JVET-AM0247 Non-EE2: Extension of AMVP MVP Index Range [T. M. Bae, S. Deshpande (Sharp)] [late]
This contribution proposes:
- Extending the MVP index range in AMVP uni-directional prediction.
- A new signalling method for MVP index to reduce the signalling overhead
On top of ECM-17.0, simulation results of the proposed method are as follows:
LDB: -0.04% (Y), 0.06% (U), 0.26%(V), EncT: %, DecT: %.
RA: <To be completed>
Simulation results (1 bitstream of class B is copied from anchor, EncT/Dec T are not accurate)

Class TGM | #VALUE! | #VALUE! | #VALUE! | #DIV/0! | #DIV/0! | #DIV/0! | #DIV/0! |
Further study to see benefit for RA, unbalanced benefit over classes in LB. Changing AMVP signalling different for RA and LB would be undesirable. Better understanding and more information is requested if additional processing/checks are necessary at encoder.
