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.
Web1 de out. de 2010 · This article presents a rate control algorithm for hierarchical B -frames in H.264/AVC. Taking the feature of the dyadic hierarchical coding structure into consideration, the proposed algorithm includes group of pictures (GOP) layer, temporal layer and frame layer bits allocation. After frame layer bits allocation is complete, frame … Web28 de jan. de 2014 · Generally, H.264/AVC video coding standard with hierarchical bipredictive picture (HBP) structure outperforms the classical prediction structures such …
WebWe derive an efficient rate allocation for hierarchical B-pictures using the power spectral density of a wide-sense stationary process. In addition, we discuss important aspects of hierarchical predictive coding, such as the effect of the temporal prediction distance and delay tradeoffs for prediction branch truncation.
Webhierarchical B picture coding stru ctures, as will be explained below. As shown in Sec. 2, hierarchical B picture structures have very straightforward t ree-like dependency structures introduced by MCP, since the impact of any B picture is limited to other B pictures in higher temporal stages ( sub-trees ) of the same GOP. how do you write 45 billionWebthe hierarchical-B coding structure is well-known for random access applications, the hierarchical-P structure is more appropriate for low delay cases. The pros and cons of the hierarchical-P structure are well presented in Reference [14].
