Resilient. Secure. Unique.

World-class wireless video transmission that allows remote viewing securely over cellular/constrained networks with near-zero latency.

TVI is our patented video codec technology. Originating from neural network research at the University of Strathclyde in Glasgow, TVI provides real-time video streaming over bandwidth-constrained or congested networks. With customers in more than 30 countries, TVI-based solutions are relied upon by some of the world's most demanding defence and law enforcement customers.

​Real-time video over wireless networks

From the outset, TVI has been designed to ensure video can be delivered over wireless networks with under 0.5 second latency. Unlike standards-based codecs such as H.264 and MJPEG which struggle with the variability of bandwidth on wireless networks, TVI actively monitors the bandwidth at each instant and using this information adjusts the amount of image detail so that it never exceeds the bandwidth available to it.This enables a constant frame rate and avoids missed frames or a build-up in time delay. Uniquely, TVI can stream real-time video over wireless networks at under 10 kbits per second. 

End-to-end security

TVI has been designed to provide users with military-grade security. TVI can be deployed with packet-level AES256 bit encryption to minimise encryption overhead. This gives users complete confidence that, with no adverse effect on video latency or cost of data transmission, TVI delivers virtually unbreakable video security between encoder and viewing application without the need for expensive and complex virtual private networks (VPNs). 

 

How does it work?

Our TVI technology is designed to work cost effectively over low and bandwidth-constrained networks.

Given the unique design of the codec, TVI provides users with the ability to modify dynamically both the frame-rate of video and the maximum bandwidth a video stream can use for transmission. With typical bandwidth savings of around 60 per cent over standards-based codecs, this capability also allows users to manage the cost of video-data transmission. 

Real-time video over congested fixed networks

The spiky bandwidth profile delivered by standards-based codecs means network managers are seldom happy to deliver video services over corporate networks. The ability to set precise rules on bandwidth to be used per video stream means TVI can be used to offer real-time video services over congested fixed networks without risk of disruption to other business critical services. 

 

High resolution video retrieval from the edge

Even when streaming over ultra-low bandwidth links, TVI users never miss the detail. Utilising edge-based recordings, TVI provides a range of tools to allow users to quickly select and retrieve the original high quality imagery as provided by the camera, while continuing to  provide live video. 

 
Multiple viewers for situational awareness

TVI's unique server-based architecture allows, subject to security rules, many viewers to watch a single camera in real time. Any camera connected to a TVI encoder can therefore be watched from anywhere in the world, providing situational awareness for different groups within a organisation and speeding up decision-making, based on being able to see what is going on. 

Mission-critical scalability and resilience

With its military heritage, TVI has been designed to deliver the highest levels of scalability and resilience to ensure it meets the mission-critical needs of some of the most demanding users of live video. TVI has been designed with a number of features to ensure performance can scale dynamically with different loads on the system and that single points of failure are minimised.

Interoperability

Many TVI users utilise a range of other technologies as part of their broader platform, including command and control systems and video-management systems. A number of TVI software development kits (SDKs) are available to facilitate native integration, as well as TVI ONVIF Gateway, a stand-alone interoperability tool that allows paid integration with ONVIF compliant systems.  

Video-analytics ready

Digital Barriers provides an increasing range of video analytics technologies and many of these have been designed to work in a tightly integrated way with TVI. More information on this topic will be released through 2016.
