[中文适用范围]： IEC 62312系列为音频和视频的同步方法提供了指南。 本部分IEC 62312描述了音频和视频同步的系统模型和通用方法。这些方法不包括信号源和音频再现的空间延迟的同步。 [外文原描述]： IEC TS 62312-2:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 62312-2:2018 gives guidelines for methods of synchronization of audio and video. It describes the system model and general methods for the synchronization of audio and video. The methods exclude the synchronization of the signal source and the spatial delay of audio reproduction. IEC TS 62312-2:2018 cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) fingerprint is newly introduced; b) addition of the synchronization information from fingerprint (SMPTE spec.); c) addition of the method for using the above information.
