The HDMI 2.1 TX Subsystem supports CTA 861-H (https://cta.tech/) Dynamic
HDR metadata info frame and HDR10+ VSIF (https://hdr10plus.org/). Dynamic HDR
support is user-configurable in the Vivado IDE. To
enable or disable Dynamic HDR support, select the Dynamic HDR
support check box. When Dynamic HDR
support is enabled, a separate memory mapped AXI4 interface (
M_HDR_AXI) is added to
the IP. The memory mapped interface runs on
The HDMI 2.1 TX Subsystem supports the following Dynamic HDR features:
- Dynamic HDR metadata length up to 65535 bytes
- Insertion of dynamic HDR EMPs in the video stream, based on the FAPA_start_location
- Support for CTA 861-H dynamic HDR info frames
- HDR dynamic metadata according to the syntax specified in Annex R
- HDR dynamic metadata carried in supplemental enhancement information (SEI)
messages according to ETSI TS 103 433-1 Note: For more information, see https://www.etsi.org/deliver/etsi_ts/103400_103499/10343301/01.02.01_60/ts_10343301v010201p.pdf.
- HDR dynamic metadata carried in a color remapping information SEI message
according to Rec. ITU-T H.265 Note: For more information, see https://www.itu.int/rec/T-REC-H.265.
- HDR dynamic metadata carried according to the syntax specified in Annex S
- Graphics overlay flag (GOF) carried according to the syntax specified in Annex T
- HDR10+ VSIF Support
- The GOF info frame is not supported through the memory mapped AXI4 interface. You need to configure the GOF via the software. The GOF info frame will be created inside the IP.
- Only Dynamic HDR info frames are read from the memory using a memory mapped AXI4 interface. To send static HDR info frames, use AUX packet APIs. See AUX Packets for details.
