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.

HCOM is a Huffman-coded audio format from the early Macintosh era, designed to shrink digitized sound for distribution on floppy disks and bulletin board systems when storage was precious and modems were slow. The encoder takes 8-bit unsigned PCM input, computes a frequency table of sample-delta values, and builds an optimal Huffman tree that replaces common deltas with short bit sequences. Compression ratios of 2:1 or better were typical for speech recordings, a meaningful saving when a 3.5-inch floppy held only 800 KB. Files were distributed as Macintosh resource forks and played through utilities like SoundApp and the BinHex ecosystem that defined Mac software exchange in the late 1980s. The format supported sample rates up to 22.255 kHz, matching the output capabilities of original Macintosh sound hardware. Tools such as SoX retain HCOM decoding support, ensuring that archived recordings remain accessible decades later. HCOM holds three practical advantages for preservation work: lossless compression that recovers the original samples exactly, a self-contained Huffman table embedded in each file for dependency-free decoding, and historical prevalence across thousands of vintage Mac sound archives.
