MPEG Transport Stream - Use in Blu-ray

Use in Blu-ray

Filename extension.m2ts is used on Blu-ray Disc Video for files which contain BDAV MPEG-2 transport stream. Blu-ray Disc Video titles authored with menu support are in the BDMV (Blu-ray Disc Movie) format and contain audio, video, and other streams in a BDAV container, which is based on the MPEG-2 transport stream format. 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 BD-REs and BD-Rs for audio/video recording. Blu-ray Disc employs the MPEG-2 transport stream recording method. That enables transport streams of digital broadcasts to be recorded as they are without altering the format. It also enables flexible editing of a digital broadcast that is recorded as is and where the data can be edited just by rewriting the playback stream. Although it is quite natural, a function for high-speed and easy-to use retrieval is built in. Blu-ray Disc Video use MPEG-2 transport streams, compared to DVD's program streams. This allows multiple video programs to be stored in the same file so they can be played back simultaneously (e.g. with "picture in picture" effect).
