DVR Recorder, PVR Recorder: A digital video recorder (DVR) or personal video recorder (PVR) is a device that records video in a digital format to a disk drive, USB flash drive, SD memory card or other memory medium within a device. The term includes stand-alone set-top boxes, portable media players (PMP) and recorders (PMR as camcorders that record in memory cards) and software for personal computers which enables video capture and playback to and from disk. More and more manufacturers have started to offer television sets with digital video-recording hardware and software built into the television itself.
