9、 toCAN/CSA-ISO/IEC 13818-1:15ISO/IEC 13818-1:2013/Amd.2:2014(E) Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC particip
10、ate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental a
11、nd non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The
12、 main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies c
13、asting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Amendment 2 to ISO/IEC 13818-1:2013 was prepared by Joint Technical Committee

ITU-T H.264 | ISO/IEC 14496-10, the MVC extension descriptor provides
24、 information about the AVC video stream resulting from reassembling (up to) the associated MVC video sub-bitstream and provides information about the contained MVC video sub-bitstream and for the reassembly of the associated MVC video sub-bitstream. There may be one MVC extension descriptor associat
25、ed with any of the MVC video sub-bitstreams (with stream_type equal to 0x20) of an AVC video stream conforming to one or more profiles defined in Annex H of Rec. ITU-T H.264 | ISO/IEC 14496-10. When the MVC video sub-bitstream is an MVC base view sub-bitstream, the MVC extension descriptor shall be
26、present in the associated PMT or PSM for stream_type equal to 0x1B. This descriptor can also be used by applications that require association between stereoscopic MVC views and left or right eye using the syntax elements view_association_not_present and base_view_is_left_eyeview.

When this flag is set to 1 no such association is signalled. ba
30、se_view_is_left_eyeview This flag shall be set to 1 when the view_association_not_present_flag is set to 1 and no view association is conveyed in the descriptor. When the view_association_not_present_flag is set to 0 and this flag is set to 1, it indicates that the base view is associated with the l
31、eft eye view (or enhancement view is associated with the right eye view). When the view_association_not_present_flag is set to 0 and this flag is set to 0, it indicates that the base view is associated with the right eye view (or enhancement view is associated with the left eye view). 4) Clauses 2.6

When present, the descriptor shall only be located in the lo
33、op following the program_info_length field in the PMT. If the descriptor is not included in the PMT, then the associated transport stream conforms to the strict profile.

36、 0x03-0x0F reserved 0x0F-0xFF user_private (see Note 3) NOTE 1 Transport streams using this profile conform to all the normative definitions for transport streams. These include conformant discontinuities, PCR jitter/accuracy, strict T-STD management, PCR interval conformance (less than 100 ms), as
37、well as PTS/DTS interval (0.7 seconds) and compliance. NOTE 2 Transport streams using this profile conform to all the normative definitions for transport streams with the following exceptions: The PCR jitter may exceed the specified tolerance as applications that use this profile usually do not incl
38、ude null-PID packets. Clients that process these streams usually do not use the PCR to derive the decoder STC. However, the PCR value can be used in conjunction with the PTS and DTS for conformant STD management of all the media components in the associated program; the PCR interval occasionally exc
39、eeds 100 ms in applications that use this profile due to occasional bit rate variations in certain locations; conforming continuity counter errors and time base discontinuity may occur more frequently than in complete profile. NOTE 3 User private values of transport_profile that need unique identifi
40、cation can use the MPEG registration_descriptor with a unique format_identifier value that is obtained from the Registration Authority. 5) New Annex T Add the following after Annex S: Annex T MIME type for MPEG-2 transport streams (This annex does not form an integral part of this Recommendation | I

46、s. This might compromise the functionality of the receiver or even crash it. An MPEG-2 transport stream is an extensible container format, and hence might carry streams that have active aspects (e.g., contain script snippets). If those subsystems are not properly defined or implemented, it may be po
47、ssible to crash the receiver or temporarily make it unavailable.
