Editing MPEG transport stream (section)

==Use in Blu-ray==
Blu-ray Disc video titles authored with menu support are in the [[Blu-ray Disc Movie]] (BDMV) format and contain audio, video, and other streams in a BDAV container, which is based on the MPEG-2 transport stream format.<ref name="bdvm">Afterdawn.com [http://www.afterdawn.com/glossary/terms/bd-mv.cfm Glossary – BD-MV (Blu-ray Movie) and BDAV container] {{webarchive|url=https://web.archive.org/web/20090218234755/http://www.afterdawn.com/glossary/terms/bd-mv.cfm |date=18 February 2009 }}, Retrieved on 26 July 2009</ref><ref name="bdav">Afterdawn.com [http://www.afterdawn.com/glossary/terms/bdav.cfm Glossary – BDAV container], Retrieved on 26 July 2009</ref> Blu-ray Disc video uses these modified MPEG-2 transport streams, compared to DVD's program streams that don't have the extra transport overhead.

There is also the BDAV (Blu-ray Disc Audio/Visual) format, the consumer-oriented alternative to the BDMV format used for movie releases. The BDAV format is used on [[Blu-ray Disc recordable]] for audio/video recording.<ref name="bdav" />{{efn|Filename extension [[.m2ts]] is used on Blu-ray Disc video files which contain an incompatible BDAV MPEG-2 transport stream due to the four additional octets added to every packet.<ref name="bda-av" /><ref name="bdav-videohelp">Videohelp.com [http://www.videohelp.com/hd What is Blu-ray Disc and HD DVD?] {{webarchive|url=https://web.archive.org/web/20091224035325/http://www.videohelp.com/hd |date=24 December 2009 }}, Retrieved on 26 July 2009</ref>}} Blu-ray Disc employs the MPEG-2 transport stream recording method. This enables transport streams of a BDAV converted digital broadcast to be recorded as they are with minimal alteration of the packets.<ref name="bda-bdre" /> It also enables simple stream cut style editing of a BDAV converted digital broadcast that is recorded as is and where the data can be edited just by discarding unwanted packets from the stream. Although it is quite natural, a function for high-speed and easy-to-use retrieval is built in.<ref name="bda-bdre" /><ref name="bda">Blu-ray Disc Association (August 2004) [http://www.blu-raydisc.com/Assets/Downloadablefile/general_bluraydiscformat-15263.pdf Blu-ray Disc Format, White paper] (PDF) Page 22, Retrieved on 28 July 2009</ref>
