Full Description

Scope

This standard allows the creation of instrumentation technology for consistent measurements of video-related time-interval errors (TIEs).

Purpose

This standard defines a set of measurements to provide metrics to quantify the timing perturbations of a video signal s synchronization information. The goal of this measurement standard is to provide consistent and meaningful timing measurements of both digital (discrete-time) and analog (continuous-time) video that can be correlated to video system performance. To achieve this goal, this standard makes use of the traditional engineering concept of analyzing the timing perturbations in terms of a sinusoidal frequency spectrum, rather than applying statistical metrics to time-domain measurements. A partitioning (filtering) of that spectrum is introduced and metrics are assigned for quantifying the timing perturbations so that performance limits, which are directly related to limitations of video timing recovery, buffering andsynchronization, can be set and verified.

Abstract

New IEEE Standard - Active.Reaffirmed March 2010. A set of metrics and methods to enable consistent measurement of the components of timing interval error in video synchronization signals is provided. By partitioning the spectra into regions of jitter and lower frequency wander (characterized as frequency offset and drift rate), timing performance can be better quantified for consistent control over nontraditional networks.
