`to obtain the inverse transformed pel values in the range [-256, 255]. These pel values shall be limited to the

`Once the DCT coefficients are reconstructed, the inverse DCT transform defined in Annex A shall be applied
`to obtain the inverse transformed pel values in the range [-256, 255]. The inverse DCT pel values shall be
`addedto thepel[i][j]] which were computed above using the motion vectors. The result of the addition shall be

`Once the DCTcoefficients are reconstructed, the inverse DCT transform defined in Annex A shall be applied
`to obtain the inverse transformed pel values in the range [-256, 255]. The inverse DCT pel values shall be

`
`Replace subclause 2.4.4.5, “Forced updating’, which states as follows:
`
`This function is achieved by forcing the use of an intra-coded macroblock. The update pattern is not defined.
`For control of accumulation of IDCT mismatch error, each macroblock shall be intra-coded at least once per
`132 times it is coded in a P-picture without an intervening |-picture.
`with:
`
`This function is achieved by forcing the use of intra-coded macroblocks as a requirement for conformance of
`the bitstream. No particular pattern for intra macroblock coding is specified. For control of accumulation of
`IDCT mismatcherror, it is a requirementof bitstream conformance that each macroblock shall be intra-coded
`at least once within each series of 132 timesthatit is coded in a P-picture without an interveningI-picture. For
`purposes of counting the numberof times a macroblock is coded in P-pictures, a skipped macroblock is not
`considered to be a coded macroblock.

`
`Annex A
`
`(normative)
`
`8 by 6 Inverse discrete cosine transform
`
`The 8 by 8 inverse discrete cosine transform for |-pictures and P-pictures shall conform to IEEE Draft
`Standard, P1180/D2, July 18, 1990. For B-pictures this specification may also be applied but may be
`unnecessarily stringent. Note that clause 2.3 of P1180/D2 "Considerations of Specifying IDCT Mismatch
`Errors" requires the specification of periodic intra-coding in order to control the accumulation of mismatch
`errors. The maximum refresh period requirernentfor this part of ISO/IEC 11172 shall be as stated in 2.4.4.5,
`which is the same as indicated in P1180/D2 for visual telephony according to Recommendation ITU-T
`H.261:1993.
`
`with:
`
`Annex A
`
`(normative)
`
`8 by & Inverse discrete cosine transform
`
`The 8 by8 inverse discrete cosine transform (IDCT) approximation that is used in the decoding process for
`l-pictures and P-pictures shall conform to the accuracy requirements specified for conformance to
`ISONEC 23002-1. Passing the additional tests specified in ISOMEC 23002-1 Annexes A andBis encouraged
`but not required.
`
`Note that for B-pictures the use of an integer approximation of the ideal 8 by 8 IDCT processis also
`necessary, and that the use of an IDCT approximation that conforms to the requirements specified in
`ISO/EC 23002-1 may be beneficial. However, the accuracy requirements specified in ISOAEC 23002-1 may
`be unnecessarily stringent for the decoding of B-pictures and are thus not required for the decoding of
`B-pictures in conformanceto this International Standard.

`2) Replace subclause 2.4.3.6 (page 30, line 2) by:
`
`If macroblock_patternis zero, cbp=0.
`
`3) Replace subclause 2.4.3.7 (page 30, line 25) by:
`
`The numberofbits in the following det_dc_differential code, det_de_size_luminance, is derived according to the VLC table
`B.5a.

`
`The numberofbits in the following dct_dc_differential code, dct_dc_size_chrominance, is derived according to the VLC table
`B.5b.
`

`
`If det_dc_size_luminance or det_dc_size_chrominance (as appropriate)is zero, then det_dc_differential is not presentin the
`bitstream.
`
`6) Replace subclause 2.4.3.7 (page 30, line 35) by:
`
`If det_de_size_luminance or det_de_size_chrominance(as appropriate) is greater than zero, then dct_zz[0] is computed as

`
`For luminance blocks:
`

`9) Replace subclause 2.4.4.4 (page 38, lines 4-5) by:
`
`In B-pictures, the skipped macroblockis defined to have the samedirection of prediction (forward, backward,orbidirectional)
`as the prior macroblock,differential motion vectors equal to zero, and no DCTcoefficients.
`
`10) Replace subclause D.6.5.2 (page 99, line 39) by:
`
`Whereas in P-pictures skipped macroblocks have a motion vector equalto zero, in B-pictures skipped macroblocks have the
`same motion vector and the samedirection of prediction (forward, backward, or bidirectional) as the previous macroblock,
`which cannotbe intra coded.
