In general, a Frame of data is made up of odd and even Fields as
shown in Figure 11. 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 Sequence.
The Complete Block Sequence contains the remaining 41 Block
Sequences (see block numbering in Figure 12). Each Block

Sequence contains a start of block delimiter, Bin Width for the
block and actual encoder data for the block. A pseudo code bit
stream example for one complete field of video is shown in
Table XIII. A pseudo code bit stream example for one sequence
of fields is shown in Table XIV. An example listing of a field of
video in ADV601LC bitstream format appears in Table XVI.
