CTA's Most Popular Standards
1
ANSI/CTA-861-G
A DTV Profile for
Uncompressed High-Speed
Digital Interfaces
CTA's most downloaded standard
describes how set-top boxes and
TV sets (and other devices sharing
digital video signals) can communicate
their capabilities to one another and
communicate the characteristics of the
video they're sharing.
2
ANSI/CTA-2034-A
Standard Method of
Measurement of In-Home
Loudspeakers
This standard describes how to measure and report the directivity of a
loudspeaker, whether it stands by itself
or is mounted on a wall or ceiling. It
also describes how to use this directivity
data to estimate the in-room frequency
response that research has shown
correlates well to subjective listening
preferences of consumers.

ANSI/CTA-2065
Physical Activity
Monitoring for Heart Rate
This health, fitness and wellness standard addresses heart rate measurements among a diverse group of people.
Each wears the device to be tested
along with another heart rate measuring device known to be accurate. Heart
rate is measured under various standardized conditions.
6
CTA-2069
Definitions and
Characteristics of Augmented
and Virtual Reality Technologies
CTA's first augmented reality/virtual
reality standard defines terms like "360°
spatial audio," "spherical video," "roomscale VR" and more.
The joint CTA/National Sleep Foundation
document defines characteristics of sleep
and the functionality needed in consumer
sleep measuring devices to measure
those characteristics. For
example, it defines

ANSI/CTA-708-E
Digital Television (DTV)
Closed Captioning
The digital TV closed captioning standard describes how to
incorporate closed captioning into the digital TV signals
used by local over-the-air
broadcast stations in the U.S.
and other countries.
9
ANSI/CTA-2010-B
Standard Method of
Measurement for Subwoofers
This standard measures the performance
of powered and passive subwoofers and
describes how to determine the sound
pressure level from a subwoofer, and how
to determine if the subwoofer is suitable
for quiet, moderate, loud or very loud listening environments.
10
ANSI/CTA/NSF-2052.3
Performance Criteria and
Testing Protocols for Features
in Sleep Tracking Consumer
Technology Devices and
Applications
The joint CTA/National Sleep Foundation
standard for measuring the performance
of sleep tracking devices describes how
to confirm the accuracy of a particular
device's performance when it comes
to measuring specific elements or characteristics of the sleep process.
