Many streams are often mixed together, such as several different television channels, or multiple angles of a movie.Įach stream is chopped into (at most) 188-byte sections and interleaved together. The receiver parses and decodes one of the streams.Ī transport stream encapsulates a number of other substreams, often packetized elementary streams (PESs) which in turn wrap the main data stream using the MPEG codec or any number of non-MPEG codecs (such as AC3 or DTS audio, and MJPEG or JPEG 2000 video), text and pictures for subtitles, tables identifying the streams, and even broadcaster-specific information such as an electronic program guide. Multiple MPEG programs are combined then sent to a transmitting antenna. Transport stream is specified in MPEG-2 Part 1, Systems, formally known as ISO/IEC standard 13818-1 or ITU-T Rec. Further, a transport stream may carry multiple programs. 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 DVDs), while transport streams are designed for less reliable transmission, namely terrestrial or satellite broadcast. Transport stream specifies a container format encapsulating packetized elementary streams, with error correction and synchronization pattern features for maintaining transmission integrity when the communication channel carrying the stream is degraded. It is used in broadcast systems such as DVB, ATSC and IPTV. MPEG transport stream ( MPEG-TS, MTS) or simply transport stream ( TS) is a standard digital container format for transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data.

It should also be possible to insert the TS Analyser/TS Monitor in between the client and the server and monitor the stream for the boundaries configured. The goal of TS Info is to be an easy to use MPEG-TS (MPTS/SPTS) analyser with all the information, analysis and validation right under you finger tips. DVBsnoop ( ) is the only application that is only one that comes near this goal, but it is a commandline utility. However analysing and checking validity of MPEG-TS streams is not really possible. In the Open Source multimedia field there are various choices for multimedia streaming and playback.
