WebThe hierarchical B GOP structure includes a plurality of B pictures between an I picture and a P picture or between two P pictures. The multiple B-pictures are organized in a hierarchical structure. For example, for a hierarchical B GOP with a GOP length of 8, the GOP may consist of I 0, b 1, B 2, b 3, B 4, b 5, B 6, b 7, P 8,. Web1 de jul. de 2007 · Both hierarchical B-pictures and pulsed-quality coders involve uneven bit-rate allocation. Both the encoder and decoder buffering requirements depend on the rate allocation. We derive an efficient rate allocation for hierarchical B-pictures using the power spectral density of a wide-sense stationary process.
