In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the edit

31、preting, sound input is the interpreters most important source of information. The image of the speaker and of all visual materials used in the conference is almost as important.New technologies permit different forms of audio and video signals and are now being used increasingly to transmit sound a

32、nd image to interpreters. Their quality determines the conditions of the interpreters work. The transmission mode of sound and image is therefore vital and requirements should be standardized. ISO 2017 All rights reserved vBS EN ISO 20108:2017Simultaneous interpreting Quality and transmission of sou

33、nd and image input Requirements1 ScopeThis document sets out requirements for the quality and transmission of sound and image input to interpreters and specifies the characteristics of the audio and video signals. The components of typical interpreting systems are specified in ISO 20109. Together wi

34、th either permanent (see ISO 2603) or mobile (see ISO 4043) booths, these interpreting systems form the interpreters working environment. In addition to setting out the requirements for on-site interpreting, where participants (speakers and members of the audience) and interpreters are at the same l

35、ocation, this document specifies requirements for different varieties of distance interpreting situations in which the interpreters are not at the same location as one or more of the conference participants.This document also addresses the work of manufacturers and providers of simultaneous interpre

36、ting equipment and technical staff.In conjunction with either ISO 2603 or ISO 4043, this document and ISO 20109 provide the relevant requirements both for the quality and transmission of sound and image provided to interpreters and for the equipment needed in the booths, the conference room and the

37、distant site(s).2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
