WTV (Windows Recorded TV Show) is a digital video file format developed by Microsoft for use on Windows Media Center. It is a container format that stores video and audio data recorded by Windows Media Center from live television or other sources. WTV files are typically compressed using MPEG-2 video and Dolby Digital AC-3 or MPEG-1 Layer II audio codecs, providing high-quality video and audio. They also support additional metadata and information related to the recorded TV show, including episode and series information. WTV files can be played back on Windows Media Center or other compatible media players, and can be converted to other video file formats like MP4 or AVI using compatible media conversion software. They can also be edited using compatible video editing software. Overall, WTV is a useful video file format for recording and storing live television content on Windows Media Center. However, with the shift towards streaming services and on-demand content, it is not as widely used as other video file formats for digital video content distribution.
