The Spanish law of Digital TV locates the analogical blackout in 2010
The project of law of the Terrestrial Digital Television (TDT), that has approved the Plenary Session of the Congress and enters the Senate now, tries to drive this technology, to liberalize the TV by cable and to foment pluralism

The transit of the analogical televisions to the system of digital diffusion will suppose a greater quality of image and sound, the increase of the number of channels and the access to numerous interactive services like the connection to Internet.

The future norm establishes that all the televisions leave the analogical system of transmission and emit all digitalis programs at the beginning of 2010 and suppresses the limit of three concessions of deprived television of state scope to extend the supply up to 22 channels in open and gratuitous.

The measures approved by the socialist Government to drive the terrestrial digital television were received from way different by the political parties and mass media.

Whereas the PSOE defends that a greater supply of television operators will favor informative pluralism and the enterprise competition, the PP demands the Government who has a discussion before with all the political forces, the Independent Communities and the sector.

In the scope of the communication, Antenna 3, Telecinco and other mass media rejected the audio-visual legislative modifications of the Government by imprecision and favoritism, whereas the Godó Group and the Group HASTE showed their surprise by the informative manipulations realized by these means.

The irruption in Europe of the terrestrial digital technology in the television in the middle of the Nineties was perceived like an alternative that offered infinite possibilities of application.

In the absence of a law that defined the frame of the new audio-visual technology, the model of terrestrial digital television (TDT) was designed in 1998 by the Ministry of Public Works and the Economy through a real decree and a ministerial order.

The Government adjudged in 1999 the first concession of terrestrial digital television of payment to I want TV, that he failed in 2002 due to financial and operative difficulties.

In 2000 he granted to the two licenses of state scope to Net TV, partnership led by Vocento, ABC publisher and Veo TV, managed by Calm, publishing of Expansion and Mark, and Unedisa, publisher of the World, that began their emissions in June of 2002.

Nevertheless the development of the TDT stopped by the price of the decoders, a supply of programming of low cost and the absence of hearings.

That it is the TDT?

The TDT is a system of diffusion of audio-visual signals that it transmits codified information digitally. With the terrestrial system, the transmission of the emissions is not carried out through satellites but of very powerful repeaters that emit the signals.

The Terrestrial Digital Television supposes a jump of quality with respect to the analogical television because it allows one better tuning of channels and one quality of clearer image.

One of the applications of the digital emission is the absence of interferences, the signal arrives always clear and without fog. With the digital receiver, the channels are tuned of automatic way and they do not need adjustments. In addition the images to digital television are transmitted in a format of 16:9.

Thanks to technology MHP (platform multimedia of the home) the users of digital television can accede to numerous interactive services like the connection to Internet, the access to the banking services and the electronic commerce. Nevertheless, the arrival of the new system has the cost to renew the 26 million televisions.

The conventional apparatuses of the users do not interpret the digital emissions and to be able to tune them the users they will need to acquire a new digital television or to incorporate a decoder to the present receivers. The collective antennas also will have to adapt. The unique requirement to be able to install the digital receiver is that the television has a euroconector entrance.
