INFORMATION TECHNOLOGY – JPEG 2000 IMAGE CODING SYSTEM –
PART 1: CORE CODING SYSTEM
TECHNICAL CORRIGENDUM 1
1) In the List of Figures (p. viii, Figure I-12) change
“Channel Definition box”
to
“Component Mapping box”
2) In subclause A.1.3 (p. 14), add to the end of the list of rules
— Some marker segments have values assigned to groups of bits within a parameter. In some cases there
are bits, denoted by “x,” that are not assigned a value for any field within a parameter. The codestream
shall contain a value of zero for all such bits. The decoder shall ignore these bits.
3) In subclause A.5.1 (p. 26, Ssiz description) change
(Ssiz AND 0x7F)-1 (Ssiz AND 0x7F)-1
“-2 ≤ component sample value ≤ 2 - 1”
to
(Ssiz+1 AND 0x7F)-1 (Ssiz+1 AND 0x7F)-1
“-2 ≤ component sample value ≤ 2 - 1”
4) In subclause A.6.1 (Table A-13, p. 30, seventh row) change
“EPH marker may be used”
to
“EPH marker shall be used”
5) In subclause A6.6 (Table A-32, p. 43, sixth and seventh row) change
i
16 0 — 65 534
LYEpoc
i i
8
REpoc RSpoc — 33
to
i
16 1 — 65 535
LYEpoc
i i
8
REpoc (RSpoc + 1) — 33
6) In subclause A.6.6 (Table A-32, p. 43, eighth row, CEpoc value) change
i
“CSpoc — 255; if Csiz < 257
i
CSpoc — 16 383; Csiz ≥ 257”
to
i
“(CSpoc + 1) — 255, 0; if Csiz < 257
i
(CSpoc + 1) — 16 384; Csiz ≥ 257
(0 is interpreted as 256)”

7) In subclause A.8.2 (p. 53, Usage first and second paragraph) change
“Usage: Optionally used in the bit stream or in the PPM or PPT marker segments. Shall only be used if indicated in
the proper COD marker segment (see Annex A.6.1). Appears immediately after a packet header.
If EPH markers are allowed (by signalling in the COD marker segment, see Annex A.6.1), each packet header in any
given tile-part may or may not be postpended with an EPH marker segment (see Annex A.8.1). If the packet headers
are moved to a PPM or PPT marker segments (see Annex A.7.4 and Annex A.7.5), then the EPH markers may appear
after the packet headers in the PPM or PPT marker segments.”
to
“Usage: Shall be used if and only if indicated in the proper COD marker segment (see Annex A.6.1). Appears
immediately after a packet header.
If EPH markers are required (by signalling in the COD marker segment, see Annex A.6.1), each packet header in any
given tile-part shall be postpended with an EPH marker segment. If the packet headers are moved to a PPM or PPT
marker segments (see Annex A.7.4 and Annex A.7.5), then the EPH markers shall appear after the packet headers in
the PPM or PPT marker segments.”
8) In subclause B.6 (Equation B.16, p. 64) change

---------- ---------- ---------- ----------
PPx- PPx- PPy- PPy-

and add to the beginning of the next paragraph
“Even if Equation B.16 indicates that both numprecinctswide and numprecinctshigh are nonzero, some, or all,
precincts may still be empty as explained below.”
9) In subclause B.11 (p. 74, sixth paragraph) change
“If EPH markers are allowed (by signalling in the COD marker segment, see Annex A.6.1), each packet header in any
given tile-part may be postpended with an EPH marker segment (see Annex A.8.1). If the packet headers are moved to
a PPM or PPT marker segments (see Annex A.7.4 and Annex A.7.5), then the EPH markers may appear after the
packet headers in the PPM or PPT marker segments.”

“If EPH markers are required (by signalling in the COD marker segment, see Annex A.6.1), each packet header in any

PPM or PPT marker segments (see Annex A.7.4 and Annex A.7.5), then the EPH markers shall appear after the packet
headers in the PPM or PPT marker segments.”
10)In subclause B.12.1.3 (p. 76, fifth equation) change
PPy()r, i + N – r
L
“if (y = ty or y divisible by YRsiz()i ⋅ 2 )”
