Plant ware broadcasting equipment

Without any doubt, the future of the broadcast industry will be increasingly influenced by the Cloud-based technologies, but today is there still a place for on-premise video servers? And if so, what will these servers look like and how will they operate? Will everything be remote production over IP networks? If you believe the hype, traditional broadcast operations such as channel playout and other applications are increasingly being replaced by Cloud-ware to provide instant television services at a fraction of the cost of the old hardware-based solution. For now, for many, this is just a pipe dream, especially in developing regions of the world where IT infrastructure is not sufficiently developed to support these facilities. For at least the next five years there will be a need for conventional server solutions, used in association with other components such as workflow automation and media asset management systems.

Dear readers! Our articles talk about typical ways to solve the issue of renting industrial premises, but each case is unique.

For Europe the MW band ranges from The term is a historic one, dating from the early 20th century, when the radio spectrum was divided on the basis of the wavelength of the waves into long wave LW , medium wave, and short wave SW radio bands.

Wavelengths in this band are long enough that radio waves are not blocked by buildings and hills and can propagate beyond the horizon following the curvature of the Earth; this is called the groundwave. Practical groundwave reception typically extends to — miles, with greater distances over terrain with higher ground conductivity , and greatest distances over salt water.

Most broadcast stations use groundwave to cover their listening area. Medium waves can also reflect off charged particle layers in the ionosphere and return to Earth at much greater distances; this is called the skywave.

At night, especially in winter months and at times of low solar activity, the lower ionospheric D layer virtually disappears. When this happens, MW radio waves can easily be received many hundreds or even thousands of miles away as the signal will be reflected by the higher F layer.

This can allow very long-distance broadcasting, but can also interfere with distant local stations. Due to the limited number of available channels in the MW broadcast band, the same frequencies are re-allocated to different broadcasting stations several hundred miles apart.

On nights of good skywave propagation, the skywave signals of a distant station may interfere with the signals of local stations on the same frequency. Early transmitters were technically crude and virtually impossible to set accurately on their intended frequency and if as frequently happened two or more stations in the same part of the country broadcast simultaneously the resultant interference meant that usually neither could be heard clearly.

The Commerce Department rarely intervened in such cases but left it up to stations to enter into voluntary timesharing agreements amongst themselves. The addition of a third "entertainment" wavelength, meters, [3] did little to solve this overcrowding. In , the Commerce Department realized that as more and more stations were applying for commercial licenses, it was not practical to have every station broadcast on the same three wavelengths.

Class A and B stations were segregated into sub-bands. Both provide adequate audio quality for voice , but are insufficient for high-fidelity broadcasting, which is common on the VHF FM bands. Those stations which shut down completely at night are often known as "daytimers". Similar regulations are in force for Canadian stations, administered by Industry Canada ; however, daytimers no longer exist in Canada, the last station having signed off in , after migrating to the FM band.

The power limit can also be depending on daytime and it is possible, that a station may not work at nighttime, because it would then produce too much interference. Other countries may only operate low-powered transmitters on the same frequency, again subject to agreement. International mediumwave broadcasting in Europe has decreased markedly with the end of the Cold War and the increased availability of satellite and Internet TV and radio, although the cross-border reception of neighbouring countries' broadcasts by expatriates and other interested listeners still takes place.

These transmitters are carefully synchronized to minimize interference from more distant transmitters on the same frequency. Overcrowding on the Medium wave band is a serious problem in parts of Europe contributing to the early adoption of VHF FM broadcasting by many stations particularly in Germany. In Germany, almost all Medium wave public-radio broadcasts were discontinued between and to cut costs and save energy, [9] with the last such remaining programme Deutschlandradio being switched off on 31 December In The Netherlands all national and regional medium wave stations public and commercial were discontinued between and The last station that powered down its medium wave transmitter was Groot Nieuws Radio on 31 December [11].

All that is left on the medium wave is a handful of low powered medium wave radio stations maximum output power is W. Stereo transmission is possible and offered by some stations in the U. However, there have been multiple standards for AM stereo. C-QUAM is the official standard in the United States as well as other countries, but receivers that implement the technology are no longer readily available to consumers. Used receivers with AM Stereo can be found. For broadcasting, mast radiators are the most common type of antenna used, consisting of a steel lattice guyed mast in which the mast structure itself is used as the antenna.

Usually mast antennas are series-excited base driven ; the feedline is attached to the mast at the base. The base of the antenna is at high electrical potential and must be supported on a ceramic insulator to isolate it from the ground. Shunt-excited masts, in which the base of the mast is at a node of the standing wave at ground potential and so does not need to be insulated from the ground, have fallen into disuse, except in cases of exceptionally high power, 1 MW or more, where series excitation might be impractical.

If grounded masts or towers are required, cage or long-wire aerials are used. Another possibility consists of feeding the mast or the tower by cables running from the tuning unit to the guys or crossbars at a certain height. Directional aerials consist of multiple masts , which need not to be of the same height. It is also possible to realize directional aerials for mediumwave with cage aerials where some parts of the cage are fed with a certain phase difference.

Because such tall masts can be costly and uneconomic, other types of antennas are often used, which employ capacitive top-loading electrical lengthening to achieve equivalent signal strength with vertical masts shorter than a quarter wavelength. A popular choice for lower-powered stations is the umbrella antenna , which needs only one mast one-tenth wavelength or less in height.

This antenna uses a single mast insulated from ground and fed at the lower end against ground. At the top of the mast, radial top-load wires are connected usually about six which slope downwards at an angle of 40—45 degrees as far as about one-third of the total height, where they are terminated in insulators and thence outwards to ground anchors.

Thus the umbrella antenna uses the guy wires as the top-load part of the antenna. In all these antennas the smaller radiation resistance of the short radiator is increased by the capacitance added by the wires attached to the top of the antenna. In some rare cases dipole antennas are used, which are slung between two masts or towers. Such antennas are intended to radiate a skywave. Because at these frequencies atmospheric noise is far above the receiver signal to noise ratio , inefficient antennas much smaller than a wavelength can be used for receiving.

For reception at frequencies below 1. By far the most common antenna for broadcast reception is the ferrite-rod antenna , also known as a loopstick antenna. The high permeability ferrite core allows it to be compact enough to be enclosed inside the radio's case and still have adequate sensitivity. From Wikipedia, the free encyclopedia.
