Table 4-23, Table 4-24, Table 4-25, and Table 4-26 show the audio sample distributions
for each of the four audio groups. Each distribution has 525 lines with either 1602 or
1601 samples based on the frame number of the five-frame sequence.
NOTE: When 1602 samples are required, the [4/3] term represents a line with 4 samples.
When 1601 samples are required, the [4/3] term represents a line with 3 samples.

4.7.22.2 625-line Audio Sample Distribution
The following sample distribution is for 625-line video standards which leaves more free
HANC space when inserting 16 channels (4 audio groups) of 24-bit sampled audio.
The sample distribution is established for group 1 and then offset by 1 line for each
subsequent group. The sample distribution is as follows (start line is 8):
[3](G-1),([4],[3]11)25,[4],[3](12-G),[0], [3](G-1),([4],[3]11)24,[4],[3](23-G),[0]
