What is a .NUV file?
The .nuv file format is associated with NuppelVideo, a video format used by MythTV, an open-source home entertainment application. It is designed to efficiently store TV recordings with minimal loss of quality.
Background
The NuppelVideo file format was developed to support MythTV, a popular open-source software that turns a computer into a digital video recorder. This format was chosen because it allows for efficient storage of video data, making it suitable for recording and replaying television broadcasts. Although not as widely used as other video formats like MP4 or AVI, .nuv files serve a niche purpose within the MythTV community. Users of MythTV can record, pause, and replay live TV, and the .nuv format is a key component of this functionality. The format is designed to be lightweight and efficient, which is crucial for managing large amounts of recorded TV content.
