Abstract

An image decoding device is equipped with a header information decoding means for decoding profile/level information included in a video parameter set after decoding byte-aligned 16-bit extension information (next_essential_info_byte_offset) in the video parameter set.

Claims (20)

1. An image decoding device which decodes coded data obtained by coding image information, the image decoding device comprising:

a processor; and

a memory connected to the processor, wherein

the processor receives a video parameter set,

the processor decodes information for extension, having a code length of 16bits, in the video parameter set, and

thereafter receives profile/level information included in the video parameter set,

the processor decodes sublayer profile present flags, included in the profile/level information, indicating the presence or absence of sublayer profile information regarding respective sublayers,

the processor decodes byte-aligned data, included in the profile/level information, determined based on the number of the sublayers, and

the processor decodes each of the sublayer profile information, included in the profile/level information, regarding the respective sublayers when each of the sublayer profile present flags of the respective sublayers is equal to 1,

a first bit of the profile/level information is byte-aligned by the information for extension, and

a first bit of the sublayer profile information is byte-aligned by the byte-aligned data.

2. An image decoding method for decoding coded data obtained by coding image information, the image decoding method comprising:

receiving a video parameter set,

decoding information for extension, having a code length of 16bits, in the video parameter set, and

thereafter receiving profile/level information included in the video parameter set,

decoding sublayer profile present flags, included in the profile/level information, indicating the presence or absence of sublayer profile information regarding respective sublayers,

decoding byte-aligned data, included in the profile/level information, determined based on the number of the sublayers, and

decoding each of the sublayer profile information, included in the profile/level information, regarding the respective sublayers when each of the sublayer profile present flags of the respective sublayers is equal to 1,

a first bit of the profile/level information is byte-aligned by the information for extension, and

a first bit of the sublayer profile information is byte-aligned by the byte-aligned data.
