Understanding TS files

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.
