Abstract
This contribution proposes to combine the contributions presented in JVET-O0569 and JVET-O0472. The proposed change involves: (1) moving Low-frequency Non-Separable Transform (LFNST) index signaling from CU level to TU level as proposed in JVET-O0569, and (2) using a last position-based rule as proposed in JVET-O0472 to decide on LFNST signalling. Simulations show that LFNST can be moved to TU level and the last position-based LFNST signaling can be simultaneously performed at the TU level with negligible losses/gains.
