Introduction

The iec61937-13 project is a C-based implementation of the IEC 61937-13:2018 standard and covers the encapsulation of an MPEG-H bitstream in IEC data bursts.

The following pages illustrate the use of IEC 61937-13 specification for the transport of an MPEG-H 3D Audio Stream between devices connected by an interface conforming to IEC 60958, in particular SPDIF, HDMI, and HDMI ARC. It explains the concepts used in IEC 61937-13 including delay calculation related to IEC 61937-13 and some aspects of using IEC 61397 for HDMI and HDMI ARC.
