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 1st 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 2nd 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 has an electronic attachment that can be found in the SG16 IFA at https://www.itu.int/ifa/t/2022/sg16/exchange/wp3/q06/Refs/T.808_15444-9-Ed2_JPIP_testing_package.zip.
After approval, this attachment will be available in the ITU website at: https://www.itu.int/net/ITU-T/sigdb/speimage/Tseries-s.htm#T.808.
