Digital TV, the replacement of analog TV, is slowly gaining popularity in Europe. It's known as DVB-T, Freeview or TNT. For those who travel, it's easy to pick up the signal and watch local television on a laptop. The ingredients for DVB-T television are simple, however there are a few things worth mentioning.
 

Digital Television standards

As usual with new technology, there is more than 1 standard. In Europe and Australia it's DVB-T, in the US it's called ATSC. There are more standards, such as for china and south America but that's about it. Dominant are DVB-T and ATSC. In France DVB-T is called TNT. Read about free local TV in Spain called TDT or Free Digital TV in Portugal called TDT.

Digital TV transmitters

DVB-T is equivalent to high quality TV - however one should be well in reach of the transmitter. A big difference with analogue TV is poor DVB-T performance when signal reception is average or less. Image and sound get distorted easily, specially when using the HD (High Definition) variant. Analogue TV has better performance under difficult conditions, it's image fades with white noise and sound stays longer.
It also takes more power to transmit a DVB-T signal. Nonetheless the equipment needed to receive a DVB-T signal is simple, cheap and small - it fits a USB stick / adapter.

The TVCenter Pro software is moderately CPU intensive, however the PCTV stick heats up quite a bit. Power consumption is above average - so that's something to be aware of when using DVB-T.

DVB-T in France - called TNT.

DVB-T in France is called TNT (Télévision Numérique Terrestre) and is operational since 2007. The analogue variant is planned to be switched of in 2011. So let's have a look how it performs. A few tests in the north-east quickly made one thing clear - TNT has poor coverage in the country side. One needs to be in or near a city to receive the DVB-T signal. A high quality signal was first received in Le Puy en Velay - at a distance of about 1,5 Km from the transmitter on Mont Denise. The HD signal of Arte was poor at this close distance - however work was in progress at the antenna at the time of testing.

All information about DVB-T TNT in France is available through the TNT website.
