`added to the pel[i][i] which were computed above using the motion vectors. The result of the addition shall be

`
`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 l-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 mismatch error, it is a requirement of bitstream conformance that each macroblock shall be intra-coded
`at least once within each series of 132 times that it is coded in a P-picture without an intervening l-picture. For
`purposes of counting the number of times a macroblock is coded in P-pictures, a skipped macroblock is not
`considered to be a coded macroblock.

`
`Annex A
`
`(normative)
`
`8 by 8 Inverse discrete cosine transform
`
`The 8 by 8 inverse discrete cosine transform for l-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 requirement for 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 lTU-T
`H.261 :1993.
`
`with:
`
`Annex A
`
`(normative)
`
`8 by 8 Inverse discrete cosine transform
`
`The 8 by 8 inverse discrete cosine transform (IDCT) approximation that is used in the decoding process for
`I-pictures and P-pictures shall conform to the accuracy requirements specified for conformance to
`ISO/IEC 23002-1. Passing the additional tests specified in lSO/IEC 23002-1 Annexes A and B is encouraged
`but not required.
`
`Note that for B-pictures the use of an integer approximation of the ideal 8 by 8 IDCT process is also
`necessary. and that the use of an lDCT approximation that conforms to the requirements specified in
`ISO/IEC 23002-1 may be beneficial. However. the accuracy requirements specified in ISO/IEC 23002-1 may
`be unnecessarily stringent for the decoding of B-pictures and are thus not required for the decoding of
`B-pictures in conformance to this International Standard.

`
`If macroblock_pattern is zero. cbp=0.
`
`3) Replace subclause 2.4.3.7 (page 30, line 25) by:
`
`The number of bits in the following dct_dc_dilferential code, dct_dc_size_luminance, is derived according to the VLC table
`3.53.
`
`4) Replace subclause 2.4.3. 7 (page 30, line 29) by:
`
`The number of bits in the following dct_dc_differemial code, dct_dc_size_chrominance, is derived according to the VLC table
`B.5b.
`
`5) Replace subclause 2.4.3.7 (page 30, line 32) by:
`
`If dct_dc_size_luminance or dct_dc_size_chrominance (as appropriate) is zero, then dct_dc_differential is not present in the
`bitstream.
`
`6) Replace subclause 2.4.3. 7 (page 30, line 35) by:
`
`If dct_dc_size_lutninance or dct_dc_size_chrominance [as appropriate) is greater than zero. then dcthlO] is computed as
`follows from dct_dc_diffcrential:

`
`7) Replace subclause 2.4.3.7 (page 30. line 37—43) by:
`
`For luminance blocks:
`
`if ( dct_dc_differential & ( l << (dct_dc_size_luminance-1)) ) dct_zz[0] = dct_dc_differential
`else dct_zz[0] = ( (-1) << (dct_dc_size_luminance) ) | (dct_dc_differential+l) ;

`
`For chrominance blocks:
`if ( dct,dc_differenlial & ( 1 << (dct_dc_size_chrominance-l)) ) dct_zz[0] = dct_dc_differential
`else dct_zz[0] = ( (-1) << (dct_dc_size__chrominance) ) l (dct_dc_differential+l) ;

`
`u
`example for dct_dc_size_luminance = 3
`
`9) Replace subclause 2.4.4.4 (page 38, lines 4-5) by:
`
`In B-pictures, the skipped macroblock is defined to have the same direction of prediction (forward, backward, or bidirectional)
`as the prior macroblock, differential motion vectors equal to zero, and no DCT coefficients.
`
`10) Replace subclause D. 6. 5.2 (page 99. line 39) by:
`
`Whereas in P-pictures skipped macroblocks have a motion vector equal to zero, in B—pictures skipped macroblocks have the
`same motion vector and the same direction of prediction (forward, backward, or bidirectional) as the previous macroblock,
`which cannot be inlra coded.
