Title:
ENCODING DEVICE, DECODING DEVICE, ENCODING METHOD, AND DECODING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/049644
Kind Code:
A1
Abstract:
An encoding device (100) is provided with a circuit (a1) and a memory (a2) connected to the circuit (a1). The circuit (a1) in operation encodes, for each temporal sub-layer, a Hypothetical Reference Decoder (HRD) parameter comprising one or more parameters of an HRD relating to a decoding unit, into an HRD-related Supplemental Enhancement Information (SEI) message, which is an SEI message relating to the HRD.
