10、eneric coding of moving pictures and associated audio information: Systems Amendment 3 Carriage of green metadata in MPEG-2 systems Summary This amendment to ITU-T H.222.0 (2014) | ISO/IEC 13818-1:2015 specifies the carriage of “Green metadata“ in MPEG-2 transport streams. The amendment does not spe
11、cify carriage in program streams. Green metadata component is specified using a new stream_type and is associated with media component to optimize display power consumption. Carriage of this metadata consists of a “static“ part, which applies to an entire program, as well as a “dynamic“ part, which
12、can change for each media access unit. “Static metadata“ is specified using a descriptor in the program map table while “dynamic metadata“ is specified using the private table syntax.

ITU-T H.222.0 (2014)/Amd.3 (12/2015) iii FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of t
23、elecommunications, 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 issuing Recommendations on them with a view to standardizing tel
24、ecommunications 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 topics. The approval of ITU-T Recommendations is covered by the
25、 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 expression “Administration“ is used for conciseness to indicate both a
26、 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 applicability) and compliance with the Recommendation is achieved when all
27、 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 Recommendation is required of any party. INTELLECTUAL PROPERTY RIG
28、HTSITU 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 claimed Intellectual Property Rights, whether asserted by ITU
29、 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 Recommendation. However, implementers are cautioned that this may n
30、ot represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2016 All rights reserved.

41、of dynamic green metadata prepared in accordance with this standard. Figure 2-21 illustrates the buffer model for processing green access units. Rx Figure 2-21 Green access unit decoder processing model MPEG-2 transport stream packets come into the model at the left, and are filtered by PID. Packets
42、 whose PID matches the green access unit PID flow into the 512 byte transport buffer. These buffered packets are removed at a rate of Rx = 300 kbps (kilobits/second) and stored in the green access unit Eb buffer (2048 Bytes). Green access unit table sections are removed from the Eb buffer immediatel

The Eb buffer shall not overflow and the green access
44、unit section shall be available in the Eb buffer at least 100 ms before display_in_PTS. NOTE In the worst-case, a green AU would contain 4488 bits. Under such conditions, the Eb buffer is large enough to hold up to three green AUs and the rate Rx is high enough to allow the removal of green AUs that
