety and information (alerts, direction, etc.). The new capability of DIPA responds to dual -use ESN

Monitoring and Image Triggering: Display devices offer a location to house monitoring equipment providing input to trigger a human decision or automatic message. Cameras, audio, infrared or heat sensors can feed directly into a staffed security or response center in a transit systems, retail locations, secure areas, etc. Using the features in DIPA, threat signals could automatically trigger an image display to provide information or instructions, in the same way that traffic counters and motion detectors could trigger traffic routing, arrival and departure information.

PureLink - HCE III TX/RX: 4K HDR over HDBaseT Extension System w/ Control and Bi-Directional PoE

The HCE III Tx/Rx HDBaseT™ extension system offers full HDMI 2.0 compliance supporting HDR (High Dynamic Range) and 4K@60Hz with 4:4:4 chroma sampling. Featuring PureLink's proprietary Pr©cis codec, a light compression technology, the HCE III can transport Ultra HD/4K, multi-channel audio, and High Dynamic Range (10 bits support) content over a single CATx cable. The HCE III provides HDMI extension up to 130 feet (40 meters) at Ultra HD/4K and up to 230 ft. (70 meters) at 1080p over category cable with embedded multi-channel audio, CEC pass-through, bi-directional RS-232 and IR control, and PoE - all with zero loss and zero noise. The HCE III Tx/Rx also supports Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio plus LCPM (up to 192 kHz). Additionally, the low profile "slim box" enclosure design make the HCE III ideal for limited space installation environments, such as behind flat panel displays and video walls.
