IEC 61606-1:2009(E) is applicable to the basic methods of measurement of the audio characteristics of the digital audio part of audio and audiovisual equipment for all of consumer use, professional use and personal computer. The common measuring conditions and methods, described in this standard, are used for the measurement of the performance characteristics of equipment having an audio bandwidth equal to approximately one-half of the sampling frequency of a system, where the audio information is processed in the form of digital data. CD players, DAT recorders, digital amplifiers, digital sound broadcast receivers and television broadcast receivers with digital sound are examples. It describes test methods for equipment which has digital input with analogue output and analogue input with digital output. Future revisions of this standard will cover digital-in/digital-out and analogue-in/analogue-out tests. It constitutes a technical revision. The significant technical changes with respect to the first edition are the following: - changed the period of preconditioning; - add A weighting filter in measuring instruments; - correct the wrong reference number; - some inappropriate descriptions have been improved.

The purpose of this Technical Report is to serve as a standard method to test Total Radiated Sensitivity (TRS) of a category c) terminal specified in IEC 62002-1. This is a practical measure of the radiated sensitivity as it takes into account both the terminal antenna efficiency and possible terminal generated additional noise. Moreover it can be used directly in the link budget calculations for the network coverage predictions. The motivation for the TR has been the lack of suitable measurements methods to characterise the terminal antenna in common and practical way. As the 3GPP TR 25.914 method is in many ways suitable for the task, it was decided to de

This International Standard provides a subjective (or perceptible) and statistical method of assessment of overall, or end-to-end, difference of delays between real world and reproduced scenes in terms of video and accompanying audio recoded in a medium. This International Standard does not specify limiting values for those results obtained by the application of the provisions in this standard. It excludes applications to professional broadcast systems.
