Image encoding method and image encoding apparatus
An image encoding method of encoding units that are included in a picture is provided. The image encoding method generates a first flag which indicates whether or not a removal time of encoded data from a buffer by a hypothetical decoder is set per unit. The buffer is for storing the encoded data. The image encoding method further generates a second flag indicating whether an interval between removal times of the units is constant or arbitrary when the removal times are set per unit, and also generates an encoded bitstream which includes the encoded data, the first flag, and the second flag.
1. An image encoding method of encoding units that are included in a picture, the image encoding method comprising:
generating a first flag indicating whether or not a removal time of encoded data from a buffer by a hypothetical decoder is set per unit, the buffer being for storing the encoded data;
generating a second flag indicating whether an interval between removal times of the units is constant or arbitrary when the removal times are set per unit; and
generating an encoded bitstream including the encoded data, the first flag, and the second flag.
2. An image encoding apparatus for encoding units that are included in a picture, the image encoding apparatus comprising:
control circuitry; and
a storage accessible from the control circuitry,
wherein the control circuitry executes:
generating a first flag indicating whether or not a removal time of encoded data from a buffer by a hypothetical decoder is set per unit, the buffer being for storing the encoded data;
generating a second flag indicating whether an interval between removal times of the units is constant or arbitrary when the removal times are set per unit; and
generating an encoded bitstream including the encoded data, the first flag, and the second flag.
