What is a TS file?
Transport stream for broadcast and DVD video
TS files are container files for ‘packetized’ audio and video streams. The TS media container is commonly used in broadcast applications to broadcast media files over the internet. TS files are also used when authoring DVDs. The TS file format is also used by QT software in the development of GUI applications, but they are mainly used for DVDs and are compatible with various DVD players and video editing tools. The TS video stream compresses video data using the standard MEPG-1 (MPEG) video compression algorithm.
Common uses for TS files

- DVD authoring

Who works with TS files?
Broadcast engineers, satellite and cable operators, and television archivists handle TS files daily because the transport stream is the standard payload for over-the-air and IP-delivered TV. Media-monitoring teams and journalists also encounter .ts files when saving HLS streaming segments or capturing live news feeds.
TS vs MPG: which should you use?
Both TS and MPG carry MPEG-compressed audio and video, but they package it differently. TS splits the data into small fixed-size packets with error-resilience features built for live transmission over unreliable links, while MPG (an MPEG program stream) is optimized for storage and playback from reliable media such as discs and hard drives. TS suits capturing or relaying live broadcast and IPTV feeds; MPG suits locally stored video that desktop players need to open and seek through easily.
