# Understanding NDI Formats

NDI allows manufacturers and developers to integrate support for different **NDI** **Formats** into their products. The formats correspond to various specifications, including supported codecs, bandwidth usage, and glass-to-glass latency.\
\
While **any NDI integration should guarantee the most fundamental interoperability aspects**, it is usually relevant to communicate and share technical details regarding the NDI formats your products support, as this will facilitate the user's experience when connecting through NDI. 

**Currently, there are three NDI Formats available to integrate.** Click the cards to access detailed instructions and recommendations that are crafted to optimize your communication and design approach when referring to**:**

Sending (encoding) NDI streams in NDI HX2 and NDI HX3 is exclusive to products licensing and integrating [**NDI Advanced**](https://ndi.video/for-developers/ndi-advanced/).

## Referring to NDI formats

{% hint style="danger" %}
The only correct way to refer to these is **formats**. Variations like "flavors," "types," and "codecs" are technically inaccurate and can lead to misinterpretation from the user's perspective.
{% endhint %}

Here is how you **can** mention support for a specific NDI Format (we are using NDI HX3 as an example):

* "Our product encodes/decodes/sends/receives/supports NDI HX3."
* "Our product encodes/decodes/sends/receives/supports the NDI HX3 format."
* "Product XYZ is certified for NDI HX3." (in case your product is [NDI Certified](https://ndi.video/ndi-certified/).)

Note that formats should always include **NDI** before the specific format nomenclature. You should **not** add other specs directly to the format (e.g., NDI HX3 4K60p), instead phrasing it like (we are using NDI HX3 as an example):&#x20;

* "Product XYZ can stream in 4K60p through NDI HX3."
* Product XYZ supports NDI HX3 in 4K60p."
* “Our device supports NDI HX3, enabling you to send 4K60p video with minimal latency and less bitrate.”
