Professionally built for the job

Unlike other approaches, Tetrus is a dedicated display controller built specifically for the task of efficiently and effectively delivering passenger information to the travelling public. Tetrus needs no keyboard, no mouse, no upgrades, no security packages, no additional graphics cards, no additional memory, no fans and no licences – it is built for the job.

Common Platform

By creating a common platform and open architecture, Tetrus strengthens and widens the product reach across multiple industry sectors where electronic displays are required. It continues in the tradition of and commitment to innovation, bringing an increased richness of function to Infotec displays whilst maintaining the core values of reliability, resilience and cost-effectiveness.

Tetrus is a powerful purpose-built controller; with no unnecessary parts or third-party software to detract from the task of displaying passenger information

Excellent graphical / audio presentation

For the travelling public, the power of Tetrus enhances our display capabilities, allowing high definition video and graphics to be presented with beautifully smooth transitions and scrolling as standard. Beyond the pixel perfect visual presentation, Tetrus can also process and broadcast high definition audio and a high quality Text-To-Speech (TTS) feature is optional.

Self-healing Technology

For the asset owners and maintainers 24/7 operation is essential. To help achieve this, Infotec has developed self-healing technology which its Tetrus controller employs to minimise any potential downtime. It can detect and recover itself from many of the issues experienced by passenger information displays including managing the ‘Instant Power-Off’ scenario by quickly rebooting as soon as power is restored:

• Tetrus monitors its operation and takes necessary action if failures are detected
• Low level hardware watchdogs incorporated in all subsystems
• tsPlayer monitors the software operation and will take action if failures detected
• Fast boot and hardware power-down during system resets
• Full interface and power-supply control over connected hardware, TFT panels, communications modules, system stirrer-fans etc.
• Instant power-off file system – No shutdown procedure required

"I am impressed with the video performance, the transitions are fantastic”.

tsPlayer

To support the Tetrus controller, Infotec has developed the dedicated tsPlayer software specifically for passenger information displays. By separating the data from the script, we can ensure the presentation of the data is in a consistent manner. The software allows customers to easily programme their own displays using LUA scripting whilst providing the travelling public with beautifully realised graphics with buttery smooth transitional effects.

tsPlayer provides several benefits, including:

• Programmable by customers or Infotec
• Scripts can be created in days rather than weeks
• No licensing costs
• Or constant upgrades
• Single package – no Windows, no graphics cards, no third-party software

Primary passenger information is obviously the priority but the potential to show additional content in a variety of format is essential to the travelling public. These include:

• Special information
• Information at times of disruption
• Onward travel options
• Planned engineering works
• Security alerts
• RSS Feeds for news, weather, etc.
• Marketing and advertising material

tsPlayer: Protocols

tsPlayer uses Infotec’s standard open source TDP protocol to interface to the displays. TDP is a data only protocol that contains service information without the need for verbose data structures and complex presentation rules which are handled separately by scripts running of the Tetrus display controller. By keeping the data levels down, Infotec displays can use a wider variety of communications channels including 2G/GPRS, 3G, 4G, Radio, WiFi, RS485 and Ethernet. This ability means that there is little loss of functionality even on very low bandwidth connections.

TDP even allows for the transfer of files over low bandwidth and multi drop (daisy chains) comms interfaces.

By separating the data from the script, Infotec ensures the presentation of the data is controlled in a uniform and professional manner

If the TDP protocol doesn’t suit your needs, you can add your own. Our tsPlayer software allows you to do this with the minimum of effort or complexity. Your script can intercept any or all of the communications channels into the Tetrus controller. Your protocols can even run in parallel with TDP if required.
