digital video recorder

Definition:

A device used to digitally record television programs so they can be watched at a later time. Unlike a VCR, a DVR stores its programming on a hard drive, much like a file is stored on your computer. DVRs typically allow you to record 100 or more hours of standard television programming (much less than that for high definition programming) and allow you to perform actions not possible with a VCR such as pausing live television or setting up a scheduled recording to record your favorite shows based on title, actor, director or key word.
