Connecting the SDI Video Output

Refer to Figure 2.1.

• 4:4:4/4:2:2:4/4:4:4:4 dual-link signals are sent to the Fill Out and Key Out BNC connectors (fill + key signals are sent to the corresponding BNC connectors).

• 4:2:2 single-link signals are sent to the Fill Out BNC connector only.

In application control mode, using the APIs, an additional 4:2:2 signal can be sent to the Key Out BNC connector.

Connecting to an External Sync Source

• You can genlock the output to an external digital or analog sync source.

NVIDIA Genlock supports the following two external synchronization signal types:

• SDI

• Composite, which can be one of

Composite Bi-level (NTSC or PAL sources use bi-level composite signals.)

HAPTER 2

NVIDIA Graphics-to-SDI

Composite Tri-level (HDTV sources commonly use tri-level composite signals.)

• To use an external sync source, connect the sync signal to the appropriate BNC connector as indicated in Figure 2.1.

You can connect to both types of sync sources at the same time. The software gives precedence to the SDI signal, but you can use the control panel to choose which signal to use (see “Synchronizing the SDI Output to an External Source” on page 19.)

Software Setup

The NVIDIA SDI software lets you specify the

•SDI signal format

• Color formats

• Synchronization method

• Gamma correction

Graphics-to-SDI functionality can be set up and controlled in two basic ways—using the NVIDIA control panel or using the NVIDIA SDI API.

Using the SDI APIs

The SDI application programming interface allows OpenGL applications to have full and exclusive control of the SDI output. This is also known as extended mode.

When the SDI output is under application control, you can use the NVIDIA Graphics to SDI property page to view the SDI hardware status.

• See the chapter “API Control” on page 23 for a description of the graphics-to-video-out API calls.

• Also, refer to the document instructions on using the API.

Using the Control Panel

When the SDI output is not being controlled by an application, you can use the NVIDIA Graphics to SDI property page to

• Specify the SDI signal format, output format, and then enable the SDI output.

• Configure the external synchronization signal if needed.

This is also known as transparent mode. In this mode, the SDI software work on top of existing applications, and the active workstation desktop or full screen application display is automatically forwarded to the SDI video outputs.

See the chapter “Using the Graphics to SDI Control Panel” on page 11 for detailed instructions on using the Graphics to SDI property page.

Recommended Operating Practices

This section provides some basic operating practices to follow in order to obtain the best SDI performance for your application.

Initial On-Air Broadcast

When starting a live broadcast of SDI video, follow the sequence below to ensure proper allocation of system resources and to prevent visual disturbances in the on air broadcast.

1 Set up the SDI format settings and start the SDI output

2 Start the application to be broadcast

3 Verify the video quality

4 Close the Graphics to SDI control panel

HAPTER 2

NVIDIA Graphics-to-SDI

5 Go on air

To avoid visual disturbances while broadcasting live, DO NOT

• Start or stop the graphics or video application

• Turn on or off the SDI output

• Make changes to the SDI signal format

Changing Applications

To avoid visual disturbances while switching applications, observe the following sequence:

1 Stop the live broadcast (go off air)

2 Stop the application

3 Start the new application

4 Verify video quality

5 Resume the live broadcast

NVIDIA Corporation Quadro FX 4000 SDI User’s Guide – Version 2.1 9

HAPTER 2

C NVIDIA Graphics-to-SDI

Changing Video Formats

When changing any of the SDI settings, visual disturbances might occur as the video resets to the new settings. To prevent such disturbances from being visible to the public or from being recorded, observe the following sequence when making changes to any SDI setting:

1 Stop the live broadcast (go off air)

2 Change video format or SDI settings

3 Verify video quality

4 Resume the live broadcast

When Using the Control Panel

NVIDIA recommends the following

• Set the desktop to the same or higher resolution than the SDI output for better image quality.

• Close all background applications—such as virus scan, backup, and archiving applications—before starting the SDI output and going on air.

• Close the Display Properties panel before going on air.

• When running multiple OpenGL applications, tearing may occur if the applications are not synchronized.

In general, NVIDIA does not recommend running multiple OpenGL applications when starting the SDI output or when going live.

Running Multiple OpenGL Applications

To maximize the system resources and bandwidth available for converting graphics to SDI output, NVIDIA recommends broadcasting only one OpenGL application at a time.

Using the Graphics to SDI Control Panel

Synchronizing the SDI Output to an External Source

You can synchronize the SDI output with other equipment in a broadcast or post production environment.

Genlock Versus Frame Lock

The Graphics to SDI page provides two methods for synchronizing the SDI output to a common sync source—Genlock and Frame lock.

Using Genlock

Genlock synchronizes the pixel scanning of the SDI output to an external synchronization source.

When using genlock, the SDI refresh rate is determined by the sync source, so any refresh rates that you may have chosen in the SDI signal format list do not apply.

HAPTER 3

Using Frame Lock

Frame lock synchronizes the frame rate of the SDI output to an external synchronization source.

When using frame lock, only modes that are valid for the frame rate of the sync source can be used for the SDI output. The valid modes will appear in the SDI signal format list.

Supported Synchronization Signals

NVIDIA Genlock supports the following external synchronization signal types:

•SDI

• Composite Bi-level (NTSC or PAL sources use bi-level composite signals.)

• Composite Tri-level (HDTV sources commonly use tri-level composite signals.)
