Voluntary Standards Cover the Spectrum: from Closed Captioning for 3D Programming to Water Filtration

New York, Feb 20, 2013

In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes a series of snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:

Closed Captioning for 3D Programming
Third-dimensional projection has been in existence since 1915 but was largely unsuccessful due to the lack of technology and standardized formats to support widespread implementation. In the 1980s and ’90s, 3D programming experienced a resurgence driven by the technological renaissance in the United States, and today 3D films are a common offering.

Closed captioning was developed in the 1970s to allow persons with hearing disabilities to have access to television programming by displaying the audio portion of a program as text on the screen. In 1993 the Federal Communications Commission (FCC) required all analog televisions to contain closed captioning display capabilities, and in 2002 the FCC extended that requirement to include digital televisions (DTV).

A recently published American National Standard (ANS) from the Consumer Electronic Association (CEA) marries 3D technology with DTV closed captioning. CEA 708.1-2012, Digital Television (DTV) Closed Captioning: 3D Extensions, specifies signaling to allow CEA-708 caption services to be rendered with stereoscopic (3D) program content.

CEA, an ANSI organizational member and accredited standards developer, is a non-profit organization dedicated to the consumer technology industry. CEA serves its membership and stakeholders through market research, advocacy, educational programs, technical training, standardization, and certification programs.

Water Filtration
According to the Environmental Protection Agency (EPA), Americans collectively drink more than one billion glasses of tap water every day. But before drinking water is deemed safe for human consumption, it must be filtered. To ensure the filtration process is effective and results in safe drinking water, the American Water Works Association (AWWA) recently released AWWA B101-2012, Precoat Filter Media.

The revised ANS covers disposable filter materials used to precoat filters for water supply service applications. Revisions to the standard include the addition and revision of definitions, as well as revisions to typical physical and typical chemical properties of precoat media used in water treatment.

An ANSI organizational member and accredited standards developer, AWWA works to unite the entire water community to protect public health and welfare, and provide safe, sufficient, and sustainable water for all. AWWA initiatives include advancing education, science, management, government policies, technology, and standards for the water industry.
