Appeal No. 1999-1793
Application 08/161,798
determination of available frequency-units is based on psychoacoustic
criteria. The number of blocks (p;m) in the allocation window having
C(p;m)="1" is the count of available frequency-units. However,
Veldhuis does not disclose "counting" the available blocks (p;n).
Therefore, Veldhuis does not disclose "a step for counting a number
of available frequency-units by using the representative, based on
psychoacoustic criteria" (emphasis added).
Claim 5 recites "a first bit allocation step for determining an
initial bit allocation for each of said available frequency-units by
using an approximate mathematical model using said counted number of
available frequency-units." The blocks (p;m) in the allocation
window having C(p;m)="1" are the "available frequency-units." All of
the blocks are initially allocated a minimum number of bits B(p;m) as
a default value for the allocation pattern (e.g., col. 13, lines 60-
64; col. 21, lines 35-37) and then those blocks (p;m) with C(p;m)="0"
are set to B(p;m)=0 to produce sum S of "saved" number of bits
(col. 13, line 68 to col. 14, line 12), leaving the initial
allocations in blocks (p;m) with C(p;m)="1". This is a first bit
allocation step for each available frequency-unit. However, this
initial bit allocation is not disclosed or suggested to be made
"using an approximate mathematical model using said counted number of
