Transport stream(TS, TP, MPEG-TS, or M2T) is a communications protocol for audio, video, and data which is specified in MPEG-2 Part 1, Systems (ISO/IEC standard 13818-1). Its design goal is to allow multiplexing of digital video and audio and to synchronize the output. Transport stream offers features for error correction for transportation over unreliable media, and is used in broadcast applications such as DVB and ATSC. It is contrasted with program stream, designed for more reliable media such as DVDs.
TS format is a container format that encapsulates pocketsize elementary streams and other data.
Important elements of a transport stream: Packet, PID, Programs, Program Specific Information (PSI) , 1 PAT , PMT , PCR , Null packets

Modifications of transport stream specification for random-access media (M2TS)
Transport Stream was designed for tape and broadcast, but it required modifications for usage with random-access media devices like new generation of digital camcorders that record onto DVD disks, hard drives or solid-state memory cards.
Random-access based systems may save data packets into a temporary buffer if a storage device is not ready, for example on device startup. Packets are written out of order, and to keep track of them, a 4-byte timecode (TC) is added to standard 188-byte packets. The result is a 192-byte packet. This is what is informally called M2TS stream. Sony calls it "BDAV MPEG-2 transport stream". JVC calls it TOD (possibly an abbreviation for "Transport stream on media") when used in HDD-based camcorders like GZ-HD7.[9] M2TS transport stream is also used for AVCHD video files, which often have MTS extension.
