Publication number: 20240223793Abstract: An encoder that includes memory and circuitry coupled to the memory. The circuitry encodes a slice into one or more data access regions in a variable length encoding process. The circuitry encodes one or more offsets into a slice header, based on a flag written into a sequence header and a total number of the one or more data access regions. The one or more offsets each specify a head position of a corresponding one of the one or more data access regions in a bitstream. When the flag indicates that the one or more offsets are to be encoded and the total number is at least two, the one or more offsets are encoded. The flag switches between encoding and not encoding the one or more offsets regardless of whether the total number is at least two.Type: ApplicationFiled: February 12, 2024Publication date: July 4, 2024Inventors: Kiyofumi ABE, Takahiro NISHI, Tadamasa TOMA, Yusuke KATO
