Figure 4-13: SD Extended Audio Data Packet Structure
For both audio data and extended audio packets, the Data Block Number is
embedded with a running sequence of 1 to 255.
4.7.8.2 HD Formats
Figure 4-14
shows the structure of the audio data packets as defined in SMPTE
299M. The audio data packets are multiplexed into the chroma channel of the video
data stream.
Table 4-7
lists the descriptions of the audio data packet words. The
audio core automatically generates certain audio data packet words, as shown in
Table 4-7
.
