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