Publication number: 20250030893Abstract: Provided is an apparatus and method for encoding/decoding a moving picture based on adaptive scanning. The moving picture apparatus and method can increase a compression rate based on adaptive scanning by performing intra prediction onto blocks of a predetermined size, and scanning coefficients acquired from Discrete Cosine Transform (DCT) of a residue signal and quantization differently according to the intra prediction mode. The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.Type: ApplicationFiled: October 4, 2024Publication date: January 23, 2025Applicant: Electronics and Telecommunications Research InstituteInventors: Jeong-Il SEO, Wook-Joong KIM, Kyu-Heon KIM, Kyeong-Ok KANG, Jin-Woo HONG, Yung-Lyul LEE, Ki-Hun HAN, Jae-Ho HUR, Dong-Gyu SIM, Seoung-Jun OH
