9、tional Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fiel
10、ds of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and 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 j
11、oint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical commit
12、tee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

34、n a program map table or program stream map. 4) Clause 2.11.3.1 At the end of clause 2.11.3.1 add: Additionally, an ISO/IEC 14496 audiovisual scene may refer to non SL-Packetized streams carried in an Rec. ITU-T H.222.0 | ISO/IEC 13818-1 transport stream using a “pid:/PID_NUMBER“ URL scheme instead
35、of a “od:/OD_ID“ URL scheme. ISO/IEC 14496 streams may derive their time base from the PCR of the program through the OCR_ES_ID mechanism. 5) Clause 2.11.3.3 a) In clause 2.11.3.3, add the following new bullet point to the end of the first list of bullet points: The object time base of an SL-packeti
36、zed stream whose OCR_ES_ID identifies a non SL-packetized stream with a PID equal to the PCR PID is fstc(t) / 300 b) Replace the last paragraph of clause 2.11.3.3 with: For SL-packetized streams inheriting their object time base from the PCR PID, the following considerations apply: TimeStampResoluti
37、on = 90000 / 2k, with k a positive integer larger than or equal to zero. TimeStampLength = 33k. For SL-packetized streams carrying an OCR, the relationship between a value of the STC and the corresponding value of the object time base of a stream is established by associating PTS fields in PES packe
38、t headers with the OCR or FCR in SL packet headers and FlexMux Stream packets respectively, as specified in 2.11.3.6 and 2.11.3.7. For SL-packetized streams inheriting their time base from the PCR, the object time base of such a stream is fstc(t) / 300. 6) Clause 2.11.3.8 a) In clause 2.11.3.8, repl

42、SO/IEC 14496 table. The ISO/IEC 14496 table may be transmitted in multiple ISO_IEC_14496_sections. after: It is not required that a complete table be received in order to process its payload. However, the payload of sections shall be processed in the correct order, as indicated by the value of the s

A value of 0x04 indicates an ISO_IEC_14496_scene_description_section that carries an ISO/IEC 14496-1 scene description stre
44、am. A value of 0x05 indicates an ISO_IEC_14496_object_descriptor_section that carries an ISO/IEC 14496-1 object descriptor stream. with: This 8-bit field shall be set to 0x04, 0x05, or 0x08, in case of an ISO_IEC_14496_section. A value of 0x04 indicates an ISO_IEC_14496_section that carries an ISO/I
45、EC 14496-1 scene description stream. A value of 0x05 indicates an ISO_IEC_14496_section that carries an ISO/IEC 14496-1 object descriptor stream. A value of 0x08 indicates an ISO_IEC_14496_section that carries other ISO/IEC 14496 streams. 7) Annex Ra) In clause R.2, replace the following bullet: Loc
46、ate the additional streams using their ES_ID and the stream map table.with: Locate the additional streams using their ES_ID and the stream map table. If ODUpdate_descriptors are present in the first descriptor loop, process the ObjectDescriptor_Update asdefined in 2.6.92.b) At the end of Annex R add
47、:Figure R.3 gives an example of ISO/IEC 14496 program elements in a transport stream, consisting of a scene description stream (BIFS-Command), and audio and video streams natively carried over PES (no SL packetization or FlexMux). BIFS-Command stream are conveyed by means of ISO_IEC_14496_sections,
48、and the BIFS scene directly refers to the audio and video streams in the transport stream through “pid:/“ URLs in the BIFS media nodes.
