"A company focused on 24 x 7 reliability"


TELEDAC INC. has manufactured message generators and video billboards from 1978 to 2015. Initialy, their products gained wide acceptance by the Canadian cable TV industry. In the 90s, new applications emerged throughout North America in the corporate, public building, school, hospital, and government markets. Teledac equipment was often part of the communication solution provided by local Pro AV Systems Integrators.

A considerable portion of the company's revenues was allocated to a continuous research and development program. IRISTEXT, the latest product line, has been constantly upgraded and refined with new features and innovations. All this without compromising on long term reliability.

Iristext hardware  24 x 7 reliability

IRISTEXT products were designed to operate 24 hours a day, 7 days a week, with a useful life of 15 to 20 years. To achieve this level of reliability, Teledac used a proprietary video processor board. All items subject to mechanical usage, such as cooling fans and hard disks, were eliminated from the main unit. Pages are stored in non-volatile electronic memory and protected from power failure by a replaceable lithium battery. Careful design had restricted components to those items specific to message generation. Furthermore, the dependability of the electronic parts had been increased by reducing energy consumption which permits an internal operating temperature significantly lower than that of personal computers.

During manufacture, each IRISTEXT unit was subjected to a severe 7-day high temperature "burn-in" process. This to identify and replace any defective components before they leaved the plant. At the final stage, the unit was assembled with options ordered by the client. Before shipment, the system is calibrated, fully tested and given a specific data file. This included an order-specific control form detailing all the relevant parameters. So, there is a useful reference whenever the user requires assistance or needs to upgrade the system.

Bypassing the weak link: peripherals

For high resolution still video pictures and video file broadcasting, Teledac used hard disk storage and an industrial grade computer. Keeping in mind the overall system dependability, this option was interconnected as a peripheral to the IRISTEXT main unit in such a way that it is automatically bypassed in the event of most partial or full peripheral failures.

The use of a separate peripheral unit also allowed the system to stay "on air" with alpha-graphic pages while the peripheral unit was serviced.

These are just some of the reasons why, for more than 35 years, Teledac has been the choice of clients posting "the right message at the right time".
