Configure the internally-generated video standards for both SDI

transmitters.

00 = SD-SDI: When 00, enables the embedding of audio group 1,

01 = HD-SDI: When 01, enables the embedding of audio group 1 and 2,

11 = 3G-SDI Level A: When 11, enables the embedding of audio group

1, 2, and 3,

10 = 3G-SDI Level B: When 10, enables the embedding of audio group

1, 2, 3, and 4

Running the Design Example

To run the design example, you must set up the development board.

To set up the development board, follow these steps:

1. Set up the board connections.

a. Connect the SDI HSMC to HSMA port on the Stratix IV GX development board.

b. Connect the development board to the power supply.

c. Connect the SDI_OUT_2 port (SDI TX P0) to the SDI_IN_1 port (SDI duplex) using external BNC

cable.

d. Connect the AES_OUT_1 port to the AES_IN_1 port using external BNC cable.

e. Connect the SDI_OUT_1 port (SDI duplex) to the external waveform monitor so that you can analyze

the embedded audio in the SDI video stream.

2. Launch the Quartus II software.

a. On the File menu, click Open Project, navigate to ip/altera/audio_ip/example/s4gx_sdi_audio/s4gxsdi_

audio.qpf, and click Open.

b. On the Processing menu, click Start Compilation.

3. Download the Quartus II-generated SRAM Object File (.sof).

After you set up the board, run the different configurations described in the following sections.
