'''MPEG transport stream''' ('''[[MPEG]]-TS''', '''MTS''') or simply '''transport stream''' ('''TS''') is a standard [[digital container format]] for transmission and storage of [[Digital audio|audio]], [[Digital video|video]], and [[Program and System Information Protocol]] (PSIP) data.<ref name="afterdawn-ts">{{cite web|url=http://www.afterdawn.com/glossary/term.cfm/mpeg2_transport_stream |title=MPEG-2 Transport Stream |website=AfterDawn.com |access-date=8 June 2010}}</ref> It is used in broadcast systems such as [[DVB]], [[ATSC]] and [[IPTV]].

Transport stream specifies a container format encapsulating [[packetized elementary stream]]s, with [[error correction]] and [[synchronization pattern]] features for maintaining transmission integrity when the [[communication channel]] carrying the stream is [[Degradation (telecommunications)|degraded]].

Transport streams differ from the similarly named [[MPEG program stream]] in several important ways: program streams are designed for reasonably reliable media, such as discs (like [[DVD]]s), while transport streams are designed for less [[Reliability (computer networking)|reliable]] transmission, namely [[Terrestrial television|terrestrial]] or [[Satellite television|satellite broadcast]]. Further, a transport stream may carry multiple programs.

Transport stream is specified in ''[[MPEG-2]] Part 1, Systems'', formally known as ''[[ISO/IEC]] standard 13818-1'' or ''[[ITU-T]] Rec. H.222.0''.<ref name="itu-spec" />
