Digital video recorder
A digital video recorder ( DVR , English for digital video recorder ) is a device that can digitally record television signals and usually also play them back. Devices of this type came onto the market in the late 1990s .
The devices can be roughly divided into two criteria:
- Digital data are received and stored unchanged or
- Analog signals are first digitized ; they are saved on an internal, permanently installed data carrier ( hard disk recorder ) or on a changeable one ( DVD recorder ).
In addition to the DVD player , the digital video recorder is one of those devices that pushed the analog video recorder out of the market. Today's devices also allow the function of time-shifted television (time shift) . Cable network operators also offer HD DVR devices that combine the functions of a digital video recorder and digital receiver with a set-top box and also enable HD recordings .
