Scientific Atlanta 4642 DVR User Manual


 
Digital TV channels broadcast variable amounts of data, depending on the type of program being aired. For
instance, there may be times when a sports specialty channel broadcasts a larger quantity of data than channels
whose lineups are primarily made
up of talk shows or soap operas. Sports programs generally involve much
more movement, and more data are therefore required
to reproduce the images on your screen. The number
of recording hours available to you therefore varies according to the types
of programs you record.
HDTV (high-definition television) channels need to transmit 2 to 2.5 times more data than standard channels
to reproduce a higher
quality image on your screen. Your PVR HD is equipped with a high-capacity hard drive
(500 gigabytes) that lets you record up to
55 hours of high-definition content, or up to 280 hours of
standard-definition content.
