标准摘要
[中文适用范围]： IEC 61937-2:2021+AMD1:2026 CSV 规定了用于传输非线性PCM编码音频位流的数字音频接口，该接口采用IEC 60958-1和IEC 60958-3标准。本文档规定了突发信息（burst-info），用于描述突发有效载荷中所包含数据的内容信息。IEC 61937-2:2021 取代了2007年发布的第二版、2011年的修正案1和2018年的修正案2。本版构成技术修订。与前一版相比，本版包括以下重大技术变更：a) 新增了MPEG-D USAC、ACX、ACX HBR2、ACX HBR4和ACX HBR8等音频数据类型；b) Pe中的数据类型字段已扩展并激活。 [外文原描述]： IEC 61937-2:2021+AMD1:2026 CSV specifies the digital audio interface to convey non-linear PCM encoded audio bitstreams applying IEC 60958-1 and IEC 60958-3. This document specifies burst-info, which defines content information about the data contained in the burst-payload. IEC 61937-2:2021 cancels and replaces the second edition published in 2007, Amendment 1:2011 and Amendment 2:2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) new audio data-types of MPEG-D USAC, ACX, ACX HBR2, ACX HBR4 and ACX HBR8 have been added; b) extended data-type field in Pe has been activated.
