What is it about sport that makes it so attractive to people? Is it the adrenaline rush of competitive and/or dangerous sport? Is it the ?feel good? factor of recreational sport; is it the opportunity of socialising with others, or perhaps all of the above? Whatever the reasons may be, sport is certainly getting more and more popular, especially in the developed world.
A major factor in the popularity of sport is the role of modern technology. Improvements in modern technology have resulted in better playing conditions and equipment for players as well as greater viewing pleasure for spectators.
Perhaps the greatest changes have taken place in the designing of sporting facilities - such as modern sports surfaces and improved artificial lighting that offer increased opportunity to play. Modern sports surfaces are low maintenance, therefore low cost, and allow year round use. Professional technical expertise is needed to design and install a modern sports surface. Properties such as its ?rebound resistance?, ?slip resistance?, and ?shock absorption? are measured to ensure that the surface is going to provide optimum playing conditions for that sport, whilst giving players ease of movement and adequate protection from injury. Regular maintenance of sports surfaces, both outdoor and indoor is recommended to ensure safety of players.
Along with an increased number of players there are also an increased number of viewers all over the globe. With the spread of satellite TV, events in one part of the world can be watched real time, in another. Modern flood lighting has not only allowed greater use of sports facilities at the recreational level, but also made possible higher-level competition fixtures such as day-night cricket matches, night-time football matches etc. Electronic score boards, photo-finish timing devices, slow motion replays and large viewing screens have also added to the viewing pleasure of spectators.
Modern materials are used in the manufacture of synthetic sports surfaces as well as sports equipment. Third generation synthetic grass is made from polymers and provides a maintenance free all-weather surface for sports. The use of composite materials makes sports equipment such as rackets and protective gear, lighter and more durable, enabling athletes to further improve their performance. Advances in modern technology have also led to improvements in the design of sports equipment such as trainers and sports shoes, starting blocks for use in athletics, pole vaults etc.
Whilst it is difficult for the average user of sporting equipment to keep up with the latest developments, as a guide in the UK sports equipment and sports facilities and surfaces should comply with British standards. Some governing bodies of individual sports also offer certification to demonstrate compliance with international standards.
Advances In Modern Technology
With the advancement of technologies, satellite television came in to existence. Satellite television is a revolution when compared to terrestrial and cable television, as it received signals from communication satellites in the space. In many places these satellite television supplement its conventional counterparts to get wide range of channels.
For years, satellite television is not an acceptable one as it had many disadvantages of fixing a very large satellite in a place and then lining it to the appropriate satellite. It even took months to set it by trail and error method. Bad weather is always a hindrance to this method of broad casting.
In the conventional method, the radio wave signals often disrupted and proper broadcasting was not possible as it was not inline with the antenna, which transmits these signals to the surrounding area. To get a perfect signal you should be very close to the broadcasting area.
Whereas satellite television, receives the signal from satellite dishes, which is in the geo-synchronous orbit of the space. It orbits in elliptical inclination or in geostationary orbit of 37,000 km above the earth.
Earlier in 1980's the Consumer satellite television reception was highly were expensive and the dishes used were as large as 12-foot height. It had a motorized, multiple satellites reception. In 1995, easily usable small dish network came in to existence. Now, direct broadcast satellite (DBS) is usage to enable the satellite provider to select programs and broadcasts them to subscribers as a set of packages. It is a digital broadcast, which means transmission happens in Ku frequency range (12 GHz to 14 GHz).
Like other Satellite relayed communication, Satellite television uses an antenna, which is mainly located in uplink direction. These are mainly nine to twelve meters in diameter. These large structures are required for accurate and increased signals from satellites. These uplinked dishes placed in such a way that they receive to a particular frequency range from the satellite, which is in the space. Then these satellites in space, retransmits, or resend the signals back to these uplinked dishes in earth in a highly different frequency from the previous one. These kind of receiving the signals are termed as downlink. C-band and Ku -band are used for uplink service. The signal, received from the space, becomes weak. Therefore, these uplink dishes do conversions of the signals to low- noise block down converter. Then these radio waves get converted in to electrical signals from C-band and Ku -band to L-band. The L-band receives the signal through coaxial cable and converts in to desired output.
However, the process may look very complicated. These are the units, which are the eye of the satellite television, which helps in uninterrupted service of information and makes a pathway for everybody to enjoy the new access to the information age.
