A DVR, or Digital Video Recorder, is a device that allows users to record television programs for later viewing. It captures video content from cable or satellite sources and stores it on a hard drive. This technology enables viewers to pause, rewind, or fast-forward through recorded shows, providing greater flexibility in how and when they watch. DVRs often come with features like scheduling recordings, which lets users set specific times for their favorite programs. Many modern DVRs also offer streaming capabilities, allowing access to online content and additional features like video on demand.
