Abstract: During 1993-1994, the T1A1 subcommittee of the American National Standards Association (ANSI) accredited Alliance for Telecommunications Industry Solutions (ATIS) conducted an objective video quality metric validation test focused on video teleconferencing applications. (T1A1 is now known as PTSC QoSR— Packet Technologies and Systems Committee, Quality of Service and Reliability.) This article summarizes the T1A1 video quality subjective test, with a focus on information that a current researcher needs to effectively use this dataset. The T1A1 video sequences and differential mean opinion scores (DMOS) are available on the Consumer Digital Video Library (CDVL, www.cdvl.org).

Keywords: video quality; video teleconferencing; subjective testing; video quality metrics
