Title:
CODING DEVICE, DECODING DEVICE, CODING METHOD AND DECODING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/031369
Kind Code:
A1
Abstract:
A coding device (100) is provided with a circuit (160) and a memory (162), wherein the circuit (160) uses the memory (162) to determine, on the basis of first information related to processing time at the time of decoding, whether FRUC processing is prohibited or not (S201), when determining that the FRUC processing is prohibited (Yes in S201), selects one prediction mode from multiple prediction modes not including the FRUC processing (S203), and performs coding without using the FRUC processing (S206), and when determining that the FRUC processing is not prohibited (No in S201), selects one prediction mode from multiple prediction modes including the FRUC processing (S202), using the FRUC processing (S205) or without using the FRUC processing, performs coding (S206), and generates a coded bit stream including second information indicating whether the FRUC processing is used or not (S207).
