AVCHD to TS Converter

AVCHD (Advanced Video Coding High Definition) is a high-definition recording format jointly developed by Sony and Panasonic for use in consumer and semi-professional camcorders. Announced in 2006, the format records H.264/MPEG-4 AVC video at resolutions up to 1920x1080 with Dolby Digital or uncompressed LPCM audio, stored within an MPEG-2 transport stream container. AVCHD was designed to work with a variety of recording media, including optical discs, hard disk drives, and solid-state memory cards, giving camera manufacturers flexibility in hardware design. The use of H.264 compression delivers superior image quality at lower bit rates compared to earlier recording standards like DV and MPEG-2, enabling longer recording times on the same storage capacity. AVCHD supports progressive and interlaced scanning modes, accommodating both cinematic and broadcast-style shooting. The directory structure follows a strict specification that includes playlist files for navigating recorded clips, making it compatible with Blu-ray players when recorded to compatible disc media. An enhanced version, AVCHD 2.0, added support for 1080/60p progressive recording and 3D stereoscopic video. The format remains widely used in the camcorder market and continues to be supported by major video editing applications.

TS (MPEG Transport Stream) is a standard container format specified as part of the MPEG-2 systems layer (ISO/IEC 13818-1), standardized by the Moving Picture Experts Group in 1995. Transport streams are designed for communication and storage environments where data loss or corruption is possible, such as broadcast television, satellite transmission, and network streaming. The format divides content into fixed-size 188-byte packets, each carrying a 4-byte header with synchronization, error indication, and stream identification information. This packet structure enables receivers to rapidly resynchronize after signal interruptions, a critical capability for real-time broadcast delivery that distinguishes transport streams from program streams designed for reliable storage media. TS can multiplex multiple programs into a single stream, with Program Specific Information (PSI) tables describing the structure and content of each program. The format supports virtually any audio and video codec, though it most commonly carries MPEG-2 video, H.264, or HEVC alongside AAC, AC-3, or MPEG audio. TS is the backbone of digital television delivery worldwide, used by DVB, ATSC, and ISDB broadcasting standards as well as IPTV and OTT streaming services utilizing HTTP Live Streaming (HLS). Resilience, standardized structure, and broad codec support make TS equally at home in live broadcast chains and file-based recording workflows.
