InfoComm Releases Standard on Projected Image Contrast Ratio

InfoComm International's latest standard, 3M-2011 Projected Image System Contrast Ratio, has been approved by the InfoComm Board of Directors. The standard provides metrics for measurement and requirements for minimum contrast ratios for rear and front projection audiovisual projected image systems.

3M-2011 Projected Image System Contrast Ratio, which applies to both permanent and temporary installations, defines projected image system contrast ratio and its measurement. This standard defines four contrast ratios based on content viewing requirements. The system contrast ratio refers to the image as it is presented to viewers in a space with ambient light. Metrics to measure and validate the defined contrast ratios are also provided. A one-page overview can be found at "This standard puts the needs of the viewer ahead of all other considerations," said Randal A. Lemke, Ph.D., Executive Director and CEO, InfoComm International. "The standard’s requirements move beyond individual performance factors of a projector and a screen, because the contrast ratio they can deliver is ultimately affected by the light in the space."

3M-2011 Projected Image System Contrast Ratio provides important metrics for evaluating, planning and designing projected image system installations, setting minimum contrast ratios, and a procedure for measuring the contrast ratio provided by the system.

Digital copies of the standard are available for purchase in July at InfoComm's consensus standards development process is accredited by ANSI, a private, non-profit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment systems. ANSI is the sole U.S. representative of the two major non-treaty international standards organizations, the International Organization for Standardization (ISO), and, via the U.S. National Committee (USNC), the International Electrotechnical Commission (IEC). Accreditation by ANSI signifies that the procedures used by InfoComm International in connection with the development of American National Standards meet the Institute's essential requirements for openness, balance, consensus and due process.

Founders of Extron, Sennheiser Win Adele De Berri Pioneers of AV Award

Extron president and founder Andrew Edwards and the late Professor Dr. Fritz Sennheiser have been issued the Adele De Berri Pioneers of AV Award. The awards were presented at the ribbon-cutting ceremony at InfoComm 2011, the world's largest commercial audiovisual tradeshow.

Andrew Edwards' vision and leadership have made Extron one of the leading providers of innovative products, training, and customer support to the professional AV industry. Nearly three decades ago, Edwards identified one of the biggest challenges facing the audiovisual industry — the inability for different AV components to work together in a seamless way — and created a company dedicated to creating the networking hardware needed for effective systems.

In the earliest days of Extron's history, he implemented S3 — Service, Support, Solutions, a customer support philosophy that has served the AV industry well. Using a "listen first, then respond" approach, Edwards has empowered the Extron staff to take the time to fully understand the customer's needs and system goals before developing or recommending a system solution. His dedication to customers through the development of comprehensive training, industry-leading support, and innovative products is an underlying force that has strengthened the AV industry, and has made possible a higher quality of presentation technology.

"Andrew Edwards pioneered the systems integration movement and now has positioned Extron for the net-centric AV industry," said Randal A. Lemke, Executive Director and CEO, InfoComm International. "By focusing on creating system-wide solutions and placing paramount importance on industry training and customer service, Andrew Edwards has paved the path of success for countless AV professionals and customers."

The late Professor Dr. Fritz Sennheiser founded what is now Sennheiser Electronic GmbH & Co. KG, a major international company. The family firm, located in Wedemark, near Hannover, Germany, has a global workforce of more than 2,100 employees. Sennheiser has production sites in Germany, Ireland and the USA, manufacturing microphones, headphones, conference and information systems, headsets and audiology products.

Overcoming considerable adversity, including an economic depression, World War II and even death threats against him and his engineers, Professor Dr. Sennheiser triumphed by building an innovative team of engineers who would create some of most recognizable and long-standing microphones and headphones in history. From his days as a student developing a reverberation unit used at the opening ceremony of the 1936 Olympic Games, to overseeing his company create the first set of open headphones, Professor Dr. Sennheiser stood for excellence in engineering innovation.

"InfoComm is pleased to recognize the technological and business achievements of Fritz Sennheiser," said Lemke. "He was an industry legend whose steadfast commitment to excellence will never be forgotten."

The Adele De Berri Pioneers of AV Award is issued annually by InfoComm International to current or former employees of InfoComm member companies who have made an important contribution to the science of audiovisual technology, whether as an inventor or thought leader who advanced the development of a new product, segment or service of the AV industry. The award is sponsored by Da-Lite and Sound & Communications.
