An M2TS file contain the high definition video on Blu-ray Disc and AVCHD. This file format is based on the MPEG-2 transport stream container and used for multiplexing audio, video and other streams.

A T-STD compliant constant rate Transport Stream for playback the arrival timestamp (ATS) of each packet needs to be recorded to be able to reconstruct.
