ADV601LC

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.
