Many cable TV providers offer integrated units that combine PVR
functionality with a cable tuner (CCTV DVR). Cable tuners are needed to watch
digital broadcasts such as HDTV broadcasts, pay-per-view broadcasts and
video-on-demand broadcasts. A cable tuner is not needed for standard
analog broadcasts.
One key advantage of using an integrated cable TV / DVR unit is that only
one set-top box and remote control is needed. This saves space and
keeps life simple.
Some cable TV PVRs include two tuners which permit two programs to be
simultaneously recorded. Alternatively, a viewer can watch one digital
station live while recording another show on a different station.
The disadvantage of purchasing an integrate cable TV tuner/PVR is that
the PVR functionality will likely not work should should you
decide to change from a cable TV service to a satellite TV service.
Integrated units might also not have all the features that you would like.
