Understanding IEC61937 13 - Fraunhofer-IIS/iec61937-13 GitHub Wiki

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

Please note: even though the IEC61937-13 standard defines various operation modes, the following pages will be restricted to the required operation modes implemented by this project.

• Readers guide to IEC61937-13
• Timestamp handling
• Latency
• HDMI forward connection
• HDMI (e)ARC and SPDIF
