JCTVC-J0208 AHG5: Bypass bins grouping on Intra mode coding [H. Sasai, K. Terada, T. Nishi (Panasonic)]

This contribution presents a modification on intra mode coding parameters. It is proposed that the signalling order changes to improve the throughput of entropy coder by grouping bypass-coded bins. The proposed solution was implemented in HM7.0 and their coding efficiencies were evaluated. The results show no difference on coding performance.

Q: How large is the benefit in terms of hardware throughput? Is this syntax element critical? Most likely not.

Software implementation would become slightly more complicated due to the additional grouping.

No action.
