METHOD AND DEVICE FOR ENCODING/DECODING VIDEO SIGNAL USING SECONDARY TRANSFORM

摘要

Disclosed are a method and an apparatus for encoding/decoding a video signal. Specifically, a method for decoding a video signal may include: generating a quantized transform block by performing entropy decoding for the video signal; generating a dequantized transform block by performing dequantization for the quantized transform block; determining whether to apply secondary inverse transform based on information related to a non-zero coefficient in the dequantized transform block; and performing the secondary inverse transform for the dequantized transform block by using a secondary inverse transform kernel applied to the dequantized transform block.
