The Codec Working Group of Alliance for Open Media is working on creating next-generation royalty-free video coding technology beyond AV1. This paper proposes a parity hiding method to optimize the coefficients coding of transform block. The parity of quantization level at top-left position may be derived with information of other non-zero quantization levels within the same transform block. As a result, the quantization level at top-left position with hidden parity may be coded with half of its level. The proposed method has been implemented on top of a recent release of AOM reference software. Experimental results show that the proposed approach brings 0.26%/0.87%/0.85% BD-rate saving for all-intra test and 0.29%/0.70%/0.46% BD-rate saving for random-access test for Y/U/V components with marginal encoding and decoding time changes.
