When digital video recorders hit the home entertainment market, they were deemed high end, highly technical products. However, major manufacturers such as TiVo and Sony have made digital video recorders more available to consumers, and most importantly, affordable. This recording device offers the same abilities the VCR, with a few more bells and whistles.
The concept of digital video recorders is familiar to the security industry. Digital video recording is the process of recording television and video digitally, which is technology first used in CCTV, closed circuit TV.
Digital video recorders are essentially entertainment devices with a hard drive. Much like VCRs and CCTV, DVRs allow consumers to record television programs for playback and viewing. However, DVRs are tapeless devices that save recorded data on the hard drive in a digital format, a function both CCTV and VCRs lacked. A television signal is fed into the digital video recording's built-in tuner through antenna, cable or satellite. It is then converted from analog data to a digital format, then sent to the hard drive for storage. Another component of DVR is the MPEG-2 encoder that receives the television signal, and then converts that signal back to analog so that it is television viewable. Digital video recorders run on an operating system, similar a computer's operating system. The hard drive houses the operating system, space for digital recording, and a television buffer that holds a live feed.
There are two methods of recording on digital video recorders. The first method is using a stand alone digital video recorder that records to hard drives, and the second option is a recorder that stores data in a DVD drive and hard drive. With the latter recorder, stored data can be burned on a DVD instead of using the digital video recorders' storage space.
Before purchasing a digital video recorder, consumers should be aware of the many options available. A cost effective method of having DVR capabilities would be utilizing the services offered by cable and satellite providers. The digital video recorders are essentially rented by the customer for a cheap monthly charge attached to a cable or satellite bill. Satellite companies such as Dish Network and DirecTV offer DVRs as a part of their monthly service; Comcast and Armstrong cable companies also have DVR services. Renting from cable and satellite companies is a cheap way to enjoy Digital video recorders.
Another option for consumers is purchasing digital video recorders from quality brand names such as Sony. Sony features two high definition DVRs with free electronic programming guide, and up to 200 hours of video recording. Another personal digital video recorder is TiVo; it is the cheap, popular option when purchasing digital video recorders. It costs less than $100 for the system, and a monthly fee is charged for the use of the TiVo Season Pass and Wish Lists. These tools are major functions that distinguish certain programs out of thousands to be recorded. More information is available at their respective websites, tivo.com and sony.com.
Digital video recorders replaced VCRs as consumers' choice for recording because of the highly technical advantages of the systems. The ability to pause and rewind live television still fascinates consumers enough to encourage their purchase of DVRs. The storage capabilities of digital video recorders is another advantage they hold over its predecessor, VCRs. It is clear VCRs are a remnant of stone age technology, while digital video recorders have ushered in the new wave of video recording.
