Figure 14. Block Order of Wavelet Compressed Field Data (Modified Mallat Diagram)
In general, a Frame of data is made up of odd and even Fields
as shown in Figure 13. Each Field Sequence is made up of a
First Block Sequence and a Complete Block Sequence. The
First Block Sequence is separate from the Complete Block Se-
quence. The Complete Block Sequence contains the remaining
41 Block Sequences (see block numbering in Figure 14). Each
Block Sequence contains a start of block delimiter, Bin Width
for the block and actual encoder data for the block. A pseudo
code bitstream example for one complete field of video is shown in
Table XIII. A pseudo code bitstream example for one sequence
of fields is shown in Table XIV. An example listing of a field
of video in ADV611/ADV612 bitstream format appears in
Table XVII.
