11、H.222.0 (2017) | ISO/IEC 13818-1:2017 fixes interoperability issues in the transport of JPEG 2000 Part 1 (Rec. ITU-T T.800 | ISO/IEC 15444-1) by removing references to Rec. ITU-T T.800 | ISO/IEC 15444-1 Annex M and updating the definition of the elementary stream header to make it self-contained in
12、ISO/IEC 13818-1 Annex S. It further adds support for JPEG 2000 Ultra-Low Latency (ULL) encoding and transport of professional video, audio and data over Internet Protocol networks, by specifying the use of horizontal, independent JPEG 2000 stripes. Finally, it supports higher resolutions (4K or high
13、er) of JPEG 2000 video images by adding a new block mode. This new mode allows implementers to divide a given frame into blocks.

26、TU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and is
27、suing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these t
28、opics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expressi
29、on “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicabilit
30、y) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Reco
31、mmendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of
32、 claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recom
33、mendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

40、.4. NOTE Usage of J2K stripes requires J2K stripe mode (defined in 2.1.74) to be enabled in the J2K video descriptor. Such usage enables transport of a J2K video stream with a low end-to-end latency. 2.1.74 J2K stripe mode: Optional mode defined in S.4, dividing the (portion of) image transported in
