Compliance points (Cpoint) for MJPEG2000

From: "Part 3 draft Amendment 3, Definition of compliance classes and testing for Motion JPEG2000" (see below.)

	Quarter Screen	Standard Video	HDTV Video	Digital Cinema
Cpoint-x	0	1	2	3
Height up to	288	576	1080	3112
Width up to	360	720	1920	4096
Depth up to	8	12	12	16
Subsampling	4:2:0	4:2:0	4:2:2	4:4:4
Components up to	3	3	4	4
Kernels	9-7(5-3)	9-7	9-7	9-7
Levels	3	4	5	5
Layers up to	15	15	15	15
Bytes per component up to	0.5	0.75	0.75	1
Bits per pixel up to	6	9	12	24
Frame size in bytes up to	77,760	466,560	3,110,400	38,240,256

"Depth" in bits, is per color-space component, of which 3 is typical.

"Levels"is the minimum number of transform levels a compliant decoder will guarantee to process, so one might consider this a maximum when encoding.

A Cpoint-3 decoder is the most capable and ideally best performing.
