# DeltaCast

Available in version **1.11.50+**.

OmniScope can capture live SDI video from supported **DeltaCast** cards on **macOS** and **Windows**. DeltaCast devices appear in the **Connect to...** dialog as:

* `DeltaCast: <model> (RX0)`
* `DeltaCast: <model> (RX1)`

Each RX channel is exposed as a separate input source, so multi-channel cards can provide more than one selectable input.

## Connect a DeltaCast source

1. Install the DeltaCast **VideoMaster** driver/runtime so the card is visible to the system.
2. Open **Input > Connect to...**
3. Find the **DeltaCast** section and select the required RX channel.

If OmniScope cannot see the VideoMaster API or no boards are available, the DeltaCast source will not appear in the source list.

## Source settings

DeltaCast inputs expose a small source-specific settings panel:

| Setting             | Description                                                                                |
| ------------------- | ------------------------------------------------------------------------------------------ |
| **Pixel Format**    | Choose **YUV 10-bit (V210)** or **YUV 8-bit (UYVY)**.                                      |
| **Queue Depth**     | Adjust the internal frame queue depth.                                                     |
| **Restart Capture** | Restarts the DeltaCast capture stream after changing settings or troubleshooting a signal. |

When the source is running, OmniScope also shows the detected signal format and the active capture format in the settings panel.

## Genlock

DeltaCast inputs can select a genlock source from the source settings:

* **Reference Input**
* **RX0**
* **RX1**
* **Local Clock**

The current genlock status, reference format, source, and measured offset can be shown in [Text Display](/nobe-omniscope/scopes/text-display.md).

## Text Display placeholders

Available in version **1.11.50+**.

DeltaCast inputs populate Text Display placeholders for:

* **Genlock** status, lock state, source, reference format, and offset
* **SDI RX signal health** including lock state, carrier presence, sync errors, ANC errors, CRC/EDH error state, and CRC line error count
