Summary

Rec. ITU-T T.808 | ISO/IEC 15444-9 provides a network protocol that allows for the interactive and progressive transmission of JPEG 2000 coded data and files from a server to a client. The first edition of this Recommendation | International Standard dates to 2005. It has since then been supplemented by amendments and corrigenda. Additionally, other members of the JPEG 2000 family of Recommendations | International Standards, that are capable of being used with the network protocol described in this Recommendation | International Standard have since been introduced. This second edition incorporates the changes associated with these developments, without modifying the original scope.

This Recommendation was developed jointly with ISO/IEC JTC 1/SC 29/WG 1 (JPEG), and is common text with ISO/IEC 15444-9.

This second edition cancels and replaces the first edition, which has been technically revised.

The main changes compared to the previous edition are as follows:

1.     consolidates all outstanding amendments and corrigenda published since the first edition;

2.     extends support for the file format specified in Rec. ITU-T T.815 | ISO/IEC 15444-16;

3.     clarifies normative server responsibilities in response to certain request fields documented in Annex C;

4.     removes the registration authority (Annex L); and

5.     adds media type registration information (Annex O).

This Recommendation contains an electronic attachment that is available from the ITU website at: https://handle.itu.int/11.1002/2000/7460, and from the ISO website at: https://standards.iso.org/iso-iec/15444/-9\ed-2/en.
