Quality Scalability Compression on Single-Loop Solution in HEVC

Abstract EN

This paper proposes a quality scalable extension design for the upcoming high efficiency video coding (HEVC) standard.

In the proposed design, the single-loop decoder solution is extended into the proposed scalable scenario.

A novel interlayer intra/interprediction is added to reduce the amount of bits representation by exploiting the correlation between coding layers.

The experimental results indicate that the average Bjøntegaard delta rate decrease of 20.50% can be gained compared with the simulcast encoding.

The proposed technique achieved 47.98% Bjøntegaard delta rate reduction compared with the scalable video coding extension of the H.264/AVC.

Consequently, significant rate savings confirm that the proposed method achieves better performance.
