信息技术——沉浸式媒体的编码表示——第31部分：触觉编码

[中文适用范围]： 此文档规定了支持高效传输和渲染触觉信号的技术，用于广泛场景下沉浸式体验的播放。该文档详细描述了一种稳健的编码表示方式，涵盖了当今设备最常用的两种触觉感知：振动触觉和运动感知。其他触觉模态的支持也已被集成。 这种编码表示方式允许将描述性和量化数据以易于人类阅读的JSON格式进行编码，并用于交换目的；同时也提供了一个压缩位流版本，优化了内存使用和分发目的。这种方法还能够满足市场对与描述性及量化格式兼容性的期望，以及3D沉浸式体验、移动应用和其他分发目的之间的互操作性。 本文件中关于解码器的信息是规范性的，而关于编码器和渲染器的信息则是提示性的。 [外文原描述]： This document specifies technology that supports the efficient transmission and rendering of haptic signals for the playback of immersive experiences in a wide variety of scenarios. The document describes in detail a robust coded representation of haptic media covering the two most popular haptic perceptions leveraged by devices today: vibrotactile and kinaesthetic. Support for other haptic modalities has also been integrated. The coded representation allows to encode both descriptive and quantized data in a human readable JSON format used for exchange purposes, and a compressed bitstream version, optimised for memory usage and distribution purposes. This approach also allows to meet the expectations for compatibility with both descriptive and quantized formats, as required by the market, as well as interoperability between devices for 3D immersive experiences, mobile applications and other distribution purposes. Information provided in this document related to the decoder is normative, while information related to the encoder and renderer is informative.
