Figure 11. Hierarchical Structure of Wavelet Compressed Frame Data (Data Block Order)

Compressed Data-Stream Definition

Through its Host Interface the ADV601LC outputs (during

encode) and receives (during decode) compressed digital video

data. This stream of data passing between the ADV601LC and

the host is hierarchically structured and broken up into blocks of

data as shown in Figure 11. Table IV shows pseudo code for a

video data transfer that matches the transfer order shown in

Figure 11 and uses the code names shown in Table XIV. The

blocks of data listed in Figure 11 correspond to wavelet com-

pressed sections of each field illustrated in Figure 12 as a modified

Mallat diagram.
