GS1582 Data Sheet
40117 - 1 November 2007
39 of 114
4.7.4 Audio Packet Delete
Ancillary data packets with non-audio data ID words, such as arbitrary, EDH, SDTI
header and SMPTE 352M, will not be deleted from the data stream. On lines where
SMPTE 352M or SDTI header packets exist, the audio data packets must be
contiguous to the 352M and SDTI packets in SD mode. For HD formats, the audio
data packets must always be contiguous after the two EAV CRC words. If this is
not the case, all existing audio data and control packets will be deleted.
When the EN_CASCADE host interface bit is set HIGH, all existing audio data and
control packets will remain in the video stream.
When the AGR bit in the host interface is set HIGH, audio group replacement mode
is selected. In this mode, existing audio data and control packets will not be deleted
from the data stream with the exception of any packets of groups being replaced.
In cases where the ADF is not placed immediately after the CRC or EAV words, or
there are gaps between the packets, the audio core will delete all existing audio
data and control packets, regardless of the EN_CASCADE or AGR setting.
Figure 4-11
shows an example of correct and incorrect placement of ancillary data
packets for a SD format.
