Historical U.S. Standards 

The Alliance for Telecommunications Industry Solution (ATIS) is a U.S. based standards organization that is accredited by the American National Standards Institute (ANSI). The Telecommunications (T1) Committee created standards and technical reports (TR) on video quality assessment in the late 1990s and early 2000s. ITS personnel contributed to these documents, which influenced international standards developed later.

ANSI T1.801.02-1996

“Digital Transport of Video Teleconferencing/Video Telephony Signals - Performance Terms, Definitions and Examples.”

ANSI T1.801.02 provides a dictionary of digital video performance terms and impairments. This standard includes a video tape that illustrates common digital video impairments such as tiling, smearing, edge busyness, error blocks, and jerkiness. Thus, this standard gives end-users and service providers a common language for discussing digital video quality.

ANSI T1.801.03-2003

“Digital Transport of One-Way Video Signals - Parameters for Objective Performance Assessment (Revision of T1.801.03-1996)”

ANSI T1.801.04-1997

“Multimedia Communications Delay, Synchronization, and Frame Rate Measurement”

ANSI T1.801.04 defines measurement methods for audio delay, video delay, and audio-visual synchronization. These performance parameters are important for interactive (i.e., two-way) telecommunication services.

ANSI T1.TR.72-2001, 2003

“Methodological Framework for Specifying Accuracy and Cross-Calibration of Video Quality Metrics”

ANSI T1.TR.73-2001

“Video Normalization Methods Applicable to Objective Video Quality Metrics Utilizing a Full Reference Technique”

ANSI T1.TR.74-2001

“Objective Perceptual Video Quality Measurement Using a Peak-Signal-to-Notice-Ratio (PSNR) Full Reference Technique”

ANSI T1.TR.75-2001

“Objective Perceptual Video Quality Measurement Using a JND-Based Full Reference Technique”

ANSI T1.TR.77-2002

“Data and Sample Program Code to be used with the Method Specified in Technical Report T1.TR.PP.72-2001 for the Calculation of Resolving Power of the Video Quality Metrics in Technical Reports T1.TR.PP.74-2001 and T1.TR.PP.75-2001”
