Introduction of dual tuners

In 2003 many Satellite and Cable providers introduced dual-tuner DVRs. In the UK, BSkyB introduced their first PVR Sky+ with dual tuner support in 2001. These machines have two tuners within the same receiver to operate independently of one another. The main use for this feature is the capability to record a live program while watching another live program simultaneously or to record two programs at the same time while watching a previously recorded one. Some dual-tuner DVRs also have the ability to operate two separate television sets at the same time. The PVR manufactured by UEC (Durban, South Africa) and used by Multichoice has the ability to view two programs while recording a third using a triple tuner. With some machines, such as the Scientific Atlanta 8300DVB PVR, it is possible to view one program whilst recording two other programs according to the users preference.
