20 Claims

1. A method comprising:

estimating an occupancy level of a coded picture buffer (CPB) associated with a hypothetical reference decoder (HRD) based on an upper limit for bit allocation;

allocating a first number of bits for encoding a first picture based on the estimated occupancy level of the CPB;

selecting a quantization parameter value based on the allocated number of bits; and

encoding the first picture based on the selected quantization parameter value;

wherein the upper limit is estimated based on a second number of bits to be allocated for encoding a second picture; and

wherein the second number of bits is based on:

a removal time of an access unit from the CPB; and

a time of arrival of a first bit of the access unit at the CPB.
