Encoder: codify video files in H.264 format and audio in AAC, MP3, AC-3 or EC-3. [10] This is encapsulated by MPEG-2 Transport Stream or MPEG-4_Part_14 to carry it. Segmenter: divides the stream into fragments of equal length. It also creates an index file that contains references of the fragmented files, saved as .m3u8. Distributor

M2TS supports Digital 3D as multiple files in a specific file structure for encoding stereoscopic video: MVC stereoscopic data is in .ssif files in the /BDMV/STREAM/SSIF/ directory and require a respective base .m2ts file. Digital 3D in QTFF and ASF is possible, but not standard. MP4 only supports Digital 3D at the video format level. [44]
