ITU-T T.808 (2005) Amd. 2 (08/2007)

JPIP扩展

本修正案为JPIP增加了多成份转换清晰度水平标志。这对于在分量方向的次清晰度水平上通过小波多分量转换进行压缩的图像的远程浏览是十分益的。批准本修正案后，ISO/IEC JTC 1/SC 29也在制定ITU-T T.808建议书（2005年）| ISO/IEC 15444-9:2005的第2修正案，但目前尚未进行到FDAM阶段，因此，还不能考虑提交AAP。由于对ITU-T T.808建议书| ISO/IEC 15444-9的有关“JPIP扩充”的修正案作是为PDAM 3、FPDAM 3、FDAM 3由ISO/IEC JTC 1/SC 29进行的投票，因此为进行ITU-T的批准，作为第3修正案予以了保留，尽管第2修正案既未获得批准也未提供按照AAP方式审议。批准之后，为了保持已获批准的建议书|国际标准的临时编号方式，本修正案重新编号为第2修正案出版。
