ADV601LC
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.
