Hence, the number of bit assigned to ϕ11 should be a function of r1 and r2, which is in turn related to the value of ψ21 when GR is in use.
The quantity of these intervals is determined by the corresponding number of bits assigned by the bit allocation algorithm.
For the so-called bit allocation, the maximum number of bits assigned to each normalized transform coefficient is set to Rmax = 9 in G.719 by default.
They can be summarized as follows in the format of (b ψ b ϕ ), namely (1,3), (2,4), (3,5), and (4,6), where b ψ represents the number of bits assigned to ψ, and b ϕ represents the number of bits assigned to ϕ. Parameter ψ has a range from 0 to π/2 whereas ϕ spans over a range from 0 to 2π [1, 4].
The blue bars represent the number of bits assigned to the amplitude values, the red bars represent the number of bits assigned to the phase values, and the dashed black line represents the total number of bits assigned to each frequency band.
The blue bars represent the number of bits assigned to the amplitude values (B Ak ), the red bars represent the number of bits assigned to the phase values (B Pk ), and the dashed black line the total number of bits assigned to each frequency band (B Ak +B Pk ).
It should be noted that the number of bits assigned to the I frame in a GOP is very important.
where B ik is the total number of bits assigned to user i during k time slots.
The number of bits assigned to each subband is calculated using a rate estimation algorithm (Section 5.2) aiming for a specific distortion.
If q b represents the number of bits assigned to Q b , then s b Q will have elements in {0,1,…,L b - 1}, where L b = 2 q b.
