Different Kinds Of A TV Tuner
Depending on television standards and the point from which broadcasts are to be watched, tuners can be separate or incorporated in television sets.
There are different kinds of television tuners depending on where it is applied. A television tuner card enables television signals to be viewed on a computer. Most cards are capable of recording broadcasted programs onto a hard disk to be viewed later.
The display from analogue TV cards is a raw video stream that can be normally viewed but requires to compression for it to be recorded. Cards that have tuners capable of acting as either analogue or hybrid tuners are referred to as hybrid. To switch between analogue and digital operation is easy but cannot be done instantly. This is because reconfiguration has to be done before switching from one system to another.
Combo tuners are similar to hybrid tuners in application aspects but have two separate tuners. Combo tuners act as analogue and digital tuners simultaneously without need of any reconfiguration. A viewer can watch digital transmissions while recording analogue transmissions or watch analogue while recording digital.
High quality tuners have hardware capable of encoding data. Most recent tuners have a large flash memory that stores firmware used for decoding a number of different video formats. This makes it possible to use such tuners in many regions nations without having to flash the firmware.
Cards can be flashed from one analogue format to another due to their similarity. Cards cannot be flashed from one digital format to another due to variation in necessary decoding logic. A mobile television tuner card is used in smart mobile phone handsets for watching television.
