Sign hiding techniques for quantized transform coefficients in video coding
This disclosure proposes techniques for encoding and decoding transform coefficients in a video coding process. In particular, this disclosure proposes techniques determining whether or not to apply a sign data hiding process for a group of transform coefficients, and techniques for applying the sign data hiding process. In one example, this disclosure describes a method for decoding video data comprising determining a block of transform coefficients, determining whether to perform a sign data hiding process for at least one transform coefficient in the block of transform coefficients based on a single variable compared to a threshold, and decoding sign information for the block based on the determination of whether to perform the sign data hiding process.
