ITU-T H.262 (2000)/Amd.3 (03/2009) i INTERNATIONAL STANDARD ISO/IEC 13818-2 RECOMMENDATION ITU-T H.262 Information technology Generic coding of moving pictures and associated audio information: Video Amendment 3 New level for 108050p/60p Summary Amendment 3 to Recommendation I

9、TU-T H.262 | ISO/IEC 13818-2 specifies the new level to support 108050p/60p video format. Video applications to support 108050p/60p are emerging in the market and the extension of the ITU-T H.262 codec to support such a video format was desired by the industry. In the new level, only progressive vid

10、eo coding tools (frame discrete cosine transform and frame motion compensation) are allowed. Source Amendment 3 to Recommendation ITU-T H.262 (2000) was approved on 16 March 2009 by ITU-T Study Group 16 (2009-2012) under Recommendation ITU-T A.8 procedure. An identical text is also published as ISO/

11、IEC 13818-2, Amendment 3. ii Rec. ITU-T H.262 (2000)/Amd.3 (03/2009) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sect

12、or (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every

13、 four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. 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,

14、 the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntar

15、y. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) 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 neg

16、ative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the

17、use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of 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 Recommendati

18、on, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. 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.
