"It’s not size of a business that counts in today’s business world. What really makes the difference is specialized know-how and the experience born of 25 years of successful activity."


Revised 7.20.2010

Computer Modules, Inc., today based in San Diego, was founded in 1982 by an engineer who after graduation from University of Waterloo in Canada worked at Central Dynamics Ltd. in Canada, Tektronix in Canada, and Matrox in Canada and the USA. Our original products were Multibus cards and CMI became a leader in a niche until the industry died as the PC took over industrial control. Later in the early 90's CMI focused on high speed data communications cards. We once again evolved to a leadership role with x.25 communications cards until Cisco took over the data com market. We were really wondering where to go next. In 1999 we created a low cost DVB ASI PCI interface card for someone who did not want to pay $5000 for a high end card. The rest of the story is now visible in our product line today...

Engineering for CMI was originally done in Canada by Linear Systems Ltd. We were very closely linked and essentially operated as one. Engineering, Manufacturing and Marketing, sales, support, and integration are done today in San Diego. The core team who developed our current products has been with the companies since the early 80's. Today we have a world class team of hardware and software engineers who have learned to overcome issues with "buggy" Chips, PCI interfaces, FPGA's, Surface Mount manufacturing and even Windows 95/98/2000/XP/Vista drivers. Because of this experience CMI/Linear has a thorough understanding of digital TV technology.

Our first "broadcast" product was the MPEG Shuttle which is a system product that marries MPEG-2 encoders with our own T1 and E1 interfaces. We pioneered inverse mixing of MPEG-2 over our T1 cards and created our own CSU/DSU's. Next came the DVB Master 1 in 1999. Next came the ATSC Master and the DVB Master FD. Others in far away places make copies sometimes. In January 2002 we introduced the IP Caster, our Linux based DVB to IP encapsulator. Others spent over 30 million dollars to develop similar products. We developed ours at the request of Nortel Networks at a cost of $300,000. It has built-in features such as SNMP management, supports unicast and multicast technology and other IP layers. From there we introduced T-Streamer/XXX, our industry and cost leading DVB Streamer. We believe that most of the world's STB boxes are tested with it.

In the spring of 2003, as a joint effort with our partner company Cypress Semiconductor, we introduced a new technology for us -- SMPTE 259M interfaces and Quad density DVB ASI. In 2003, due to a customer's request, we created the world's first DVB ASI Video TimeShifter, a low cost device that allows networks to time shift their video feeds.

Our growth between 2004 and 2007 has been very rapid. We grew by over 120% over 3 years by successfully supplying:

  • Thousands of DVB ASI PCI cards to the major Video Server companies of the world
  • Many HD Encoders to the US Navy and major sports stadiums against well established competitors.
  • DVB H test equipment to many of the Telecomm companies in the USA
  • Digital Video Modulators to several major retail chains
  • ASI to SMPTE 310 converters as used in major call letter stations
  • The world's first HDMI to HD SDI converter

In 2006, and 2007 we have earned local recognition by the SD Business Journal as one of the fastest growing private companies in both San Diego and the USA. We will be included in INC magazine's 2008 list of fastest growing companies. We are proud.. but remain humble about our many accomplishments.

The story continues as we rush towards a challenging future...


Today we continue with Research and Development efforts into key technologies in the TV, computer and communication fields. Not only do we maintain our products' functionality in step with developments in the Broadcast Industry, we are expanding our product line. The path we take for expansion is determined by what key technologies we think are important to automation in the TV industry.

The Future

We have big plans to become a major player in the worldwide TV equipment business. We are however in no huge hurry to get there. We are a private company with no debt and a conservative, doable, growth plan. As a potential customer you need to know this. It means that we will be around years from now when you need help with your products. And, then as now, our products will be at the cutting edge of technology with a clear path to new technologies.


Our vision is to create and sell state-of-the-art, cost efficient, DVB ASI, SMPTE 310M, SMPTE 259M, SMPTE 292M, and HDTV products and services that meet the evolving needs of our Broadcast Oriented customers, enabling them to develop solutions that result in profits and success by lowering their development and ongoing costs. Since 1982 we have been focusing on relationships and not on merely individual transactions. This "long run" attitude has positioned CMI to be here for customers of all types both small and large. We are here to serve you and exist only because we offer superior value to the rapidly evolving Broadcast Industry.

An Interesting -- Possible -- Factor In our Success:

The Long Tail Principle: "The falling cost of production, distribution, and storage of products is allowing niche producers like us to cater to narrower market niches. Which we do!!  In fact the aggregate value of the niches can exceed the value of the mainstream products."
