High-definition (HD) digital video recorders (DVRs) are revolutionizing the way people watch television. Satellite and cable TV companies often offer them as incentives for signing up for their services, though they can be purchased separately. They serve the same purpose as a VCR: to record and save shows for later viewing. However, the advanced technology of HD DVR recorders makes them infinitely superior to VCRs in a number of ways.
Digital Recording
DVR recorders save programs as data on their hard drives, rather than recording them onto tapes like VCRs. Because there are no moving parts, they last for much longer, and the recordings will never wear out in the way VHS tapes do.
More Storage Space
DVR hard drives are capable of storing much more information than an old VHS tape or even a DVD. They let the user preserve hundreds of hours of programming in some cases, compared to 6 or 8 hours on a VHS tape.
High Definition
Shows broadcast in high definition contain much more information in the signal than standard shows. The sounds and images are much sharper and clearer.
HDTVs
In order to properly view a show in HD, you need an HD television set, which has the screen capacity to broadcast the show as it was meant to be seen. Standard TVs will show an HD program, but it won't have the same clarity as it would with HD.
More Space
An HD DVR recorder allows HD shows to be stored and broadcast in original clarity on an HD television. The recording process is not different, although an HD program takes up more space on your HD DVR recorder (leaving less space free for other programs).
