JPEG-2000 Codestream Restrictions
JPEG-2000 codestreams must conform to ISO 15444-1:2004/PDAM 1 and more fully constrained as follows:
 All frames shall be untiled; the entire image shall be encoded as a single tile.
 The image and tile origins shall both be at <0,0>.
 Each compressed frame shall be less than 1,300,000 bytes.
 Each tile part of a compressed frame shall be less than 500,000 bytes.
 Compressed frames of 4:4:4 content shall have 3 tile parts.
Compressed frames of 4:2:2 content shall have 2 tile parts.
 The progression order shall be Component Position Resolution Layer (CPRL).
 All frames shall contain a Tile-part Length, Main header (TLM) marker.
 The following markers are forbidden:
o POC – Progress Order Change
o PPM – Packed Packet headers, Main header
o PPT – Packed Packet headers, Tile-part header
o RGN – Region of interest
 The following markers may appear only in the main header.
o COC – Coding style Component
o COD – Coding style Default
o QCC – Quantization Component
o QCD – Quantization Default
 Codeblocks shall be of size 32x32 for 4:4:4, 2K and 1080p resolutions.
Codeblocks shall be of size 128x32 for all other formats and resolutions.
 The codeblock coding style shall be SPcod, SPcoc = 0b00000000.
 The precinct sizes at all resolutions shall be 256x256, except the lowest frequency subband, which must
have a precinct size of 128x128
There must be no more than 5 wavelet transform levels.
