Data Block:Alw
ays 200h for HD. If SD is present, this increments by 1
when consecutive data for each DID is present, or when data blocks within
a common data ID are to be linked.
Data Count: 10Bh for HD. For SD, the data count represents the number o f
user data words to follow, up to a m aximum of 255 words.
Field/Line:Showsthefield of the audio from which the packet was acquired.
The line of the audio (within the field) from which the packet was acquired.
Checksum: Shows the checksum word that was recovered from the acquired
packet.
Should be: Shows the checksum word computed b y the instrument, based on
the pa cket data.
Channel: Shows the specific channel(s) to which the Audio Frame, Rate
(kHz), Active Chan, and Delay Samples data apply. The AES stream allows
up to 16 channels of audio data, and every 4 channels are transmitted together
as an audio group.
Audio Frame: Audio frame (AF) number data provide a sequential
numbering of video frames that indicate where they fall in the progression of
the non-integer number of samples per video frame (audio frame sequence).
The fir
st number of the sequence is always 1 and the final number is equal to
the length of the audio frame sequence. An audio frame value of one or more
zeroes indicates that frame numbering is not available.
Rate (kHz): Shows the audio sampling rate.
Act
ive Chan: Shows whether the audio channel is active or inactive.
Delay Samples: Shows the amount of accumulated audio processing delay
re
lative to video, measured in audio sample intervals.
