Laptops are in some way ideal for use as a portable TV: they have large screens and a long-life battery, and are easy to connect with various external devices.
The most important extra device is a TV reception card which connects via USB. Recently released products offer high definition and better reception, thus making the most of your notebook, while a mobile digital multimedia broadcasting (DMB) service has just got underway.

The analog television cards of the past did not provide quality images, and consistency was also a problem. But digital broadcasts send a compressed signal that prevents disconnection.
HD TV cards are a new trend, too. For laptops, they usually connect via USB port. DViCO¡¯s Fusion HDTV 5 has a fifth-generation reception chip reducing interference, and USB power is all it needs to operate. The price is between W136,000 (US$136) and W163,000.
Terrestrial DMB technology was designed for portable devices, and this makes it fit for notebook PCs as well. However, DMB has a resolution of 320¡¿240, so the image quality may be low when viewed full-screen. The service is initially only available in the capital area, and there is no reception indoors or underground.
LG Electronics has a DMB reception card that can be linked with XNote LW20 and LW40. The price is around W100,000.
Receivers using USB are also available. Cobalt Technology will introduce a DMB receiver the size of a USB drive, and Ubibro has also developed a USB-type product. The internal antenna allows use even in cars. The Ubibro product costs around W100,000, and Cobalt Technology has not yet decided a price.
HDTV and DMB require standard receivers. The fact that there isn¡¯t any product that covers both is disappointing.
