The answer lies in the fact that we use radio spectrum for digital video broadcasting in television. These radio frequency spectra are used to transmit digital multiplex, which is a bundle of various television channels and other services by using 6-8 MHZ of bandwidth. Obviously, in terms of usage, digital broadcasting in television is making more efficient use of radio frequency spectrum as compared to analog broadcasting, which used the same bandwidth to broadcast only one program. This justifies the change in technology. At this important to mention that radio technology can be moved from analog to digital but it will take years to switch and grand scale technological preparations to make it happen.

There are many digital sound broadcasting technologies present that can provide good sound output with good reception like T-DAB, DRM+, DVB-T, DRM and DVB-T2; but none of these is satisfactory enough so as to replace the analog radio broadcasting. It is important to thoroughly take into account various technological aspects before switching from one technology to another. Factors like the new technology’s ability to provide good quality sound output, ability to receive signals and most importantly, its capacity to make efficient use of radio spectrum by broadcasting more radio channels.

FM radio requires a bandwidth of 250 kHz and capacity spacing of 100- 200 kHz, which varies from region to region. It is actually this different combination of bandwidth and capacity spacing which makes the technology switch from analog to digital, quite difficult. Therefore, we have to remain contented with analog radio broadcasting unless technology devises a solution for the existing problem.

It should be realized that desiring a change or up-gradation in technology does not only require determination, but there are many other technical aspects, which dictate the ability of technology to get upgraded. Along with huge finances, consistent efforts spread over a long period of time and undying determination, you have to have a reality check. There is no point in getting more sophisticated technology if it makes operations more difficult to handle, rather than making them easy. Same is the case with radio technology; we surely want to have digital broadcasting but with the current level of technology, it will not be wise to switch from analog to digital.

There are basically two standards used to compress audio and video data for digital video broadcasting. One is MPEG-2 which efficiently compresses various TV channels and services into a bundle. However, now MPEG-2 is superseded by MPEG-4. Its compressing standards for audio AAC and video AVC, work a lot more efficiently that MPEG-2. The comparative analysis of these two standards makes it evident, that MPEG-4 requires as less as half a bit rate than that of MPEG-2 to produce a high quality result. These standards are more defined as protocols, which highlights the fact it can be easily predicted, that there is going be further progress in terms of technology and performance by MPEG-4.

Several statistical multiplexing tools are employed to produce high quality video output. One such method is constant bit rate encoding, which is allocating a particular bandwidth of frequency to TV channels. Each bandwidth is unique for each channel. However, this encoding does not perform well at times of high demand, thus the video quality suffers. Although, the video data has a lot of redundancy and does not require much capacity in the bandwidth to get transferred, even then encoding makes the quality get deteriorated.

To get rid of the problems faced in constant bit rate encoding, technology has invented variable bit rate coding which does not let the picture quality suffer, even in high demand. In variable bit rate encoding, each channel is given a particular capacity of bandwidth to operate within, but if the need arises, the capacity can be increased so that the quality of the picture does not get deteriorated. In this regard, look ahead and feedback are two approaches which are employed to gauge the results.

It is vital to mention that variable bit rate encoding, when employed with compression standards like MPEG-4, can produce mind-blowing quality of both the sound and video output. It is due to these statistical tools that we are able to get different channels, without making the picture quality suffer. Moreover, with the advent of newer technologies like HDTV series and DVB multiplex, we are in a need to increase the multiplexing capacity of various tools.

For years single lens reflex cameras didn’t allow photographers to compose their images with the display screen. You had to use the viewfinder. This has been a concern for some beginner digital single lens reflex users until recently. Live View is not perfect, as there’s a extra step of directing the intended picture to a separate sensor. Then, instead of sending it to a primary sensor, it will be sent to the liquid crystal display screen, which can slow things down a bit. Initially auto focus was eliminated in place of Live View.

The “work on demand” time-table is extremely interesting to Albin, as he enjoys the meetings, designs and talking about customer and clientele requirements. Albin has also said that he did not know how his work had advanced so very much, and that came about as a big surprise to him.

Searching through Albin’s work, you will see the extensive range of media’s, prints and colours that he has mastered over the years. An individual would expect a person with a number of years of honing his skills to have got this down but this is beyond a talent, this is a new wave of illustration form with the same methods another designer can utilize but Albin uses a diverse set of skills to generate.

Albin’s client list is an example of how popular his work is. From businesses and companies such as Swatch,Loto-Quebec,Adidas, Ritzenhoff, Montreux Jazz Festival and many, many more.

These maps are created by using satellites or by using the remote sensation system. They are represented in the form of the consecutive triangles or squares. The first thing that you need to do before creating the digital terrain mapping is to take the survey of the area which is done by using the remote sensation system which will expose the landscape features excluding the forest covers and the cities which is done by either manually edit them or through some software.

The map which you create will be organized in the manner of series of unequal triangles or consecutive squares. The digital terrains mapping technique is used widely in almost most of the fields. Survey is the first step when creating a map using the Digital terrain mappings.

This has been considered as one of the supreme inventions as this has plenty of advantages and usefulness to the human kind. This technique is almost employed in virtually most of the industrial company to know about their pros and cons of the company.

Researchers are greatly benefited by this as this will be able to assist them greatly in order to gather the information that they require about the area that they are analyzing. Almost all the industries irrespective of their field are now using this method in order to improve their gain.

Some of the other application of this is to measure the gravity in a particular area, mapping the physical characteristics of the area, geomorphology etc. The quality of the map that you create using the digital terrain mapping will primarily depend on the interval that you give between the grids in your mapping and the source from which you are creating the mapping.

Planning will be made very easier as this will give a better insight and knowledge about the area so they will be able to modify their plan or their strategy according to the needs with the aid of the technology.

One can state numerous applications for digital terrains mapping method. This is really one of the wonderful discoveries made by the human beings to know more about the mother earth
