Modern intakes of satellite television let out taking into account possibility of its expeditious reorganization on frequency. Also the receivers realizing the programmed reorganization not only on frequency but also on orientation to an artificial satellite are developed.
Dream of the person of opportunity on any distances to see reflected in legends and fairy tales of many on childbirth. It was succeeded to achieve this dream in our century when the general development of science and equipment prepared a basis for transfer of the image on any distance.
Reception stations "Orbita" were constructed practically in all large cities of the remote Areas of Siberia, Far North, the Far East. At the same time construction of such stations in small settlements with the population in some thousands of people is almost unprofitable. Therefore further development of Orbit system was stopped.
It is possible to calculate that in the satellite channel with a capacity. 25 Mbit/g can be transferred four-five programs of the high quality corresponding to the main channels of submission of programs, or 12 programs with the quality corresponding to the VHS standard videorecorder.
The reception antenna of terrestrial station has the small diameter of a mirror (2,5 m) and weight no more than 400 kg; directional pattern width ± 1 °. As the input device became possible to apply not cooled parametrical amplifier with a temperature of noise of 100 K. All other radio engineering equipment is placed in a small rack. Thus, the system with reception on rather simple stations in the range of 4 GHz which are not demanding continuous qualification service is created distributive by TV.
Japan rather far promoted in introduction of TVCh. The necessary studio equipment is developed, receivers went on sale of TV, regular transfers in the MUSE standard via the broadcasting BS-satellite are conducted
