Reference software is normative in the sense that any conforming implementation of the software, taking the same<\/p>\n
conformant bitstreams, using the same output file format, will output the same file. Complying ISO\/IEC 14496<\/p>\n
implementations are not expected to follow the algorithms or the programming techniques used by the reference<\/p>\n
software. Although the decoding software is considered normative, it cannot add anything to the textual technical<\/p>\n
description included in parts 1, 2, 3 and 6 of ISO\/IEC 14496.<\/p>\n
The software contained in this part of ISO\/IEC 14496 is divided into three categories:<\/p>\n
a) Elementary stream decoding software <\/b>is catalogued in clauses 3, 4 and 5. This software accepts<\/p>\n
elementary streams encoded according to the normative specification in parts 1, 2, 3 and 6 of ISO\/IEC 14496<\/p>\n
and decodes the streams into the media types associated with each elementary stream. While this software<\/p>\n
appears in the normative part of this specification, attention is drawn to the fact that the implementation<\/p>\n
techniques used in this software are not considered normative ? several different implementations could<\/p>\n
produce the same result ? but the software is considered normative in that it correctly implements the decoding<\/p>\n
processes described in parts 1, 2, 3 and 6 of ISO\/IEC 14496.<\/p>\n
b) Elementary stream encoding software <\/b>is catalogued in Annex A (informative). This software creates<\/p>\n
elementary streams from associated media types. The encoders are provided as a means to obtain<\/p>\n
elementary streams with the normative syntax described in parts 1, 2 and 3 of ISO\/IEC 14496. The techniques<\/p>\n
used for encoding are not specified by this specification, and the quality and complexity of these encoders has<\/p>\n
not been optimized.<\/p>\n
c) Utility software <\/b>is catalogued in Annex B (informative). This software was found useful by the developers of<\/p>\n
the standard, but may not conform to the normative specifications given in parts 1, 2, 3 and 6 of<\/p>\n
ISO\/IEC 14496.<\/p>\n
File locations given in this part of ISO\/IEC 14496 are expressed relative to its location in the source tree.<\/p>\n","protected":false},"excerpt":{"rendered":"
