Altera SDI Audio IP Cores - Manual (Page 42)

SDI Transmitter P0
The triple-standard SDI transmitter that outputs a 3G-SDI (2.970 Gbps), HD-SDI (1.485 Mbps), or SD-SDI
(270 Mbps) data stream. This transmitter gets the parallel data source from the SDI Audio Embed IP core.
The SDI Audio Embed component embeds the internally generated audio in AES format into the internally
generated video. The transmitter transmits the serial signal through a BNC cable to the receiver of the SDI
duplex instance.
SDI Duplex
The triple-standard SDI duplex provides a full-duplex SD-SDI, HD-SDI, and 3G-SDI standards. The SDI
duplex instance routes the received data to the SDI Audio Extract IP core to extract the AES audio. The SDI
Audio Embed IP core embeds the internally generated audio in AES format into the internally generated
video. The transmitter in this duplex connects its output to the external waveform monitor, such as the
WFM700.
Audio Extract
The Audio Extract IP core extracts the embedded AES audio from the SDI stream. The Audio Extract IP
core routes the extracted AES audio to the AES output of the daughter card.
AES Input Module
The AES input module converts the AES signal to
aud_de
,
aud_ws
, and
aud_data
(internal AES) signals to
interface with Audio Embed P1. When this module interfaces with the Audio Embed IP core, both must use
the same clock.
AES Output Module
The AES output module converts the
aud_de
,
aud_ws
, and
aud_data
signals to AES signal. This module
configures the extracted internal AES audio signal (
aud_data
) without the biphase mark encoding. When
this module interfaces with the Audio Extract IP core, it must use the same clock as the Audio Extract IP
core.
Audio Embed P0/P1
The Audio Embed P0 embeds the AES audio generated by the Audio Pattern Generator into the video stream,
as a transmitting data, for the SDI transmitter P0. The Audio Embed P1 embeds the AES audio from the
external AES input into the video stream for the SDI duplex
Video Pattern Generator P0/P1
You can configure the internal video pattern generator to output an SD-SDI, HD-SDI, 3G-SDI Level A or
3G-SDI Level B colorbar pattern.
Audio Pattern Generator
You can configure the internal audio pattern generator to create an AES audio test sample that comprises
an increasing count. You configure the generator using the 48-kHz clock output from the Audio Embed IP
core.
Ancillary Data Insertion P0/P1
The Ancillary Data Insertion module inserts the ancillary data defined by SMPTE352 into the SDI video
stream.
