Abstract
The paper describes a simple quantitative model of AVC/ H.264 coders. The model defines the relationship between the bitstream and the quantization step (Qstep) for I- and P-frames. The whole allowed range of Qstep values has been divided into 3 intervals. In 1st and 3rd interval, the proposed model has only one parameter that depends on sequence content, whereas in 2nd interval the proposed model has three parameters that depend on sequence content. The experiments have been conducted on 4CIF sequences and showed that proposed model fits experimental data very well in all intervals.
