ENENSYS LAUNCHES rEWS VIDEO-BASED REGIONAL EMERGENCY WARNING SYSTEM FOR DVB-T NETWORKS

In advance of this months Broadcast Asia, ENENSYS, designers and manufacturers of digital TV transmission technologies, has today announced the launch of rEWS a receiver-agnostic system providing video-based emergency warnings on a regional basis of dangerous weather events and natural disasters for DVB-T2 networks.

Providing TV-based emergency warnings on a regional basis is a primary requirement across many countries and regions such as ASEAN. But using receiver-based methods is complex, requiring special receiver software in order to display the emergency alert and even then they only support audio, text and graphics. Alternatively, using a standard middleware like HbbTV or MHEG-5 means the alert display is implemented as an application but this requires additional receiver cost and comprehensive receiver conformance testing. Middleware solutions are also limited to audio, text and graphics.

ENENSYS rEWS is a video-based solution that overcomes these limitations. The emergency alert is delivered as a TV service, using standard broadcast video and audio. When an alert is triggered, all normal programming is interrupted and replaced with the emergency alert service, which is usually provided by the government disaster coordination centre. As the alert message is standard video and audio all basic set-top boxes and iDTVs can receive the warnings without modification and, in addition, the alert message can use video as well as audio, text and graphics

Richard Lhermitte, VP of Sales and Marketing, says, rEWS is based on our T2Edge technology, which inserts local/regional content in DVB-T2 networks. T2Edge with rEWS allows normal programming to be interrupted to play out the emergency alert, replacing all the normal A/V transport stream components with the emergency alert A/V content. Very importantly, it is fully compatible with single frequency networks this is vital. It is of course, also regional in the way that it can be activated, avoiding unnecessary warnings to unaffected populations.

ENENSYS Technologies has many years of experience in the design and manufacturing of digital TV transmission technologies. Its products sit between encoding/multiplexing and transmission, facilitating signal distribution over a wide variety of networks including IP.
