What is the digital TV

For televiewers:

Possibility to be connected for one day to a high-quality signal without wires, without a plate and without the permission of a house manager;
The digital TV moves together with you to new apartment and on a summer residence;
Television programs in a format of announcement HD (TV high difinition), thus possibilities of new plasma TVs will be used to the full ;
Viewing of teleprograms in mobile transport: a tram, the bus, the personal car (Mobile TV);
Possibility to take part in the program it is direct during translation. The way to order the goods, services or to be trained from it is far, not leaving from the house (Interactive TV).

For teleradio of the speaker:

Placing of new television channels at the expense of tenfold increase in possibility of a frequency resource;
The increase in time of vision of the TV - to a traditional prime-time will be added morning/evening by the day prime time at the expense of reception of a television signal in private and public transport and on mobile phones, computers, PDA;
Reduction of expenses for an announcement because expenses for operation of one television transmitter will be divided into some speakers;
High quality of the image at the expense of TVCH-TECHNOLOGY application (TV high difinition);
Possibility of realisation of essentially new projects of interactive programs.

Digital TV (Digital Television) - The way of transfer and reception of the compressed digital video signal, is modern alternative to traditional analogue TV and provides essentially higher quality of the image at equal expenses of means. The transferred television signal represents sequence of code (digital) combinations of electric impulses.

Advantages of digital radio TV:

Mobility. The radio digital TV, unlike other kinds of digital TV, carries out signal delivery to the consumer without superfluous wires. There is no necessity to get expensive equipment, to stretch cables, to cause masters. Everything, that is necessary for you – it is the TV, practically any UHF the aerial, the digital user's receiver and electric system presence! It is independent system, you can take it with yourselves in automobile travel, in the summer on a summer residence and to watch TV with the same quality, as in a city. In the long term programs of a digital aether "will move" and in a mobile phone.

High quality of a picture and soundtrack, high quality of broadcast channels. At a signal transmission the basic problem " Analogue" influence of various hindrances on a signal is, and digital TV practically is not subject to hindrances. Necessary level of a signal for qualitative viewing of television channels in a digital format much more low, than in the analogue. In other words, there, where analogue TV will go very poorly with noise and hindrances, the digital signal will pass in that quality in which it is formed in television studios.

Increase in number of transferred channels at the expense of use of advanced format MPEG-4. In this standard the algorithm of compression of the image is improved. Therefore in due course the quantity of transferred channels will not concede to cable TV.

Confident reception of a signal is possible even on the building ground floors where the aerial can catch only the reflected signal, without direct visibility of a transferring tower.

Simple and fast connection. Be connected to digital TV everyone can for one day without attraction of experts, without wires, without a plate and without the permission of a house manager.

The digital user's receiver – this not only qualitative TV, but also weight of pleasant additions: to subscribers of radio digital TV will be shortly accessible the Internet, the Teleguide and many other things.

Standards of a digital announcement

There are some families of standards of a digital. В первую очередь – This family DVB (Digital Video Broadcasting), the general open European standard of digital transmission of the multimedia, accepted by the European union of telecasting ETSI (European Transmission Standards Institute) and providing high quality of translation.
DVB has four main updatings:
DVB-T (For a radio land announcement);
DVB-C (For cable networks);
DVB-H (For a mobile announcement);
DVB-S (For satellite TV).

Other families of digital TV are realised in Japan (ISDB - Integrated Services Digital Broadcasting), in the North America and South Korea (ATSC - Advanced Тelevision Systems Committee).

Format of compression MPEG-4

In this standard the algorithm of compression of the image is improved, demanded speed of data transmission for an announcement of TV or radio programs that allows to increase number of programs in a strip of the channel of an on-air broadcasting is reduced.

The format of compression MPEG-4 is chosen with a view of economic feasibility of use of a frequency resource. The user's receivers offered by State Unitary Enterprise TSRRT, have possibility of reception of signals of digital TV in format MPEG-4.
