About formats

WTV (Windows Recorded TV Show) is a digital video recording format developed by Microsoft and introduced in July 2008 with the Windows Media Center TV Pack for Windows Vista. The format was designed to replace the earlier DVR-MS recording format used by Windows Media Center, offering a more capable container for recording live television broadcasts. WTV files store video in MPEG-2 or H.264 encoding alongside multiple audio tracks in AC-3 or MPEG audio format, along with closed caption data, electronic program guide metadata, and copy protection flags. The container uses an internal directory structure that supports time-shifting features, allowing Windows Media Center to record content while simultaneously enabling playback from the beginning of the recording. A rich metadata framework preserves detailed program information from the electronic program guide (EPG), including show title, episode description, genre, ratings, and original air date, making it easy to organize and browse recorded content. The format supports both standard definition and high definition recordings from digital cable, over-the-air ATSC, and ClearQAM tuner sources. WTV files are natively accessible through Windows Media Center and can be converted to the simpler DVR-MS format using built-in Windows tools. While Windows Media Center was discontinued after Windows 7 (with limited support in Windows 8), WTV files remain in personal media archives and can be processed by third-party video tools.

AMB files contain audio encoded in Ambisonic B-format, a full-sphere surround sound technique conceived by Michael Gerzon during the 1970s. Unlike channel-based systems such as 5.1 or 7.1, Ambisonics captures a complete three-dimensional sound field using spherical harmonics — first-order B-format consists of four channels: W (omnidirectional), X (front-back), Y (left-right), and Z (up-down). This representation is speaker-independent, meaning one recording can be decoded to any loudspeaker arrangement or binaural headphones without remixing. AMB files typically store uncompressed PCM data and are processed by tools like SoX or specialized plugins. A core advantage is spatial flexibility — creators produce one master file that adapts to stereo, surround, or immersive playback. The format also scales elegantly: higher-order Ambisonics adds channels for increased spatial precision upon the same mathematical framework. With the growth of virtual reality, 360-degree video, and spatial audio for gaming, Ambisonics has experienced a resurgence, adopted by platforms like YouTube for immersive media delivery.
