What is a TS file?

The TS (Transport Stream) format is a standard container specified in MPEG-2 Part 1 (ISO/IEC 13818-1) for the transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data. Designed for unreliable transmission environments like broadcast and streaming, TS encapsulates data in fixed-size 188-byte packets to facilitate error correction and stream synchronization. It is the standard format for digital broadcasting systems such as DVB, ATSC, and IPTV, and often contains MPEG-2 or H.264 (MPEG-4 AVC) video streams.

How to open a TS file

Many native video players have limited support for raw MPEG Transport Streams. VLC media player is the primary tool for opening TS files across Windows, macOS, and Linux, as it natively handles the demultiplexing of the packetized stream. For editing or converting, tools like FFmpeg or HDTV-to-MPEG2 are used to parse the transport packets and extract the elementary streams.

What is an AVI file?

Audio Video Interleave (AVI) is a multimedia container format introduced by Microsoft in 1992 as part of the Video for Windows technology. It adheres to the Resource Interchange File Format (RIFF) specification, storing audio and video data in tagged chunks (specifically 'movi' lists) to allow synchronous playback. While widely compatible, the legacy AVI architecture lacks native support for modern features found in MP4 or MKV, such as variable frame rates (VFR), B-frames, and sophisticated chapter markers. It typically utilizes codecs like DivX, Xvid, or MJPEG.

How to open an AVI file

AVI files enjoy broad compatibility on Windows via Windows Media Player. However, because AVI is a container that can hold various codecs (e.g., DivX, Xvid), playback may fail if the specific codec is missing. macOS users can view AVI files using QuickTime Player if the content is MJPEG, but third-party players are often required for other codecs. VLC media player and MPC-HC are standard recommendations for handling the vast array of codecs potentially encapsulated within an AVI file.
