PMX refers to the technology developed by Pelmorex to generate local weather information on The Weather Network. PMX consists of computers, typically installed at a cable headend, that takes data fed to it (the video feed of The Weather Network, forecast information, and triggers to run said forecasts) and packages it for broadcast. Unlike the Weather Star systems, it does not generate full graphical or video segments, rather the information is super-imposed over the main video feed.

History

PMX was developed by Pelmorex in 1995 as a standard localization system that would replace the Weather Star 4000 units and the text based Weather Star 3000s that were still used in smaller communities.[1] The PMX technology quickly rolled out starting 1996, with all communities receiving the new units by the end of 1997. To this day, PMX generates local weather information to over 1200 communities across Canada.

Timeline

Severe weather warnings (specifically during Severe Thunderstorm, or Tornado Warnings) are displayed as a red bar with text at the bottom of the screen. Less severe weather warnings are displayed as a red full page overlay with text during the first part of the Local Forecast.

Products

PMX is primarily used on segments that involve local weather information, notably during regular Local forecasts. Over the years PMX has been used for local tagging with advertisements, usually with listings of local dealers, and with "weather-triggered" advertising.

PMX units at major satellite TV providers display forecasts for a list of major Canadian centres. However few smaller satellite providers in certain regions (e.g. SaskTel) use customized PMX units that cover its geographical area. Conditions are shown for multiple cities at one time and box areas intended for different forecast products on normal PMX systems are repurposed: the 4x2 grid used for the 7-Day Outlook displays precipitation forecasts for the next 24 hours for 14 cities in Saskatchewan.

The technology has also been used for the MTS TV Weather Channel in Manitoba.

PMX would be used to display warnings and alerts with the proposed "All Channel Alert" system.
