AAC Equipment

Nor can we fail to note that the quality of modern data transmission channels is constantly increasing, and often the simplest home ADSL-channel can be better and more reliable than a leased line connection. Kai-Fu Lee will not settle for partial explanations. And why use a cheap and s time-proven ADSL-connection as a backup link? When choosing a particular piece of equipment for transmitting sound over IP-based network is first necessary to decide: what tasks need to decide what your budget, what functions needed, and what can only be neglected in a given situation can be offered a specific solution. So what are the problems in the first approximation, can solve a set of equipment for transmitting sound over IP-based networks? The simplest and most lying on the surface response transmit sound in the "point-point", where both sides are fixed in space, such as studio and transmitter. There is a sound source, there is a receiver, arranged between IP-channel. Rent a certain bandwidth, select the appropriate format for audio compression (MDE, PCM, AAC, etc.) and you can work.

Another option is the output digital stream of sound in the public network, the Internet, for example, for the organization station. Let's see how it works. We have an ethereal sound source control. Required to organize the audio signal on the official website of the radio station. Anyone will be able to visit the site, click on the link and using the software player (WinAmp, Windows Media Player, Aimp, QuickTime, etc.) to play this stream on my computer. Note that modern mobile phones are also able to play Internet radio signals. Set the IP-coder connect its input to the output of air control, install and set up special software on the server. Encoder to encode audio information begins in the digital video (for example, in the format MDE) to transfer the site to the radio. This will allow listen to your radio anywhere and anytime, which is especially interesting. organize Internet broadcast can be without having frequencies in the air and even more so without a special radio transmission equipment.

Description And Configure A Mobile Client ICQ Jimm 0.6.2 .
by Tam

Just think, once for people to communicate with each other had to use paper (oh, horror!) By mail, carrier pigeons, telegraphs and other opulences modern museums. Everything changed with the times of dawn computer technology, and, subsequently, instant messaging services, in particular, icq. There is nothing easier than Record your friend to your contact list and start chatting. Quickly, conveniently, at virtually no cost. Details can be found by clicking AOL or emailing the administrator. And, with More recently, more and mobile.

Jimm 0.6.2 is a free client for instant messaging networks of icq, built on the technology of Java, and therefore compatible with all phones in the characteristics which had been on support for midp 2.0. (Which is virtually all the more realties actual models, but very very bad mammoths). One major advantage of Jimm is savings compared to communication through sms.Itak as well configured correctly Jimm (for example, version 0.6.2)? Include jimm, first of all go to Preferences in order to adjust the program, making possible its continued use of first introduce your account information from "Big" icq. This is done to Settings – Account. There simply enter our user id and password. If you do not have an account on icq, then press the right soft key and select the menu item to create a new account. After this perform the actions described above. Alternatively, you can register from any computer with installed icq and Internet access or online site icq.com. Particular attention should be paid to the settings menu under the name Network: the server name in this line by default are multiple servers that will program to identify your account.

Digital Configuration
by Tam

Note that a rough adjustment makes sense to hold on the most powerful channel, and the final fine-tuning – to the weakest. Making sure that you can not improve the picture, finally tighten all fasteners on the antenna, route the cable from the antenna to the site to view and install all the equipment in stand under the TV. In the case of the digital receiver to perform this operation much more difficult. The fact that the analog method has a very wide range of input levels – from when something becomes clear through interference, to the ideal reception. Moreover, the analog receiver fulfills input change instantly, changing the picture on the screen, respectively. Digital reception is characterized by the appearance of a threshold character image.

Transitional stage, when the image trembles and breaks, has a very narrow range of input signal levels. The situation is further complicated by the fact that the digital receiver is not an instant 'captures' the picture. He even sufficient level of input signal must be a few seconds for image processing. Therefore, we can offer the following options configure the system with a digital receiver. First, you can borrow anywhere analog Receiver settings. On the most popular satellite groups, such as Hot Bird 1,2,3,4,6; Eutelsat W4/Sesat; Astra-1 B, C, D, E, F, G, H, 2C; Thor-2, 3 / Intelsat-707, currently there are both digital and analog TV channels. After setting up an antenna "by analogy" You can connect digital equipment.

If the analog receiver to take no place, there remains the option of setting the signal level meter. It should be remembered that satmetr can be connected to the converter cable segment is not longer than a few meters. With the cable in a few tens of meters satmetr 'does not pull. " Most models of digital satellite receivers have built-in digital signal level meter. Although it is rather crude measures of, but the setup process, they make it easy. In the case of setting the level of the signal is particularly important accurate azimuth setting. Satellites in geostationary orbit located a few degrees. Therefore, adjust the signal level on the wrong satellite and set the parameters of digital signal (frequency, SR, FEC), you will not see anything, and realize that you have configured incorrectly, it will be very difficult. Much expand your ability to foster a satellite positioning system unit with the different satellites. Such a system allows you to receive up to 100 or more analog channels and many more digital. Consider antenna design, which can be configured for multiple satellites. This dish is different suspension design, which is called the 'polar'. Invention of this suspension was for astronomical instruments and has this name, because the axis around which the mirror antenna, parallel to the axis of rotation of the Earth. And it is known, is aimed at Polaris. Suspension design in the most general terms is shown in Fig. 10 and 11. In this Configuration angle of elevation of the polar axis is approximately equal to the absolute value of latitude point of the antenna. Amendment 'about' arises from the fact that the Earth is not perfectly spherical shape, and flattened by the poles. Elevation is selected from the calculation of directional antenna axis parallel to the equatorial plane. To turn the antenna axis in the direction of the satellites in geostationary orbit, a so-called correction, or the angle of declination. From simple geometrical considerations it is clear that these three angles add up to 900.
