BDs use the MPEG-2 Transport Stream (M2TS) container file format under the .m2ts filename extension. Video, audio, graphics, and other streams are stored and multiplexed (muxed) into this container.
It is a variant of MPEG Transport Stream format (ITU-T H.222.0 | ISO/IEC 13818-1).Muxing is a method of combining multiple analog or digital signals into one signal over a shared medium. When a BD is inserted into a player, it reads and pre-loads the muxed data (Graphics/SFX/Text) into the preloading memory buffer before the Primary Video stream. The decoding and demuxing process operates on a clock of 27 Mhz.
