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_embed/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.
Transmit SD-SDI with Embedding of Audio Group 1
To transmit the SD-SDI video standard, follow these steps:
1. Set DIP switch[2:1] = 00
2. The demonstration runs and the LEDs indicate the following conditions:
a. LED D16 blinks indicating the heartbeat of the receiver's recovered clock.
b. LED D17 illuminates when the receiver is frame locked.
c. LED D18 illuminates when the receiver is TRS locked.
d. LED D19 illuminates when the receiver is alignment locked.
e. LED D23 illuminates when the data packet of audio group 1 is detected in the
incoming SDI stream.
Figure 4–11 shows the condition of the LEDs.
