HDTV - High Definition TV ? TV format of the future
More and more device in our day support HDTV - High Definition TV, in that at this time the front part of scientific research in the field of television occupied large mass of minds. Develop this direction everyone who earns money on the delivery of information to potential users (this can be just advertising and news and everything for which you pay money).
Development this direction is slightly crooked, first released a huge number of device capable of operating with HDTV - High Definition TV, and then began to implement the data system.
Now all over the world are transitioning to new standards in TV, the picture quality is far superior, excellent clarity and to convey such a signal is easier and cheaper.
Under such technology is actively creating HD content, the plants are in full working and create HD equipment, chain works. According to the results of the implementation of the new standard is more or less successfully. For receiving and transmitting images in digital form on the device broadcasts high-definition requires special software, which inherently needs to simplify the process of transition from a conventional digital broadcast TV high definition. It turns out that HDTV is a kind of intermediate, which will help to minimize costs and plays the role of catalyst transients. Probably not hard to understand why and what does it do TV signals can be transferred in different ways, but HDTV is the most difficult option since the digital signal in accordance with this standard has a wide bandwidth. If you learn how to transmit HDTV without much effort, then everything else will be a trifle.
the Sound can be passed and in place to do super sound thanks to Dolby Digital 5.1. The same image could be transferred with the highest clarity known to science. It will be possible in the future to compress the MPEG-2 format to the more efficient MPEG-4. If there is a desire to understand the difference, look at the speed data in different formats.
MPEG-2 if you transfer it over the network, you will need a channel with a bandwidth of 20 Mbit/s. But if you are already using MPEG-4 speed drops to 9 to 7 Mbps. The data flow is increasing from year to year and companies that transmit data is forced to turn to new technologies, to reduce the load on the network.m When you see on the screen film with high resolution, the person leading it will be possible to consider even the tiny pimples and wrinkles, and that leads to change and the technology of preparation of HD materials. HD TV will be much more widely used in view of the fact that the receiver will be easier to integrate the system of admission to any device will not be as hard as with the format (SDTV). If to consider the concept of such quality television, the transition from normal color to a regular high-definition television, can be compared with the transition from black & white to color image. The same grandiose distinction awaits all who try or create HD - ostrova transmission or reception, or to produce HD content for different audiences.
a couple of years ago, the company Informa Telecoms&Media conducted research in this direction and were known to 151 million domestic television receivers already used in varying degrees HDTV-servicemy. The second year the audience of users of HD services is growing rapidly and all because in the race and joined Russia and CIS countries. The first country which probably will switch to the new tariff is Finland, and possibly the Netherlands. the
future TV Chagall would the World more actively if there were difficulties. Content HD content" is still very small, the network is still very late in the growth of bandwidth and the lack of digital terrestrial broadcasting.
