VERTEX GLOSSARY / METADATA CONTROL

HDR / InfoFrames

Real-time HDR metadata injection/extraction plus AVI InfoFrame, VSIF and other InfoFrame manipulation.

SIMPLY PUT

Besides the picture, HDMI sends small labels that say what kind of picture it is, for example 'this is HDR'.

These labels are called InfoFrames, and HDR metadata is one of them.

The Vertex can read these labels, block them, or replace them with your own.

WITH THE HDFURY VERTEX

Can the HDfury Vertex read and change HDR metadata and InfoFrames?

YESYes. It captures and decodes HDR, AVI and VSI InfoFrames, can inject your own, or can block the incoming ones. Custom and disable settings stay on after power cycles, so turn them off when you are done (p.32–35).

How to use it with the Vertex:

HDR INFOFRAME tab: read CAPTURED HDR METADATA (p.32).
Build your own values, then Create IF and Send HDR; untick Enable Custom HDR to stop (p.32–33).
Disable HDR removes all incoming HDR metadata, for example for JVC custom gamma (p.32).
AVI/VSI IF tab: Send or Disable AVI/VSI; advanced users only, wrong values can blank the screen (p.34–35).
To clear strings: hold RST 10 s or reset on the GUI CONFIG page (p.33).

01 / SIMPLE EXPLANATION

What is it?

The metadata travelling alongside the video.

AVI InfoFrames, VSIF and HDR metadata tell downstream equipment how aspects of the signal should be interpreted. Vertex can inspect/manipulate relevant metadata.

02 / REAL-WORLD USE

Why would you use it?

Useful for diagnostics, calibration and specialist HDR workflows.

In a Vertex system, this works together with the source, the connected sink(s), EDID/HDCP behaviour and the selected routing or processing configuration.

03 / HOW VERTEX USES IT

Inside the HDMI chain

Real-time HDR metadata injection/extraction plus AVI InfoFrame, VSIF and other InfoFrame manipulation.

SOURCE → VERTEX → DISPLAY / AVR / PROJECTOR

04 / IMPORTANT TO KNOW

Do not confuse this with…

Metadata is not the picture itself; it describes properties of the signal.

This page explains the term in the context of the documented Vertex specification rather than as a general claim about every HDMI device.

QUESTIONS PEOPLE ASK

Common questions

Why would I want to change HDR metadata?

Sometimes a display chooses the wrong mode or tone-mapping. With the Vertex you can inject your own HDR metadata, or cancel incoming HDR metadata so, for example, a JVC projector can use its own gamma curve (p.32).

Is changing InfoFrames risky?

It can be. The manual calls the AVI change an advanced-user feature: wrong values can blank the screen, and the setting survives power cycles until you undo or reset it (p.34–35).

Does the Vertex change the picture itself when I change metadata?

No. Metadata only describes the signal; the display decides what to do with it.
