TS (Transport Stream) is a digital video file format used for storing and transmitting digital video and audio data. It is commonly used for broadcasting digital TV signals and for storing video content on DVDs and Blu-ray discs. TS files are typically used for storing MPEG-2 or H.264 compressed video data and can contain multiple audio and video streams, making them well-suited for storing high-quality video content. The format is designed to be able to handle interruptions in the transmission of data, making it suitable for use in live broadcasting and other real-time applications. TS files can be played back on a variety of media players, including VLC and Windows Media Player, and can also be converted to other more widely supported video formats like MP4 or AVI using compatible media conversion software. Overall, TS is a useful video file format for storing and transmitting high-quality video content, particularly in the broadcasting and home entertainment industries. However, it is not as widely used as more modern video file formats like MP4 or MOV.
