... two bit allocations, that is, loop-representative bit allo- cation and maximum bit rate allocation, to obtain the ini- tial bit distribution, and then it performs multiple-bits load- ing for ... a mul- tistaged bit rate allocation scheme to meet the target rate. If the total bit rate is far from the target rate, a multiple-bits loading procedure is used to obtai...

... Results for p e = 0.05 for “Rena” video. results demonstrate the superiority of the proposed scheme compared to nonoptimized schemes. For low bit rates, the difference is not clear but for high bit rates ... encoder bit rates R I , R L ,andR R , and optimal parity ratios ρ I , ρ L , and ρ R for given p e and R C . The constraint ensures that the final bit rate satisfi...
