Television by ADSL

The television by ADSL , called sometimes TVoDSL , not to confuse with the Web TV, is the diffusion of chains televised by the signal ADSL. It is often about an offer grouped with a connection Internet, proposed by suppliers of access to Internet, often within the framework of an offer known as " triple play " combining Internet high banc, telephony on IP and TV.

The constraints come from the strong difference in flow between a flow of image animated (4 Mbit/s permanently) and that of a flow resulting from a navigation on the Web (some pages per minutes). Television requires a strong capacity and a management of the priorities between various flows. However the rise to power of the ADSL2+ makes it possible to consider a reception of quality in HD TV, with an theoretical output in reception of more than 20 Mbits/s (theoretical output).

Among the operators proposing this offer in France, one can quote:

However the advertisement of Free via its head office Iliad at the beginning of September 2006, taken again by France telecom, to develop a range Triple play on support Fiber optic from here 2012 opens a new voice of evolution to the diffusion of flow TV, within the framework of offer very high banc (with more than 50 Mbits/s theoretical).

With the Canada, déploiment of technologies VDSL is carried out slowly in the big cities, allowing the operator Bell ExpressVu to only offer this service to some particular customers.

In Belgium, Belgacom TV.

In practice for the user, the reception is carried out is on television via a case allowing the reference of the signal (such as a Freebox, a Neufbox, a Livebox…), that is to say on a computer connected to Internet via one of offers ADSL triple play, via the use of a software solution allowing to diffuse in streaming the video stream (for example, VideoLAN).

It should be noted that, as technology only makes it possible to send one program at the same time, the operator “knows” what you look at, when you look at it. What can pose a problem on the level of the Private life…

A new technology is about to be born, in the form of the The Venice Project, new software of the creators of Kazaa and Skype, which allows the diffusion of television by technology Peer to peer.
