Two-level sliding-window VBR control algorithm for video on demand streaming

作者：

Highlights：

• A VBR controller for hierarchical video coding is proposed.

• The algorithm is specifically tailored for the HEVC standard.

• A sliding-window strategy aims at smoothing the bit resource allocation.

• This long-term bit allocation approach involves the reduction of PSNR fluctuations.

• Good PSNR consistency is especially achieved in few minutes long sequences.
